| Outline of Final Research Achievements |
A novel gas/isotope separator is devised by using "molecular exchange" phenomena in micro-pores found in my previous JSPS grant-in-aid (23560196). The "molecular exchange in micro-pores" means that light and heavy molecules in the gaseous mixture permeate through the micro-channels in porous membrane in the opposite direction. This study shows that it enables efficient gas mixture separation devices. The device works for any gas components since this device does not make use of chemical properties of specific gas species. The variation of the molar fraction is about 1 % per 1 cm of the membrane for gas mixture with substantial molar mass ratio. This means that a desktop gas/isotope separator that works for any gas mixture is possible by the molecular exchange phenomena. Large production rate is possible by increasing the width of the membrane. Various energy is available for the device since small temperature difference of order of 10 K is the only energy source of this device.
