Various heterogeneous catalytic reactions, when performed on a flux reactor (i.e. on open systems) under UHV conditions display complex spatiotemporal patterns. Specifically, TPR, Work Function (WF) measurements (both g...

Uno de los aspectos más importantes en la formulación de dispersiones de aplicación farmacéutica, es el conocimiento de aquellas propiedades fisicoquímicas, que involucran fenómenos de superficie e interfase en sis...

Formulações de matrizes hidrofílicas para administração oral usando polissacarídeos como transportadores para libertação modificada de fármacos têm sido amplamente investigadas. No presente estudo, avaliamos ...

This chapter presents different phenomena that arise when nanomaterials reach the environment, with emphasis in water systems. Transformations on the surface of nanomaterials and nanoparticles because of adsorption of ma...

En este trabajo se han estudiado varios de los diferentes procesos que tienen lugar durante el calentamiento y la fusión de superficies de aceros al carbono producidos por irradiación con luz infrarroja coherente. En p...
