TY - THES A1 - Valverde Serrano, Clara T1 - Self-assembly behavior in hydrophilic block copolymers T1 - Selbstorganisation von hydrophilen Blockcopolymeren N2 - 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”. N2 - Blockcopolymere erfahren ein stetig wachsendes Interesse, was an der steigenden Anzahl an Publikationen zu diesem Thema erkennbar ist. Zahlreiche Studien zu amphiphilen Blockcopolymeren haben dabei einige grundlegende Erkenntnisse über deren chemisches und physikalisches Verhalten, vor allem über die Selbstorganisation, hervorgebracht. So können die Größe, die verschiedenen Morphologien und auch die Stabilität der gebildeten Aggregate anhand der relativen und absoluten Blocklängen, die chemischen Struktur der Blöcke, der molekularen Architektur und der Eigenschaften des verwendeten Lösungsmittel erklärt werden. Im speziellen Fall des Wassers als Lösungsmittel bist die Selbstorganisation amphiphiler Blockcopolymere durch den hydrophoben Effekt bedingt. Dieser Arbeit liegt das Interesse an der Selbstorganisation in wässrigem Medium von Blockcopolymeren des Typs A-b-B mit A als hydrophilem Block und B als Block mit variierender Hydrophilie bzw. Hydrophpobie von unlöslich bis vollständig löslich zugrunde. Durch Variation dieser Eigenschaften von Block B soll dessen Einfluss auf das Selbstorganisationsverhalten untersucht werden. Dazu wurden mit Glucose modifizierte Polybutadien-block-Poly(N-Isopropylacrylamid)-Copolymere hergestellt und deren Selbstorganisation in Wasser untersucht. Die Copolymere bilden Vesikel mit einer asymmetrischen Membran, wobei im äußeren Bereich glycolysierte Gruppen und im inneren Bereich Poly(N-Isopropylacrylamid) (PNIPAM) vorliegen. Beim Überschreiten der low critical solution temperature (LCST) kollabiert die vesikuläre Struktur unter Bildung von Mizellen mit einem hydrophoben PNIPAM-Mizellinneren und nach außen gerichteten glycolysierten Blöcken. Diese strukturelle Umwandlung ist reversibel. Die Strukturen zeigten außerdem eine temperaturabhängige Wechselwirkung mit L-Lectin-Proteinen und die Möglichkeit zur Einkapselung organischer Moleküle konnte belegt werden. Des weiteren wurden verschiedene Gruppen von Blockcopolymeren mit zwei hydrophilen Blöcken synthetisiert (double hydrophilic block copolymers – DHBC). Die Blöcke dieser Systeme waren entweder Biopolymere oder Polymerchimäre, die in wässrigen Zwei-Phasen-Trennverfahren eingesetzt werden. Polymere, die auf Dextran- und Poly(ethylenglycol)-Blöcken basieren, zeigen Aggregatbildung in wässriger Phase. Dex6500-b-PEG5500 bildet spontan Vesikel mit PEG als „weniger hydrophilem“ Bestandteil und Dextran als löslichem Block. Die Bildung dieser Vesikel zeigte keine Emfpindlichkeit gegenüber einer Veränderung der Polymerarchitektur und der Konzentration, und nur eine geringe Sensitivität gegenüber Temperaturänderungen. Veränderungen der Blocklängen dagegen beeinflussten die Selbstorganisation und führten zu unterschiedlichen Morphologien. Längere PEG-Blöcke bevorzugten dabei die Bildung eher gekrümmter Aggregate, entgegen dem Trend, der gewöhnlicherweise für amphiphile Blockcopolymere beobachtet wird. Die Verkürzung des Dextran-Blocks fördert die Ausbildung vesikulärer Strukturen, was dem Verhalten der amphiphilen Gegenspieler der DHBC-Systeme entspricht. Die funktionelle Gruppe zur Verbindung der beiden Blöcke hat zwar einen Einfluss auf die Morphologie der gebildeten Aggregate, nicht jedoch auf die eigentliche Fähigkeit der Systeme zur Selbstorganisation. Die Dex6500-b-PEG5500-Vesikel wiesen zudem eine langsame Bildungskinetik in Gegenwart von Con-A-Lectin auf. Des Weiteren waren sowohl Dex6500-b-PEG5500 als auch das quervernetzte Derivate dieses Copolymers in der Lage, Fluoreszenzfarbstoffe einzulagern. Um zu zeigen, dass wässrige Zwei-Phasen-Systeme (aqueous two phase systems – ATPS) eine belastbare Grundlage für die Untersuchung und Entwicklung selbstorganisierender DHBC-Systeme sind, wurden weitere Dextran-basierte Copolymere synthetsisiert: Dextran-b-Poly(vinylalokohol) und Detran-b-Poly(vinylpyrrolidon). In einem zweiten Teil dieser Arbeit wurde das zuvor erarbeitete Prinzip auf auf Polypeptidsysteme ausgeweitet. Dazu wurde ein Poly(N-Hydroxyethylglutamin)-block-Poly(ethylenglycol)-Copolymer hergestellt. Dieses Copolymer, dessen emulgierenden Eigenschaften bereits bekannt waren, wies unmittelbar nach Lösung des Feststoffes in Wasser Vesikelbildung auf. In einem dritten Teil der Studie wurden thermoresponsive Copolymere hergestellt und untersucht: Dextran-b-PNIPAMm. Unterhalb der LCST konnte die Bildung von Aggregaten nachgewiesen werden, deren Struktur nicht zweifelsfrei entschlüsselt werden konnte, wobei jedoch zahlreiche Hinweise auf eine vesikuläre Struktur hindeuten. Oberhalb der LCST wurde durch die Kollabierung der PNIPAM-Ketten die Bildung stabiler Strukturen mit Radien von mehreren hundert Nanometern induziert, deren weitere Entwicklung durch eine weitere Temperaturerhöhung gefördert werden konnte. Durch Rückkühlung in den Temperaturebereich unterhalb der LCST konnten die zuvor beobachteten Aggregate reversibel zurückgebildet werden. Das Selbstorganisationsverhalten von DHBC, unabhängig vom Einfluss des pH-Werts, der Ionenstärke oder der Temperatur are bisher nur in sehr geringem Umfang Gegenstand wissenschaftlicher Veröffentlichungen. Diese Arbeit stellt damit den ersten umfassenden Beitrag zur systematischen Erarbeitung dieses Phänomens dar. Es konnten dabei zwei Ursachen für die beobachteten Selbstorganisationseffekte bestimmt werden: die Inkompatibilität der beiden Polymerblöcke (enthalpischer Effekt) und der Unterschied in deren Löslichkeit (enthalpische und entropische Effekte). Der entropische Beitrag zur positiven Gibbs’schen Freien Mischungsenergie wird dem selben Verlust konformativer Entropie zugeordnet, der auch für den hydrophoben Effekt verantwortlich ist, allerdings angetrieben durch einen Wettbewerb der beiden Polymerblöcke um das Wasser. In diesem Sinne kann man das beobachtete Phänomen als „hydrophilen Effekt“ bezeichnen.

Taking the degradation of mRNA into account, we show theoretically that both the translation rate and the translational ratio decrease with increasing mRNA length, in agreement with available experimental data for the prokaryote Escherichia coli. We also show that, compared to prokaryotes, mRNA degradation in eukaryotes leads to a less rapid decrease of the translational ratio. This finding is consistent with the fact that, compared to prokaryotes, eukaryotes tend to have longer proteins.

Am. Chem. Soc., 2010, 132, 1831]. Using models of SAMs of increasing complexity (dimer, linear N-mers, and two-dimensionally arranged N-mers) and density functional theory on the (TD-) B3LYP/6-31G* level, we determine optical absorption spectra, the nature and magnitude of excitonic couplings, and the corresponding spectral shifts. It is found that at inter-monomer distances of about 20 angstrom and above, TD-B3LYP excitation frequencies (and signal intensities) can be well described by the frequently used point-dipole approximation. Further, calculated blue shifts in optical absorption spectra account for the experimental observations made for azobenzene/gold SAMs, and hint to the fact that they can indeed be responsible for reduced switching probability in densely packed self-assembled structures.

The simplest example consists of four oscillators, comprising two alternatively activated, due to an external periodic modulation, pairs. In terms of the stroboscopic Poincare map, the phase differences change according to an expanding Bernoulli map that depends on the coupling type. Several examples of hyperbolic chaos for different types of coupling are illustrated numerically.

Here, non-optimized (chloroform cast) and nearly optimized (solvent-annealed o-dichlorobenzene cast) P3HT:PCBM blend films treated over a range of annealing temperatures are studied via optical and photovoltaic device measurements. Parameters related to the P3HT aggregate morphology in the blend are obtained through a recently established analytical model developed by F. C. Spano for the absorption of weakly interacting H-aggregates. Thermally induced changes are related to the glass transition range of the blend. In the chloroform prepared devices, the improvement in device efficiency upon annealing within the glass transition range can be attributed to the growth of P3HT aggregates, an overall increase in the percentage of chain crystallinity, and a concurrent increase in the hole mobilities. Films treated above the glass transition range show an increase in efficiency and fill factor not only associated with the change in chain crystallinity, but also with a decrease in the energetic disorder. On the other hand, the properties of the P3HT phase in the solvent-annealed o-dichlorobenzene cast blends are almost indistinguishable from those of the corresponding pristine P3HT layer and are only weakly affected by thermal annealing. Apparently, slow drying of the blend allows the P3HT chains to crystallize into large domains with low degrees of intra- and interchain disorder. This morphology appears to be most favorable for the efficient generation and extraction of charges.

The implications of these results on aphasia tests could be significant and pose questions on the adequacy of such tools for testing non-literate individuals. Aiming at examining the impact of literacy on oral language processing and its implication on aphasia tests, this study tested 12 non-literate and 12 literate individuals with a modified Amharic version of the Bilingual Aphasia Test (Paradis and Amberber, 1991, Bilingual Aphasia Test. Amharic version. Hillsdale, NJ: Lawrence Erlbaum.). The problems of phonological awareness skills in oral language processing in non-literates are substantiated. In addition, compared with literate participants, non-literate individuals demonstrated difficulties in the word/sentence-picture matching tasks. This study has also revealed that the Amharic version of the Bilingual Aphasia Test may be viable for testing Amharic-speaking non-literate individuals with aphasia when modifications are incorporated.

Location: Brandenburg, NE Germany. Methods: The effect of wild ungulate grazing and browsing was studied in three successional stages: (1) Corynephorus canescens-dominated grassland; (2) ruderal tall forb vegetation dominated by Tanacetum vulgare; and (3) Pinus sylvestris-pioneer forest. The study was conducted over 3 yr. In each successional stage, six paired 4 m(2)-monitoring plots of permanently grazed versus ungrazed plots were arranged in three random blocks. Removal of grazing was introduced de novo for the study. In each plot, percentage cover of each plant and lichen species and total cover of woody plants was recorded. Results: Wild ungulates considerably affected successional pathways and species composition in open habitats but this influence became evident in alteration of abundances of only a few species. Grazing effects differed considerably between successional stages: species richness was higher in grazed versus ungrazed ruderal and pioneer forest plots, but not in the Corynephorus sites. Herbivory affected woody plant cover only in the Pioneer forest sites. Although the study period was too short to observe drastic changes in species richness and woody plant cover, notable changes in species composition were still detected in all successional stages. Conclusion: Wild ungulate browsing is a useful tool to inhibit encroachment of woody vegetation and to conserve a species-rich, open landscape.
