The researchers describe tests of their process on almost a half-ton of scrap PCBs, which showed that it is efficient and environmentally friendly. The technology involves special crushing of scrap PCBs, followed by separation of the metallic and non-metallic materials with an electric field. The technique has advantages over other methods proposed for recycling PCBs, the researchers indicate.

Unraveling a molecular machine's mysteries
Chemical & Engineering News
Research on one of the most important molecular "machines" in living cells is giving scientists clues to the development of new antibiotics and revealing secrets about how cells use the genetic information encoded in DNA, according to an article scheduled for the Feb. 19 issue of Chemical & Engineering News (C&EN), ACS' weekly newsmagazine.
In the article, C&EN senior correspondent Stuart A. Borman explains that ribosomes translate DNA's message, encoded on messenger RNA (mRNA), and use it to synthesize thousa
