Tracking Pileups on Battery Charging Route to Drive Performance

An understanding of this mechanism could help scientists increase the total amount of energy stored by next-generation lithium-ion batteries.

Uncovering Hidden Local States in a Quantum Material

States of local broken symmetry at high temperature—observed in several materials, including one with a metal-insulator transition, an iron-based superconductor, and an insulating mineral part of the Earth’s upper mantle—may enable the technologically relevant properties arising at much-lower temperature.
