Sentence examples for model gas pair from inspiring English sources

In addition, the data for the aged film of PIM-EA-TB crosses the 2008 upper bound for CO2/CH4 and is comparable with the data of the best performing PIMs for this commercially important gas pair.[ 11a] According to the solution-diffusion model the permeability of a gas through a dense polymer is dependent on both its diffusivity (D x) and its solubility (S x) (i.e., P x = D xS x).

A mean transport-pore model (MTPM) is proposed which requires permeation, steady-state diffusion or pulse chromatographic measurements with several gases or gas pairs and/or at different pressures and temperatures.
