TL;DR: An in situ electron paramagnetic resonance (EPR) study has been carried out for anatase and rutile TiO(2) nanoparticles at liquid helium (He) temperature under UV irradiation and results evidence the crystallinity of titania phases.

TL;DR: In this article, the results indicate that phosphorus-doping into the TiO2 lattice decreases the particle size, increases the thermal stability of titania, and retards the phase transition from anatase to rutile.

TL;DR: Definite assignment of the boron oxidation state will contribute to the preparation, characterization, and understanding of B-TiO2 photoactivity under visible light which has been the subject of extensive work in the past few years.

TL;DR: Monitoring the dynamics of photogenerated charge carriers trapping in deep traps and trapped electron-hole recombination in UV irradiated anatase TiO2 powders by EPR spectroscopy reveals that the strategy of using low temperatures contributes to the stabilization of the charged pair states for hours by reducing the rate of electron- hole recombination processes.

TL;DR: In this paper, the 14N nuclear quadrupole coupling (NQC) constants and asymmetry parameters for a series of small nitrogen-containing imidazole derivatives are investigated, by using density functional theory (DFT), in three clearly distinct environments: as free molecules, in the solid state, and in solution.
