Free Energy Formalism for Particle Adsorption

open access: yes, 2005
The equilibrium properties of particles adsorption is investigated theoretically. The model relies on a free energy formulation which allows to generalize the Maxwell-Boltzmann description to solutions for which the bulk volume fraction of potentially ...

A Molecular Dynamics Simulation on the Methane Adsorption in Nanopores of Shale

open access: yesComputation
Gas adsorption in nanoscale pores is one of the key theoretical bases for shale gas development. However, the influence mechanisms of gas adsorption capacity and the second adsorption layer in nanoscale pores are very complex, and are difficult to ...

Theory, Simulation and Nanotechnological Applications of Adsorption on a Surface with Defects [PDF]

open access: yes, 1998
Theory of adsorption on a surface with nanolocal defects is proposed. Two efficacy parameters of surface modification for nanotechnological purposes are introduced, where the modification is a creation of nanolocal artificial defects. The first parameter
