Bismuth Chalcogenide‐Based Photocatalysts for Nitrogen Reduction: Recent Progress and Prospects

Chemistry – A European Journal, EarlyView.
Bismuth chalcogenides emerge as promising visible‐light photocatalysts for sustainable ammonia synthesis, driven by tunable electronic structures and strong N2 activation. Recent advances reveal how defects, doping and heterojunction design synergistically enhance charge separation and reactivity. Key challenges and future directions highlight pathways

Hydrogen Release From Silicon─Hydrogen Systems: From Surface Chemistry to Higher‐Coordinate Molecular Mechanisms

Chemistry – A European Journal, EarlyView.
Hydrogen‐release processes in silicon chemistry occur across a broad spectrum of systems, including crystalline silicon surfaces, nanoporous materials, Zintl phases, and molecular hydrides. This Review highlights how Si─H activation and H2 evolution are governed by structure, coordination environment, and dynamic access to reactive geometries, with ...

Large Magnetocaloric Effect in a Ferromagnetically Coupled [Mn3Gd] Complex With a Spin Ground State of S = 11

Chemistry – A European Journal, EarlyView.
Systematic studies of a series of new 3d–4f tetranuclear complexes revealed that the ferromagnetically coupled [Mn3Gd] complex exhibits large magnetic entropy changes, especially at higher temperatures and under lower magnetic fields. ABSTRACT A series of 3d‐4f heterometallic tetranuclear complexes, (TEA)[Mn3Gd(L)3(NO3)4(CH3CN)2] ([Mn3Gd]), (TEA)[Mn3La(

The effect of preloading on the liquefaction cyclic strength of mixtures of sand and silt

, 2015
International audienceThe paper studies the effect of preloading on the liquefaction cyclic strength of silty sands in the free field condition. This effect first is investigated by cyclic shear tests where horizontal shear stress oscillated about a zero

Methanol With Increased Water Content in Internal Combustion Engines

Chemie Ingenieur Technik, EarlyView.
This study investigates the potential to improve overall Well‐to‐Wheel efficiency by using low‐purity methanol from synthesis of hydrogen and furnace gas as CO2‐source. Combustion efficiency is comparable to pure methanol, while distillation energy could be saved.
