Ask a biofuel researcher to name the single greatest technical barrier to cost-effective ethanol, and you’re likely to receive a one-word response: lignin. Cellulosic ethanol—fuel derived from woody plants and waste biomass—has the potential to become an affordable, renew...
In pure water, lignin adopts a globular conformation (left) that aggregates on cellulose and blocks enzymes. In a THF-water cosolvent, lignin adopts coil conformations (right) that are easier to remove during pretreatment.
When the Ford Motor Company’s first automobile, the Model T, debuted in 1908, it ran on a corn-derived biofuel called ethanol, a substance Henry Ford dubbed “the fuel of the future.”
ORNL researchers are developing an idealized collector molecule that has a shape complementary to the surface atomic structure of xenotime, a rare earth yttrium-rich phosphate mineral.

Ensuring a reliable supply of rare earth elements, including four key lanthanides and yttrium, is a major goal of the Critical Materials Institute (https://cmi.ameslab.gov) as these elements are essential to many clean-energy technologies. These include energy-efficient lighting, ...

Oak Ridge National Laboratory’s Joe Giaquinto investigates chemical clues for trace-level radioactivity. Giaquinto leads ORNL’s Nuclear Analytical Chemistry and Isotopics Laboratory, which makes critical contributions to nuclear forensics and nonprolifera

A group of nuclear detectives at the Department of Energy’s Oak Ridge National Laboratory takes on tough challenges, from detecting illicit uranium using isotopic “fingerprints” to investigating Presidential assassination conspiracies. 

In a Fluid Interface Reactions, Structures and Transport Center project to probe a battery’s atomic activity during its first charging cycle, Robert Sacci and colleagues used the Spallation Neutron Source’s vibrational spectrometer to gain chemical inform

Rechargeable batteries power everything from electric vehicles to wearable gadgets, but obstacles limit the creation of sleeker, longer-lasting and more efficient power sources. Batteries produce electricity when charged atoms, known as ions, move in a circuit from a positive end ...

ORNL’s Ralph Dinwiddie uses infrared cameras to create heat maps of working materials that reveal their thermal properties and subsurface structure. This 1998 image of an aging aircraft’s engine cowling revealed severe subsurface corrosion.
Scientists at the Department of Energy’s Oak Ridge National Laboratory are pioneering the use of infrared cameras to image additive manufacturing processes in hopes of better understanding how processing conditions affect the strength, residual stresses and microstructure of ...

The Department of Energy’s Oak Ridge National Laboratory and SCIEX of Framingham, Mass., have signed a licensing agreement for technologies that speed up, simplify and expand the use of analytic chemistry equipment. SCIEX is a leading manufacturer of mass spectrome...

Drones can play an important role in a number of areas, including making the U.S. safe, improving crop yield and safeguarding the environment.

With the creation of the Unmanned Aerial Systems Research Center (http://uasresearch.ornl.gov), Oak Ridge National Laboratory makes available tools and capabilities with applications in environment, energy

New transparent conductor made from more earth-abundant elements promises lower cost solar cells and displays.
Touchscreens, smart phones, liquid crystal displays and solar panels of tomorrow could be more efficient because of a new material profiled in a paper published in Scientific Reports. Researchers at the University of Tennessee and Oak Ridge National Laboratory have demonstrated a t...
