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

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...

A new study sheds light on a unique enzyme that could provide an eco-friendly treatment for chlorite-contaminated water supplies and improve water quality worldwide. An international team of researchers led by Christian Obinger from the University of Vienna used neutron analys...

Rose Ruther

In the quest for better batteries, Rose Ruther has found that the positives nearly always outweigh the negatives, and that’s what keeps her coming back to the lab. Ruther works on novel materials to create batteries with higher energy density at a lower cost as part of the Roll to Roll Manufactur...

Bacteria containing enzymes called beta-lactamases, illustrated by the light blue cluster, break down antibiotics and allow bacterial infections to develop and spread through human cells (orange). A team from ORNL’s Neutron Sciences Directorate is using n
The discovery of penicillin almost 90 years ago ushered in the age of modern antibiotics, but the growth of antibiotic resistance means bacterial infections like pneumonia and tuberculosis are becoming more difficult to treat.

Massive offshore structures like oil rigs and wind turbines are designed to withstand the myriad punishments oceans tend to mete out. However, over time, just the saltwater itself can significantly decrease the durability of a structure’s welds. That’s why professors Michael Jo...
