The cornerstone technology to turn this concept into reality is the selectively permeable membrane
, which scientists are developing and testing at the U.
To date, permeable membrane
based desiccant cooling systems are in the research and development phase.
The company also offers Nexar polymers featuring selectively permeable membranes
and coatings that are said to provide a unique solution that addresses the needs of textile innovators for high performance and breathable fabrics.
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.
dagger][dagger]) There is a possibility that with the recently available fully adhered vapor permeable membranes
replacing fully adhered vapor impermeable membranes under tile roofs in places such a Miami and Ft.
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.
The contributors also explore key challenges for infrastructure development, a photo-electrochemical reactor for converting carbon dioxide into methanol, group 5 metal-based hydrogen permeable membranes
, chemical methods for hydrogen storage, fuel cell technology, hydrogen-fueled vehicles, and impacts on the environment.
Electrodeionization uses semi permeable membranes
and ion exchange resins that are continuously regenerated by an electric field.
Highly permeable membranes
tend to be less selective than less permeable membranes
