Interpreting zirconium-in-rutile thermometric results

open access: yes, 2015
At first sight, experimental results and observations on rocks suggest that the Zr content in rutile, where equilibrated with quartz and zircon, should be a useful thermometer for metamorphic rocks.

Sulfonated‐TiO2 Nanorod–Reinforced PEO Composite Solid Electrolytes for High‐Voltage Solid‐State Lithium Metal Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study introduces a high‐performance composite solid electrolyte (CSE) utilizing actively sulfonated TiO2 (STiO2) nanorods within a PEO matrix. The 1D ceramic network chemically promotes LiTFSI dissociation and creates continuous fast‐hopping pathways for Li+ ions, delivering an ionic conductivity of 1.5 × 10−4 S cm−1 at room temperature, an ...

Decolorization of Ponceau Red 4R with TiO2/ZnO: Effect of calcination temperature and Fe addition

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract The photocatalytic degradation of azo dyes using semiconductor oxides has emerged as a promising strategy for wastewater remediation. In this study, pure, mixed, and Fe‐doped oxide catalysts based on Zinc Oxide and Titanium Dioxide were synthesized and evaluated for the degradation of Ponceau 4R under ultraviolet irradiation.

Geochemistry and Geochronology of Magmatic Rocks in Southwestern and Northeastern Cambodia: Implications for the Tectonic Evolution and Metallogenesis of the Loei Fold Belt

open access: yesGeological Journal, EarlyView.
The composition of intrusive rocks suggests that the magma was likely generated in a subduction‐related setting. The arc crustal thickness in the Phnom Sro Ngam and Halo Prospects was probably < 40 km during emplacement. Zircon U–Pb age range indicates a correlation with Loei Fold Belt magmatic activity.

Exploring the Chemical Complexity and Toxicological Behaviour of Semi‐permanent Make‐Up Pigments: A Systematic Review

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Semi‐permanent make‐up (SPMU), or micropigmentation, involves implanting pigments into the dermal layer of the skin for cosmetic enhancement. Unlike topical cosmetics, which are rapidly cleared from the body, SPMU pigments persist in living tissues, raising unique toxicological considerations.
