"For electric conductivity, you need electrons to move
through a material," says Wally Cordes, a professor of chemistry and
biochemistry at the University of Arkansas. Cordes and his colleagues are
creating non-metal materials that conduct electricity. They bombard molecules
containing nitrogen-sulfur free radicals with X-rays in a process called x-ray
crystallography. The nitrogen sulfur free radicals have an unpaired electron
that provides the electrical conductivity. Electrons move from one molecule to
the next, but the material remains stable. Cordes is conducting ongoing research
for determining the optimum structure for electric conductivity. Contact Cordes
