Oak Ridge National Laboratory has partnered with FCA US LLC and casting manufacturer Nemak to develop a new cast aluminum alloy for engine cylinder heads, which could lead to more fuel-efficient internal combustion engines.

Materials—Polymer-theory-problem

Scientists at Oak Ridge National Laboratory have conducted a series of breakthrough experimental and computational studies that cast doubt on a 40-year-old theory describing how polymers in plastic materials behave during processing.

A tetradentate ligand selects americium (Am, depicted by green spheres) over europium (Eu, blue spheres). Red indicates oxygen atoms and purple, nitrogen atoms that are the key to the ligand’s selectivity. Image credit: Oak Ridge National Laboratory, U.S.
After used nuclear fuel is removed from a reactor, it emits heat for decades and remains radioactive for thousands of years. The used fuel is a mixture of major actinides (uranium, plutonium), fission products (mainly assorted metals, including lanthanides) and minor actinides (i.e....

Budhendra Bhaduri, a researcher at the Department of Energy's Oak Ridge National Laboratory, has been selected to receive the Anderson Medal of Honor in Applied Geography for 2018 from the American Association of Geographers (AAG) in recognition of highly distingui...

Eugene Dumitrescu, Ben Lawrie, Matthew Feldman, and Jordan Hachtel (from left) have conducted investigations aimed at controlling the dissipative nature of quantum systems and materials. The cathodoluminescence microscope used in their work appears at rig
Scientists at the Department of Energy’s Oak Ridge National Laboratory are conducting fundamental physics research that will lead to more control over mercurial quantum systems and materials. Their studies will enable advancements in quantum computing, sensing, simulation, and mater...
Researchers work on the delicate wiring of a cryostat, which is like a thermos under vacuum that chills the detectors that are the heart of the MAJORANA DEMONSTRATOR. The experiment’s 2 cryostats each house 29 germanium detectors—diodes that are reverse b
If equal amounts of matter and antimatter had formed in the Big Bang more than 13 billion years ago, one would have annihilated the other upon meeting, and today’s universe would be full of energy but no matter to form stars, planets and life. Yet matter exists now. ...
