A precision approach to treating snow- and ice-covered roads, developed by an Oak Ridge National Laboratory-led research team, aims to help cities effectively allocate resources and expand coverage on roadways. The combined software and hardware technology analyzes existing city data and uses high-resolution modeling to identify areas most vulnerable to drivers during hazardous weather conditions.

An Oak Ridge National Laboratory-led team discovered a function of certain microbes that produces a new derivative of vitamin B12, which is crucial to a cell’s ability to perform life-sustaining metabolic activities. Their findings could ultimately open avenues for novel environmental and water clean-up strategies.

A multi-laboratory research team led by Oak Ridge National Laboratory used neutrons, x-rays and computational modeling to “see” the atomic structures inside a new class of aluminum-cerium alloys created for automotive and aerospace applications.
ORNL’s Larry Allard used high-resolution aberration-corrected electron microscopy methods to image single atoms of rhodium in a zeolite catalyst material, which aided in the development of a breakthrough process that directly converts methane to methanol.
MEDFORD/SOMERVILLE – The direct oxidation of methane—found in natural gas—into methanol at low temperatures has long been a holy grail. Now, researchers at Tufts have found a breakthrough way to accomplish the feat using a heterogeneous catalyst and cheap molecular oxygen, according to a paper published today in the journal Nature by a team led by Tufts University chemical engineers.

Photosynthesis is one of the most important processes on Earth. Without it the food chain would collapse, and we would lose a primary source of oxygen for all life. Yet it is a process that is still poorly understood outside the laboratory. With the help of an Oak Ridge Nation...
Scientists peer inside materials used to clean automotive exhaust to understand why one works better than the other. Red and blue dots represent positions of copper and aluminum atoms, respectively, for two zeolite catalysts (SSZ-13 and ZSM-5) used in a d

Diesel vehicles today emit far fewer pollutants than older vehicles, thanks to a zeolite (hydrous silicate) catalytic converter that was invented around 10 years ago to reduce pollutants that cause the formation of acid rain and smog. Although many groups have investigated t...

Inspired by the brain’s web of neurons, deep neural networks consist of thousands or millions of simple computational units.

Deep neural networks—a form of artificial intelligence—have demonstrated mastery of tasks once thought uniquely human. Their triumphs have ranged from identifying animals in images, to recognizing human speech, to winning complex strategy games, among other su...

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.

David Weston became fascinated with plant genetics and ecology in college, and now with the support provided by the DOE Office of Science Early Career Research Program, he will link those fields as he studies plant-microbe symbiosis. The research will focus on sphagnum moss, a dominant plant of n...
