<i>"Gas Adsorption on Carbon Nanotubes: The Effect of Molecular Size
and Binding Energy on Equilibrium and Kinetic Properties"
</b>(Idioma de la presentación: Español)<br><br>
</i><b>Dr. Aldo Migone<br>
Department of Physics<br>
Southern Illinois University<br><br>
</b>We will present the results of adsorption isotherm experiments for
Ar, Xe and CF4 on bundles of carbon nanotubes.<br>
The isotherm results will be used to determine the degree of occupation
of the different sets of adsorption sites present<br>
on the bundles. The results will be compared to computer simulations for
these systems. <br>
Adsorption isostherm measurements allow the determination of the
isosteric heat of adsorption as a function of coverage.<br>
The isosteric heats of adsorption of the various gases will be presented,
and the results will be discussed in terms of <br>
molecular size. We will also present experimental results regarding
the adsorption kinetics for various gases on nanotube<br>
bundles, and we will compare them with recent theoretical
calculations.<br><br>
