Abstract

Small angle neutron scattering data of Vycor is analyzed using a chord distribution model describing the microporous structure. In addition, the same model is applied in interpreting the data taken when capillary condensation takes place in the porous medium. In both cases, the results are in good agreement with other measurements, and shows a promising potential in describing such a bicontinuous system.

5.Form F(l) = l‘ae−bl’ has only one variable. For example, if one changes b to b', it becomes F(l) = l ae-b'l = cl ‘ae−bl’, where l '= (b'/b)l and c = (b/b')a., so that the shape of the function does not change, only the average chord length I does, which is trivial.Google Scholar
