Study on the Reaction Mechanism of RuOx and Its Enhanced Hydrogen Evolution Reaction Activity
Advanced Science, EarlyView.In situ Raman spectroscopy and DFT calculations reveal that, prior to the onset of HER, the surface of RuOx undergoes reversible reduction and structural reconstruction. The resulting Ru(II)O/Ru(IV)O2 configuration is identified as the true catalytically active species.

On the problems of diffraction of electromagnetic waves by prefractal periodic gratings
Учёные записки Казанского университета: Серия Физико-математические наукиThis article examines the problems of diffraction of electromagnetic waves by periodic gratings composed of thin conductive strips (2D) or plates (3D) in cases where the strips and plates are prefractal sets.

Structural Colors from Modulated Topological Defects in Molecular Smectic Liquid Crystals
Advanced Science, EarlyView.Rather than using dyes and pigments, nature produces the colors of some butterflies and beetles through optical interference phenomena. This study describes an original biomimetic strategy exploiting the spontaneous formation of modulated linear defects in thin films of 8CB, a common molecular liquid crystal.

Advanced Science, EarlyView.Green and scalable synthesis of CsPbBr3 perovskite quantum dots using bio‐sourced lecithin and hexane enables single‐batch production over 10 grams. Suppressed Auger recombination and electron‐phonon coupling yields 95% PLQY, enhanced stability, and low ASE thresholds of 230.4 (ns) and 50.1 (fs) µJ cm−2 in neat films. ABSTRACT Halide perovskite quantum
