Organic chemistry — leading light waves astray

June 5, 2013 – 12:00 am
  • Organic chemistry -- leading light waves astray - The cloak that renders one invisible is a common element in mythology and fairy-tales, but new materials with surprising properties bring the idea closer to reality by providing novel ways of manipulating light.(10.1021/jo4005662)

    Scientists uncover fundamental property of astatine — rarest naturally occurring element on Earth

    May 17, 2013 – 8:00 am
  • Scientists uncover fundamental property of astatine -- rarest naturally occurring element on Earth - Scientists have carried out ground-breaking experiments to investigate the atomic structure of astatine (atomic number 85), the rarest naturally occurring element on Earth. Through experiments conducted at the radioactive isotope facility ISOLDE at CERN, scientists have accessed, for the first time, the ionization potential of the astatine atom. The successful measurement fills a long-standing gap in Mendeleev's periodic table, since astatine was the last element present in nature for which this fundamental property was unknown.(10.1038/ncomms2819)

    Biobatteries catch breath

    March 9, 2013 – 5:01 am
  • Biobatteries catch breath - An air-breathing bio-battery has been constructed by researchers from Poland. The core element providing the new power source with relatively high voltage and long lifetime is a carefully designed cathode taking up oxygen from air and composed of an enzyme, carbon nanotubes and silicate.
