Polyzwitterionic Organohydrogel and Soft Composite with Tunable Sol–Gel Properties Enabling On‐Demand Functionalization with Colloids

Advanced Science, Volume 13, Issue 12, 27 February 2026.
Poly[2‐(methacryloyloxy)ethyl]dimethyl‐(3‐sulfopropyl)ammonium hydroxide‐based organohydrogels are formed via nonsolvent‐induced gelation, featuring tunable viscoelasticity. Functional fillers (MXene nanosheets, magnetic NdFeB microparticles) enable electrical, magnetic, and mechanical responsiveness for applications in mechano‐tunable electromagnetic ...

Effect of Water on Electrochemical β‐Hydrocarboxylation of Vinylphenol Derivatives With CO2

Asian Journal of Organic Chemistry, Volume 15, Issue 2, February 2026.
Electrochemical hydrocarboxylation of vinylphenols with CO2 was accomplished under mild conditions in an undivided cell without the use of a sacrificial anode. Optimal conditions using tetraethylammonium p‐toluenesulfonate (Et4NOTs), water, and a low current density enabled the efficient synthesis of carboxylic acids from vinylphenol derivatives in the

Operando Spectroscopy and Kinetic Modelling Reveal Dynamic Catalyst Species During Auto‐Oxidation of a Palladium Phosphine System

ChemCatChem, Volume 18, Issue 3, 12 February 2026.
ABSTRACT Ligand oxidation is a reoccurring catalyst deactivation mechanism in catalytic systems containing phosphine ligands. Here we report the use of operando FTIR spectroscopy for the investigation of the aerobic oxidation of the common Pd‐triphenylphosphine catalytic system using [Pd(OAc)2] and [Pd(PPh3)4] as precursors.
