ChemBioChem, Volume 27, Issue 14, 29 July 2026.5‐Keto‐4‐deoxy glucarate dehydratase and 2‐keto‐3‐deoxy‐L‐arabinonate dehydratase share many similarities like structure, reaction mechanism, and their generated product, but exhibit very high substrate specificity. Here, we explore the evolutionary development of this specificity in the context of the enzyme superfamily and attempt to find promiscuous

Advanced Synthesis &Catalysis, Volume 368, Issue 13, 2 July 2026.Combining dichloro and diiodo ruthenium catalysts produces mixed chloro–iodo species via in situ halide exchange, resulting in a new, more efficient catalytic system. The mixed catalysts outperform their homo‐anionic counterparts, delivering enhanced activity, higher conversion, and strong suppression of isomerization under both thermal and ...

Heat Capacity of Various (Solvent + Terpene) Mixtures as Function of Composition and Temperature
, 2023 The heat capacity of different mixtures of terpenes (α-pinene, β-pinene, limonene oxide) and solvents (acetone, toluene, ethyl acetate) at atmospheric pressure (85.1 kPa atm in Medellin, Colombia) were measured using a microcalorimeter at several terpene

ChemCatChem, Volume 18, Issue 14, 29 July 2026.This study demonstrates that nickel–platinum nanoparticles supported on biocompatible hydroxyapatite enable efficient reductive regeneration of nicotinamide adenine dinucleotide (NADH) using molecular hydrogen as a sustainable reductant. The bimetallic Ni–Pt system on nanocrystalline hydroxyapatite allows yields and selectivity in NAD+ reduction to be ...

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.This study examines the structural and chemical evolution of low‐loaded Ir/ATO anodes during PEM water electrolysis under realistic conditions. Iridium dissolution is largely suppressed. In the early stages, both ionomer and support degradation are detected. Morphological reorganization occurs at the interface between the anode catalyst layer (ACL) and
