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.

Thermal Cycling Behavior of Air Plasma-Sprayed and Low-Pressure Plasma-Sprayed Environmental Barrier Coatings

, 2021
Yb2Si2O7/Si environmental barrier coatings (EBCs) were produced by air plasma spray (APS) and low-pressure plasma spray (LPPS) processes. The phase composition, microstructure, and bonding strength of APS and LPPS EBCs were investigated.

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.

Development of thermally sprayed environmental barrier coatings [PDF]

, 2017
Ceramic matrix composites (CMCs) are candidate materials for high-temperature applications such as gas turbines. As corrosion by water vapor and deposits is a limiting issue, the application of suitable environmental barrier coatings (EBCs) is inevitable.
