Enhanced Hydrogen Evolution on Ru‐Modified Cu1.8Se/Cu2Se Catalysts in Alkaline Media

Israel Journal of Chemistry, Volume 66, Issue 4, July 2026.
We synthesized Ru‐modified Cu1.8Se/Cu2Se electrocatalysts using solvothermal–annealing for alkaline hydrogen evolution reaction. A minimal 2.1 wt% Ru catalyst exhibited a low overpotential of 169 mV at 10 mA cm−2 with excellent stability, approaching the performance of Pt/C.

Silver‐Alloyed Wide‐Bandgap (Ag,Cu)(In,Ga)S2 Thin‐Film Solar Cells With 15.5% Efficiency

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 7, Page 942-956, July 2026.
This study reports improvements in compositional homogeneity, microstructure, enhanced radiative recombination, and extended carrier lifetime of CIGS absorber via Ag incorporation. The optimal Ag‐alloyed CIGS solar cells achieve 15.5% PCE and 948 mV VOC, competing with the VOC of the Ag‐free reference sample from the same batch.

Breaking Shuttle‐Induced Kinetics Limitations in Lithium–Sulfur Batteries: Confined FeS2 Nanocatalyst With Optimized d‐Band Center

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT The commercialization of lithium‐sulfur batteries (LSBs) faces dual challenges of sluggish sulfur redox kinetics and lithium polysulfides (LiPSs) shuttling. Herein, we demonstrate a synergistic strategy combining multidimensional structural confinement with d‐band center modulation to simultaneously suppress LiPSs diffusion and catalyze ...

A Generalized Automated Framework for Thermal Characterization: From Bulk Materials to Complex Heterostructures

Small, Volume 22, Issue 37, 2 July 2026.
An automated MATLAB framework for inverse photoacoustic analysis enables precise thermal characterization of complex multilayer films. Application to electrodeposited CuxSe reveals a stoichiometry‐dependent thermal conductivity governed by lattice anharmonicity, not grain‐size scattering, in these superionic materials. ABSTRACT Precise determination of

Thermal and Photocatalytic Conversion of CO2 to Ethanol: Advances in Catalyst Design, Challenges, and Opportunities

ChemSusChem, Volume 19, Issue 12, 26 June 2026.
This review examines thermo‐ and photocatalytic routes for converting CO2 to ethanol and analyzes how metal alloying, promoters, supports, surface structure, and semiconductor design govern catalyst activity, selectivity, and stability. It integrates mechanistic insights from experimental and theoretical studies and identifies the main challenges and ...
