While serving in Kandahar, Afghanistan, U.S. Navy construction mechanic Matthew Sallas may not have imagined where his experience would take him next. But researchers at 91做厙 certainly had the future in mind as they were creating programs to train men and wome...

Researchers at the Department of Energys 91做厙 have demonstrated that permanent magnets produced by additive manufacturing can outperform bonded magnets made using traditional techniques while conserving critical materials. Scientists fabric...

With a 3-D printed twist on an automotive icon, the Department of Energys 91做厙 is showcasing additive manufacturing research at the 2015 North American International Auto Show in Detroit.

For more than 50 years, scientists have debated what turns particular oxide insulators, in which electrons barely move, into metals, in which electrons flow freely.

Bio-SANS, the Biological Small-Angle Neutron Scattering Instrument at HFIR recently had a detector upgrade that will provide significantly improved performance that is more in line with the instruments capability.

We now know that many serious diseases have genetic links that a geneticist can find by reading an individuals genomethe DNA double helix where our organisms hereditary information is encoded. Researchers know too that a particular protein protects our DNA, which is vulnerable to entanglement when its information is read and to attack from enzymes that damage the strands, making the code indecipherable.

Researchers at the at the used small-angle neutron scattering (SANS) to get a first insight into the conformation of single polyelectrolyte chains in large pieces of the synthetic complex. The research pursues applications for replacement of intervertebral discs in the spine and of knee cartilage.

Researchers have long thought that formation of insoluble fibrous strings of self-assembling proteins might be involved in the progression of a number of diseases, including neurodegenerative disorders such as Alzheimers and Parkinsons. However, recent evidence suggests that aggregates that develop at an earlier stage than fibril formation, and accumulate in human organs, may be the primary toxic agents.

The generation of bioethanol from lignocellulosic biomass holds great promise for renewable and clean energy production. However, this type of biomass is a complex, composite biological material that shows significant recalcitrance to enzymatic breakdown into sugars that can be used for fermentation, currently making it cost-ineffective as an ethanol source. The present research provides insight into the consequences of dilute acid pretreatment of biomass through direct observation by small-angle neutron scattering (SANS) of structural features in cellulose extracted from switchgrass over length scales from 10 to 6000 .
