  • Cabana García, Nancy Cecilia (2020-05-29)
    Esta tesis contribuye al entendimiento de geometrías, energías de interacción y capacidad de adsorción de químicos volátiles como lo son el tolueno y el CO2 en las zeolitas. Para ello se trabajó desde la teoría con el ...
  • Kopprio, Leonardo Hugo (2019-06-03)
    Different steady-state characterization techniques based on photoconductivity-related measurements are investigated. A detailed explanation is presented on how to implement the steady-state photoconductivity under a uniform ...
  • Forzani, Luisina (2019-03-25)
    Nanostructured porous anodic alumina membranes (NPAA) and porous silicon under the forms of mesoporous (PS) and macroporous (MPS) silicon were studied and used as matrices in nanocomposites. We deposited nickel into NPAA ...
  • Rodríguez Sotelo, Sindy Julieth (2019-03-20)
    Graphene is a bidimensional of carbon allotrope, with unique physical and chemical properties. The graphene is a flexible material, lightweight, transparent, with high charge mobility and high surface area, among others. ...
  • Quintero Riascos, Vanessa Alexandra (2019-05-17)
    The formation of positive/negative ions during the charge exchange in proton collisions with a metal surface of Cu(111) and different C60/Cu(111) films (different thickness) is experimentally and theoretically analyzed. ...
  • Cencha, Luisa Guadalupe (2018-12-19)
    The dynamic of capillary imbibition of various polymers in porous silicon and anodic alumina matrices was studied using interferometric techniques. The analysis of the filling dynamics allows one to investigate the polymer ...
