Researchers at Penn State, the Department of Energy’s Oak Ridge National Laboratory and Lockheed Martin Space Systems Company have developed methods to control defects in two-dimensional materials, such as graphene, that may lead to improved membranes for water desalination, energy...
ORNL researcher Xiaobing Liu  works in the laboratory’s Building Technologies Research and Integration Center.

As a boy growing up in China, Xiaobing Liu knew all about Oak Ridge and the World War II Manhattan Project. He had no idea that he would one day work at DOE’s Oak Ridge National Laboratory, the Secret City’s successor. Liu is a lead researcher in geothermal heat pump (GHP) techn...

Just a few years ago, Emilio Ramirez spent his days operating and adjusting settings to optimize thermal performance at a Central California bioenergy power plant. Ramirez, a California native who is now a University of Tennessee doctoral candidate working with the Department of Energy's Oak Ridg...

Diana Hun likes ORNL's state-of-the-art facilities and range of expertise.

When Diana Hun left her home in Panama City, Panama, to attend school at the University of Texas in Austin, she knew she wanted to be an engineer. Exactly which branch of engineering to pursue was not quite as straight-forward. Hun studied both mechanical and electrical engin...

A 32-face 3-D truncated icosahedron mesh was created to test the simulation’s ability to precisely construct complex geometries.
Designing a 3-D printed structure is hard enough when the product is inches or feet in size. Imagine shrinking it smaller than a drop of water, smaller even than a human hair, until it is dwarfed by a common bacterium. This impossibly small structure can be made a reality with fo...

Sitting in the driver’s seat comes naturally to Ron Graves, the recently retired head of Oak Ridge National Laboratory’s sustainable transportation program. Graves has logged more than 100 days on national racetracks like Daytona, Road Atlanta, and Pocono where he routinely reache...

Simon Pallin

A scientist that sings opera and performs in musical theater? Sure. If you're a Renaissance Man like Simon Pallin. Pallin is a researcher in Oak Ridge National Laboratory’s Buildings Technologies Research & Integration Center. But his early interests and activities reveal a versatile person that could have chosen a number of occupations.

In conventional, low-temperature superconductivity (left), so-called Cooper pairing arises from the presence of an electron Fermi sea. In the pseudogap regime of the cuprate superconductors (right), parts of the Fermi sea are “dried out” and the charge-ca
When physicists Georg Bednorz and K. Alex Muller discovered the first high-temperature superconductors in 1986, it didn’t take much imagination to envision the potential technological benefits of harnessing such materials.
Department of Energy national lab researchers found strain dramatically influences low-temperature oxygen electrocatalysis on perovskite oxides, enhancing bifunctional activity essential for fuel cells and metal–air batteries.

Catalysts make chemical reactions more likely to occur. In most cases, a catalyst that’s good at driving chemical reactions in one direction is bad at driving reactions in the opposite direction. However, a research team led by the Department of Energy’s Oak Ridge National Laboratory ...

A 3D structure of the HIV-1 protease in cartoon representation with bound clinical drug darunavir (shown as sticks).
A team led by the Department of Energy’s Oak Ridge National Laboratory used neutron analysis to better understand a protein implicated in the replication of HIV, the retrovirus that causes AIDS. The enzyme, known as HIV-1 protease, is a key drug target for HIV and AIDS therapies. &nbs...
