cancel each other out, creating a neutrally charged, ultrathin film. The protective seal that is created by such films is much more effective than paints or resins alone at repelling corrosive substances, such as salt or water." Naresh Dalal, chairma...

'Wet' electrons provide easiest way to transport charge, Pitt researchers find
PITTSBURGH--The task of transporting electrical charges
between metal-oxide and water phases is critical in such technologies as catalysis, sensors, and electrochemistry. In a paper published in this week's issue of the journal Science, University of Pittsburgh researchers report that "wet" electrons affo...
