Multicomponent Rare‐Earth Monosilicate Reactions With Calcium‐Magnesium Aluminosilicate

Journal of the American Ceramic Society, Volume 109, Issue 2, February 2026.
ABSTRACT High‐temperature reactions of multicomponent rare‐earth monosilicates (REMS) with calcium‐magnesium aluminosilicate (CMAS) were investigated at 1300°C for 24 h. Three compositional series were tested, each ranging from 1‐cation to 4‐cation REMS, with cations selected to interrogate compositional effects on CMAS reactivity. The final members of

Interdiffusion kinetics of yttria and alumina

Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
Abstract The interdiffusion kinetics of yttria‐alumina diffusion couples produced by spark plasma sintering (SPS) were investigated at 1350°C, 1425°C, and 1500°C. The SPS diffusion couples were heat‐treated in air at their sintering temperatures for 0, 24, and 96 h.

Eu3+ as a structural probe in yttrium silicates through photoluminescence emission spectra

Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
Abstract This work presents the first steps in using Eu3+ as a structural probe using photoluminescence (PL) emission spectra. The sol–gel synthesis of four Eu3+‐doped powders encompassing seven phases of the yttrium silicate phase system is detailed.

Heat Transfer Through Plasma-Sprayed Thermal Barrier Coatings in Gas Turbines: A Review of Recent Work

, 2009
A review is presented of how heat transfer takes place in plasma-sprayed (zirconia-based) thermal barrier coatings (TBCs) during operation of gas turbines. These characteristics of TBCs are naturally of central importance to their function. Current state-

Deep Reinforcement Learning–Based Multiobjective Control of Hybrid Building Envelopes: Integrating Adaptive Façades, Passive Radiative Cooling, and Indoor Air Quality Management Across Iranian Climates

Indoor Air, Volume 2026, Issue 1, 2026.
Buildings consume 30%–40% of global energy while simultaneously exposing occupants to poor indoor air quality (IAQ) that impairs health and cognition. This study addresses the challenge of achieving simultaneous energy efficiency, thermal comfort, and healthy indoor environments through intelligent building control.
