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

Provenance and Petrological Evolution of Sand Injection Complexes: Insights From Heavy Mineral Analysis in the Paleogene Forearc Succession of the San Joaquin Basin

Basin Research, Volume 38, Issue 3, May–June 2026.
The study of heavy mineral assemblages with statistical analysis resolves provenance signatures and quantifies syn‐emplacement modification of sand injection complexes. Results demonstrate transformative petrological processes, including density‐dependent hydraulic sorting and mechanical grain degradation.

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.

Mangifera indica and Azadirachta indica‐Mediated Green‐Synthesized Anatase TiO2 Nanoparticles as Anode of Li‐Ion Batteries at Room and Elevated Temperature

Advanced Energy and Sustainability Research, Volume 7, Issue 4, April 2026.
Green‐synthesized TiO2 from Mangifera and Azadirachta leaves enables stable, high‐performance LIB anodes, boosted by residual carbon. Anatase TiO2 is a popular anode material for Li‐ion batteries (LIBs) due to its eco‐friendliness, stability, safer operation, and reversible performance.

Comparing photoelectrochemical water oxidation, recombination kinetics and charge trapping in the three polymorphs of TiO2

Scientific Reports, 2017
In this article we present the first comparative study of the transient decay dynamics of photo-generated charges for the three polymorphs of TiO2. To our knowledge, this is the first such study of the brookite phase of TiO2 over timescales relevant to ...

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 ...
