Pickett Equation for the Description of Adsorption on Arbitrary Surfaces

open access: yesColloids and Interfaces, 2020
The theory of multilayer adsorption of gases, namely the Pickett equation, has been developed to the case of adsorption on arbitrary surfaces in a molecular and a topological approach. We present the prediction of the fractal dimension for the surface of
