Neutrons probed two mechanisms proposed to explain what happens when hydrogen gas flows over a cerium oxide (CeO2) catalyst that has been heated in an experimental chamber to different temperatures to change its oxidation state. The first mechanism sugges
Having the right tool for the job enabled scientists at the Department of Energy’s Oak Ridge National Laboratory and their collaborators to discover that a workhorse catalyst of vehicle exhaust systems—an “oxygen sponge” that can soak up oxygen from air and store it for later use in oxidation reactions—may also be a “hydrogen sponge.”

Oak Ridge National Laboratory researcher Ho Nyung Lee regards his research in novel materials as a “career hobby.”
Some hobbies, like woodworking, require a careful eye for planning and construction. Others, like building a ship in a bottle, need a steady hand and utmost precision.

Inspired by her computer science studies and the possibilities of 3D-printing, intern Elizabeth Yeoh-Wang found a way to combine those pursuits as she worked on a software project at the Manufacturing Demonstration Facility (MDF) at Oak Ridge National Laboratory (ORNL) last summer. Elizabeth, a r...

ORNL’s Pavel Lougovski (left) and Raphael Pooser will lead research teams working to advance quantum computing for scientific applications.
By harnessing the power of quantum mechanics, researchers hope to create quantum computers capable of simulating phenomenon at a scale and speed unthinkable on traditional architectures, an effort of great interest to agencies such as the Department of Energy tasked with tackling some of the world’s most complex science problems.
