    • Study of metallocene supported on porous and nonporous silica for the polymerization of ethylene 
      Quijada Abarca, Juan; Rojas, Rene; Alzamora, Luis; Retuert, Jaime; Rabagliati, Franco M. (1997)
      Porous and nonporous silicas are good supports for the synthesis of coordinative heterogeneous catalysts for ethylene polymerization. The catalytic activity of nonporous Aerosil depends critically on the percentage of ...
    • Temperature induced disorder in β-Zr 
      Gutiérrez Gallardo, Gonzalo; Kiwi Tichauer, Miguel; Ramírez, Ricardo (Sociedad Mexicana de Fisica, 1998)
      The behavior of free surfaces and of grain boundaries of a bcc Zr system, close to the melting temperature, are investigated using molecular dynamics in combination with a tight-binding potential. Our system consists in ...
