  abstract  = {Most of the microelectronic circuits fabricated today are synchronous, i.e. they are driven by one or several clock signals. Synchronous circuit design faces several fundamental challenges such as high-speed clock distribution, integration of multiple cores operating at different clock rates, reduction of power consumption and dealing with voltage, temperature, manufacturing and runtime variations. Asynchronous or clockless design plays a key role in alleviating these challenges, however the design and test of asynchronous circuits is much more difficult in comparison to their synchronous counterparts. A driving force for a widespread use of asynchronous technology is the availability of mature EDA (Electronic Design Automation) tools which provide an entire automated design flow starting from an HDL (Hardware Description Language) specification yielding the final circuit layout. Even though there was much progress in developing such EDA tools for asynchronous circuit design during the last two decades, the maturity level as well as the acceptance of them is still not comparable with tools for synchronous circuit design. In particular, logic synthesis (which implies the application of Boolean minimisation techniques) for the entire system's control path can significantly improve the efficiency of the resulting asynchronous implementation, e.g. in terms of chip area and performance. However, logic synthesis, in particular for asynchronous circuits, suffers from complexity problems. Signal Transitions Graphs (STGs) are labelled Petri nets which are a widely used to specify the interface behaviour of speed independent (SI) circuits - a robust subclass of asynchronous circuits. STG decomposition is a promising approach to tackle complexity problems like state space explosion in logic synthesis of SI circuits. The (structural) decomposition of STGs is guided by a partition of the output signals and generates a usually much smaller component STG for each partition member, i.e. a component STG with a much smaller state space than the initial specification. However, decomposition can result in component STGs that in isolation have so-called irreducible CSC conflicts (i.e. these components are not SI synthesisable anymore) even if the specification has none of them. A new approach is presented to avoid such conflicts by introducing internal communication between the components. So far, STG decompositions are guided by the finest output partitions, i.e. one output per component. However, this might not yield optimal circuit implementations. Efficient heuristics are presented to determine coarser partitions leading to improved circuits in terms of chip area. For the new algorithms correctness proofs are given and their implementations are incorporated into the decomposition tool DESIJ. The presented techniques are successfully applied to some benchmarks - including 'real-life' specifications arising in the context of control resynthesis - which delivered promising results.},

  abstract  = {Diese von der Wirtschafts- und Sozialwissenschaftlichen Fakult{\"a}t der Universit{\"a}t Potsdam angenommene Dissertation thematisiert die Selbstorganisation von Migranten in eigenen Sportvereinen und auf anderen Ebenen des Vereinssports. Sie beruht auf den Ergebnissen eines vom Bundesinstitut f{\"u}r Sportwissenschaft gef{\"o}rderten Forschungsprojekts der Universit{\"a}t Potsdam. Mit mehreren hundert Migrantensportvereinen in ganz Deutschland stellt der Sport einen der wichtigsten Gesellschaftsbereiche f{\"u}r die Selbstorganisation von Zuwanderern dar. Doch obwohl sich Migranten in der Bundesrepublik schon seit den 1960er Jahren in eigenen Sportvereinen zusammenschließen, ist das Thema zuvor noch nicht umfassend untersucht worden. Um diese Forschungsl{\"u}cke zu schließen, stellt die Arbeit Basisinformationen {\"u}ber verschiedene Organisationsformen, typische Entstehungszusammenh{\"a}nge, spezifische Problemfelder sowie wiederkehrende Konfliktmuster bereit und pr{\"a}sentiert darauf aufbauende Annahmen {\"u}ber die Wirkungen der sportbezogenen Selbstorganisation auf das Verh{\"a}ltnis von Einheimischen und Zuwanderern im Sport, auf die allgemeinen interethnischen Beziehungen und auf den gesamtgesellschaftlichen Integrationsprozess. Daran ankn{\"u}pfend werden m{\"o}gliche Konsequenzen aufgezeigt, die die verschiedenen Akteure des Sportsystems aus den dargestellten Forschungsbefunden ziehen k{\"o}nnen. Die Arbeit basiert auf den Befunden einer in den Jahren 2006 bis 2009 durchgef{\"u}hrten empirischen Untersuchung, in der verschiedene qualitative Methoden eingesetzt wurden, um das Forschungsfeld explorativ, ergebnisoffen und in einer m{\"o}glichst weiten Perspektive zu beleuchten. In erster Linie bestand diese Feldstudie in einer Interviewreihe, f{\"u}r die 25 Vertreter von Migrantensportvereinen sowie 15 Feldexperten aus verschiedenen Berufsgruppen und Organisationen in Leitfaden-Interviews befragt wurden. Erg{\"a}nzt wurde die Interviewstudie durch eine Zeitungsanalyse, f{\"u}r die sieben Tages- und Wochenzeitungen nach Artikeln zum Thema durchsucht wurden, sowie gezielte Feldbeobachtungen, etwa beim Besuch von Fußballspielen, bei Versammlungen und Festen sowie in Vereinsheimen. Dar{\"u}ber hinaus wurde eine umfangreiche Internetrecherche durchgef{\"u}hrt, bei der vor allem die Webseiten von {\"u}ber 65 Migrantensportvereinen in Augenschein genommen wurden. In allen Untersuchungsteilen war das Vorgehen des Verfassers stark an der Grounded-Theory-Methode orientiert. Die so gewonnenen Forschungsergebnisse deuten darauf hin, dass eigenst{\"a}ndige Migrantensportvereine, die als vorherrschende Form der sportbezogenen Selbstorganisation von Zuwanderern im Mittelpunkt der Arbeit stehen, aus komplexen gesellschaftlichen Inklusions-, Schließungs- sowie Segmentationsprozessen resultieren und interindividuell unterschiedliche Beteiligungsmotive ihrer Mitglieder aufnehmen. Sie stellen typischerweise multifunktionale Hybridorganisationen dar und erbringen f{\"u}r die beteiligten Migranten und deren lokale Gemeinschaften spezifische Integrations-, Repr{\"a}sentations- und Solidarleistungen, durch die sie sich signifikant von deutschen Sportvereinen und Migrantenorganisationen in anderen Sektoren abheben. Zugleich unterscheiden sich die Migrantensportvereine untereinander hinsichtlich Vereinst{\"a}tigkeit, Selbstverst{\"a}ndnis und Konfliktbeteiligung sehr stark. Ihre R{\"u}ckwirkung auf den Vereinssport als organisationales Feld, auf die interethnischen Beziehungen in anderen Gesellschaftsbereichen und auf den gesamtgesellschaftlichen Integrationsprozess ist den pr{\"a}sentierten Forschungsergebnissen zufolge gleichfalls sehr ambivalent. Einerseits erbringen Migrantenvereine nicht nur die gleichen gemeinn{\"u}tzigen Leistungen im Bereich der sozialen Integration wie andere Sportvereine auch, sondern entfalten dar{\"u}ber hinaus, indem sie die Integrationsf{\"a}higkeit ihrer Mitglieder erh{\"o}hen und Personen in den organisierten Sport einbeziehen, die sonst gar keinem Sportverein beitreten w{\"u}rden, spezifische Integrationswirkungen, die andere Sportvereine nicht aufweisen. Andererseits erh{\"o}ht die Selbstorganisation von Migranten in eigenen Sportvereinen soziale Distanzen und Spannungen zwischen Einheimischen und Zuwanderern, zumal Migrantensportvereine vor allem an den manchmal gewaltvollen Konflikten im Amateurfußball {\"u}berproportional h{\"a}ufig beteiligt sind. Dar{\"u}ber hinaus stellt ein relativ kleiner Teil der Migrantensportvereine wegen Organisationsdefiziten eine ernste Belastung f{\"u}r die T{\"a}tigkeit der Sportverb{\"a}nde dar. Pauschalisierende Negativbewertungen der Vereine werden vom Verfasser jedoch als ungerechtfertigt und nicht sachangemessen zur{\"u}ckgewiesen.},

  abstract  = {Das vorliegende Buch vergleicht Strategien biologischer Systeme mit milit{\"a}rischen Strategien. Die zentrale Fragestellung ist dabei darauf gerichtet, ob es neben systemischen Gemeinsamkeiten auch gemeinsame oder {\"a}hnliche Strukturmuster und {\"a}hnliche Prozessabl{\"a}ufe beispielsweise sowohl im biologischen Abwehrmechanismus des Immunsystems und bei Insektenstaaten als auch bei Prozessen im Milit{\"a}r gibt. Vor diesem Hintergrund klaffen in der Theorie der Strategie, speziell in den Milit{\"a}rwissenschaften L{\"u}cken, denn der Systemansatz wird nicht konsequent beachtet, wie in diesem Buch mehrfach nachgewiesen ist. Von einem allgemeinen Verst{\"a}ndnis der Strategie als bewusstem planerischem Vorgehen ist Abstand zu nehmen. Ausgehend von der Methode der Analogie und des Vergleichs wird im theoretischen Teil dieses Buches die Allgemeine Systemtheorie erl{\"a}utert. Dabei werden der Begriff der Strategie ebenso wie die Begriffe Struktur und Prozess und Ans{\"a}tze aus der Kriegsphilosophie von Clausewitz untersucht. Den Ausgangspunkt und schließlich auch wieder den Endpunkt der {\"U}berlegungen bilden neben dem notwendigen weiten Verst{\"a}ndnis von Strategie, vor allem der Begriff der Organisation, ihrer Umwelt und der in diesem Zusammenhang bestehenden Wechselwirkung. Sowohl die Wechselwirkung von Umwelt und System als auch ihre Abh{\"a}ngigkeit durch strukturelle Kopplung werden beschrieben. Das Zusammenspiel und die daraus entstehende Komplexit{\"a}t der f{\"u}nf Komponenten der Wahrnehmung, der Information und der F{\"u}hrung im Zusammenhang der Komponenten von Raum und Zeit in einem sozialen System lassen die klassische Ziel-Mittel-Zweck-Beziehung Clausewitz´scher Strategiedefinition verk{\"u}rzt erscheinen. Anhand eines kurzen Rekurses der Methoden der Sozialen Netzwerkanalyse (SNA) wird der breite und tiefgehende Analyserahmen der Messung und Transparenzerreichung in Organisationen vorgestellt. Die SNA wird als Auspr{\"a}gung der Netzwerk- und Graphentheorie, in die Allgemeine Systemtheorie integriert. Sie bildet eine zukunftsweisende Methode der Untersuchung von Netzwerken wie etwa dem Internet (Facebook, Xing etc.). Der aufgezeigte Theorierahmen bildet dabei zugleich eine Methode f{\"u}r den Systemvergleich und kann als Vorgehensmodell k{\"u}nftiger Strategieentwicklung genutzt werden. Der anschließende Systemvergleich wird mit mehreren Beispielen durchgef{\"u}hrt. Ausgehend von der Zelle als Grundeinheit werden Strukturen und Prozesse des Immunsystems mit solchen in milit{\"a}rischen Strukturen, weil sie im Lauf der Evolution enorme Leistungen in Reaktion, Anpassung und Optimierung vollbracht haben. Der Vergleich geht der Frage nach, ob in diesen Bereichen der Strategie und Organisation systemische Grundregeln existieren. Das Beispiel der Wechselwirkung zwischen Parasit und Wirt zeigt, dass jeder Fortschritt und Sieg angesichts der Systemeinbettung von Strategie nur relativ wirken kann. Die Analogie zwischen Viren und Bakterien sowie die Entwicklung des Begriffs der sozialen Mimikry f{\"u}hren zu einem erweiterten Verst{\"a}ndnis der Strategie von Terroristen in sozialen Systemen. Verdeutlicht wird das Grundschema des T{\"a}uschens und Eindringens in Systeme sowie die Beeinflussung und Umsteuerung von Prozessen und Strukturen in einem System durch Kommunikation und Implementation von Codes. Am Beispiel des Immunsystems und der Bildung verschiedener Kommunikations- und Steuerungsmechanismen von Zellsystemen sowie Beispielen von Schwarmbildung und der Organisation sozialer Insekten werden eine Vielzahl heuristischer Hinweise f{\"u}r neue Ans{\"a}tze f{\"u}r die Organisation von Streitkr{\"a}ften und ihrer Steuerung gefunden. Neben der Erarbeitung eines grundlegenden Strategiebegriffs anhand von Wahrnehmung und Selektion als Grundprozess der Erzeugung von Strategie wird eine differenzierte Betrachtung von Begriffen wie Redundanz und Robustheit sowie eine relativierende Sichtweise von Risiko, Gefahr und Schaden gewonnen. Der Vergleich mit dem Immunsystems zeigt einfache Beispiele der Informationsspeicherung und -{\"u}bertragung, die zudem Bypassf{\"a}higkeiten sowie dezentrale Eskalations- und Deeskalationsprinzipien veranschaulichen. Dies er{\"o}ffnet in Analogie dieser Prinzipien einen weiten Raum Sicherheitsarchitekturen zu {\"u}berdenken und neu zu strukturieren. Zudem kann die r{\"a}umliche Ausbreitung von Information und Kr{\"a}ften als ein gemeinsames Grundproblem der Entwicklung und Wirksamkeit von Strategien sowohl in der Natur, als auch im Milit{\"a}r identifiziert werden. Die Betrachtung zeigt zudem wie Zellen mit fehlgeleiteten Prozessen und Strukturen umgehen. Die Analogie deutet auf das Erfordernis einer Ver{\"a}nderung im Umgang mit Fehlern und ihrer R{\"u}ckf{\"u}hr- und Umkehrbarkeit im weitesten Sinne. Das Buch er{\"o}ffnet {\"u}berdies ein neues Verst{\"a}ndnis von Staat, Gewaltenteilung und Institutionen in einem sozialen System. Die Ergebnisse sind auch auf andere Forschungsbereiche, Organisationen und unterschiedlichste soziale Systeme {\"u}bertragbar. Es er{\"o}ffnet sich ein breites Anwendungsspektrum f{\"u}r k{\"u}nftige strategische Untersuchungen.},

  abstract  = {Von der Natur geschaffene Polymere faszinieren Polymerforscher durch ihre spezielle auf eine bestimmte Aufgabe ausgerichtete Funktionalit{\"a}t. Diese ergibt sich aus ihrer Bausteinabfolge uber die Ausbildung von Uberstrukturen. Dazu z{\"a}hlen zum Beispiel Proteine (Eiweiße), aus deren Gestalt sich wichtige Eigenschaften ergeben. Diese Struktureigenschaftsbeziehung gilt ebenso f{\"u}r funktionelle synthetische Makromolek{\"u}le. Demzufolge kann die Kontrolle der Monomersequenz in Polymeren bedeutend f{\"u}r die resultierende Form des Polymermolek{\"u}ls sein. Obwohl die Synthese von synthetischen Polymeren mit der Komplexit{\"a}t und der Gr{\"o}ße von Proteinen in absehbarer Zeit wahrscheinlich nicht gelingen wird, k{\"o}nnen wir von der Natur lernen, um neuartige Polymermaterialien mit definierten Strukturen (Sequenzen) zu synthetisieren. Deshalb ist die Entwicklung neuer und besserer Techniken zur Strukturkontrolle von großem Interesse f{\"u}r die Synthese von Makromolek{\"u}len, die perfekt auf ihre Funktion zugeschnitten sind. Im Gegensatz zu der Anzahl fortgeschrittener Synthesestrategien zum Design aus- gefallener Polymerarchitekturen - wie zum Beispiel Sterne oder baumartige Polymere (Dendrimere) - gibt es vergleichsweise wenig Ans{\"a}tze zur echten Sequenzkontrolle in synthetischen Polymeren. Diese Arbeit stellt zwei unterschiedliche Techniken vor, mit denen die Monomersequenz innerhalb eines Polymers kontrolliert werden kann. Gerade bei den großtechnisch bedeutsamen radikalischen Polymerisationen ist die Sequenzkontrolle schwierig, weil die chemischen Bausteine (Monomere) sehr reaktiv sind. Im ersten Teil dieser Arbeit werden die Eigenschaften zweier Monomere (Styrol und N-substituiertes Maleinimid) geschickt ausgenutzt, um in eine Styrolkette definierte und lokal scharf abgegrenzte Funktionssequenzen einzubauen. Uber eine kontrollierte radikalische Polymerisationsmethode (ATRP) wurden in einer Ein-Topf-Synthese {\"u}ber das N-substituierte Maleinimid chemische Funktionen an einer beliebigen Stelle der Polystyrolkette eingebaut. Es gelang ebenfalls, vier unterschiedliche Funktionen in einer vorgegebenen Sequenz in die Polymerkette einzubauen. Diese Technik wurde an zwanzig verschiedenen N-substituierten Maleinimiden getestet, die meisten konnten erfolgreich in die Polymerkette integriert werden. In dem zweiten in dieser Arbeit vorgestellten Ansatz zur Sequenzkontrolle, wurde der schrittweise Aufbau eines Oligomers aus hydrophoben und hydrophilen Segmenten (ω-Alkin-Carbons{\"a}ure bzw. α-Amin-ω-Azid-Oligoethylenglycol) an einem l{\"o}slichen Polymertr{\"a}ger durchgef{\"u}hrt. Das Oligomer konnte durch die geschickte Auswahl der Verkn{\"u}pfungsreaktionen ohne Schutzgruppenstrategie synthetisiert werden. Der l{\"o}sliche Polymertr{\"a}ger aus Polystyrol wurde mittels ATRP selbst synthetisiert. Dazu wurde ein Startreagenz (Initiator) entwickelt, das in der Mitte einen s{\"a}urelabilen Linker, auf der einen Seite die initiierende Einheit und auf der anderen die Ankergruppe f{\"u}r die Anbindung des ersten Segments tr{\"a}gt. Der l{\"o}sliche Polymertr{\"a}ger erm{\"o}glichte einerseits die schrittweise Synthese in L{\"o}sung. Andererseits konnten {\"u}bersch{\"u}ssige Reagenzien und Nebenprodukte zwischen den Reaktionsschritten durch F{\"a}llung in einem Nicht-L{\"o}sungsmittel einfach abgetrennt werden. Der Linker erm{\"o}glichte die Abtrennung des Oligomers aus jeweils drei hydrophoben und hydrophilen Einheiten nach der Synthese.},

  abstract  = {Im Mittelpunkt dieser Arbeit stehen virtuelle 3D-Stadtmodelle, die Objekte, Ph{\"a}nomene und Prozesse in urbanen R{\"a}umen in digitaler Form repr{\"a}sentieren. Sie haben sich zu einem Kernthema von Geoinformationssystemen entwickelt und bilden einen zentralen Bestandteil geovirtueller 3D-Welten. Virtuelle 3D-Stadtmodelle finden nicht nur Verwendung als Mittel f{\"u}r Experten in Bereichen wie Stadtplanung, Funknetzplanung, oder L{\"a}rmanalyse, sondern auch f{\"u}r allgemeine Nutzer, die realit{\"a}tsnah dargestellte virtuelle St{\"a}dte in Bereichen wie B{\"u}rgerbeteiligung, Tourismus oder Unterhaltung nutzen und z. B. in Anwendungen wie GoogleEarth eine r{\"a}umliche Umgebung intuitiv erkunden und durch eigene 3D-Modelle oder zus{\"a}tzliche Informationen erweitern. Die Erzeugung und Darstellung virtueller 3D-Stadtmodelle besteht aus einer Vielzahl von Prozessschritten, von denen in der vorliegenden Arbeit zwei n{\"a}her betrachtet werden: Texturierung und Visualisierung. Im Bereich der Texturierung werden Konzepte und Verfahren zur automatischen Ableitung von Fototexturen aus georeferenzierten Schr{\"a}gluftbildern sowie zur Speicherung oberfl{\"a}chengebundener Daten in virtuellen 3D-Stadtmodellen entwickelt. Im Bereich der Visualisierung werden Konzepte und Verfahren f{\"u}r die multiperspektivische Darstellung sowie f{\"u}r die hochqualitative Darstellung nichtlinearer Projektionen virtueller 3D-Stadtmodelle in interaktiven Systemen vorgestellt. Die automatische Ableitung von Fototexturen aus georeferenzierten Schr{\"a}gluftbildern erm{\"o}glicht die Veredelung vorliegender virtueller 3D-Stadtmodelle. Schr{\"a}gluftbilder bieten sich zur Texturierung an, da sie einen Großteil der Oberfl{\"a}chen einer Stadt, insbesondere Geb{\"a}udefassaden, mit hoher Redundanz erfassen. Das Verfahren extrahiert aus dem verf{\"u}gbaren Bildmaterial alle Ansichten einer Oberfl{\"a}che und f{\"u}gt diese pixelpr{\"a}zise zu einer Textur zusammen. Durch Anwendung auf alle Oberfl{\"a}chen wird das virtuelle 3D-Stadtmodell fl{\"a}chendeckend texturiert. Der beschriebene Ansatz wurde am Beispiel des offiziellen Berliner 3D-Stadtmodells sowie der in GoogleEarth integrierten Innenstadt von M{\"u}nchen erprobt. Die Speicherung oberfl{\"a}chengebundener Daten, zu denen auch Texturen z{\"a}hlen, wurde im Kontext von CityGML, einem international standardisierten Datenmodell und Austauschformat f{\"u}r virtuelle 3D-Stadtmodelle, untersucht. Es wird ein Datenmodell auf Basis computergrafischer Konzepte entworfen und in den CityGML-Standard integriert. Dieses Datenmodell richtet sich dabei an praktischen Anwendungsf{\"a}llen aus und l{\"a}sst sich dom{\"a}nen{\"u}bergreifend verwenden. Die interaktive multiperspektivische Darstellung virtueller 3D-Stadtmodelle erg{\"a}nzt die gewohnte perspektivische Darstellung nahtlos um eine zweite Perspektive mit dem Ziel, den Informationsgehalt der Darstellung zu erh{\"o}hen. Diese Art der Darstellung ist durch die Panoramakarten von H. C. Berann inspiriert; Hauptproblem ist die {\"U}bertragung des multiperspektivischen Prinzips auf ein interaktives System. Die Arbeit stellt eine technische Umsetzung dieser Darstellung f{\"u}r 3D-Grafikhardware vor und demonstriert die Erweiterung von Vogel- und Fußg{\"a}ngerperspektive. Die hochqualitative Darstellung nichtlinearer Projektionen beschreibt deren Umsetzung auf 3D-Grafikhardware, wobei neben der Bildwiederholrate die Bildqualit{\"a}t das wesentliche Entwicklungskriterium ist. Insbesondere erlauben die beiden vorgestellten Verfahren, dynamische Geometrieverfeinerung und st{\"u}ckweise perspektivische Projektionen, die uneingeschr{\"a}nkte Nutzung aller hardwareseitig verf{\"u}gbaren, qualit{\"a}tssteigernden Funktionen wie z.~B. Bildraumgradienten oder anisotroper Texturfilterung. Beide Verfahren sind generisch und unterst{\"u}tzen verschiedene Projektionstypen. Sie erm{\"o}glichen die anpassungsfreie Verwendung g{\"a}ngiger computergrafischer Effekte wie Stilisierungsverfahren oder prozeduraler Texturen f{\"u}r nichtlineare Projektionen bei optimaler Bildqualit{\"a}t. Die vorliegende Arbeit beschreibt wesentliche Technologien f{\"u}r die Verarbeitung virtueller 3D-Stadtmodelle: Zum einen lassen sich mit den Ergebnissen der Arbeit Texturen f{\"u}r virtuelle 3D-Stadtmodelle automatisiert herstellen und als eigenst{\"a}ndige Attribute in das virtuelle 3D-Stadtmodell einf{\"u}gen. Somit tr{\"a}gt diese Arbeit dazu bei, die Herstellung und Fortf{\"u}hrung texturierter virtueller 3D-Stadtmodelle zu verbessern. Zum anderen zeigt die Arbeit Varianten und technische L{\"o}sungen f{\"u}r neuartige Projektionstypen f{\"u}r virtueller 3D-Stadtmodelle in interaktiven Visualisierungen. Solche nichtlinearen Projektionen stellen Schl{\"u}sselbausteine dar, um neuartige Benutzungsschnittstellen f{\"u}r und Interaktionsformen mit virtuellen 3D-Stadtmodellen zu erm{\"o}glichen, insbesondere f{\"u}r mobile Ger{\"a}te und immersive Umgebungen.},

  abstract  = {Lamine bilden zusammen mit laminassoziierten Proteinen die nukle{\"a}re Lamina. Diese ist notwendig f{\"u}r die mechanische Stabilit{\"a}t von Zellen, die Organisation des Chromatins, der Genexpression, dem Fortgang des Zellzyklus und der Zellmigration. Die vielf{\"a}ltigen Funktionen der Lamine werden durch die Pathogenese von Laminopathien belegt. Zu diesen Erkrankungen, welche ihre Ursache in Mutationen innerhalb der laminkodierenden Gene, oder der Gene laminassoziierter bzw. laminprozessierender Proteine haben, z{\"a}hlen unter anderem das „Hutchinson-Gilford Progerie Syndrom", die „Emery-Dreifuss" Muskeldystrophie und die dilatierte Kardiomyopathie. Trotz der fundamentalen Bedeutung der Lamine, wurden diese bisher nur in Metazoen und nicht in einzelligen Organismen detektiert. Der am{\"o}bide Organismus Dictyostelium discoideum ist ein haploider Eukaryot, der h{\"a}ufig als Modellorganismus in den verschiedensten Bereichen der Zellbiologie eingesetzt wird. Mit der Entdeckung von NE81, einem Protein das mit der inneren Kernh{\"u}lle von Dictyostelium discoideum assoziiert ist, wurde erstmals ein Protein identifiziert, dass man aufgrund seiner Eigenschaften als lamin{\"a}hnliches Protein in einem niederen Eukaryoten bezeichnen kann. Diese Merkmale umfassen die Existenz lamintypischer Sequenzen, wie die CDK1-Phosphorylierungsstelle, direkt gefolgt von einer zentralen „Rod"-Dom{\"a}ne, sowie eine typische NLS und die hoch konservierte CaaX-Box. F{\"u}r die Etablierung des NE81 als „primitives" Lamin, wurden im Rahmen dieser Arbeit verschiedene Experimente durchgef{\"u}hrt, die strukturelle und funktionelle Gemeinsamkeiten zu den Laminen in anderen Organismen aufzeigen konnten. Die Herstellung eines polyklonalen Antik{\"o}rpers erm{\"o}glichte die Verifizierung der subzellul{\"a}ren Lokalisation des NE81 durch Elektronenmikroskopie und gab Einblicke in das Verhalten des endogenen Proteins innerhalb des Zellzyklus. Mit der Generierung von NE81-Nullmutanten konnte demonstriert werden, dass NE81 eine wichtige Rolle bei der nukle{\"a}ren Integrit{\"a}t und der Chromatinorganisation von Zellen spielt. Des Weiteren f{\"u}hrte die Expression von zwei CaaX-Box deletierten NE81 - Varianten dazu, den Einfluss des Proteins auf die mechanische Stabilit{\"a}t der Zellen nachweisen zu k{\"o}nnen. Auch die Bedeutung der hochkonservierten CaaX-Box f{\"u}r die Lokalisation des Proteins wurde durch die erhaltenen Ergebnisse deutlich. Mit der Durchf{\"u}hrung von FRAP-Experimente konnte außerdem die strukturgebende Funktion von NE81 innerhalb des Zellkerns bekr{\"a}ftigt werden. Zus{\"a}tzlich wurde im Rahmen dieser Arbeit damit begonnen, den Einfluss der Isoprenylcysteincarboxylmethyltransferase auf die Lokalisation des Proteins aufzukl{\"a}ren. Die Entdeckung eines lamin{\"a}hnlichen Proteins in einem einzelligen Organismus, der an der Schwelle zu den Metazoen steht, ist f{\"u}r die evolution{\"a}re Betrachtung der Entwicklung der sozialen Am{\"o}be und f{\"u}r die Erforschung der molekularen Basis von Laminopathien in einem einfachen Modellorganismus sehr interessant. Die Arbeit mit Dictyostelium discoideum k{\"o}nnte daher Wege aufzeigen, dass Studium der Laminopathien am Tiermodell drastisch zu reduzieren. In den letzten Jahren hat die Erforschung unbekannter Bestandteile des Centrosoms in Dictyostelium discoideum große Fortschritte gemacht. Eine zu diesem Zwecke von unserer Arbeitsgruppe durchgef{\"u}hrte Proteomstudie, f{\"u}hrte zur Identifizierung weiterer, potentiell centrosomaler Kandidatenproteine. Der zweite Teil dieser Arbeit besch{\"a}ftigt sich mit der Charakterisierung eines solchen Kandidatenproteins, dem CP75. Es konnte gezeigt werden, dass CP75 einen echten, centrosomalen Bestandteil darstellt, der mikrotubuli-unabh{\"a}ngig mit der Core Struktur des Zellorganells assoziiert ist. Weiterhin wurde deutlich, dass die Lokalisation am Centrosom in Abh{\"a}ngigkeit vom Zellzyklus erfolgt und CP75 vermutlich mit CP39, einem weiteren centrosomalen Core Protein, interagiert.},

  abstract  = {Soil moisture is a key state variable that controls runoff formation, infiltration and partitioning of radiation into latent and sensible heat. However, the experimental characterisation of near surface soil moisture patterns and their controls on runoff formation remains a challenge. This subject was one aspect of the BMBF-funded OPAQUE project (operational discharge and flooding predictions in head catchments). As part of that project the focus of this dissertation is on: (1) testing the methodology and feasibility of the Spatial TDR technology in producing soil moisture profiles along TDR probes, including an inversion technique of the recorded signal in heterogeneous field soils, (2) the analysis of spatial variability and temporal dynamics of soil moisture at the field scale including field experiments and hydrological modelling, (3) the application of models of different complexity for understanding soil moisture dynamics and its importance for runoff generation as well as for improving the prediction of runoff volumes. To fulfil objective 1, several laboratory experiments were conducted to understand the influence of probe rod geometry and heterogeneities in the sampling volume under different wetness conditions. This includes a detailed analysis on how these error sources affect retrieval of soil moisture profiles in soils. Concerning objective 2 a sampling strategy of two TDR clusters installed in the head water of the Wilde Weißeritz catchment (Eastern Ore Mountains, Germany) was used to investigate how well "the catchment state" can be characterised by means of distributed soil moisture data observed at the field scale. A grassland site and a forested site both located on gentle slopes were instrumented with two Spatial TDR clusters that consist of up to 39 TDR probes. Process understanding was gained by modelling the interaction of evapotranspiration and soil moisture with the hydrological process model CATFLOW. A field scale irrigation experiment was carried out to investigate near subsurface processes at the hillslope scale. The interactions of soil moisture and runoff formation were analysed using discharge data from three nested catchments: the Becherbach with a size of 2 km², the Rehefeld catchment (17 km²) and the superordinate Ammelsdorf catchment (49 km²). Statistical analyses including observations of pre-event runoff, soil moisture and different rainfall characteristics were employed to predict stream flow volume. On the different scales a strong correlation between the average soil moisture and the runoff coefficients of rainfall-runoff events could be found, which almost explains equivalent variability as the pre-event runoff. Furthermore, there was a strong correlation between surface soil moisture and subsurface wetness with a hysteretic behaviour between runoff soil moisture. To fulfil objective 3 these findings were used in a generalised linear model (GLM) analysis which combines state variables describing the catchments antecedent wetness and variables describing the meteorological forcing in order to predict event runoff coefficients. GLM results were compared to simulations with the catchment model WaSiM ETH. Hereby were the model results of the GLMs always better than the simulations with WaSiM ETH. The GLM analysis indicated that the proposed sampling strategy of clustering TDR probes in typical functional units is a promising technique to explore soil moisture controls on runoff generation and can be an important link between the scales. Long term monitoring of such sites could yield valuable information for flood warning and forecasting by identifying critical soil moisture conditions for the former and providing a better representation of the initial moisture conditions for the latter.},

  abstract  = {The present thesis was born and evolved within the RAdial Velocity Experiment (RAVE) with the goal of measuring chemical abundances from the RAVE spectra and exploit them to investigate the chemical gradients along the plane of the Galaxy to provide constraints on possible Galactic formation scenarios. RAVE is a large spectroscopic survey which aims to observe spectroscopically ~10^6 stars by the end of 2012 and measures their radial velocities, atmospheric parameters and chemical abundances. The project makes use of the UK Schmidt telescope at Australian Astronomical Observatory (AAO) in Siding Spring, Australia, equipped with the multiobject spectrograph 6dF. To date, RAVE collected and measured more than 450,000 spectra. The precision of the chemical abundance estimations depends on the reliability of the atomic and atmosphere parameters adopted (in particular the oscillator strengths of the absorption lines and the effective temperature, gravity, and metallicity of the stars measured). Therefore we first identified 604 absorption lines in the RAVE wavelength range and refined their oscillator strengths with an inverse spectral analysis. Then, we improved the RAVE stellar parameters by modifying the RAVE pipeline and the spectral library the pipeline rely on. The modifications removed some systematic errors in stellar parameters discovered during this work. To obtain chemical abundances, we developed two different processing pipelines. Both of them perform chemical abundances measurements by assuming stellar atmospheres in Local Thermodynamic Equilibrium (LTE). The first one determines elements abundances from equivalent widths of absorption lines. Since this pipeline showed poor sensibility on abundances relative to iron, it has been superseded. The second one exploits the chi^2 minimization technique between observed and model spectra. Thanks to its precision, it has been adopted for the creation of the RAVE chemical catalogue. This pipeline provides abundances with uncertains of about ~0.2dex for spectra with signal-to-noise ratio S/N>40 and ~0.3dex for spectra with 20>S/N>40. For this work, the pipeline measured chemical abundances up to 7 elements for 217,358 RAVE stars. With these data we investigated the chemical gradients along the Galactic radius of the Milky Way. We found that stars with low vertical velocities |W| (which stay close to the Galactic plane) show an iron abundance gradient in agreement with previous works (~-0.07\$ dex kpc^-1) whereas stars with larger |W| which are able to reach larger heights above the Galactic plane, show progressively flatter gradients. The gradients of the other elements follow the same trend. This suggests that an efficient radial mixing acts in the Galaxy or that the thick disk formed from homogeneous interstellar matter. In particular, we found hundreds of stars which can be kinetically classified as thick disk stars exhibiting a chemical composition typical of the thin disk. A few stars of this kind have already been detected by other authors, and their origin is still not clear. One possibility is that they are thin disk stars kinematically heated, and then underwent an efficient radial mixing process which blurred (and so flattened) the gradient. Alternatively they may be a transition population" which represents an evolutionary bridge between thin and thick disk. Our analysis shows that the two explanations are not mutually exclusive. Future follow-up high resolution spectroscopic observations will clarify their role in the Galactic disk evolution.},

  abstract  = {Block copolymers are receiving increasing attention in the literature. Reports on amphiphilic block copolymers have now established the basis of their self-assembly behavior: aggregate sizes, morphologies and stability can be explained from the absolute and relative block lengths, the nature of the blocks, the architecture and also solvent selectiveness. In water, self-assembly of amphiphilic block copolymers is assumed to be driven by the hydrophobic. The motivation of this thesis is to study the influence on the self-assembly in water of A b B type block copolymers (with A hydrophilic) of the variation of the hydrophilicity of B from non-soluble (hydrophobic) to totally soluble (hydrophilic). Glucose-modified polybutadiene-block-poly(N-isopropylacrylamide) copolymers were prepared and their self-assembly behavior in water studied. The copolymers formed vesicles with an asymmetric membrane with a glycosylated exterior and poly(N-isopropylacrylamide) on the inside. Above the low critical solution temperature (LCST) of poly(N-isopropylacrylamide), the structure collapsed into micelles with a hydrophobic PNIPAM core and glycosylated exterior. This collapse was found to be reversible. As a result, the structures showed a temperature-dependent interaction with L-lectin proteins and were shown to be able to encapsulate organic molecules. Several families of double hydrophilic block copolymers (DHBC) were prepared. The blocks of these copolymers were biopolymers or polymer chimeras used in aqueous two-phase partition systems. Copolymers based on dextran and poly(ethylene glycol) blocks were able to form aggregates in water. Dex6500-b-PEG5500 copolymer spontaneously formed vesicles with PEG as the "less hydrophilic" barrier and dextran as the solubilizing block. The aggregates were found to be insensitive to the polymer's architecture and concentration (in the dilute range) and only mildly sensitive to temperature. Variation of the block length, yielded different morphologies. A longer PEG chain seemed to promote more curved aggregates following the inverse trend usually observed in amphiphilic block copolymers. A shorter dextran promoted vesicular structures as usually observed for the amphiphilic counterparts. The linking function was shown to have an influence of the morphology but not on the self-assembly capability in itself. The vesicles formed by dex6500-b-PEG5500 showed slow kinetics of clustering in the presence of Con A lectin. In addition both dex6500-b-PEG5500 and its crosslinked derivative were able to encapsulate fluorescent dyes. Two additional dextran-based copolymers were synthesized, dextran-b-poly(vinyl alcohol) and dextran-b-poly(vinyl pyrrolidone). The study of their self-assembly allowed to conclude that aqueous two-phase systems (ATPS) is a valid source of inspiration to conceive DHBCs capable of self-assembling. In the second part the principle was extended to polypeptide systems with the synthesis of a poly(N-hydroxyethylglutamine)-block-poly(ethylene glycol) copolymer. The copolymer that had been previously reported to have emulsifying properties was able to form vesicles by direct dissolution of the solid in water. Last, a series of thermoresponsive copolymers were prepared, dextran-b-PNIPAMm. These polymers formed aggregates below the LCST. Their structure could not be unambiguously elucidated but seemed to correspond to vesicles. Above the LCST, the collapse of the PNIPAM chains induced the formation of stable objects of several hundreds of nanometers in radius that evolved with increasing temperature. The cooling of these solution below LCST restored the initial aggregates. This self-assembly of DHBC outside any stimuli of pH, ionic strength, or temperature has only rarely been described in the literature. This work constituted the first formal attempt to frame the phenomenon. Two reasons were accounted for the self-assembly of such systems: incompatibility of the polymer pairs forming the two blocks (enthalpic) and a considerable solubility difference (enthalpic and entropic). The entropic contribution to the positive Gibbs free energy of mixing is believed to arise from the same loss of conformational entropy that is responsible for "the hydrophobic effect" but driven by a competition for water of the two blocks. In that sense this phenomenon should be described as the "hydrophilic effect".},

  abstract  = {The main objective of this thesis is to understand molecular crystallization as a multistep process with or without polymeric additives, including transient liquid-liquid phase separation, nanocrystal nucleation within the dense phase, and subsequent nanocrystal self-assembly or self-organization in sequence. The thesis starts with a quaternary model system, containing DL-Glutamic acid (Glu), polyethyleneimine (PEI), water, and EtOH, for the understanding of multistep precipitation of Glu with PEI as an additive. The experiments were performed by mixing Glu-PEI aqueous solution with a non-solvent EtOH. First, the phase diagram of the quaternary system is determined, obtaining precipitate, coacervates, or homogeneous mixtures by varying Glu/PEI w/w and water/EtOH v/v. Coacervation is observed to occur over a wide range of Glu/PEI with various volumes. The composition of coacervates is conveniently characterized by nuclear magnetic resonance spectroscopy. The observed coacervates are thermodynamically stable phases rich in solute, which is different from metastable polymer-induced liquid precursors. The combination of atomic force microscopy, small angle scattering, and ξ-potential measurements confirms the coexistence of monomers and Glu/PEI complexes and the aggregation of complexes in Glu-PEI-water systems. This suggests that there might be a direct structural transformation between the Glu-PEI complexes in aqueous solution and the metastable liquid precursors in a water-EtOH mixture. The multistep mechanism of Glu precipitation with PEI as an additive is investigated thereafter. The combination of stopped flow and small angle scattering demonstrates that the initially formed liquid precursors pass through an alteration of growth and coalescence. Combined with results from optical microscopy and scanning electron microscopy, the nucleation of nanoplatelets happens within each liquid precursor droplet, and nanoplatelets reorient themselves and self-organize into a radial orientation in the crystalline microspheres. The recipe was then extended to the precipitation of organics in other oppositely charged amino acid-polyelectrolyte systems. After the success in preparing hierarchical microspheres in solution, the similar recipe can be extended to the preparation of patterned thin films on substrate. By dipping a quaternary DL-Lys·HCl (Lys)-polyacrylic acid (PAA)-water-EtOH dispersion on a hydrophilic slide, the fast evaporation process of the volatile solvent EtOH is responsible for the homogeneous nucleation of NPs. Then, the following complete evaporation causes the mesocrystallization of a continuous spherulitic thin film along the receding line of the liquid, which again transforms into a mesocrystalline thin film. Furthermore, annealing is used to optimize the property of mesocrystalline thin films. As evaporation is a non-equilibrium process, it can be used to tune the kinetics of crystallization. Therefore, hierarchical or periodical thin films are obtainable by starting the evaporation from microspheres recrystallization, obtaining mesocrystalline thin films with 4 hierarchy levels. The results reveal that evaporation provides an easy but effective way for the formation of patterned structures via the positioning of NPs after their fast nucleation, resulting in different kinds of patterns by controlling the concentration of NPs, solvent evaporation rate, and other physical forces. Non-classical crystallization is not limited to crystallizations with polymeric additives. We also observed the nucleation and growth of a new molecular layer on the growing DL-Glu·H2O crystals from a supersaturated mother liquor by using an in-situ atomic force microscopy (AFM), where the nucleation and growth of a molecular layer proceed via amorphous nanoparticle (NP) attachment and relaxation process before the observation of the growth of a newly formed molecular layer. NP attachment to the crystal surface is too fast to observe by using in-situ AFM. The height shrinkage of NPs, combined to the structural transformation from 3D amorphous NPs to 2D crystalline layer, is observed during the relaxation process. The nucleation and growth of a newly formed molecular layer from NP relaxation is contradictory to the classical nucleation theory, which hypothesizes that nuclei show the same crystallographic properties as a bulk crystal. The formation of a molecular layer by NP attachment and relaxation rather than attachment of single molecules provides a different picture from the currently held classical nucleation and growth theory regarding the growth of single crystals from solution.},

Die magnetischen Eigenschaften der Eisenoxide sind materialabh{\"a}ngig aber begrenzt, weshalb nach anderen Verbindungen mit besseren Eigenschaften gesucht werden muss. Eisencarbid (Fe3C) kann eine dieser Verbindungen sein. Dieses besitzt vergleichbare positive Eigenschaften wie Eisenoxid, jedoch viel bessere magnetische Eigenschaften, speziell eine h{\"o}here S{\"a}ttigungsmagnetisierung. Bis jetzt wurde Fe3C haupts{\"a}chlich in Gasphasenabscheidungsprozessen synthetisiert oder als Nebenprodukt bei der Synthese von Kohlenstoffstrukturen gefunden.

Neben den Metallcarbiden k{\"o}nnen mit dieser Methode auch die entsprechenden Metallnitride synthetisiert werden, was die breite Anwendbarkeit der Methode unterstreicht.

  abstract  = {In this thesis chemical reactions under hydrothermal conditions were explored, whereby emphasis was put on green chemistry. Water at high temperature and pressure acts as a benign solvent. Motivation to work under hydrothermal conditions was well-founded in the tunability of physicochemical properties with temperature, e.g. of dielectric constant, density or ion product, which often resulted in surprising reactivity. Another cornerstone was the implementation of the principles of green chemistry. Besides the use of water as solvent, this included the employment of a sustainable feedstock and the sensible use of resources by minimizing waste and harmful intermediates and additives. To evaluate the feasibility of hydrothermal conditions for chemical synthesis, exemplary reactions were performed. These were carried out in a continuous flow reactor, allowing for precise control of reaction conditions and kinetics measurements. In most experiments a temperature of 200 °C in combination with a pressure of 100 bar was chosen. In some cases the temperature was even raised to 300 °C. Water in this subcritical range can also be found in nature at hydrothermal vents on the ocean floor. On the primitive earth, environments with such conditions were however present in larger numbers. Therefore we tested whether biologically important carbohydrates could be formed at high temperature from the simple, probably prebiotic precursor formaldehyde. Indeed, this formose reaction could be carried out successfully, although the yield was lower compared to the counterpart reaction under ambient conditions. However, striking differences regarding selectivity and necessary catalysts were observed. At moderate temperatures bases and catalytically active cations like Ca2+ are necessary and the main products are hexoses and pentoses, which accumulate due to their higher stability. In contrast, in high-temperature water no catalyst was necessary but a slightly alkaline solution was sufficient. Hexoses were only formed in negligible amounts, whereas pentoses and the shorter carbohydrates accounted for the major fraction. Amongst the pentoses there was some preference for the formation of ribose. Even deoxy sugars could be detected in traces. The observation that catalysts can be avoided was successfully transferred to another reaction. In a green chemistry approach platform chemicals must be produced from sustainable resources. Carbohydrates can for instance be employed as a basis. They can be transformed to levulinic acid and formic acid, which can both react via a transfer hydrogenation to the green solvent and biofuel gamma-valerolactone. This second reaction usually requires catalysis by Ru or Pd, which are neither sustainable nor low-priced. Under hydrothermal conditions these heavy metals could be avoided and replaced by cheap salts, taking advantage of the temperature dependence of the acid dissociation constant. Simple sulfate was recognized as a temperature switchable base. With this additive high yield could be achieved by simultaneous prevention of waste. In contrast to conventional bases, which create salt upon neutralization, a temperature switchable base becomes neutral again when cooled down and thus can be reused. This adds another sustainable feature to the high atom economy of the presented hydrothermal synthesis. In a last study complex decomposition pathways of biomass were investigated. Gas chromatography in conjunction with mass spectroscopy has proven to be a powerful tool for the identification of unknowns. It was observed that several acids were formed when carbohydrates were treated with bases at high temperature. This procedure was also applied to digest wood. Afterwards it was possible to fermentate the solution and a good yield of methane was obtained. This has to be regarded in the light of the fact that wood practically cannot be used as a feedstock in a biogas factory. Thus the hydrothermal pretreatment is an efficient means to employ such materials as well. Also the reaction network of the hydrothermal decomposition of glycine was investigated using isotope-labeled compounds as comparison for the unambiguous identification of unknowns. This refined analysis allowed the identification of several new molecules and pathways, not yet described in literature. In summary several advantages could be taken from synthesis in high-temperature water. Many catalysts, absolutely necessary under ambient conditions, could either be completely avoided or replaced by cheap, sustainable alternatives. In this respect water is not only a green solvent, but helps to prevent waste and preserves resources.},

  abstract  = {Nanoporous carbon materials are widely used in industry as adsorbents or catalyst supports, whilst becoming increasingly critical to the developing fields of energy storage / generation or separation technologies. In this thesis, the combined use of carbohydrate hydrothermal carbonisation (HTC) and templating strategies is demonstrated as an efficient route to nanostructured carbonaceous materials. HTC is an aqueous-phase, low-temperature (e.g. 130 - 200 °C) carbonisation, which proceeds via dehydration / poly-condensation of carbon precursors (e.g. carbohydrates and their derivatives), allowing facile access to highly functional carbonaceous materials. Whilst possessing utile, modifiable surface functional groups (e.g. -OH and -C=O-containing moieties), materials synthesised via HTC typically present limited accessible surface area or pore volume. Therefore, this thesis focuses on the development of fabrication routes to HTC materials which present enhanced textural properties and well-defined porosity. In the first discussed synthesis, a combined hard templating / HTC route was investigated using a range of sacrificial inorganic templates (e.g. mesoporous silica beads and macroporous alumina membranes (AAO)). Via pore impregnation of mesoporous silica beads with a biomass-derived carbon source (e.g. 2-furaldehyde) and subsequent HTC at 180 oC, an inorganic / carbonaceous hybrid material was produced. Removal of the template component by acid etching revealed the replication of the silica into mesoporous carbonaceous spheres (particle size ~ 5 μm), representing the inverse morphological structure of the original inorganic body. Surface analysis (e.g. FTIR) indicated a material decorated with hydrophilic (oxygenated) functional groups. Further thermal treatment at increasingly elevated temperatures (e.g. at 350, 550, 750 oC) under inert atmosphere allowed manipulation of functionalities from polar hydrophilic to increasingly non-polar / hydrophobic structural motifs (e.g. extension of the aromatic / pseudo-graphitic nature), thus demonstrating a process capable of simultaneous control of nanostructure and surface / bulk chemistry. As an extension of this approach, carbonaceous tubular nanostructures with controlled surface functionality were synthesised by the nanocasting of uniform, linear macropores of an AAO template (~ 200 nm). In this example, material porosity could be controlled, showing increasingly microporous tube wall features as post carbonisation temperature increased. Additionally, by taking advantage of modifiable surface groups, the introduction of useful polymeric moieties (i.e. grafting of thermoresponsive poly(N-isopropylacrylamide)) was also demonstrated, potentially enabling application of these interesting tubular structures in the fields of biotechnology (e.g. enzyme immobilization) and medicine (e.g. as drug micro-containers). Complimentary to these hard templating routes, a combined HTC / soft templating route for the direct synthesis of ordered porous carbonaceous materials was also developed. After selection of structural directing agents and optimisation of synthesis composition, the F127 triblock copolymer (i.e. ethylene oxide (EO)106 propylene oxide (PO)70 ethylene oxide (EO)106) / D-Fructose system was extensively studied. D-Fructose was found to be a useful carbon precursor as the HTC process could be performed at 130 oC, thus allowing access to stable micellular phase. Thermolytic template removal from the synthesised ordered copolymer / carbon composite yielded functional cuboctahedron single crystalline-like particles (~ 5 μm) with well ordered pore structure of a near perfect cubic Im3m symmetry. N2 sorption analysis revealed a predominantly microporous carbonaceous material (i.e. Type I isotherm, SBET = 257 m2g-1, 79 \% microporosity) possessing a pore size of ca. 0.9 nm. The addition of a simple pore swelling additive (e.g. trimethylbenzene (TMB)) to this system was found to direct pore size into the mesopore size domain (i.e. Type IV isotherm, SBET = 116 m2g-1, 60 \% mesoporosity) generating pore size of ca. 4 nm. It is proposed that in both cases as HTC proceeds to generate a polyfuran-like network, the organised block copolymer micellular phase is essentially "templated", either via hydrogen bonding between hydrophilic poly(EO) moiety and the carbohydrate or via hydrophobic interaction between hydrophobic poly(PO) moiety and forming polyfuran-like network, whilst the additive TMB presumably interact with poly(PO) moieties, thus swelling the hydrophobic region expanding the micelle template size further into the mesopore range.},

  abstract  = {Polymers which are sensitive towards external physical, chemical and electrical stimuli are termed as 'intelligent materials' and are widely used in medical and engineering applications. Presently, polymers which can undergo a physical change when heat is applied at a certain temperature (cloud point) in water are well-studied for this property in areas of separation chemistry, gene and drug delivery and as surface modifiers. One example of such a polymer is the poly (N-isopropylacrylamide) PNIPAAM, where it is dissolved well in water below 32 oC, while by increasing the temperature further leads to its precipitation. In this work, an alternative polymer poly (2-(2-methoxy ethoxy)ethyl methacrylate-co- oligo(ethylene glycol) methacrylate) (P(MEO2MA-co-OEGMA)) is studied due to its biocompatibility and the ability to vary its cloud points in water. When a layer of temperature responsive polymer was attached to a single continuous porous piece of silica-based material known as a monolith, the thermoresponsive characteristic was transferred to the column surfaces. The hybrid material was demonstrated to act as a simple temperature 'switch' in the separation of a mixture of five steroids under water. Different analytes were observed to be separated under varying column temperatures. Furthermore, more complex biochemical compounds such as proteins were also tested for separation. The importance of this work is attributed to separation processes utilizing environmentally friendly conditions, since harsh chemical environments conventionally used to resolve biocompounds could cause their biological activities to be rendered inactive.},

  abstract  = {Conventional energy sources are diminishing and non-renewable, take million years to form and cause environmental degradation. In the 21st century, we have to aim at achieving sustainable, environmentally friendly and cheap energy supply by employing renewable energy technologies associated with portable energy storage devices. Lithium-ion batteries can repeatedly generate clean energy from stored materials and convert reversely electric into chemical energy. The performance of lithium-ion batteries depends intimately on the properties of their materials. Presently used battery electrodes are expensive to be produced; they offer limited energy storage possibility and are unsafe to be used in larger dimensions restraining the diversity of application, especially in hybrid electric vehicles (HEVs) and electric vehicles (EVs). This thesis presents a major progress in the development of LiFePO4 as a cathode material for lithium-ion batteries. Using simple procedure, a completely novel morphology has been synthesized (mesocrystals of LiFePO4) and excellent electrochemical behavior was recorded (nanostructured LiFePO4). The newly developed reactions for synthesis of LiFePO4 are single-step processes and are taking place in an autoclave at significantly lower temperature (200 deg. C) compared to the conventional solid-state method (multi-step and up to 800 deg. C). The use of inexpensive environmentally benign precursors offers a green manufacturing approach for a large scale production. These newly developed experimental procedures can also be extended to other phospho-olivine materials, such as LiCoPO4 and LiMnPO4. The material with the best electrochemical behavior (nanostructured LiFePO4 with carbon coating) was able to delive a stable 94\% of the theoretically known capacity.},

  abstract  = {The creation of complex polymer structures has been one of the major research topics over the last couple of decades. This work deals with the synthesis of (block co-)polymers, the creation of complex and stimuli-responsive aggregates by self-assembly, and the cross-linking of these structures. Also the higher-order self-assembly of the aggregates is investigated. The formation of poly-2-oxazoline based micelles in aqueous solution and their simultaneous functionalization and cross-linking using thiol-yne chemistry is e.g. presented. By introducing pH responsive thiols in the core of the micelles the influence of charged groups in the core of micelles on the entire structure can be studied. The charging of these groups leads to a swelling of the core and a decrease in the local concentration of the corona forming block (poly(2-ethyl-2-oxazoline)). This decrease in concentration yields a shift in the cloud point temperature to higher temperatures for this Type I thermoresponsive polymer. When the swelling of the core is prohibited, e.g. by the introduction of sufficient amounts of salt, this behavior disappears. Similar structures can be prepared using complex coacervate core micelles (C3Ms) built through the interaction of weakly acidic and basic polymer blocks. The advantage of these structures is that two different stabilizing blocks can be incorporated, which allows for more diverse and complex structures and behavior of the micelles. Using block copolymers with either a polyanionic or a polycationic block C3Ms could be created with a corona which contains two different soluble nonionic polymers, which either have a mixed corona or a Janus type corona, depending on the polymers that were chosen. Using NHS and EDC the micelles could easily be cross-linked by the formation of amide bonds in the core of the micelles. The higher-order self-assembly behavior of these core cross-linked complex coacervate core micelles (C5Ms) was studied. Due to the cross-linking the micelles are stabilized towards changes in pH and ionic strength, but polymer chains are also no longer able to rearrange. For C5Ms with a mixed corona likely network structures were formed upon the collapse of the thermoresponsive poly(N-isopropylacrylamide) (PNIPAAm), whereas for Janus type C5Ms well defined spherical aggregates of micelles could be obtained, depending on the pH of the solution. Furthermore it could be shown that Janus micelles can adsorb onto inorganic nanoparticles such as colloidal silica (through a selective interaction between PEO and the silica surface) or gold nanoparticles (by the binding of thiol end-groups). Asymmetric aggregates were also formed using the streptavidin-biotin binding motive. This is achieved by using three out of the four binding sites of streptavidin for the binding of one three-arm star polymer, end-functionalized with biotin groups. A homopolymer with one biotin end-group can be used to occupy the last position. This binding of two different polymers makes it possible to create asymmetric complexes. This phase separation is theoretically independent of the kind of polymer since the structure of the protein is the driving force, not the intrinsic phase separation between polymers. Besides Janus structures also specific cross-linking can be achieved by using other mixing ratios.},

  abstract  = {The needs for sustainable energy generation, but also a sustainable chemistry display the basic motivation of the current thesis. By different single investigated cases, which are all related to the element carbon, the work can be devided into two major topics. At first, the sustainable synthesis of "useful" carbon materials employing the process of hydrothermal carbonisation (HC) is described. In the second part, the synthesis of heteroatom - containing carbon materials for electrochemical and fuel cell applications employing ionic liquid precursors is presented. On base of a thorough review of the literature on hydrothermolysis and hydrothermal carbonisation of sugars in addition to the chemistry of hydroxymethylfurfural, mechanistic considerations of the formation of hydrothermal carbon are proposed. On the base of these reaction schemes, the mineral borax, is introduced as an additive for the hydrothermal carbonisation of glucose. It was found to be a highly active catalyst, resulting in decreased reaction times and increased carbon yields. The chemical impact of borax, in the following is exploited for the modification of the micro- and nanostructure of hydrothermal carbon. From the borax - mediated aggregation of those primary species, widely applicable, low density, pure hydrothermal carbon aerogels with high porosities and specific surface areas are produced. To conclude the first section of the thesis, a short series of experiments is carried out, for the purpose of demonstrating the applicability of the HC model to "real" biowaste i.e. watermelon waste as feedstock for the production of useful materials. In part two cyano - containing ionic liquids are employed as precursors for the synthesis of high - performance, heteroatom - containing carbon materials. By varying the ionic liquid precursor and the carbonisation conditions, it was possible to design highly active non - metal electrocatalyst for the reduction of oxygen. In the direct reduction of oxygen to water (like used in polymer electrolyte fuel cells), compared to commercial platinum catalysts, astonishing activities are observed. In another example the selective and very cost efficient electrochemical synthesis of hydrogen peroxide is presented. In a last example the synthesis of graphitic boron carbon nitrides from the ionic liquid 1 - Ethyl - 3 - methylimidazolium - tetracyanoborate is investigated in detail. Due to the employment of unreactive salts as a new tool to generate high surface area these materials were first time shown to be another class of non - precious metal oxygen reduction electrocatalyst.},

  abstract  = {Mathematical modeling of biological phenomena has experienced increasing interest since new high-throughput technologies give access to growing amounts of molecular data. These modeling approaches are especially able to test hypotheses which are not yet experimentally accessible or guide an experimental setup. One particular attempt investigates the evolutionary dynamics responsible for today's composition of organisms. Computer simulations either propose an evolutionary mechanism and thus reproduce a recent finding or rebuild an evolutionary process in order to learn about its mechanism. The quest for evolutionary fingerprints in metabolic and gene-coexpression networks is the central topic of this cumulative thesis based on four published articles. An understanding of the actual origin of life will probably remain an insoluble problem. However, one can argue that after a first simple metabolism has evolved, the further evolution of metabolism occurred in parallel with the evolution of the sequences of the catalyzing enzymes. Indications of such a coevolution can be found when correlating the change in sequence between two enzymes with their distance on the metabolic network which is obtained from the KEGG database. We observe that there exists a small but significant correlation primarily on nearest neighbors. This indicates that enzymes catalyzing subsequent reactions tend to be descended from the same precursor. Since this correlation is relatively small one can at least assume that, if new enzymes are no "genetic children" of the previous enzymes, they certainly be descended from any of the already existing ones. Following this hypothesis, we introduce a model of enzyme-pathway coevolution. By iteratively adding enzymes, this model explores the metabolic network in a manner similar to diffusion. With implementation of an Gillespie-like algorithm we are able to introduce a tunable parameter that controls the weight of sequence similarity when choosing a new enzyme. Furthermore, this method also defines a time difference between successive evolutionary innovations in terms of a new enzyme. Overall, these simulations generate putative time-courses of the evolutionary walk on the metabolic network. By a time-series analysis, we find that the acquisition of new enzymes appears in bursts which are pronounced when the influence of the sequence similarity is higher. This behavior strongly resembles punctuated equilibrium which denotes the observation that new species tend to appear in bursts as well rather than in a gradual manner. Thus, our model helps to establish a better understanding of punctuated equilibrium giving a potential description at molecular level. From the time-courses we also extract a tentative order of new enzymes, metabolites, and even organisms. The consistence of this order with previous findings provides evidence for the validity of our approach. While the sequence of a gene is actually subject to mutations, its expression profile might also indirectly change through the evolutionary events in the cellular interplay. Gene coexpression data is simply accessible by microarray experiments and commonly illustrated using coexpression networks where genes are nodes and get linked once they show a significant coexpression. Since the large number of genes makes an illustration of the entire coexpression network difficult, clustering helps to show the network on a metalevel. Various clustering techniques already exist. However, we introduce a novel one which maintains control of the cluster sizes and thus assures proper visual inspection. An application of the method on Arabidopsis thaliana reveals that genes causing a severe phenotype often show a functional uniqueness in their network vicinity. This leads to 20 genes of so far unknown phenotype which are however suggested to be essential for plant growth. Of these, six indeed provoke such a severe phenotype, shown by mutant analysis. By an inspection of the degree distribution of the A.thaliana coexpression network, we identified two characteristics. The distribution deviates from the frequently observed power-law by a sharp truncation which follows after an over-representation of highly connected nodes. For a better understanding, we developed an evolutionary model which mimics the growth of a coexpression network by gene duplication which underlies a strong selection criterion, and slight mutational changes in the expression profile. Despite the simplicity of our assumption, we can reproduce the observed properties in A.thaliana as well as in E.coli and S.cerevisiae. The over-representation of high-degree nodes could be identified with mutually well connected genes of similar functional families: zinc fingers (PF00096), flagella, and ribosomes respectively. In conclusion, these four manuscripts demonstrate the usefulness of mathematical models and statistical tools as a source of new biological insight. While the clustering approach of gene coexpression data leads to the phenotypic characterization of so far unknown genes and thus supports genome annotation, our model approaches offer explanations for observed properties of the coexpression network and furthermore substantiate punctuated equilibrium as an evolutionary process by a deeper understanding of an underlying molecular mechanism.},

  abstract  = {The Casimir-Polder interaction between a single neutral atom and a nearby surface, arising from the (quantum and thermal) fluctuations of the electromagnetic field, is a cornerstone of cavity quantum electrodynamics (cQED), and theoretically well established. Recently, Bose-Einstein condensates (BECs) of ultracold atoms have been used to test the predictions of cQED. The purpose of the present thesis is to upgrade single-atom cQED with the many-body theory needed to describe trapped atomic BECs. Tools and methods are developed in a second-quantized picture that treats atom and photon fields on the same footing. We formulate a diagrammatic expansion using correlation functions for both the electromagnetic field and the atomic system. The formalism is applied to investigate, for BECs trapped near surfaces, dispersion interactions of the van der Waals-Casimir-Polder type, and the Bosonic stimulation in spontaneous decay of excited atomic states. We also discuss a phononic Casimir effect, which arises from the quantum fluctuations in an interacting BEC.},
