Monolayer sorption of neon in mesoporous silica glass as monitored by WAXS

Abstract

We report measurements of the x-ray scattering intensity as mesoporous glasses are filled with Neon. We outline a simple model to account for the non-linear increase in the intensity of the first peak in a liquid-like diffraction pattern as a monolayer is formed. This allows us to demonstrate an approach for surface area determination which does not rely on thermodynamic models, and is therefore complimentary to existing models.
