International Journal of Chemical Kinetics, EarlyView.ABSTRACT In the interstellar medium, chemical reactions proceed under conditions vastly different to those on Earth; these include extremely low temperatures and densities and take place in the gas phase and on water–ice grains. Understanding the energetics and more importantly the kinetics of such reactions is of relevance to the consequences on how ...

International Journal of Chemical Kinetics, EarlyView.ABSTRACT We present chemical kinetic rate constants for the cis to trans isomerisation or rotamerization of monomeric seleno‐, thio‐, and formic acids and that of three of their dimeric species, based on variational transition state theory and multidimensional tunneling calculations in the gas‐phase, from 10 K to 300 K. These provide, firstly, reliable

Heavy‐Metal‐Free Colloidal Quantum Dots for Photocatalysis
Small, EarlyView.Heavy‐metal‐free colloidal quantum dots provide sustainable photocatalytic platforms by combining tunable band structures, strong light absorption, and programmable surfaces/interfaces. This Review highlights how core/shell engineering, alloying, defect regulation, ligand design, and hybrid‐interface construction direct charge separation and ...

Small, EarlyView.In the context of phase heterostructures on two‐dimensional materials, a high‐precision direct writing approach is employed. This involves using a focused ion beam to transform molybdenum disulfide to the metallic 1T phase, followed by retransformation via ultrashort pulse laser processing.

Halogen‐Mediated Polymer‐Free Recovery of Pristine MoS2 Monolayers From Gold‐Assisted Exfoliation
Small Methods, EarlyView.Schematic procedure for halogen‐mediated polymer‐free recovery of pristine MoS2 monolayers from gold‐assisted exfoliation. ABSTRACT Metal‐assisted mechanical exfoliation has recently emerged as a powerful strategy for producing large‐area monolayers of two‐dimensional (2D) transition‐metal dichalcogenides (TMDs) with near‐intrinsic crystalline quality.

A Crystalline and Thermally Stable Selenocysteine Selenenic Acid
Angewandte Chemie, Volume 138, Issue 32, 3 August 2026.The long‐sought catalytic intermediate of selenoproteins, selenocysteine selenenic acid (Sec–SeOH), is isolated for the first time at ambient temperature. A bioinspired selenopeptide sequence encapsulated within a protective molecular cradle and an oxidant‐free route from selenenyl iodide (Sec–SeI) enable the isolation of Sec–SeOH. Contrary to the long‐
