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

Reversible Assembly and Disassembly of σ‐Aromatic B3 Rings

Chemistry – A European Journal, EarlyView.
B3 rings are the smallest σ‐aromatic boron compounds. Here, we show for the first time that cationic diboranes with an electron‐precise (2c,2e) bond can be reversibly converted to σ‐aromatic B3 rings with electron‐deficient (3c,2e) bonding. Base‐induced disassembly of the B3 ring leads back to cationic diboranes and monoborane adducts.

Consistent Techno‐Economic and Environmental Assessment of Hydrogen Production via Electrolysis

Chemie Ingenieur Technik, EarlyView.
This study performs a techno‐economic and life‐cycle analysis of hydrogen production via electrolysis under five electricity supply scenarios, including flexible operation with a baseload. Results highlight trade‐offs between cost and carbon intensity, exhibiting economic and ecological inefficiency of grid supportive electrolysis in Germany.

Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...

Critical expansion points: Mechanical signs of surrounding rock instability

Deep Underground Science and Engineering, EarlyView.
This study proposes the Rock Bearing‐Expansion Model (RockBEM) with critical expansion points (CEPs) to quantify post‐peak damage stages in deep‐buried rock masses via plane strain compression test (PSCT). CEP hysteresis&interval ratios reveal bearing performance dynamics and failure severity, advancing mechanistic insights into deep underground rock ...
