  1. From adsorption to condensation: The Zeta adsorption isotherm approach

    Yaghoubian Ghouchani, Sima2018

    The Zeta Adsorption Isotherm is based on the hypothesis that molecules adsorb on a solid surface as a collection of molecular clusters. The theory is extended to the steady, thermal disequilibrium states where a vapour at a temperature T^V is exposed to a solid surface at a lower temperature, T^S, …
