Scientists from Oak Ridge National Laboratory used high-performance computing to create protein models that helped reveal how the outer membrane is tethered to the cell membrane in certain bacteria.

Simulation of short polymer chains

Oak Ridge National Laboratory scientists have discovered a cost-effective way to significantly improve the mechanical performance of common polymer nanocomposite materials.

Computing – Mining for COVID-19 connections

Scientists have tapped the immense power of the Summit supercomputer at Oak Ridge National Laboratory to comb through millions of medical journal articles to identify potential vaccines, drugs and effective measures that could suppress or stop the

A new computational approach by ORNL can more quickly scan large-scale satellite images, such as these of Puerto Rico, for more accurate mapping of complex infrastructure like buildings. Credit: Maxar Technologies and Dalton Lunga/Oak Ridge National Laboratory, U.S. Dept. of Energy

A novel approach developed by scientists at ORNL can scan massive datasets of large-scale satellite images to more accurately map infrastructure – such as buildings and roads – in hours versus days.

Since the discovery of high-temperature superconductors — materials that can transport electricity with perfect efficiency at or near liquid nitrogen temperatures (minus-196 degrees Celsius) — scientists have been working to develop a theory that explains their essential physics.
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 that are easier to remove during pretreatment. (ORNL image)
Breaking down cellulosic biomass for biofuel is a costly and complex process, requiring lots of acid, water, and heat. Experimental pretreatments, however, hold the promise of driving down these costs by making more biomass available to enzymes for fermentation. To gain a better...
