Scientists and engineers developing more accurate approaches to analyzing nuclear power reactors have successfully tested a new suite of computer codes that closely model “neutronics” — the behavior of neutrons in a reactor core.
ORNL study uses neutron scattering, supercomputing to demystify forces at play in biofuel production
Researchers studying more effective ways to convert woody plant matter into biofuels at the Department of Energy's Oak Ridge National Laboratory have identified fundamental forces that change plant structures during pretreatment processes used in the
Gas and oil deposits in shale have no place to hide from an Oak Ridge National Laboratory technique that provides an inside look at pores and reveals structural information potentially vital to the nation’s energy needs.
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 instrument’s capability.
We now know that many serious diseases have genetic links that a geneticist can find by reading an individual’s genome─the DNA double helix where our organism’s 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 Bio-SANS instrument at the High Flux Isotope Reactor (HFIR) 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.
Imagine an instrument that collects thousands of diffraction data points in days instead of months with the help of a cylindrical image plate detector and an intense polychromatic neutron beam. IMAGINE is the newest single crystal diffractometer being installed at the High Flux Isotope Reactor, and ...
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 Alzheimer’s and Parkinson’s. 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 Å.
