Gold Single‐Atom Catalysts Enable Selective Shuttle Hydrochlorination of Alkynes
Angewandte Chemie International Edition, EarlyView.Gold single‐atom catalysts on activated carbon enable heterogeneous shuttle hydrochlorination of terminal alkynes to vinyl chlorides with high chemo‐ and stereo‐selectivity thanks to cooperation between Au(I) sites and the support. The catalytic system combines broad substrate compatibility, simplified separation, and recoverability, paving the way for

Deuterium-Free, Three-Plexed Peptide Diethylation for Highly Accurate Quantitative Proteomics
, 2019 The deuterium, a frequently used stable isotope in isotopic labeling for quantitative proteomics, could deteriorate the accuracy and precision of proteome quantification owing to the retention time shift of deuterated peptides from the hydrogenated ...

Unraveling the Importance of Surface Hydrogen Diffusion in Photocatalysis by Isotope Probing
Angewandte Chemie International Edition, EarlyView.Surface hydrogen diffusion on titanium dioxide is identified as a crucial step in photocatalytic hydrogen evolution. Demonstrated by deuterium substitution in methanol, restricted diffusion to the co‐catalyst leads to hindered formation of molecular hydrogen and a high KIE.

Fluids under High Pressure Insighted by Operando Neutron Imaging and Molecular Dynamics Simulations
Advanced Physics Research, EarlyView.There is limited research on how fluids behave under the extreme conditions found in fuel gas systems (high pressure) and catalytic reactors (high temperature and pressure). Neutron Imaging provides experimental data on interfacial tension, and Henry's law volatility constant, apparent molar volume, and diffusion coefficient for systems from toluene ...

“Dead Lithium” Formation and Mitigation Strategies in Anode‐Free Li‐Metal Batteries
Batteries &Supercaps, Volume 8, Issue 3, March 2025.Anode‐free lithium metal batteries, though promising due to their high energy density, face challenges from dead lithium formation. “Dead lithium”, disconnected from the anode, causes capacity loss, increased resistance, and safety risks. This review explores the origins of dead lithium, its impact on battery performance, and potential strategies for ...
