Durante el presente trabajo de tesis se estudió el proceso de síntesis de nanopartículas de oro soportadas en óxidos reducibles (CeO2, Nb2O5, FeOOH, MnFeOOH y CoFeOOH) y la aplicación de estos sistemas en la hidroge...

Los tratamientos antipsoriásicos utilizando antralina presentan varias desventajas debido principalmente a las propiedades físico-químicas de ésta, a sus efectos adversos y a su formulación. La antralina es insolub...

The relationship between co-integration and error correction models, first suggested in Granger (1981), is here extended and used to develop estimation procedures, tests, and empirical examples. If each element of a vect...

We present an efficient scheme for calculating the Kohn-Sham ground state of metallic systems using pseudopotentials and a plane-wave basis set. In the first part the application of Pulay's DIIS method (direct inversion ...
