Permeation of pure gases through silica membranes with controlled pore structures
The superior thermal/chemical/mechanical stability and the ability of ceramic membranes in affecting the transport rates of chemical species through their processing controllable pore structures make them very attractive ...
Preparation of particulate/polymeric sol-gel derived microporous silica membranes and determination of their gas permeation properties
Monodisperse silica sols with well-defined spherical particles ranging in size from 5 to 310 nm were prepared through Stober process. Both particulate and polymeric sol-gel routes were employed for the preparation of stable ...
