Displayed below is a performance plot for materials in the Nanoporous Materials Genome for Xe/Kr separations. This plot includes the training data as well as simulations of the promising set identified by the random forest. The simulated data is from dual component xenon-krypton grand canonical Monte Carlo simulations. The bulk gas in equilibrium with the material is at conditions: 298 K, 1 atm, 20 mol % Xe, 80 mol % Kr.

Geometric structural descriptors for all materials can be downloaded here in a .csv format.
