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.
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.
Adam Witt
Adam Witt’s career path has followed some twists and turns, much like the rivers he studies. But the diversity of his professional experience is a boon to his work as he looks for new ways to harness an ancient energy source: water. Witt, a hydropower systems research engineer,...
ORNL’s Michael Hu is the team lead for thermochemical processing under the DOE Bioprocessing Separations Consortium, leading scientists from eight national laboratories as they develop technologies  to reduce the cost of expensive catalysts.

Chemical and biomolecular engineer Michael Hu has spent his career devising novel means to filter, separate, and select desirable materials from liquids and gases with an eye toward better biofuels, biochemicals, pharmaceuticals, and other products—and is setting his sights on app...

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...

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...

Interdisciplinary work has been a hallmark of Julie Mitchell’s career, and it is a strength she expects to leverage in helping solve some big science challenges as she steps into the role of Deputy Director of the Biosciences Division at Oak Ridge National Laboratory (ORNL). Mitchell will support...

The interior of the Massachusetts Institute of Technology’s (MIT’s) Alcator C-Mod tokamak. A team led by Princeton Plasma Physics Laboratory’s C.S. Chang recently used the Titan supercomputer

The same fusion reactions that power the sun also occur inside a tokamak, a device that uses magnetic fields to confine and control plasmas of 100-plus million degrees. Under extreme temperatures and pressure, hydrogen atoms can fuse together, creating new helium atoms and simulta...

Chengyun Hua applied for a Liane B. Russell Distinguished Early Career Fellowship after meeting ORNL researchers at a Society of Women Engineers conference.

In Chengyun Hua’s research, everything revolves around heat and how it moves. As a Russell Fellow at the Department of Energy's Oak Ridge National Laboratory, Hua carefully analyzes nanoscale heat transfer mechanisms using laser spectroscopy. “Heat is being generated from every...

An image of a complete 7HA.02 gas turbine. The new GE turbine is capable of achieving an overall efficiency of more than 62 percent in a combined-cycle power plant and is projected to exceed world-record efficiency marks set by GE’s 9HA turbine model.
In 2017, US-based General Electric (GE) delivered its newest heavy-duty gas turbine, the 7HA.02, to two power plants in Texas. The installations marked a milestone in natural gas–derived electricity generation, setting new marks in efficiency and emissions for utility-scale turboma...
