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.Nitrogen–boron–nitrogen (NBN)‐substituted molecular propellers are presented as structural framework for aggregation induced emission (AIE) applications. Steric hindrance is revealed to steer maximum‐AIE behavior, leading to refined control over assembly‐induced luminescence.

Torsional actuation and vari-stiffness characteristics of SMA/basalt hybrid braided composite tubes
Smart materials and structures (Print)Shape memory alloy hybrid composite (SMAHC) tubes have the potential to actively control the torsional stiffness of structures. In this work, shape memory alloy (SMA) wires orthogonally braided with basalt fiber were heated by electricity to generate the

Chemistry – A European Journal, EarlyView.Staggered, square, and heavily bent dimers occur in the five known solvatomorphs of paddlewheel (PW) complex [PtVO(SOCPh)4]. These and other structural motifs are well within energetic reach due to the shallow potential energy surface that guides dimerization and are included in a revised classification of available structural data on heterobimetallic ...

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.

Sustainable Energy Technologies and AssessmentsAbstract As wind turbines become larger and move into deeper sea, their operating environment is getting more and more harsh, which puts higher stability requirements of the transmission chain. The mechanical-hydraulic hybrid transmission (MHHT) combines mechanical and hydraulic systems to improve transmission stability.
