Intrinsic Hardness Evolution and Indentation Size Effect Modeling in Cu/Co Doped ZnO, TiO2, and SnO2

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
ABSTRACT Metal oxides such as ZnO, TiO2, and SnO2 are widely used in structural and functional applications; however, their micromechanical performance is often limited by pronounced indentation size effects and surface‐related deformation behavior.

Interference of TiO2 in Fricke Dosimetry: Adsorption Mechanisms and Dose Measurement Challenges under Gamma Irradiation

ChemistryOpen, Volume 15, Issue 4, April 2026.
The presence of TiO2 in Fricke dosimetric systems introduces complex interferences under gamma irradiation. Adsorption of Fe2+/Fe3+ ions, coupled with radiolytic and surface‐mediated processes, alters redox equilibria and apparent absorbed dose values, highlighting critical challenges in chemical dosimetry applied to heterogeneous radiolytic ...
