Heavy-duty vehicles contribute 23% of transportation emissions of greenhouse gases and account for almost one-quarter of the fuel consumed annually in the U.S. Credit: Chris Bair/Unsplash

Through a consortium of Department of Energy national laboratories, ORNL scientists are applying their expertise to provide solutions that enable the commercialization of emission-free hydrogen fuel cell technology for heavy-duty

Parans Paranthaman, a researcher in the Chemical Sciences Division at ORNL, coordinated research efforts to study the filter efficiency of the N95 material. His published results represent one of the first studies on polypropylene as it relates to COVID-19. Credit: ORNL/U.S. Dept. of Energy

When COVID-19 was declared a pandemic in March 2020, Oak Ridge National Laboratory’s Parans Paranthaman suddenly found himself working from home like millions of others.

ORNL researchers used electron beam powder bed fusion to produce refractory metal molybdenum, which remained crack free and dense, proving its viability for additive manufacturing applications. Credit: ORNL/U.S. Dept. of Energy

Oak Ridge National Laboratory scientists proved molybdenum titanium carbide, a refractory metal alloy that can withstand extreme temperature environments, can also be crack free and dense when produced with electron beam powder bed fusion. 

An ORNL-invented electrocatalyst made of custom-designed alloy nanoparticles embedded in carbon nanospikes was licensed by Prometheus Fuels and further developed to aid a process to convert solar and wind electricity into chemical energy for electrofuels. Credit: ORNL, U.S. Dept. of Energy

In a new twist to an existing award-winning ORNL technology, researchers have developed an electrocatalyst that enables water and carbon dioxide to be split and the atoms recombined to form higher weight hydrocarbons for gasoline, diesel and jet fuel.

ORNL researchers used fiber reinforcements made of steel, glass and carbon to develop a concrete mix that demonstrated high early strength within six hours of production, which is needed for the precast concrete industry. Credit: ORNL/U.S. Dept. of Energy

A team of researchers at Oak Ridge National Laboratory and the University of Tennessee have developed a concrete mix that demonstrated high early strength within six hours of mixing, potentially doubling the production capacity for the precast industry.

Neutron scattering experiments show electric charges, shown in red, blue and grey, in the SARS-CoV-2 main protease site where telaprevir binds to the structure.

Scientists have found new, unexpected behaviors when SARS-CoV-2 – the virus that causes COVID-19 – encounters drugs known as inhibitors, which bind to certain components of the virus and block its ability to reproduce.

The pressure cell uses two gem-quality synthetic opposing diamonds to exert extreme pressures on materials, providing fundamental insights into materials that only neutrons can reveal. Credit: Genevieve Martin/ORNL, U.S. Dept. of Energy

Researchers at Oak Ridge National Laboratory’s Spallation Neutron Source have developed a diamond anvil pressure cell that will enable high-pressure science currently not possible at any other neutron source in the world.

ORNL researchers used gas metal arc welding additive technology to print the die for a B-pillar or vertical roof support structure for a sport utility vehicle, demonstrating a 20% improvement in the cooling rate. Credit: ORNL/U.S. Dept. of Energy

A team of Oak Ridge National Laboratory researchers demonstrated that an additively manufactured hot stamping die – a tool used to create car body components – cooled faster than those produced by conventional manufacturing methods.

A new artificial membrane helps researchers understand proteins in human cell membranes. The membrane rim is made of a detergent (purple), with a center made of lipid molecules found in biological membranes (green and blue), including cholesterol (gold).

Researchers believe that proteins could behave differently in lipid raft environments, compared to non-raft regions in a membrane, but this hypothesis has not been fully evaluated. One reason is that membrane models used to study membrane proteins rarely contain rafts.
