An international team of scientists have discovered a transparent form of the element sodium (Na). The team, led by Artem Oganov, Professor of Theoretical Crystallography at Stony Brook University, and Yanming Ma, the lead author and professor of physics at Jilin University in China, was able to demonstrate that sodium defies normal physical expectations by going transparent under pressure. The results are published in the March 12 edition of the journal Nature. http://phys.org/news156104532.html Physics Thu, 12 Mar 2009 19:22:47 EST news156104532
