2008 NOV 24 - (VerticalNews.com) -- According to recent research published in the journal Advanced Materials, "Surface-functionalised graphene oxide nanosheets are obtained from substoichiometric oxidation of graphite, exfoliation, and in situfunctionalization."

  "Subsequent deoxidation produces zero-gap imperfect graphenites with carrier mobilities of 10 cm(2) V-1 s(-1). These nanosheets exhibit trap-free band-like activation energies at low temperatures for electrons and holes," wrote S. Wang and colleagues, National University ...read more

  2008 NOV 24 - (VerticalNews.com) -- According to recent research published in the journal Advanced Materials, "Coating of quantum dots (QDs), derived from both aqueous synthesis and organometallic routes, with a crosslinked peptide sheath via mimicking phytochelatin-coated heavy metal nanoclusters in plant cells is reported."

  "This coating greatly improves the stability of QDs, while maintaining their optical properties. Coated QDs contain carboxylate and amine groups for facile conjugation with various bioprobes," wrote Y.G. Zheng and colleagues ...read more

  2008 NOV 24 - (VerticalNews.com) -- According to a study from Helsinki, Finland, "Dropping in. Chemically modified silicon nanograss combines nanoscale topography with lithographically defined chemical patterns."

  "The material exhibits a high wettability gradient that allows tailoring of complex droplet shapes. The oxidized nanograss is completely wetting, while the polymer-coated nanograss has a contact angle of ca. 170 degrees and is ultrahydrophobic," wrote V. Jokinen and colleagues, Helsinki University ...read more
