Model isotherms were calculated using the prescriptions of Tarazona for density dependent weighting
functions and a cylindrical pore geometry. The wall potential used is k = 30 K, typical for a silica or
alumina surface.
This model file is particularly useful for sizing zeolites or zeolite containing materials that have sub-
stantial micropore volume. The reported pore size range is 3.8 to 387 Å.

Model isotherms were calculated using the prescriptions of Tarazona for density dependent weighting
functions and a slit-like pore geometry. These models are slightly different from N2-DFT and Ar-DFT
models that were calculated using NLDFT with density independent weighting functions.
The reported pore size range is from 3.5 to 1000 Å.
