Speeding Up Chemical Reactions

Using the now-decommissioned Summit supercomputer, researchers at the Department of Energy’s Oak Ridge National Laboratory ran the largest and most accurate molecular dynamics simulations yet of the interface between water and air during a chemical reaction. The simulations have uncovered how water controls such chemical reactions by dynamically coupling with…

Journey to the Center of a Neutron Star

For astrophysicists, neutron stars stand out as objects of irresistible fascination — perhaps, in part, because of how difficult they are to decipher. But calculations conducted on the Frontier supercomputer, located at the Department of Energy’s Oak Ridge National Laboratory, have revealed new clues about the inner workings of neutron…

A Cleaner Vision

Anyone who’s ever lathered up knows the dilemma. The same qualities that make surfactants — the chemical compounds in soaps, shampoos and detergents that penetrate grease, dissolve stains and make those satisfying suds in the shower — so effective as cleaners can also act as irritants. When splashed in the…

Reining in Runaway Electrons

At temperatures hotter than the sun, even a small disruption can interfere with a fusion reaction. Scientists planning for the operations of ITER, an international fusion plant now under assembly, needed to solve the problem of runaway electrons, negatively charged particles in the soup of matter in the plasma within…
