New research about the transfer of heat—fundamental to all materials—suggests that in thermal insulators, heat is conveyed by atomic vibrations and by random hopping of energy from atom to atom.
A discovery by scientists at the Department of Energy’s Oak Ridge National Laboratory supports a century-old theory by Albert Einstein that explains how heat moves through everything from travel mugs to engine parts.

Researchers at the Department of Energy’s Oak Ridge National Laboratory made the first observations of waves of atomic rearrangements, known as phasons, propagating supersonically through a vibrating crystal lattice—a discovery that may dramatically improve heat transp...
Nanoscale spikes of carbon help catalyze a reaction that generates ammonia from nitrogen and water.
The search for a more energy efficient and environmentally friendly method of ammonia production for fertilizer has led to the discovery of a new type of catalytic reaction. Researchers at the Department of Energy’s Oak Ridge National Laboratory used nanoscale spike...
Neutron interactions revealed the orthorhombic structure of the hybrid perovskite stabilized by the strong hydrogen bonds between the nitrogen substituent of the methylammonium cations and the bromides on the corner-linked PbBr6 octahedra.
Neutron scattering has revealed, in real time, the fundamental mechanisms behind the conversion of sunlight into energy in hybrid perovskite materials. A better understanding of this behavior will enable manufacturers to design solar cells with increased efficiency...

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.
