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...
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...
ORNL will lend computational resources such as its Titan supercomputer to support the Cancer Moonshot effort.

The Department of Energy’s Oak Ridge National Laboratory will add its computational know-how to the battle against cancer through several new projects recently announced at the White House Cancer Moonshot Summit.

While trying to fatten the atom in 1938, German chemist Otto Hahn accidentally split it instead. This surprising discovery put modern science on the fast track to the atomic age and to the realization of technologies with profound potential for great harm or great help. Altho...

The image above shows the chain of the studied calcium isotopes. The “doubly magic” isotopes with mass numbers 40 (Ca-40) and 48 (Ca-48) exhibit equal charge radii. The first measurement of the charge radius in Ca-52 yielded an unexpectedly large result.

For decades nuclear physicists have tried to learn more about which elements, or their various isotopes, are “magic.” This is not to say that they display supernatural powers. Magic atomic nuclei are composed of “magic” numbers of protons and neutrons—collectively called nucleons—such as 2, 8, 20, and 28.

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.

Fernanda Foertter, a user support specialist at the Department of Energy’s Oak Ridge National Laboratory, considers herself a tinkerer. Foertter’s tinkering started when she was a child, but her innate inquisitiveness still influences her work at the Oak Ridge Leadership Computing...
An illustration of the dopamine transporter in its outward- (left) and inward-opening (right) state. Note that the inward opening has brought about an outward closing and change in the number of water molecules (blue, pink spheres) inside and outside the

In an era of instant communication, perhaps no message-passing system is more underappreciated than the human body. Underlying each movement, each mood, each sight, sound, or smell, an army of specialized cells called neurons relays signals that register in the brain and connect us to our environment.

A simulation of combustion within two adjacent gas turbine combustors. GE researchers are incorporating advanced combustion modeling and simulation into product testing after developing a breakthrough methodology on the OLCF’s Titan supercomputer.

In the United States, the use of natural gas for electricity generation continues to grow. The driving forces behind this development? A boom in domestic natural gas production, historically low prices, and increased scrutiny over fossil fuels’ carbon emissions. Though coal still acco...

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 ...
