Calcination‐Induced Pore Evolution in TiO2 Supports Governing Ni Accessibility for Dry Methane Reforming

ChemistryOpen, Volume 15, Issue 5, May 2026.
Ni/TiO2 catalysts with tunable pore structures were developed to study how support calcination temperature affects Ni accessibility and dry reforming of methane (DRM, CH4 + CO2 → syngas). Low‐temperature TiO2 forms mesopores that trap Ni, while high‐temperature calcination generates macroporous/plate‐like structures that expose Ni and enhance catalytic

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.

Strain and grain size of TiO2 nanoparticles from TEM, Raman spectroscopy and XRD: The revisiting of the Williamson-Hall plot method

Results in Physics, 2018
The Williamson-Hall (W-H) equation, which has been used to obtain relative crystallite sizes and strains between samples since 1962, is revisited. A modified W-H equation is derived which takes into account the Scherrer equation, first published in 1918,
