New chemical process can separate, manipulate carbon nanotubes
...ter manipulating the nanotubes, the scientists can remove the chemical handles by applying heat. The thermal treatment also restores the pristine electronic structure of the nanotubes. "Until now, the consensus has been that the chemistry of a nanotube is dependent only on its diameter, with smaller tubes ...Fe-TAML(R) activators developed at Carnegie Mellon decontaminate anthrax simulant
... water-borne anthrax, could be used in solution to remove anthrax spores from water supplies. In the future, this technology could possibly be used to clean surfaces contaminated with anthrax. Potential military uses of Fe-TAML activators and hydrogen peroxide could extend beyond killing deadly biological ...UGA researchers use transgenic trees to help clean up toxic waste site
