In reality, however, mathematical, perfect or ideal geometric forms are unattainable since under microscopic examinations all real surfaces exhibit flaws. For example, if a ‘super microscope’ were available one would observe surface roughness due not only

Equally important is the cross-sectional area of each molecule or the effective area covered by each adsorbed molecule on the surface. The surface area then, is the product of the number of molecules in a completed monolayer and the effe

Whereas the scattering methods cannot be used in routine operations (to date at least), immersion calorimetry and in particular permeability measurements are more fre
