M–O–C Catalysts: Copper Single Atoms Supported on Oxocarbon Covalent Networks as Electrocatalysts for Glycerol Oxidation to Formic Acid

open access: yesAngewandte Chemie, Volume 138, Issue 7, 9 February 2026.
We introduce a new class of single‐atom electrocatalysts based on oxygen‐coordinated metal sites embedded in oxocarbon networks (M–O–C), alternative to traditional M–N–C materials. A Cu–O–C catalyst derived from oxocarbon precursors exhibits highly dispersed Cu single atoms and delivers faster glycerol oxidation kinetics and higher formate selectivity ...

Effect of the Fe Content on the Oxide Film Composition and Corrosion Resistance of Inconel 625: An XPS and Cyclic Potentiodynamic Polarisation Study

open access: yesSurface and Interface Analysis, Volume 58, Issue 3, Page 151-163, March 2026.
ABSTRACT The present work focuses on investigating the effect of increasing Inconel 625 Fe content on the oxide film composition and corrosion behaviour through XPS and cyclic potentiodynamic polarisation (CPP) studies. Different proportions of ASTM A182 F22 steel and Inconel 625 were arc‐melted to achieve a range of Fe contents (2–15 wt.%) in the ...

Accession‐Specific Responses to Submergence Stress in Lotus japonicus: Implications for Legume Climate Resilience

open access: yesJournal of Agronomy and Crop Science, Volume 212, Issue 2, March 2026.
ABSTRACT Flooding is a major abiotic stress that limits legume productivity and ecological resilience. Identifying variation in submergence tolerance among legume accessions is critical for developing climate‐resilient cultivars. This study investigated phenotypic and physiological responses to complete submergence in nine Lotus japonicus accessions ...

Copper Catalyzed Anisotropic Dissolution of Silicon in HF–HCl Solutions: Metal‐Assisted Chemical Etching Without Additional Oxidant

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 5, 9 February 2026.
Metal‐assisted chemical etching without an oxidant? We report an unexpected Cu2+‐catalyzed anisotropic etching of silicon in HF–HCl solutions. Despite the low redox potential of Cu2+, pyramidal surface structures are generated without a distinctive additional oxidizing agent.
