Ruthenium‐Titania Interface‐Mediated Water Activation for High Turnover Frequency in Alkaline Hydrogen Evolution

open access: yesCarbon Energy, EarlyView.
Heterostructured interfaces can accelerate hydrogen evolution by improving water dissociation, yet their underlying mechanisms remain unclear. This study combines in situ Raman spectroscopy and density functional theory to reveal how the RuO2/TiO2 interface promotes both water dissociation and hydrogen adsorption, providing new insights into the ...

Boosting Sodium Storage Activity and Kinetics of Hard Carbon by Remodeling Oxygen Chemistry

open access: yesCarbon Energy, EarlyView.
A surface oxygen remodeling strategy is proposed to finely furnish the pseudographitic structure of hard carbon with rich closed pores and expanded interlayer spacings. Accordingly, the sodiation reactivity and kinetics are greatly reinforced to afford an elevated capacity of 360 mAh g−1 and outstanding rate capability of 225 mAh g−1 at 2 A g−1 ...

The Stabilization of High‐Nitrogen Systems: 10 Catenated Nitrogen Chain

open access: yesChemistry – A European Journal, EarlyView.
Improving the understanding of high‐nitrogen materials. ABSTRACT High‐nitrogen materials have attracted intense interest in recent decades due to their unique chemical, physical, and biological properties. Stabilizing high‐nitrogen materials is often challenging as they become more unstable with increasing nitrogen catenation and nitrogen mass ...

Synthetic Strategies for Activity‐Based Probes to Decode Ubiquitin‐Like Modifiers

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT Ubiquitin‐like proteins (Ubls) such as SUMO, NEDD8, ISG15, URM1, UFM1, FAT10, ATG8/ATG12, and FUBI are essential regulators of cellular homeostasis, controlling processes from protein stability and trafficking to immune signaling and autophagy.

Catalyst‐Free Cyanation of Arenes by Acetonitrile in a Plasma–Liquid Microreactor

open access: yesChemistry – A European Journal, EarlyView.
An original approach of arylnitrile synthesis was developed by generating an argon plasma in contact with solutions of arene in acetonitrile within a gas‐liquid microreactor. Plasma activation of acetonitrile generated cyano radicals, enabling a catalyst‐free C‐H cyanation of arenes.
