Rice University physicists find reversible way to alter VO2“²s unique electronic about-face If you are not a condensed matter physicist, vanadium oxide (VO2) may be the coolest material you´ve never heard of. It´s a metal. It´s an insulator. It´s a window coating and an optical switch. And thanks to a new study by physicists at Rice University, scientists have a new way to reversibly alter VO2“²s electronic properties by treating it with one of the...

Astatine is a radioactive chemical element. The symbol for Astatine is At and its atomic number is 85. Astatine is the heaviest halogen discovered. It was first produced by Dale R. Corson, Kenneth Ross Mackenzie, and Emilio Segrè in 1940. Although astatine is produced by radioactive decay in nature, it is typically found only in miniscule amounts due to its short half-life (the time it takes for one half of the atoms of a given radioactive substance to decay or disintegrate). Trace amounts...
