Effect of sintering cycle on the strength and translucency of multilayered zirconia

Journal of Prosthodontics, EarlyView.
Abstract Purpose A newly introduced sintering protocol promises to offer higher translucency while not significantly compromising the flexural strength of the material. However, the effect of the novel sintering protocol has not been thoroughly validated.

Simple (YGa)2O3/F‐SnO2 Heterojunction‐Based Solar‐Blind Ultraviolet Photodetector Operable in Two Modes With Superb Performance

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
Yttrium doping was proposed to expand the bandgap and inhibit the oxygen vacancies of Ga2O3 to form (YGa)2O3 alloy with reduced background carriers and trap centers. Beneficially, simple vertical‐structured (YGa)2O3/FTO heterojunction photodetectors exhibit superb performance with particularly low dark current and fast photoresponse in both self‐driven

Alkaline Leaching: A Facile Surface Activation Strategy to Improve the Reactivity of Air Electrodes for Solid Oxide Fuel Cells

Advanced Materials, Volume 38, Issue 33, 12 June 2026.
This study shows that alkaline leaching of PrBa0.8Ca0.2Co2O5+δ under anodic bias selectively removes Ba and Ca, forming a cobalt‐rich and amorphous layer. The modified surface significantly boosts ORR activity, offering a simple and effective strategy to improve electrochemical device performance.
