Solid State characterization employing gravimetric and volumetric physisorption technologies including vacuum, dynamic flow, high pressure, cryogenic, ambient and high temperature techniques. Additionally, we study concentrated liquid phase dispersions using light scattering technology. Thin film analysis by light scattering and gravimetric techniques. Diffusivity, permeability and solubility of thin films. Pore analysis using BET as well as capillary flow through porometry.
