Global Challenges, Volume 10, Issue 9, September 2026.A chromium‐substituted monovacant Keggin polyanion was immobilized on the surface of graphene oxide. The obtained nanocatalyst showed high catalytic activity in the reduction of various nitroarenes under mild conditions. GC‐MS analysis confirmed the direct pathway for reduction of nitroarenes in the presence of the catalyst.

Siral‐HPW‐Supported Pd and Ru Catalysts Evaluation for Glycerol Upgrading
ChemistrySelect, Volume 11, Issue 35, 15 September 2026.MSiralHPW (M = Ru, Pd, and PdRu) catalysts are active in glycerol hydrogenolysis. Metal (Ru > Pd) and precursor (Cl− > NO3−) influences were verified. Promoting effect of RuO2 reduction by Pd did not influence the metallic dispersion. Residual chlorine promoted acidic sites suitable for the formation of 1,3‐PDO.

Real‐Time Investigation of Interfacial Evolution in Electrochemical Energy Storage Systems via EQCM
Advanced Science, Volume 13, Issue 46, 17 August 2026.Understanding the electrode/electrolyte interface (EEI) is crucial for supercapacitors and batteries. EQCM, by enabling real‐time monitoring of mass changes during charge–discharge cycles, has evolved into a vital method for analysis of EEI. It provides important insights into charge‐storage mechanisms, electrode structural evolution, ion‐transfer ...
