    Effect of lanthanum on the catalytic properties of PtSn/γ-Al2O3 bimetallic catalysts prepared by successive impregnation and controlled surface reaction. por Del Angel Montes, Gloria Alicia, Bonilla Barenca, Alfredo, Peña Méndez, Yolanda, Navarrete Barbosa, Juan Ignacio, García Fierro, José Luis, Acosta, D. R.

    Publicado 2003
    “…When the CSR preparation method was used, reduced Pt0 was observed and oxidized Pt2+ was not detected. As the lanthanum content increased a diminution in cyclohexane dehydrogenation and n-heptane conversion was observed. …”

    Accelerated and natural carbonation of concretes with internal curing and shrinkage/viscosity modifiers por Durán Herrera, Alejandro, Mendoza Rangel, José Manuel, Santos Rodríguez, Edgar Ulises de los, Vázquez, F., Valdez Tamez, Pedro Leobardo, Bentz, Dale P.

    Publicado 2015
    “…For all seven concrete mixtures, a good correlation between accelerated (lab) and natural (field) measured carbonation coefficients is observed. Conversely, there is less correlation observed between the specimens’ carbonation resistance and their respective 28 days compressive strengths, with the mixtures containing the shrinkage/viscosity modifier specifically exhibiting an anomalous behavior of higher carbonation resistance at lower strength levels. …”
