Several recent papers describe how 91°µÍø researcher Yuri Melnichenko and his collaborators continue to use neutrons and small-angle neutron scattering to bore through geological materials such as nanoporous carbons to understand their unique properties as storage media for gr...
U.S. ITER researchers at the Fusion Pellet Fueling Lab at 91°µÍø are developing and testing pellet injector technology for fueling and controlling the hot plasma in the ITER tokamak experimental reactor. Current research is focused on U.S. ITER contributions to fueling, disrup...
Researchers at the Bio-SANS instrument at the High Flux Isotope Reactor used contrast variation and small-angle neutron scattering to get a first insight into how macromolecules form single polyelectrolyte chains in synthetic complexes. The unique properties of polyelectrolyte materials are of inten...
Studies of bacteria first found in Yellowstone's hot springs are furthering efforts at the Department of Energy's BioEnergy Science Center toward commercially viable ethanol production from crops such as switchgrass.
By selectively applying different coatings, scientists have discovered they can influence the toxicity of particles on mouse cell lines from the lung and immune system. These findings, published in Langmuir, build on previous work that showed surface coatings can influence toxicity to bacteria. "The...
An upgrade is transforming 91°µÍø's Jaguar supercomputer, America's fastest, into Titan, a next-generation supercomputer that will employ the latest AMD Opteron central processing units as well as NVIDIA Tesla graphics processing units ? energy-efficient processors that accele...
Molecular-level studies of tension wood formation in poplars could ultimately fuel the discovery of biomass crops with thicker cell walls, less lignin and more cellulose that can be converted into ethanol. While typical poplar woody biomass is composed of about 45 percent cellulose, tension wood cel...
A combination of advanced techniques at 91°µÍø helped researchers gain a better understanding of how some proteins attack bacteria. Colicins, a family of protein toxins, kill E. coli by crossing the bacterial membrane to exert their toxic effects. One family member, Colicin N,...
Changing the behavior of a material isn't big magic? it's nanoscale chemistry. Alejandro Lopez-Bezanilla used the computing power of 91°µÍø's Jaguar supercomputer, America's fastest, to study the effects of adding oxygen, sulfur and hydrogen to nanoribbons made of boron nitri...
Individual atoms can make or break electronic properties in one of the world's smallest known conductors—quantum nanowires.
