Cluster expansions for physical adsorption
Physica, 1971Abstract Adapting Bellemans's cluster expansions for the change of the surface tension of a solvent in the presence of a solute to the case of physical adsorption, expressions for the spreading pressure and the specific amount of adsorption are derived in ascending powers of the pressure of the gas.

Collective effects in physical adsorption
The Journal of Chemical Physics, 1978The collective electronic polarization waves occurring in a regular two-dimensional lattice of rare gas atoms adsorbed on a metallic surface are studied, including interactions mediated by the metallic substrate. The atoms are represented as three-dimensional isotropic harmonic oscillators interacting via electrostatic dipolar forces.

Physical Adsorption Validity in Flotation
Journal of Mining Science, 2018The authors analyze collecting capacity of desorbable species of xanthates. Desorbable species of the reagent are understood as the species capable to transfer from a mineral particle to air bubble, i.e. to gas–liquid interface, at the moment of rupture of an interlayer between these interacting objects.

Physical Adsorption: Forces and Phenomena
1997Abstract About twenty years ago, as a rapid expansion of surface physics was underway, Greg Dash and Bill Steele published a pair of influential monographs on physical adsorption defining the language and identifying a family of issues that are common to most work in the field.

Adsorption and Physical Property Methods
1958The analysis of the viscous fractions of petroleum by physical property correlations, and other short cut methods, is a very fascinating one. This approach is very different from the complete separation used by API Research Project 6 (19). The American Petroleum Inst.

Molecular interactions for physical adsorption
Chemical Reviews, 1993Modeling of the physical interactions of molecules with solid surfaces has been a subject of considerable interest for many years. These potentials play a central role in the theory and computer simulations of the thermodynamic, structural, and dynamic properties of adsorbed films.

Molecular Specificity in Physical Adsorption
1960Publisher Summary This chapter reviews the molecular specificity in physical adsorption and discusses the various aspects of the perturbation of solid adsorbents. When physical adsorption takes place on solid surfaces, the free energy is reduced and also the surface tension.
