Driving membrane curvature

In biological systems, membranes are as important as water. They form the barrier between the inner world, within our cells, where we perform the chemical reactions of life, and the outside environment.

DOE lab that pioneered electric vehicles sets sights on natural gas cars, trucks

Platts Inside Energy—The Energy Department national laboratory that brought cutting-edge battery technology to the Chevrolet Volt and other hybrid-electric vehicles now hopes to be the vanguard of another automotive power source that many say is poised to grab a big share of the transportation-fuel market: natural gas.

U.S. Department of Energy Secretary Stephen Chu presented the 2012 Secretary’s Achievement Award to Argonne Environmental Engineer Greg Barrett for the Fugitive Emissions Working Group’s exceptional SF6 recovery efforts.
Argonne recognized by Energy Secretary Chu for greenhouse gas reductions

Argonne National Laboratory is leading the way in greenhouse gas reductions, particularly with the recapture and recycling of sulfur hexafluoride (SF6). SF6 is a gas used in industry as an anti-arcing agent. It is an extremely potent greenhouse gas — one pound of SF6 is equivalent to 12 tons of carbon dioxide.

Shedding new light on LEDs

LEDs, or light-emitting diodes, are the secret behind your iPhone screen, flatscreen TVs, Christmas lights and crosswalk signals. They can last longer and save more energy than traditional incandescent bulbs. But there is one thing they aren’t very good at: efficiently emitting light in the yellow-green spectrum.

Finding functionals for fission

Understanding of the fission process is crucial for many areas of science and technology—for example, for deploying safe and efficient advanced nuclear reactors. Accurately estimating the stability of a heavy nucleus against fission in its ground state is, however, a complex mathematical problem involving hundreds of strongly interacting protons and neutrons moving in a splitting nucleus.

Unconventional topological spin structure in coupled magnetic discs

Argonne's Materials Science Division researchers have fabricated an artificially-confined system of magnetic discs coupled antiferromagnetically through a spacer layer, and demonstrated for the first time that this system forms an unconventional topological spin structure.

Scientists at Argonne's Advanced Photon Source investigated nanoscale confinement on the local viscosity of entangled polystyrene films at high temperatures.
Peering into the interfaces of nanoscale polymeric materials

The development of polymer nanostructures and nano-devices for a wide variety of applications could emerge from new information about the interplay between nanoscale interfaces in polymeric materials.

New Process for Synthesizing Robust Catalysts

The two main routes for the deactivation of catalysts consisting of metal nanoparticles are coking (the accumulation of carbon on the metal that blocks the catalytic sites) and sintering (the formation of larger metal particles that lowers the activity).
