Surface‐driven size scaling of the lattice parameter, Debye–Waller coefficient and microstrain in nanocrystals

Acta Crystallographica Section A, EarlyView.
This work develops three surface‐driven nanoscale models for the diffraction‐derived lattice parameter, Debye–Waller coefficient and microstrain, clarifying why their size dependences are not equally universal. Atomistic simulations and literature data show that lattice parameter trends depend strongly on capillarity, chemistry and defects, whereas the

A New Paradigm for Understanding the Rheology and Processability of Poly(p‐Phenylene Terephthalamide) Liquid‐Crystalline Solutions

Journal of Applied Polymer Science, Volume 143, Issue 34, September 10, 2026.
Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics

Charge‐Decoupled Functional Switching in 2D/3D Integrated Heterostructure Electrodes for Dual‐Mode Electrochemical and Photoelectrochemical Hydrogen Production

EcoMat, Volume 8, Issue 9, September 2026.
A charge‐decoupled 2D/3D integrated electrode is presented for water‐to‐hydrogen conversion relevant to carbon‐neutral energy systems. An n‐type GaN nanorod framework supplies continuous electron pathways and photocarrier generation, while a TiS2 interlayer promotes interfacial electron transfer for proton reduction. Dual‐mode operation highlights mode‐

Influence of Oxidation State on the Catalytic Activity of Iron Catalysts for CO2 Fixation to Cyclic Carbonates

ChemSusChem, Volume 19, Issue 16, 27 August 2026.
Air stable bimetallic iron one‐component systems capable of CO2 cycloaddition to epoxides under 1 bar of pressure of CO2. In this work, one‐component iron catalysts for the atom‐economical reaction of CO2 with epoxides have been used as efficient catalysts for the carbon dioxide cycloaddition into cyclic carbonates in excellent yields.

Unraveling the Electrocatalytic Performance and Structural Stability of Ag Nanowire Gas Diffusion Electrodes for CO2 Reduction

ChemSusChem, Volume 19, Issue 15, 14 August 2026.
Silver nanowires (AgNWs) catalyze CO2 reduction into CO with high selectivity both in the three‐electrode cell and in the zero‐gap electrolyzer. While catalytic currents and selectivity are stable over hours, the AgNW shape undergoes restructuring and its surface chemistry changes.
