Angewandte Chemie, EarlyView.O2 verbessert den Ladungstransfer in organischen n‐Typ‐Donor‐Akzeptor‐Ladungstransferkomplexen (CTCs) durch physisorptive Passivierung von Ladungsträgerfallen. Durch die Unterdrückung der Rekombination und die Förderung langlebiger delokalisierter Ladungsträger verbessert O2 den Elektronentransport und die Leitfähigkeit ohne Dotierung.

An analysis of the NEXAFS spectra of a molecular crystal: α-glycine [PDF]
The Journal of Chemical Physics, 2010 The nitrogen K-edge near edge x-ray absorption fine structure spectrum of α-crystalline glycine has been calculated for temperatures ranging from 0 to 450 K. Significant temperature dependent spectral changes are predicted. The calculated room temperature spectrum is in good agreement with the experiment.

Role of Water in Low‐Temperature CO2 Reduction at Defect‐Rich TiO2
Angewandte Chemie International Edition, EarlyView.Our results highlight the potential of reduced titania as a noble metal‐free CO2 activation catalyst and show the activation of CO2 on highly defective TiO2 using in situ synchrotron‐based NAP‐XPS from room temperature to 700 K. The distribution of surface intermediates can be decoded as a simultaneous population of reaction routes, revealing water (OH)

Angewandte Chemie International Edition, EarlyView.O2 enhances charge‐transfer in n‐type organic donor–acceptor charge‐transfer complexes (CTCs) via physisorption‐mediated trap passivation. By suppressing recombination and promoting long‐lived delocalized charge carriers, O2 improves electron transport and conductivity without doping.

Angle Resolved NEXAFS Spectra of Hexagonal and Cubic GaN
, 1997 Phase stabilised cubic and hexagonal GaN thin films, grown by MBE, are studied using angle (φ) resolved NEXAFS measurements at the N-K-edge. It is demonstrated that the energy positions and intensities of the characteristic NEXAFS resonances depend on ...
