Study of the effect of oxygen vacancy content on the photocatalytic activity of TIO2 nanoparticles
(Benemérita Universidad Autónoma de Puebla, 2021-11)
"TiO2 is one of the most popular metal oxide semiconductors utilized for advanced oxidation processes (AOPs), including in photocatalysis. As the photocatalytic behavior of a metal oxide is known to be controlled by oxygen ...
Effects of Cation Vacancies in the Phonon Raman Spectra of LaMnO3
(Wiley VCH Verlag, 2000-07)
Raman spectra of La1–xMn1–xO3 (x = 0, 0.01, 0.017, 0.022, and 0.035) and La0.91–δMn1–δO3 polycrystalline samples, taken at T = 10 K and room temperature, are presented. All La1–xMn1–xO3 samples show at T = 10 K the presence ...
The influence of the morphology of 1D TiO 2 nanostructures on photogeneration of reactive oxygen species and enhanced photocatalytic activity
(Elsevier B.V., 2019)
The influence of morphology in one-dimensional (1D) TiO 2 nanostructures—specifically nanotubes (TNT), nanofibers (TNF), nanorods (TNR), and nanowires (TNW)—on the photogeneration of reactive oxygen species (ROS) and the ...

The two gap transitions in Ge1–xSnx: Effect of non-substitutional complex defects
(American Institute of Physics, 2016-09-13)
The existence of non-substitutional β-Sn defects in Ge1-xSnx alloys was confirmed by emission channeling experiments [Decoster et al., Phys. Rev. B 81, 155204 (2010)], which established that, although most Sn enters ...
