Ultrathin chemosensors based on molecularly imprinted polymerization enable a realization of another capacitive approach that exploits changes in electrical capacitance due to modification of the dielectric constant of the polymer. Such chemosensors were prepared by photografted molecularly imprinted polymerization on the surface of gold electrodes. An adsorbed layer of hydrophobic photoinitiator (benzophenone) provided grafted polymerization on the surface of the alkanethiol-modified gold electrode. The chemosensors were characterized by cyclic voltammetry, impedance spectroscopy, and scanning electron and atomic force microscopy. Binding of analyte was detected by measurements of electrical capacitance. The results indicate a decrease of the dielectric constant of the polymer layer due to analyte binding up to 20\%.}, language = {en} } @inproceedings{JankeGollerMartinetal., author = {Janke, Christian and Goller, M. and Martin, Ivo and Gaun, Lilia and Bestle, Dieter}, title = {3D-CFD Compressor Map Computation of a Multi-Stage Axial Compressor with Off-Design Adjusted Rotor Geometries}, series = {ASME Turbo Expo 2016, Turbomachinery Technical Conference and Exposition, Volume 7A, Structures and Dynamics, Seoul, South Korea, June 13-17, 2016}, booktitle = {ASME Turbo Expo 2016, Turbomachinery Technical Conference and Exposition, Volume 7A, Structures and Dynamics, Seoul, South Korea, June 13-17, 2016}, publisher = {ASME}, address = {New York, NY [u.a.]}, isbn = {978-0-7918-4983-5}, language = {en} } @misc{HirschZharnikovShaporenkoetal., author = {Hirsch, Thomas and Zharnikov, Michael and Shaporenko, Andrey and Stahl, Joachim and Weiss, Dieter and Wolfbeis, Otto S. and Mirsky, Vladimir M.}, title = {Size-controlled electrochemical synthesis of metallic nanoparticles on molecular templates}, series = {Angewandte Chemie International Edition}, volume = {44}, journal = {Angewandte Chemie International Edition}, number = {41}, issn = {1521-3773}, doi = {10.1002/anie.200500912}, pages = {6775 -- 6778}, abstract = {Reduction on the spot: Planarly adsorbed thiolated porphyrin molecules (purple) incorporated in an insulating alkanethiol monolayer (blue) function as nanoelectrodes for the local reduction of metals (gray).
