Sigma-Aldrich to Distribute SiGNa's Alkali Metal Reagents.

St. Louis, MO-based life science and high technology company Sigma-Aldrich and New York, NY-based early advanced materials company SiGNa Chemistry recently announced that Sigma-Aldrich will distribute SiGNa's new technology for the controlled use of alkali metals, which has applications in such areas as hydrogen energy production for micro fuel cells.

According to the companies, SiGNa's patent-pending alkali metal reagents allow scientists and researchers to "dramatically" improve efficiencies and results, "bypassing traditional dangerous steps in alkali metal reduction processes."

"Encapsulating alkali metals into silica gel enables scientists who have traditionally shied away from these metals to now safely and routinely perform reductions," said Sigma-Aldrich director of business development for chemistry Chris Hewitt. "The product is expected to also stimulate the micro fuel cell sector to explore inventive uses for this easy method to generate hydrogen."
