In this work, we study films of silicalite crystals used in gas separation processes. These crystals were obtained by hydrothermal synthesis during different times and using different gel composition. They were deposited on an alumina support growing

Atomic Force Microscopy (AFM), a recently developed technique, has proved to be a specially useful tool to characterise different types of material surfaces. In this work, we have used AFM to achieve a complete surface characterisation of several mic

In this work, it has been studied the influence of the particles size and sinterization temperature in the preparation of flat microfiltration ceramic membranes. These membranes were made from ceramic materials by controlling, among other factors, th

Among the separation processes in the industry, those using membranes are usually considered as forming a new and promising field. From them, those which use ceramic membranes, which can be manufactured more selective now than some time ago, are espe

The relationships between gas permeability and free volume fraction, intersegmental distance, and glass transition temperature, are investigated. They are analyzed for He, CO2, O2, CH4, and N2 gases and for five similar polyimides with a wide range o
