Stable Synapse‐Like Memory Switching in N‐Heterocyclic Carbene Monolayers

Angewandte Chemie, Volume 138, Issue 25, 15 June 2026.
We report a redox‐active N‐heterocyclic carbene (NHC) monolayer showing synapse‐like behavior via proton‐coupled electron transfer (PCET). These quinone‐functionalized NHCs form dense self‐assembled monolayers and highly stable molecular junctions. Bias‐driven PCET switches quinone/hydroquinone states, producing reversible hysteresis and spike‐timing ...

Ordered Nanostructural Engineering of Cathode Catalyst Layer With High Mass Transport Efficiency for High‐Performance Ultra‐Low Pt Loading Proton Exchange Membrane Fuel Cells

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
An ordered cathode catalyst layer with efficient mass transport capability was developed based on the ALD of Pt onto VACNTs for high‐performance ultra‐low Pt loading PEMFC. The order‐structured cathode catalyst layer (CCL) has been considered the most promising solution to construct low‐cost proton exchange membrane fuel cells (PEMFCs) with an ultra ...

A Proof of Principle for the Phase‐Dependent Electrocatalytic Activity of NiTi Shape Memory Alloys for the Oxygen Evolution Reaction

ChemElectroChem, Volume 13, Issue 12, 17 June 2026.
We compare martensitic (Ni50Ti50) and austenitic (Ni51.2Ti48.8) NiTi shape memory alloys at room temperature as oxygen evolution reaction (OER) anodes, demonstrating that phase‐dependent microstructure governs electronic conductivity, surface roughness, and wettability.

Redox‐Active Guanidines

ChemElectroChem, Volume 13, Issue 12, 17 June 2026.
Redox‐active guanidines, comprising guanidino‐functionalized aromatics (GFAs) and redox‐active urea azines (RAAs), are electron donors and strong Lewis and Brønsted bases that are used in several applications. They act as redox‐active ligands in bistable coordination compounds and as reagents in dehydrogenative coupling reactions and proton‐coupled ...

Rational Optimization of Self‐Reporting Alcohol‐Oxidizing RhIII$^{\mathrm{III}}$ Complexes

European Journal of Inorganic Chemistry, Volume 29, Issue 17, 17 June 2026.
A series of four different [(NN)Rh(Cp*)X]n+$^{\mathrm{n+}}$ complexes (NN = chelating α$\alpha$‐diimine ligand, Cp* = pentamethylcyclopentadienyl, X = Cl, solvent) are reported which all do possess a colorimetric self‐reporting property upon alcohol oxidation formation of the Rh(I) state. Analysis of alcohol oxidation rates
