[Todos] Visitante y conferencia

[Susana Hernandez]

	El proximo martes 7/8 nos visita el Prof. Aldo Migone de 
la U. de Carbondale, Ill. Es fisico experimental especialista en 
adsorcion en nanoporos y dara una charla a las 15:00 en el Aula de 
Seminario. Se adjunta titulo y abstract (la charla sera en 
castellano)

	Quedan todos invitados (disculpen por la superposicion con 
la Giambiagi pero no quedo otra posibilidad)

	Saludos,

	TITULO Y ABSTRACT

"Gas Adsorption on Carbon Nanotubes: The Effect of Molecular Size and
Binding Energy on Equilibrium and Kinetic Properties"

We will present the results of adsorption isotherm experiments for Ar,
Xe and CF4 on bundles of carbon nanotubes.
The isotherm results will be used to determine the degree of occupation
of the different sets of adsorption sites present on the bundles.
The results will be compared to computer simulations for these systems.
Adsorption isostherm measurements allow the determination of the
isosteric heat of adsorption as a function of coverage. The isosteric
heats of adsorption of the various gases will be presented, and the
results will be discussed in terms of molecular size.
We will also present experimental results regarding the adsorption
kinetics for various gases on nanotube bundles, and we will compare
them with recent theoretical calculations.
