    Deposition of BiOBr thin films by thermal evaporation and evaluation of its photocatalytic activity por López Cuéllar, Enrique Manuel, Martínez de la Cruz, Azael, Chávez Torres, N., Olivares Cortez, José Luis

    Publicado 2015
    “…The analysis by XRD of the thin film deposited confirmed the formation of BiOBr, showing a high degree of specific crystal orientation in {0 0 1} planes. In the same way, SEM analysis showed that the deposition of oxide took place by formation of plates and small particles with shape of flowers. …”

    Molecular dynamics of free and graphite-supported Pt-Pd nanoparticles por Fernández Navarro, Carlos Javier, Mejía Rosales, Sergio

    Publicado 2013
    “…The melting transition temperature was found to increase when the particle is on the graphite support, with an increase at least 180 K higher than that of the same-sized free nanoparticle. The results of the density distributions perpendicular to the surface indicate that the Pd atoms have a tendency to remain at the surface, and the Pd atoms wet the graphite surface more than the Pt atoms, while root mean squares suggest that surface melting starts from the cluster surface, and surface melting was seen in both free and graphite-supported nanoparticles. …”
