Zur Rolle von Wasser bei der CO2‐Reduktion an defektreichem TiO2 bei niedrigen Temperaturen

Angewandte Chemie, EarlyView.
Unsere Ergebnisse unterstreichen das Potenzial von reduziertem Titandioxid als edelmetallfreiem Katalysator zur Aktivierung von CO2 und zeigen in situ die Reaktion von CO2 auf defektreichem TiO2 unter Verwendung von synchrotronbasiertem NAP‐XPS von Raumtemperatur bis 700 K.

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)

Glyoxylic‐Acetal‐Based Gel‐Polymer Electrolytes for Lithium‐Ion Batteries

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
A safe electrolyte based on tetraethoxyglyoxal (LE) is combined with a methacrylate polymer matrix. The resulting gel‐polymer electrolyte (GPE) exhibits an increased flash point, suitable ionic conductivity, and a stable performance in lithium‐ion battery cells.

Compensatory rearrangement of parvalbumin interneuron voltage‐gated sodium channel subunits in a mouse model of Dravet syndrome

Epilepsia, EarlyView.
Abstract Heterozygous loss‐of‐function variants in the gene SCN1A, which encodes the voltage‐gated sodium channel (VGSC) pore‐forming (α) subunit NaV1.1, lead to a spectrum of neurological disease, including Dravet syndrome. NaV1.1 is prominently expressed at the proximal portion of the axon initial segment (AIS) of fast‐spiking γ‐aminobutyric ...
