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.
Researchers at Oak Ridge National Laboratory have been honored with eight awards in the annual R&D 100 Awards by R&D Magazine. Sometimes referred to as the "Academy Awards of Science," the magazine selected winners for development of "one of the 100 most technologically significant new produ...
Using ever-growing genome data, scientists with the Department of Energy's (DOE) Oak Ridge National Laboratory and the University of Tennessee are tracing the evolution of the bacterial regulatory system that controls cellular motility
By applying advanced data mining techniques to observed and model-simulated climate data, a researcher at Oak Ridge National Laboratory envisions the creation of a new set of tools that can provide valuable insights into climate science. Ultimately, Karsten Steinhaeuser believes this work will lead ...
People recovering from injuries, the elderly and even athletes could one day benefit from a gait analysis technology being developed by a team at Oak Ridge National Laboratory. The patented system uses electrical signature analysis to measure, interpret and record the current drawn by a treadmill as...
A National Academies Keck Futures Initiative award of $100,000 will help researchers from Oak Ridge National Laboratory and State University of New York in their quest to create a yeast strain to produce biofuels. ORNL's Miguel Fuentes-Cabrera and SUNY's Qing Lin are looking at exporting two bacteri...
Scientists at the Department of Energy's Oak Ridge National Laboratory are planning a large-scale, long-term ecosystem experiment to test the effects of global warming on the icy layers of arctic permafrost.
With the signing of a memorandum of agreement, the Oak Ridge Reservation officially becomes one of 20 planned core ecological observatory sites that will provide valuable information to help scientists better understand how the ecosystem breathes.
ORNL's record in using small businesses to meet subcontracting needs has earned UT-Battelle the 2010 Dwight D. Eisenhower Award for Excellence in the Research and Development category.
With a network of more than 5,000 sensors that monitor weather conditions, seismic activity, traffic, bacteria on beaches, water levels and much more, Sensorpedia is a significant resource that continues to expand. Sensorpedia, developed three years ago by Oak Ridge National Laboratory's Bryan Gorma...
