MS Penetrant Loading

Molecular dynamics (MD) modeling for predicting water loading and small molecule gas adsorption capacity of a condensed system

Materials Science: Penetrant Loading


MS Penetrant Loading allows simulations of the loading of a condensed system such as a polymer, zeolite, or molecular solid by a small rigid molecule, such as water or methane. The calculation provides a measure of the hygroscopicity or loading capacity of the condensed phase. It runs Grand Canonical Monte Carlo (GCMC) simulations in Desmond, allowing for the combination of Monte Carlo and molecular dynamics (MD) for substrate relaxation. This results in more realistic loading while allowing for the quick screening of materials for equilibrium adsorption.
