RJ Lee Group has signed an agreement to license an invention developed at the Department of Energy’s Oak Ridge National Laboratory that converts waste rubber into a valuable energy storage material.
The technology turns rubber sources such as tires into c

The efficiency of solar cells depends on precise engineering of polymers that assemble into films 1,000 times thinner than a human hair.
Today, formation of that polymer assembly requires solvents that can harm the environment, but scientists at the Depar

Electron microscopy at the Department of Energy’s Oak Ridge National Laboratory is pointing researchers closer to the development of ultra-thin materials that transfer electrons with no resistance at relatively high temperatures.
The study delivers direct
