Journal ArticleDOI
Influence of Thermal Annealings in Argon on the Structural and Thermochromic Properties of \mathrm{MoO}_{3} Thin Films
Miguel A Arvizu,M. Morales-Luna,M. Pérez-González,E. Campos-González,Orlando Zelaya-Angel,S. A. Tomás +5 more
TL;DR: The effect of thermal annealing in an inert atmosphere (argon) on the structural and thermochromic properties of thin films was investigated in this article, where the authors showed that the properties of these thin films increased with the temperature in the analyzed range.
Journal ArticleDOI
A BiVO4 photoanode grown on porous and conductive SnO2 ceramics for water splitting driven by solar energy
A. N. Bondarchuk,Iván Corrales-Mendoza,Josue Amilcar Aguilar-Martínez,S. A. Tomás,Daniel A. Gómez-Caiceros,Arturo Hernandez-Mendez,Frank Marken +6 more
TL;DR: In this article, the authors introduced BiVO4-photoelectrodes grown on conductive bulk SnO2-Sb2O5 ceramics acting as a porous substrate.
Journal ArticleDOI
Atmospheric ethene concentrations in Mexico City: Indications of strong diurnal and seasonal dependences
TL;DR: In this article, the variation of the ethene content in atmospheric samples simultaneously collected in stainless-steel containers at three stations of the local government's air quality monitoring network in November 1999 and March 2000 was assessed.
Journal ArticleDOI
Chemical synthesis and optical, structural, and surface characterization of InP - In2O3 quantum dots
D.A. Granada-Ramírez,J.S. Arias-Cerón,M. Pérez-González,M. Pérez-González,Juan Pedro Luna-Arias,Alfredo Cruz-Orea,P. Rodríguez-Fragoso,J. L. Herrera-Pérez,M. L. Gómez-Herrera,S. A. Tomás,F. Vázquez-Hernández,A.A. Durán-Ledezma,J.G. Mendoza-Alvarez +12 more
TL;DR: InP-In2O3 colloidal quantum dots synthesized by a single-step chemical method without injection of hot precursors (one-pot) were investigated and the effect of the tris(trimethylsilyl)phosphine, P(TMS)3, precursor concentration on the QDs properties was studied to effectively control the size and shape of the samples with a minimum size dispersion.
Journal ArticleDOI
Optical characterization of CdS semiconductor nanoparticles capped with starch
TL;DR: In this paper, the size of CdS quantum dots was measured using high resolution transmission electron microscopy (HRTEM) and X-ray diffraction (XRD) and the average diameter (d )o f nanoparticles spanned the range 4.8 ± 0.4 nm when the pH of the solution was varied within the range 10-14.
