January 2007 (Seattle, WA) - Water security has become a national priority following the terrorist attacks of September 11, 2001. EPA has awarded Isotron a contract to develop a novel water treatment that will mitigate the threat of radionuclide contamination, such as that resulting from a terrorist release of radioactive material into the water supply. This technology is further expected to result in technology that is broadly applicable to other waterborne contaminants.

November, 2006 (Seattle, WA) – Isotron announces an effort to demonstrate the use of a new class of proton exchange membranes for use in large-scale, hydrogen production. The effort will involve the definition of the cost-effective performance targets for commercial-scale deployment of the Hybrid Sulfur (HyS) Cycle (also known as the Westinghouse Sulfur Cycle) for production of hydrogen ancillary to nuclear power plant operation. In order to achieve cost effective hydrogen production in this scenario, this team is demonstrating a novel class of membrane electrodes, which have demonstrated improved power density and reduced methanol crossover versus Nafion® PEMDMFCs. It is anticipated that these inorganic membrane electrodes will also exhibit reduced acid crossover in the proposed application. Their construction affords potential operation at temperatures up to 400oC in concentrated solutions of sulfuric acid without degradation in performance, and will therefore accept hotter feeds from the thermochemical SO2 extraction process. A cost and thermochemical model of the HyS process will be developed in order to simulate performance targets and derive a specification for the components of an effective, commercial-scale HyS plant.

Ghost Town Busters: After a dirty-bomb attack, special formulations could counter radioactive contamination
by Peter Weiss

“During a simulated dirty-bomb attack staged in Seattle in the spring of 2003, "one of the lessons learned was that [responders] had nothing to stop the spread of radioactive dust," Brethauer says.

"The first step has to be to prevent further migration" of the bomb's fallout, agrees chemical engineer Robert C. Moore of Sandia National Laboratories in Albuquerque. Immobilizing radioactive material may also enable rescue workers to do their job without becoming contaminated.
To meet those needs, researchers have been devising sticky coatings that can be sprayed from trucks and robotic sprayers or applied as paint is. The coatings have to adhere even in foul weather, maintain their integrity as vehicles roll across them, be environmentally benign, and, ultimately, be easy to remove.

Fixatives developed in the past were designed for use only on a small scale and in controlled environments, such as inside the containment building for a nuclear-power reactor, notes physicist Christina A. Lomasney, who heads the Seattle-based company Isotron Advanced Polymer Composites.

At the request of TSWG, Isotron has just developed a polymer coating that might be valuable after a dirty-bomb attack. Tests earlier this year confirmed that firefighters using standard equipment could add the material to water rushing through their hoses, just as they now add foaming agents to more effectively smother fires.”

Isotron Featured in Washington CEO Nanotechnology Special Report
Tuesday, October 11 2005
Isotron was featured in Washington CEO magazine’s Special Report on Nanotechnology this month. The October edition describes leading edge research projects and companies that are using nanotechnology in revolutionary ways and in novel applications. Isotron was specifically called out in the report for the Company’s use of a “bottom-up” approach to polymer design for military protective coatings and homeland security applications. The Nanotechnology Special Report can be found on the Washington CEO website at http://www.washingtonceo.com.
