Scanning probe microscopes use an atom-sharp tip—only a few nanometers thick—to image materials on a nanometer length scale. The probe tip, invisible to the eye, is attached to a cantilever (pictured) that moves across material surfaces like the tone arm on a record player.

Researchers at ORNL have developed a quantum chemistry simulation benchmark to evaluate the performance of quantum devices and guide the development of applications for future quantum computers.

An Oak Ridge National Laboratory-led research team used a sophisticated X-ray scattering technique to visualize and quantify the movement of water molecules in space and time, which provides new insights that may open pathways for liquid-based electronics
A novel approach to studying the viscosity of water has revealed new insights about the behavior of water molecules and may open pathways for liquid-based electronics.
Fidget spinner
One drop of liquid, a cutting-edge laser 3D-printer and a few hours are all it takes to make a fidget spinner smaller than the width of a human hair. The tiny whirligig was created by researchers at Oak Ridge National Laboratory’s Center for Nanophase Materials Sciences to illustrate the facility’s unique resources and expertise available to scientists across the world.
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.”
How perovskite catalysts are made and treated changes their surface compositions and ultimate product yields. If certain perovskite catalysts of the formula ABO3 are heat-treated, the catalyst’s surface terminates predominantly with A (a rare-earth metal

For some crystalline catalysts, what you see on the surface is not always what you get in the bulk, according to two studies led by the Department of Energy’s Oak Ridge National Laboratory. The investigators discovered that treating a complex

A new method that precisely measures the mysterious behavior and magnetic properties of electrons flowing across the surface of quantum materials could open a path to next-generation electronics. A team of scientists has developed an innovative microscopy technique to detect the spin of electrons in topological insulators, a new kind of quantum material that could be used in applications such as spintronics and quantum computing.
