UV-Absorption—The Primary Process in Photocatalysis and Some Practical Consequences
TiO2 photochemistry studies generally address reactions of photogenerated charge-carriers at the oxide surface or the recombination reactions which control the proportion of charge carriers that reach the surface.

Strain‐driven Ru inward migration creates confined RuO2/Pt mosaic heterointerfaces within a PtNi multiframe. These interfaces enable redox‐asymmetric Pt–Ru coupling that stabilizes Ru4+, suppresses lattice oxygen participation, and promotes highly durable acidic oxygen evolution.

Preparation Techniques of TiO2 Nanofluids and Challenges: A Review
Titanium dioxide (TiO2) has been used extensively because of its unique thermal and electric properties. Different techniques have been used for the preparation of TiO2 nanofluids which include single-step and two-step methods. In the natural world, TiO2

Theoretical study on copper's energetics and magnetism in TiO2 polymorphs
We carried out density functional theory calculations to model the electronic structure and the magnetic interactions in copper doped anatase and rutile titanium dioxide in order to shed light on the potential of these systems as magnetic oxides using ...

Ore content of Avramivske and Zakhidne deposits (Novomyrhorod gabbro-anorthosite massif)
The geological structure and ore content of the Avramivske and Zakhidne phosphate-titanium deposits located in the southern part of the Korsun-Novomyrhorod pluton are characterized. Within these deposits, phosphate-titanium mineralization is contained in

Ferromagnetism at 300 K in spin-coated films of Co doped anatase and rutile TiO2
Thin films of Ti1-xCoxO2 (x=0 and 0.03) have been prepared on sapphire substrates by spin-on technique starting from metalorganic precursors. When heat treated in air at 550 and 700 C respectively, these films present pure anatase and rutile structures ...

Interfacial Ru–O–W Orbital Coupling Enables Lattice Oxygen Stabilization for Enhanced Acidic OER
A RuO2/WO3 electrocatalyst with strong interfacial Ru–O–W bonds exhibits optimized Ru–O interactions, enhancing intrinsic activity and stability for acidic OER. The WO3 support modulates the electronic structure of RuO2 and promotes oxo‐intermediate deprotonation, delivering a low overpotential of 203 mV at 10 mA cm−2 and sustained operation beyond 200
