This model is particularly useful for microporous carbon materials. The reported pore
size range is from 3.5 to 250 angstroms.

Method:
Model isotherms were calculated using the same methods and assumptions that were used in
the model above except in this model, the aspect ratio is equal to 12.
These two finite pore models may be used as a research tool in conjunction with independent
analytical techniques such as high-resolution transmission electron microscopy (HRTEM)
and/or X-ray diffraction (XRD) to obtain comprehensive information about the structure of
studied carbon material

Method:
Model isotherms were calculated using the prescriptions of Tarazona for density dependent
weighting functions and cylindrical pore geometry. The pore wall potential is described by
the Lennard-Jones potential of interaction between a gas molecule and the graphitic surface
of an infinitely long cylinder.
This model is particularly useful for characterizing carbon single-wall nanotubes. The
reported pore size range is from 3.5 to 1000 angstroms.
