Rice U. scientists find simple method for producing dots in
bulk from coal, coke
The prospect of turning coal into fluorescent particles may
sound too good to be true, but the possibility exists, thanks to scientists at
Rice University.
The Rice lab of chemist James Tour found simple methods to
reduce three kinds of coal into graphene quantum dots (GQDs), microscopic discs
of atom-thick graphene oxide that could be used in medical imaging as well as
sensing, electronic and photovoltaic applications.
