Gold Nanoparticles Supported on Poly(Phenylene Oxide) as Selective and Versatile Catalyst for Hydroamination of Arylacetylenes with Anilines

European Journal of Inorganic Chemistry, Volume 29, Issue 19, 2 July 2026.
Gold nanoparticles supported on poly(2,6‐dimethyl‐1,4‐phenylene oxide) (AuNPs‐PPO) demonstrates efficient and selective hydroamination, with performance tuned by reaction conditions and substrate design. Electron‐withdrawing substituents enhance conversion while preserving E‐imine selectivity, highlighting a key role of intermediate acidity.

Leaf‐Inspired Eutectic Skin With Extreme Fatigue Resistance and Robust Wet Adhesion for Amphibious Epidermal Electronics

Advanced Materials, Volume 38, Issue 37, 2 July 2026.
Inspired by Acorus calamus leaves, a heterogeneous eutectic skin integrates an aligned fibrous network within a hydrophobic eutectogel matrix. This hierarchical architecture triggers strain‐induced crystallization to achieve exceptional mechanical toughness and durable wet adhesion.

Machine Learning Accelerates Crystallization for Structure Determination

Angewandte Chemie, Volume 138, Issue 25, 15 June 2026.
Single‐crystal X‐ray diffraction (SCXRD) is often constrained by the difficulty of obtaining suitable crystals. Here, a machine learning‐accelerated co‐crystal discovery workflow is established for a crystalline mate strategy that achieves over 95% prediction accuracy and experimentally delivers 114 co‐crystals from 120 candidates.

Chiral (Stereoselective) Drugs, Asymmetric Synthesis, and Racemic Resolution Methods

Chirality, Volume 38, Issue 7, July 2026.
Chirality is crucial in drug development since both biological targets in the organism and the majority of pharmaceutical compounds are chiral. The synthesis and resolution of chiral compounds are critical steps while developing chiral drugs. Asymmetric synthesis and racemic resolution are the two most common methods for obtaining enantiopure drugs ...

Hierarchically Porous Coatings for Cellulose Fibers by Core–Shell Particle Templating

Macromolecular Rapid Communications, Volume 47, Issue 13, 3 July 2026.
Hybrid and functional core–shell particles comprising a silica core and a polymer shell were synthesized and used to develop a coating and etching process applied to a cellulose substrate. This resulted in highly porous, functional coatings on a cellulose membrane for further application in cellulose‐based adsorbers and advanced membrane technology ...

An Electron‐Poor Nickel Diphosphine Complex: Synthesis, Structure, and Reactivity of Ni(dFppe)2

Chemistry – A European Journal, Volume 32, Issue 24, 23 June 2026.
Fluorinated diphosphine ligands such as 1,2‐bis[bis(pentafluorophenyl)phosphino]ethane (dFppe) offer powerful electronic tunability and unusual reactivity. Despite known analogues of the heavier congeners Pd and Pt, Ni complexes of dFppe remain conspicuously absent.
