Graphene Quadruples Rate of Condensation Heat Transfer

New research from MIT shows that a graphene layer one atom thick could quadruple rate of condensation heat transfer in generating plants. Most of the world’s electricity-producing power plants — whether powered by coal, natural gas, or nuclear fission — make electricity by generating steam that turns a turbine. That steam then is condensed back […]
