Influence of the Capping Ligand on the Band Gap and Electronic Levels of PbS Nanoparticles through Surface Atomistic Arrangement Determination por García Gutiérrez, Diana Fabiola, Hernández Casillas, Laura Patricia, Cappellari, Maria Victoria, Fungo, Fernando, Martínez Guerra, Edgar, García Gutiérrez, Domingo Ixcóatl

“…These observations suggest that the electrooptical properties of PbS nanoparticles are not only determined by their size, through quantum confinement effects, but also strongly affected by the atomistic arrangement on the nanoparticle surface, which is determined by the capping ligand nature.…”

Implementation of an online emergency education programme at a public university in Mexico por González Barranco, Patricia, Balderas Rentería, Isaías, Esquivel Ferriño, Patricia Cristina, Gracia Vásquez, Yolanda Araceli

“…Most of the educational programmes are in person, only a few continual education courses were given remotely, for which UANL used a platform called Nexus, for all media and educational resources. This platform is also used for University students to submit and evaluate homework for the in-person classes. …”

Effects of pericytes and colon cancer stem cells in the tumor microenvironment por Garza Treviño, Elsa Nancy, Delgado González, Paulina, Valencia Salgado, Carlos I., Martínez Garza, Alejandra Mayela

“…In recent years, it has been shown that the main reason for drug resistance is the presence of colon cancer stem cells (CSC). Pericytes are also capable of tumor homing and are important cellular components of the tumor microenvironment (TME), contributing to the formation of vessels and promoting metastasis; however, they have not been considered very important as a therapeutic target in cancer. …”

Conditional betas and Market re-definition: Revisiting the capital asset pricing model with Mexican data por Treviño Villarreal, María de Lourdes

“…The results suggested, however, that it is necessary to allow for time variations in betas as well in order to explain the variations of the monthly average returns. A size effect was also found, although it is not very important. In spite of the empirical support found for the conditional CAPM over the static CAPM, both specifications explain about half of the monthly average return variation, which calls for differences in the pricing of risk between developed and emerging countries…”

Two-stage melting of au-pd nanoparticles por Mejía Rosales, Sergio, Fernández Navarro, Carlos Javier, Pérez Tijerina, Eduardo, Montejano Carrizales, Juan Martín, Yacamán, Miguel José

“…We found that the melting transition temperature has a strong dependence on the relative concentrations of the atomic species. We also found that, previous to the melting transition, the outer layer of the nanoparticle gets disordered in what can be thought as a premelting stage, where Au atoms near the surface migrate to the surface and remain there after the particle melts as a whole. …”
