Synthesis and characterization of metal nanoparticles by pulsed laser ablation in liquid media (PLAL) por Mendivil Palma, María Isabel

“…In this thesis we report an easy, fast, alternative-novel and one-step method for the preparation of pure and stable (in some cases) noble metal nanoparticles, viz Pulsed Laser Ablation in liquid media; this method presents significant advantages over chemical routes as: pure metal nanoparticles production, less aggregation, non-vacuum requirements, non-toxic agents are required, size and shape tunability, between others. …”

Internal Migration in Mexico in the year 2000. por Pimienta Lastra, Rodrigo, Vera Bolaños, Marta, Shea, Michael, Gutiérrez Cárdenas, Elena Marcia

“…The aim was to establish the volume of migration and the characteristics of the localities (birth and residence) and, at the same time, provide interpretations of these phenomena within some established theoretical frameworks. Methodologically, the principal flows of migration between states of the Republic were established and correlated with the size of the localities to which migrants are attracted. …”
