Refrigeration keeps our food is fresh and our offices and living rooms are temperature-controlled thanks to vapor compression technology developed over a century ago, but it's reached its theoretical limit for potential energy efficiency. A group of scientists and engineers at the U.S. Department of Energy’s Ames Laboratory are inspired by the idea that refrigeration could be radically improved—made cheaper, cleaner, and more energy-efficient—by abandoning vapor compression for something entirely new: a solid-state caloric system.

Under pressure: a new experimental apparatus gathers more insight on magnetic and superconducting states11/05/2019
Producing structurally perfect graphene and other 2D materials is the secret to tapping into their potential novel electronic and spintronic properties. But how do we know when graphene, the most widely studied 2D material, is perfect-- a defect-free and uniform layer of atoms? Scientists at the U.S. Department of Energy’s Ames Laboratory have discovered an indicator that reliably demonstrates a sample’s high quality, and it was one that was hiding in plain sight for decades.
