Enhanced Third‐Order Nonlinear Optics From In Situ Grown Lead‐Free Cs2AgInCl6 Double Perovskite Nanocrystals in Chalcogenide Glass

Nanophotonics, Volume 15, Issue 10, 27 May 2026.
This work successfully achieves the in situ nanocrystallization of lead‐free Cs2AgInCl6 double perovskite within a chalcogenide glass host. The novel composite demonstrates a remarkable synergy, leading to a strong enhancement in third‐order nonlinear optical properties and a substantially improved optical limiting response, thereby offering a stable ...

Failure Mechanisms and Fault Evolution in All‐Solid‐State Batteries: From Materials to Cell‐Level Degradation

Battery Energy, Volume 5, Issue 3, May 2026.
The degradation of all‐solid‐state batteries stems from coupled chemo‐electro‐mechanical interactions across materials, interfaces, and cell structure. This review systematically analyzes failure mechanisms involving material instability, interfacial contact loss, and stress evolution, offering guidance for battery design.

High‐Cycle Fatigue Behavior and Deformation Mechanisms of Al0.5CoCrFeNi High‐Entropy Alloy by Laser Powder Bed Fusion

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Laser powder bed fusion (LPBF) can fabricate high‐entropy alloys (HEAs) with refined microstructure and enhanced mechanical properties. However, the deformation and fatigue mechanisms of Al‐containing HEAs produced by LPBF remain unclear. In this work, we systematically investigate the tensile properties, deformation mechanisms, and high‐cycle

Viscosity of Trachytic Melt Constrained by Integrated Rheological and In Situ Spectroscopic Analyses: Insights From the Agnano‐Monte Spina Eruption (Campi Flegrei, Italy)

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Quantifying the viscosity of hydrous volcanic melts is essential for understanding ascent dynamics, degassing efficiency, and fragmentation, yet laboratory measurements may be compromised by syn‐analytical evolution in melt structure at the nanoscale, thus yielding viscosity values not representative of a homogeneous melt phase.

Rare‐Earth‐Induced Fluoride‐Rich Local Structures Governing BaF2 Nanocrystallization in Oxyfluoride Glasses

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
This figure schematically illustrates the formation of BaF2‐like precursor structures in BaF2–ZnO–B2O3 oxyfluoride glass. Rare‐earth ions attract surrounding fluoride ions due to their higher field strength, leading to the formation of fluorine‐rich local environments.

Effect of Worm‐Like Amorphous Phase on Corrosion Resistance and Antibacterial Properties of NiTiCu Alloy

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT By adding CuO, the worm‐like amorphous phase and atomic clusters were simultaneously introduced, enabling the (Ni40Ti40Cu20)99.9O0.1 alloy micron columns to exhibit a uniform flow strain of over 40% and a strength of over 2.5 GPa during compression.
