High electromagnetic field enhancement of TiO2 nanotubes electrodes

Inez Weidinger and coworkers have published a joint paper of three Unicat groups in Angewandte Chemie. They have created nanotubular TiO2 electrodes with unpreceded local light enhancement within the tubes. These nano-electrodes can be used for enhancing photocatalytic processes at the TiO2 interface and for surface enhanced spectroscopy.

Efficient Light-Induced pKa-Modulation coupled to Base-Catalyzed Photochromism

Hot Paper of Stefan Hecht and coworkers in Angewandte Chemie. Photoswitchable acid-base pairs, whose pKa values can be reversibly altered, are attractive molecular tools to control chemical and biological processes with light. We could now realize a significant, light-induced pKa change of three units in aqueous medium between two thermally stable states, which can be interconverted using UV and green light.

New joint paper on hydrogenase

Tracking the route of substrates, intermediates, and inhibitors in proteins is fundamental in understanding their specific function. However, following the route of gases like molecular oxygen within enzymes has always been challenging. In protein X-ray crystallography, gases can be mimicked using krypton or xenon (with a higher electron count); however, these have a different physical behavior compared to true substrates/inhibitors. In our crystal structure of the O2-tolerant membrane-bound [NiFe] hydrogenase (MBH) from Ralstonia eutropha, we...[more]
