In this study, cerium modified TiO 2 catalyst was prepared and the performance on the photocatalytic degradation of Rhodamine B (RhB) in aqueous solution was evaluated. For the band gap engineering, three different percentages of Ce-doped TiO 2 (3, 5 and 7 % mol) were synthesized using the simple, efficient, and low-cost sol-gel method. Structural,...
The crystal structure and elastic and electronic properties of (Bi1-xFex)2Te3 were studied by first-principles calculations within the Density Functional Theory (DFT) scheme. We found that at zero GPa, the lattice parameters for Bi2Te3 are in good agreement with the available experimental and theoretical data. As Fe replaces bismuth, the lattice pa...
In this work, a comparative study between two processes was performed—biodegradation and photocatalysis, as an advanced oxidation process—to discover which one is more efficient to degrade Rhodamine B, a synthetic dye widely used in the textile and food industries. The advantage of this study is that it correlates treatment efficiency with the ecot...
Nowadays, the contamination caused by emerging pollutants is a global concern due to the lack of scientific evidence to demonstrate the risk or toxicity to humans due to the presence of pharmaceutical residues in the environment. This study aimed to identify and describe the disposal practices of unused and unwanted medications, as well as to analy...
El proyecto contribuye a impulsar, promover y fortalecer una cultura de la prevención, el cuidado y autocuidado de la población escolar para enfrentar la emergencia sanitaria por el SARS-CoV-2 y planear el sano retorno a los centros de formación. Destaca el papel de la gestión educativa, el trabajo colaborativo y multidisciplinar en colaboración co...
Las medidas establecidas para el control de COVID-19 ha modificado los estilos de vida de la población incidiendo sobre factores de riesgo, tales como; el desfase de los horarios de sueño y su calidad, selección y la cantidad de alimentos consumidos; sedentarismo y poca actividad física; un mayor tiempo destinado al uso de la tecnología; así como i...
The crystal structure, mechanical, electronic properties, as well as the electron-phonon constant of YB 6 under low pressure (<1.0 GPa) were investigated by first-principles density functional theory (DFT) within the bounds of the generalized gradient approximation (GGA). The calculated cell parameter a at zero pressure is in good agreement with th...
La industria petroquímica en México representa un papel fundamental dentro del sector energético y económico del país. Asimismo, la contaminación del suelo como resultado de la presencia del petróleo y sus derivados afecta la calidad del mismo y de manera directa e indirecta resulta en un potencial factor de riesgo para el ambiente y la salud human...
Actions taken to control the propagation of COVID-19 forced most activities to switch into an online environment. Education was no exception. In most of the cases the transition turned out well, and online education proved to be a good alternative to the traditional model. However, in the case of practical courses, the situation is quite different...
COVID-19 pandemic has changed the normal course of activities around the World. The measures implemented to slow down the spread of the disease and its impact on the health system have also suggested a change in population dynamics. In the educational aspect, the paradigm of the traditional education had to change completely to a remote environment...
In this paper, we report our theoretical prediction of a boron-rich binary compound, YB6, with Pm3̅m space group subjected to pressures from 0 to 50 GPa. Calculations of first principles are performed to investigate the elastic, vibrational and electronic structural properties using the Density Functional Theory (DFT) within the plane-wave pseudopo...
Recently, high ionic conduction has been reported in nanostructured materials. This increase in conductivity can be important in technological applications, including micro-Solid Oxide Fuel Cells, so the understanding of this phenomenon is essential. In this work, XRD, Raman spectroscopy, SEM, EDS maps, and UV-Visible spectroscopy measurements are...
An enhancement of the electrical conductivity has been found in nano-grain sized Ce{sub 0.9}Gd{sub 0.1}O{sub 2-} ceramics when measured in N (p{sub O}=3.5x10 atm) in comparison with the most commonly accepted values of bulk ionic conductivity. We first present the synthesis and characterisation of the nanoparticles later used for the preparation of...
In this article we discuss the synthesis of nanoparticles and the preparation of dense nanoceramics of Y-doped CeO2. We prepared the nanoparticles by the combustion method and characterised the nanopowders by XRD, SEM and TEM. The good sintering properties of these nanopowders allowed us to obtain very dense ceramics of Y-doped CeO2 and keep the gr...
In this article we discuss the synthesis of nanoparticles and the preparation of dense nanoceramics of Y-doped CeO2. We prepared the nanoparticles by combustion synthesis and characterized the nanopowders by X-ray diffraction, scanning electron microscopy (SEM), and transmission electron microscopy. The good sintering properties of these nanopowder...
An enhancement of the electrical conductivity has been found in nano-grain sized Ce0.9Gd0.1O2-delta ceramics when measured in N-2 (pO(2) = 3.5 x 10(-6) atm) in comparison with the most commonly accepted values of bulk ionic conductivity. We first present the synthesis and characterisation of the nanoparticles later used for the preparation of dense...
