Machine learning‐based microstructure identification in lithium silicate dental glass‒ceramics

Journal of the American Ceramic Society, Volume 108, Issue 11, November 2025.
Abstract This study explores the application of machine learning (ML) to identify and quantify the microstructure of lithium silicate based dental glass‒ceramics (DGCs), a material at the forefront of prosthetic dental applications due to its good mechanical properties and aesthetics.

Thermo-elastic micromechanical modeling of tetragonal ZrO2 with a herringbone microstructure inherited from the cubic phase

Materials & Design
The distribution of residual stresses at the crystal scale is investigated in several random polycrystalline aggregates of zirconia. The underlying stochastic model generates tetragonal crystals forming three-dimensional herringbone microstructures ...

Examining the effect of temperature on steam oxidized silicon bond coats

Journal of the American Ceramic Society, Volume 108, Issue 10, October 2025.
Abstract The SiO2 thermally grown oxide (TGO) is a life‐limiting factor for environmental barrier coatings (EBCs). EBCs in aeroengines face a variety of operating temperatures so the resulting effect on SiO2’s crystallinity and growth are necessary to better understand EBC failure.

Effect of sintering temperature on optical properties and microstructure of translucent zirconia prepared by high-pressure spark plasma sintering

Science and Technology of Advanced Materials, 2011
Aiming to characterize the effect of sintering temperature on transparency of zirconia, we have evaluated the optical properties and microstructure of translucent cubic zirconia prepared by high-pressure spark plasma sintering (SPS) at 1000–1200 circleC.

Coupled electromigration–nanoindentation study on dislocation nucleation in SrTiO3

Journal of the American Ceramic Society, Volume 108, Issue 10, October 2025.
Abstract Modern functional oxides are mainly engineered by doping, essentially by tuning the defect chemistry. Recent studies suggest that dislocations offer a new perspective for enhancing the mechanical and physical properties of ceramic oxides. This raises the question regarding the interaction between dislocations and point defects in ceramics ...

Water Oxidation to Hydrogen Peroxide Over a Super‐Aerophilic Graphite Catalyst

Advanced Materials, Volume 37, Issue 35, September 4, 2025.
Design of super‐aerophilic graphite catalyst capable of trapping in situ produced oxygen gas on its surface under the electrolyte environment. By so doing, it is able to moderate intermediate species binding, which is critical to enabling the two‐electron water oxidation reaction to hydrogen peroxide.

Reactions of yttria-stabilized zirconia with oxides and sulfates of various elements [PDF]

The reactions between partially stabilized zirconia, containing 8 weight-percent yttria, and oxides and sulfates of various elements were studied at 1200, 1300, and 1400 C for times to 800, 400, and 200 hours, respectively.
