Polycrystalline silicalite-1 layers: texture and kinetics of growth
Self-supporting silicalite-1 layers were grown on mercury surface from clear solutions at temperatures 140-180oC. Synthesis time was varied. Kinetics of layer growth was measured and the corresponding apparent activation energy was estimated to 52kJ/...

Influence of Capillary Condensation Effects on Mass Transport through Porous Membranes.
The results indicate the occurrence of capillary condensation at a reduced pressure P/P0 of approximately 0.8 for all three gases. There is a good agreement between the volume of condensate at saturation and the pore volume determined in independent ...

Dynamic Desorption of Adsorbing Species under Cross Membrane Pressure Difference: a New Defect Characterisation Approach in Zeolite Membranes.
Making zeolite membranes able to separate gas molecules has been a goal of many authors in the last two decades. Zeolite membranes usually have a polycrystalline structure. Permeating molecules can pass through both zeolite pores (intracrystalline pa...
