ABSTRACT
Mesoporous solids play an important role as gas adsorbents, cat-
alysts, or porous barriers in a wide range of applications relating
to chemical, biomedical, or environmental engineering; the intelli-
gent design of which presupposes fundamental understanding of
the physical principles and mechanisms underlying the gas adsorp-
tion and permeability properties of the said solids in relation to
their structure. This in turn requires astute idealized modeling,
which aims at identifying and correlating the essential features of both physics and structure (in contradistinction to simulation, which
seeks to reproduce reality in all its complexity).
