In Situ SrF2 Crystallization in Transparent Germanate Glass‐Ceramics Driven by Erbium for NIR and MIR Applications

Journal of the American Ceramic Society, Volume 109, Issue 7, July 2026.
ABSTRACT Transparent oxyfluoride glass‐ceramics combining broad ultraviolet‐to‐mid‐infrared transmission with enhanced rare‐earth luminescence are promising materials for mid‐infrared photonic applications. In this work, erbium‐doped indium‐germanate oxyfluoride glasses exhibiting good glass‐forming ability under conventional melt–quenching conditions ...

A chemical threshold controls nanocrystallization and degassing behaviour in basalt magmas

Communications Earth & Environment, 2022
Nanocrystallization in experiments on basalt melts and glasses from Mt. Etna and Stromboli is mainly triggered by undercooling-driven oversaturation in TiO2 and FeO, which could bias viscosity measurements and affect magma dynamics during decompression.

Copper Nanocrystallization in Anodic Oxide Films of Ti–Cu‐Based Bulk Metallic Glass and Its Effect on the Corrosion Resistance and Cytocompatibility

Advanced Engineering Materials, Volume 28, Issue 11, 3 June 2026.
Viktoriia Shtefan, Thorgund Nemec, Ute Hempel, Annett Gebert and coworkers demonstrate that anodic treatment of Ti–Cu‐based metallic glass in a nontoxic pyrophosphate electrolyte forms a protective bilayered Ti/Zr‐oxide film enriched with Cu nanocrystals.

Structural Modulation of Magnetic Softness in Fe‐Based Amorphous Alloys via Pulse Current Training

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Fe‐based amorphous alloys, despite their intrinsically low magnetocrystalline anisotropy, suffer from quasi‐dislocation dipoles and localized stress fields that impede domain‐wall motion and increase coercivity. Here, we introduce pulse current training (PCT) as an energy‐efficient technique to overcome these limitations in a Fe76Si9B10P5 ...

Effect of Early‐Stage Crystallization on the Mechanical Properties of Transparent Niobium Silicate Glass Ceramics

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
ABSTRACT Although various strengthening strategies are being exploited to address the inherent brittleness of glasses, they often fail in integrating fracture resistance with preserved transparency, making the pursuit of robust yet transparent glass‐based materials a compelling challenge.
