Tomsk scientists offer nanomaterial to foil corporate espionage

Scientists in Tomsk, in Siberia, have developed a new composite coating which can be used to make special eavesdropping-free rooms for business negotiations.

Scientists at Radiozashchita-T, an innovation spin-off of Tomsk State University (TSU) in Siberia, have developed a new composite coating which can be used to make special eavesdropping-free rooms for business negotiations, Russian news agency RIA Novosti reported, citing a statement by Radiozashchita-T CEO Grigory Kuleshov. According to Mr. Kuleshov, the new material consists of microwave ferrites and carbon nanostructures in various concentrations. The coating can both absorb and reflect emission, depending on its composition. Mixing ferrites with low-concentration carbon nanostructures will produce an almost pure absorber; with higher concentrations the material will also begin reflecting emission. ?Our coating will help build ?security rooms,? frustrating those eager to poke their noses in other people?s business,? Mr. Kuleshov said. The material has wide applications, he further explained. Adding it to paint for walls would protect an apartment against radiations, which is particularly important with base mobile communications stations nearby. The material could be used to make special screens to protect a person against the radiation of his or her own cell phone...
