@article{35645, abstract = {{Poly(quinuclidin-3-yl methacrylate-co-divinylbenzene) microparticles having porous as well as nonporous morphology and varying contents of quinuclidine functionality were synthesized by distillation–precipitation polymerization. Further, the synthesized microparticles were explored to catalyze the Baylis–Hillman reaction between 4-nitrobenzaldehyde and acrylonitrile. Porous and nonporous microparticles functionalized with a catalytic moiety with a loading of 70% (labeled as P70 and NP70) were employed to optimize reaction parameters such as water content, solvent, and temperature for the Baylis–Hillman reaction between 4-nitrobenzaldehyde and acrylonitrile. Using optimal conditions, the catalytic efficiency of porous and nonporous microparticles at different feed compositions was determined. Porous microparticles containing 70% of quinuclidine (P70) displayed 100% conversion within 16 h at 50 °C, while nonporous microparticles containing 70% of quinuclidine (NP70) displayed a relatively less catalytic conversion, which is attributed to their lower surface area. Furthermore, the catalytic activity of porous microparticles containing 70% of quinuclidine (P70) for the Baylis–Hillman reaction involving a variety of aryl aldehyde derivatives was determined, where the microparticles displayed impressive catalytic efficiency. In addition, the reusability of the microparticles functionalized with a catalytic moiety was evaluated for five cycles of catalytic reaction.}}, author = {{Kumar, Amit and Kuckling, Dirk and Nebhani, Leena}}, issn = {{2637-6105}}, journal = {{ACS Applied Polymer Materials}}, keywords = {{distillation−precipitation polymerization, porous microparticles, heterogeneous catalysis Baylis−Hillman reaction, reusable catalyst}}, number = {{12}}, pages = {{8996--9005}}, publisher = {{American Chemical Society (ACS)}}, title = {{{Quinuclidine-Immobilized Porous Polymeric Microparticles as a Compelling Catalyst for the Baylis–Hillman Reaction}}}, doi = {{10.1021/acsapm.2c01330}}, volume = {{4}}, year = {{2022}}, } @article{32865, abstract = {{For the first time, poly(N-isopropylacrylamide) (PNIPAAm) star polymers with a β-cyclodextrin core are characterized in detail by size-exclusion chromatography (SEC) with triple detection to experimentally verify the number of arms. A combination of a refractive index detector, multi-angle laser light scattering detector, and an online-viscosimeter was used for branching analysis. At first, the SEC system was calibrated and the detector setup was validated using linear polystyrene reference polymers. The applicability of the established triple detection SEC for branching analysis was shown by the analysis of two commercially available polystyrene star polymers. Due to the high molar masses of the star polymers, both the contraction ratio g and g′ could be determined independently, thus allowing the calculation of the viscosity shielding ratio ε. Finally, the branching analysis of the PNIPAAm star polymers could experimentally confirm the assumed arm number of up to 21 arms. Moreover, an increasingly compact molecular structure and the influence of the arm number on the viscosity shielding ratio could be shown.}}, author = {{Herberg, Artjom and Kuckling, Dirk}}, issn = {{1023-666X}}, journal = {{International Journal of Polymer Analysis and Characterization}}, keywords = {{Size-exclusion chromatography, triple detection, branching analysis, star polymers, poly(N-isopropylacrylamide), β-cyclodextrin}}, pages = {{1--19}}, publisher = {{Informa UK Limited}}, title = {{{Branching analysis of β-cyclodextrin-based poly(N-isopropylacrylamide) star polymers using triple detection SEC}}}, doi = {{10.1080/1023666x.2022.2110133}}, year = {{2022}}, } @article{34056, abstract = {{ A process sequence enabling the large-area fabrication of nanopillar-patterned semiconductor templates for selective-area heteroepitaxy is developed. Herein, the nanopillar tops surrounded by a SiNx mask film serve as nanoscale growth areas. The molecular beam epitaxial growth of InAs on such patterned GaAs[Formula: see text]A templates is investigated by means of electron microscopy. It is found that defect-free nanoscale InAs islands grow selectively on the nanopillar tops at a substrate temperature of 425 °C. High-angle annular dark-field scanning transmission electron microscopy imaging reveals that for a growth temperature of 400 °C, the InAs islands show a tendency to form wurtzite phase arms extending along the lateral [Formula: see text] directions from the central zinc blende region of the islands. This is ascribed to a temporary self-catalyzed vapor–liquid–solid growth on [Formula: see text] B facets, which leads to a kinetically induced preference for the nucleation of the wurtzite phase driven by the local, instantaneous V/III ratio, and to a concomitant reduction of surface energy of the nanoscale diameter arms. }}, author = {{Riedl, Thomas and Kunnathully, Vinay S. and Verma, Akshay Kumar and Langer, Timo and Reuter, Dirk and Büker, Björn and Hütten, Andreas and Lindner, Jörg}}, issn = {{0021-8979}}, journal = {{Journal of Applied Physics}}, keywords = {{General Physics and Astronomy}}, number = {{18}}, publisher = {{AIP Publishing}}, title = {{{Selective area heteroepitaxy of InAs nanostructures on nanopillar-patterned GaAs(111)A}}}, doi = {{10.1063/5.0121559}}, volume = {{132}}, year = {{2022}}, } @article{34053, author = {{Riedl, Thomas and Kunnathully, Vinay and Trapp, Alexander and Langer, Timo and Reuter, Dirk and Lindner, Jörg}}, issn = {{2196-7350}}, journal = {{Advanced Materials Interfaces}}, keywords = {{Mechanical Engineering, Mechanics of Materials}}, number = {{11}}, publisher = {{Wiley}}, title = {{{Size‐Dependent Strain Relaxation in InAs Quantum Dots on Top of GaAs(111)A Nanopillars}}}, doi = {{10.1002/admi.202102159}}, volume = {{9}}, year = {{2022}}, } @article{34086, author = {{Bürger, Julius and Venugopal, Harikrishnan and Kool, Daniel and de los Arcos de Pedro, Maria Teresa and Gonzalez Orive, Alejandro and Grundmeier, Guido and Brassat, Katharina and Lindner, Jörg}}, issn = {{2196-7350}}, journal = {{Advanced Materials Interfaces}}, keywords = {{General Medicine}}, number = {{26}}, publisher = {{Wiley}}, title = {{{High‐Resolution Study of Changes in Morphology and Chemistry of Cylindrical PS‐ b ‐PMMA Block Copolymer Nanomasks during Mask Development}}}, doi = {{10.1002/admi.202200962}}, volume = {{9}}, year = {{2022}}, } @article{35987, author = {{Schlegel-Matthies, Kirsten}}, issn = {{2193-8806}}, journal = {{Haushalt in Bidlung und Forschung}}, number = {{1}}, pages = {{89--94}}, publisher = {{Barbara Budrich}}, title = {{{Zur Erinnerung: Warum Bildung für Lebensführung immer eine politische Dimension hat.
