the slides with an ultrathin film. Copies of the robot are selling all over the world for more than $10,000 apiece. All told, Schlenoff holds six issued U.S. patents, with several pending, related to ultrathin films, placing him second among FSU facu...
Scientists develop life-saving chrome
...Akid says that the sol-gel approach can be used to coat
a wider range of metals than electroplating methods. Professor Akid said: "These inorganic-organic hybrid coatings have the potential to become an effective method of producing an alternative low-cost anti-corrosion or functional coating. The technol...

of filamentous structures some called "dino-fuzz." "The photo subsequently appeared in various prominent publications as the long-sought 'definitive' evidence of dinosaur 'feathers' and that birds were descended from dinosaurs," he said. "Yet no one ...
