Modularity and chemical flexibility of polyester urethanes (PEU) enable the combination of segments bearing functionalizable moieties and the tailoring of the mechanical and thermal properties. In this work, a PEU multiblock structure was synthesized from naturally derived L-lysine diisocyanate ethyl ester (LDI), poly(L-lactide) diol (PLLA) and N-(2,3-dihydroxypropyl)-maleimide (MID) in a one-step reaction. A maleimide side-chain (MID) provided a reactive site for the catalyst-free coupling of thiols shown for L-cysteine with a yield of 94\%. Physical cross-links were generated by blending the PEU with poly(D-lactide) (PDLA), upon which the PLLA segments of the PEU and the PDLA formed stereocomplexes. Stereocomplexation occurred spontaneously during solution casting and was investigated with WAXS and DSC. Stereocomplex crystallites were observed in the blends, while isotactic PLA crystallization was not observed. The presented material platform with tailorable mechanical properties by blending is of specific interest for engineering biointerfaces of implants or carrier systems for bioactive molecules.}, language = {en} } @article{IzraylitHommesSchattmannNeffeetal.2020, author = {Izraylit, Victor and Hommes-Schattmann, Paul Jacob and Neffe, Axel T. and Gould, Oliver E.

Here, we report an approach to incorporate reactive alkynyl side-groups by synthesizing a chain-extended PCL, where the reactive site is introduced through the covalently functionalizable chain extender 3 (prop-2-yn-1-yloxy)propane-1,2-diol (YPD). Chain-extended PCL with M-w of 101 to 385 kg.mol(-1) were successfully synthesized in a one-pot reaction from PCL-diols with various molar masses, L-lysine ethyl ester diisocyanate (LDI) or trimethyl(hexamethylene)diisocyanate (TMDI), and YPD, in which the density of functionalizable groups and spacing between them can be controlled by the composition of the polymer. The employed diisocyanate compounds and YPD possess an asymmetric structure and form a non-crystallizable segment leaving the PCL crystallites to dominate the material's mechanical properties. The mixed glass transition temperature T-g = - 60 to - 46 degrees C of the PCL/polyurethane amorphous phase maintains the synthesized materials in a highly elastic state at ambient and physiological conditions. Reaction conditions for covalent attachment in copper(I)-catalyzed azide-alkyne-cycloaddition reactions (CuAAC) in solution were optimized in a series of model reactions between the alkyne moieties of the chain-extended PCL and benzyl azide, reaching conversions over 95\% of the alkyne moieties and with yields of up to 94\% for the purified functionalized PCL. This methodology was applied for reaction with the azide-functionalized cell adhesion peptide GRGDS. The required modification of the peptide provides selectivity in the coupling reactions. The obtained results suggest that YPD could potentially be employed as versatile molecular unit for the creation of a variety of functionalizable polyesters as well as polyurethanes and polycarbonates offering efficient and selective click-reactions.}, language = {en} } @article{FontanaHeinzeLangeetal.2020, author = {Fontana, Sina and Heinze, Alexander and Lange, Pia and Th{\"o}ne, Meik}, title = {Editorial}, series = {Zeitschrift f{\"u}r das gesamte Verfahrensrecht}, volume = {3}, journal = {Zeitschrift f{\"u}r das gesamte Verfahrensrecht}, number = {1}, publisher = {Otto Schmidt}, address = {K{\"o}ln}, issn = {2625-1868}, doi = {10.9785/gvrz-2020-030101}, year = {2020}, language = {de} } @article{Thoene2020, author = {Th{\"o}ne, Meik}, title = {Von (Un-)Freiwilligkeit und (Un-)Parteilichkeit in der Sportschiedsgerichtsbarkeit}, series = {SchiedsVZ}, volume = {18}, journal = {SchiedsVZ}, number = {4}, publisher = {Beck}, address = {M{\"u}nchen}, issn = {1610-322X}, pages = {176 -- 182}, year = {2020}, abstract = {Mit der bevorstehenden Entscheidung des Bundesverfassungsgerichts in der Sache Pechstein neigt sich eine scheinbar endlose Geschichte dem Ende entgegen.

Consequentially, sociological reflection has tried to conceptualise ongoing processes of transforming the city under the concept of urban neo-liberalism which is generally understood as the contextually specific and path-dependent realisation of neo-liberal restructuration projects, embedded in varying social, political, economic, and cultural 'regulatory landscapes'. As much as neo-liberalism as ideology and political programme aims at erasing any democratic participation in society, its proponents have taken sides pushing ahead the re-conceptualisation of the city as a market with the right of the stronger 'to do down the weaker'. The city has become a focal point for neo-liberalism's war against democracy and citizens. Turning social relations into market transactions in order to restructure cities is not a new idea from the neo-liberals but one of the non-negotiable dogmas of their religion called science.}, language = {en} } @article{PutraPradhanKropp2020, author = {Putra, Muhammad Panji Islam Fajar and Pradhan, Prajal and Kropp, J{\"u}rgen}, title = {A systematic analysis of Water-Energy-Food security nexus}, series = {The science of the total environment : an international journal for scientific research into the environment and its relationship with man}, volume = {728}, journal = {The science of the total environment : an international journal for scientific research into the environment and its relationship with man}, publisher = {Elsevier}, address = {Amsterdam}, issn = {0048-9697}, doi = {10.1016/j.scitotenv.2020.138451}, pages = {9}, year = {2020}, abstract = {Most South Asian countries have challenges in ensuring water, energy, and food (WEF) security, which are often interacting positively or negatively. To address these challenges, the nexus approach provides a framework to identify the interactions of the WEF sectors as an integrated system. However, most nexus studies only qualitatively discuss the interactions between these sectors. This study conducts a systematic analysis of the WEF security nexus in South Asia by using open data sources at the country scale. We analyze interactions between the WEF sectors statistically, defining positive and negative correlations between the WEF security indicators as synergies and trade-offs, respectively. By creating networks of the synergies and trade-offs, we further identify most positively and negatively influencing indicators in the WEF security nexus. We observe a larger share of trade-offs than synergies within the water and energy sectors and a larger share of synergies than trade-offs among the WEF sectors for South Asia. However, these observations vary across the South Asian countries. Our analysis highlights that strategies on promoting sustainable energy and discouraging fossil fuel use could have overall positive effects on the WEF security nexus in the countries. This study provides evidence for considering the WEF security nexus as an integrated system rather than just a combination of three different sectors or securities.}, language = {en} }
