    Análisis microfacial, paleontológico y geoquímico en carbonatos de la Formación el Abra, Cerritos, San Luis Potosí, México por Ramos Hernández, Jennifer

    Publicado 2018
    “…A group of 13 representative samples was selected which were analyzed by ICPMS and X-ray diffraction to know the elemental composition of trace elements and rare earth and mineral phases, respectively. The results obtained indicate that the El Abra Formation was deposited in a marine environment with good oxygenation, in a tectonic environment of passive continental margin in the absence of clay minerals…”

    Procesamiento y estudio preliminar de un material compuesto de matriz AlSi₁₀Mg reforzado con nanopartículas de Ti mediante aleado mecánico. por Sánchez Rico, Valentina

    Publicado 2020
    “…The results of the Vickers hardness show that with the addition of the nano particles and with the sintered one, it decreases; on the other hand, through the SEM and DRX the creation of new phases such as magnesium oxide and titanium oxide was observed in addition to observing some pores in certain microstructures. …”

    Evaluación teórica de la reflectancia en capas delgadas de Al/SiO2 depositadas mediante sputtering para aplicaciones en recubrimientos ópticos por Ortega Cabrera, Jesús Javier

    Publicado 2021
    “…For this, a methodology was developed that contemplates carrying out the deposition of the material at two different temperatures of the substrate, the angles at which the aluminum is deposited in its vapor phase were also modified by means of the sputtering technique and finally it was varied in two different values are the speed at which the aluminum atoms are deposited on the substrate. …”
