In this artist’s conception of the process, an automated deposition system places a new material onto a base material (purple beam, right) as the last sample that was made is analyzed and sent to the AI (green beams, brain, left). The AI tells the pulsed laser deposition machine what to do next (data cable, bottom).

Neutrons — Crustacean-inspired cotton

Textile engineering researchers from North Carolina State University used neutrons at Oak Ridge National Laboratory to identify a special wicking mechanism in a type of cotton yarn that allows the fibers to control the flow of liquid across certain strands.

ORNL researchers used neutrons at the lab’s Spallation Neutron Source to analyze modified high-entropy metal alloys with enhanced strength and ductility, or the ability to stretch, under high-stress without failing. Credit: Rui Feng/ORNL, U.S. Dept. of Energy

Neutrons – ‘Stretchier’ alloys

Researchers at Oak Ridge National Laboratory have developed a method of adding nanostructures to high-entropy metal alloys, or HEAs, that enhance both strength and ductility, which is the ability to deform or stretch

Neutrons – Space ice, un-Earthly cold

Researchers from NASA’s Jet Propulsion Laboratory and Oak Ridge National Laboratory successfully created amorphous ice, similar to ice in interstellar space and on icy worlds in our solar system. They documented that its disordered atomic behavior is unlike any ice on Earth.

Neutrons—Making sustainable biofuels

Scientists at Oak Ridge National Laboratory are using neutrons to understand why certain hydrocarbons produced by blue-green algae are important to their biology, so new strains can be engineered to sustainably produce biofuels. Neutron scattering makes it possible to non-destructively see inside living algae at real world temperatures and in real time.

Neutrons—On the down-low

An Oak Ridge National Laboratory-led team has observed how a prolific class of antibiotics may be losing its effectiveness as certain bacteria develop drug resistance by acquiring enzymes known as aminoglycoside modifying enzymes. Aminoglycosides are commonly used in antibiotics to tre...
