Overcrowded Alkene Photo‐Redox‐Switches Based on Quinolinium/Carbene Building Blocks
Angewandte Chemie International Edition, EarlyView.A modular synthesis of a new class of photo‐ and redox‐switches is described based on the combination of quinolinium salts and carbenes. Photochemical switching allows to selectively switch between folded E/Z isomers, while electrochemical switching allows to change between neutral, radical cation and dicationic oxidation states, which are all isolable

MAGNETORHEOLOGICAL ELASTOMER-BASED FLEXIBLE COUPLING FOR TORSIONAL VIBRATION ISOLATION
, 2022 Employing vibration isolation can avoid the detrimental effects of unattenuated torsional vibrations on rotary mechanical equipment. Semi-active vibration isolators can effectively reduce the vibration levels in mechanical systems.

Surface Charges Guided Quasi‐TEM‐mode Microwave Propagation along Dielectric Nanowire
Advanced Physics Research, EarlyView.According to Maxwell's equations, a single‐conductor transmission line cannot allow TEM‐mode electromagnetic wave propagation, however, this is based upon the assumption that dielectric material is isolated from the environment. In practice, surface electrostatic charges widely existed in nano‐materials with large surface‐to‐volume ratio.

Chemistry – A European Journal, EarlyView.Copper(I) hydride complexes often exhibit diverse aggregation behavior that can profoundly influence their structure and reactivity. In this study we use a combined experimental and computational approach to identify key structural an electronic factors that govern aggregation in PNNP dicopperhydride complexes.

Chemistry – A European Journal, EarlyView.Open halogen‐bonded networks have been prepared from building blocks that incorporate both iodoalkyne halogen bond donors and a pyridine‐N‐oxide halogen bond acceptor. An initially‐formed 3D network containing dioxane in its channels undergoes an unprecedented transition to a 2D material when crystals are exposed to diethyl ether.

N─H or O─H Bond Activation With a Bicyclic Si4 Ring Compound
Chemistry – A European Journal, EarlyView.The bicyclic Si4 ring compound with zwitterionic character reacts with NH3, H2O, and selected alcohols to give functionalized saturated silicon rings, siliconoid clusters with unsubstituted Si atoms, or simple 1,3‐addition products. The experimentally observed reactivity could be rationalized based on results from mechanistic calculations employing ...

Energy Landscapes in Chemical Reactions and Transport
ChemPhysChem, Volume 26, Issue 6, March 15, 2025.Kinetics/dynamics of chemical reactivity and transport of chemical species in a solid are both determined by the energy landscape in which they take place. Discussing common grounds but also distinct differences may help in advancing the understanding in both fields.
