Argonide
From Wikipedia, the free encyclopedia
Argonide is a Florida nanotechnology company. Their main product, NanoCeram, is aluminum oxide nanofibers for water filtration. The company was formed in 1994 by American Fred Tepper, partly to provide employment for former Russian (government) scientists.
Nanoceram, which can be incorporated into glass and cellulose non-woven sheets, is an extremely effective filtration medium[citation needed]. The alumina fibers, which are only 2 nanometers wide, attract dirt, bacteria, viruses and proteins using an electrostatic effect. NanoCeram can match the particle removal effectiveness of ultrafiltration, and it allows orders-of-magnitude higher flow rates (at given pressure difference or pressure drop).
Argonide has been awarded a NASA SBIR contract to filter water aboard Space Shuttles. It was "named one of the top 100 most technologically significant new products of 2002 by R&D Magazine". (See R&D 100.)
Argonide also produces "nanopowders and alloys".
