The cornerstone technology to turn this concept into reality is the selectively permeable membrane
, which scientists are developing and testing at the U.
Through the process of selective transport -- the diffusion of water across a selectively permeable membrane
-- this membrane allows sweat evaporation and body heat to escape to keep wearers cooler while blocking harmful agents from entering the suit.
The research and development lab has been looking into selectively permeable membranes
, which would allow heat to escape while keeping harmful gasses out.
Those efforts have, however, led to the discovery of structurally exciting molecules that might serve as ingredients for new materials, such as selectively permeable membranes
for filtering gases from liquids, or for very hard materials of remarkably low weight, Chapman told SCIENCE NEWS.
We can see progress reported in touch-screen technology, down-well oil drilling lubricants, printable inks with security tagging, electrodes in lithium-ion batteries and selectively permeable membranes
for filtration systems.
Highly permeable membranes
tend to be less selective than less permeable membranes

Thirty-nanometer-diameter fluid ports or permeable membranes
transfer the fuel and waste products.
Baurmeister served in various senior research and development, marketing and business development roles at Membrana GmbH, a leading supplier of semi- permeable membranes
for dialysis and water purification, and its parent companies, Akzo Nobel and Acordis AG.
He has co-authored 3 books, the most recent in 1997 entitled A First Course in Ion Permeable Membranes
Employing specially designed heat permeable membranes
, Distech has produced a cost-efficient system that delivers high-purity water in commercial quantities.
