Ionic conduction involves the movement of ions from one location to another inside a material. The ions travel through point defects, which are irregularities in the otherwise consistent arrangement of atoms known as the crystal lattice.
Lightweight powertrain materials could play a hefty role in helping automakers meet stricter Corporate Average Fuel Economy standards, and Oak Ridge National Laboratory’s supercomputer could accelerate their deployment.
Moving rods of spent nuclear fuel (SNF) to interim storage or a geologic repository requires road or rail travel.
For more than 50 years, scientists have debated what turns particular oxide insulators, in which electrons barely move, into metals, in which electrons flow freely.
