A scientific team led by the Department of Energy’s Oak Ridge National Laboratory has found a new way to take the local temperature of a material from an area about a billionth of a meter wide, or approximately 100,000 times thinner than a human hair. This discove...

A new method to produce large, monolayer single-crystal-like graphene films more than a foot long relies on harnessing a “survival of the fittest” competition among crystals. The novel technique, developed by a team led by Oak Ridge National Laboratory, may open new opportunities for growing the high-quality two-dimensional materials necessary for long-awaited practical applications.

For some crystalline catalysts, what you see on the surface is not always what you get in the bulk, according to two studies led by the Department of Energy’s Oak Ridge National Laboratory. The investigators discovered that treating a complex
