Depicted at left, small nanoparticles stick to segments of polymer chain that are about the same size as the nanoparticles themselves; these interactions produce a polymer nanocomposite that is easier to process because nanoparticles move fast, quickly ma
Polymer nanocomposites mix particles billionths of a meter (nanometers, nm) in diameter with polymers, which are long molecular chains. Often used to make injection-molded products, they are common in automobiles, fire retardants, packaging materials, drug-delivery systems, medical devices, coatings, adhesives, sensors, membranes and consumer goods.
A study led by Oak Ridge National Laboratory subjected tungsten to low energies, akin to normal operations of a fusion reactor (left), and high energies emulating plasma disruptions (right).
A fusion reactor is essentially a magnetic bottle containing the same processes that occur in the sun. Deuterium and tritium fuels fuse to form a vapor of helium ions, neutrons and heat. As this hot, ionized gas—called plasma—burns, that heat is transferred to water t...
Using 3-D printing, ORNL researchers rapidly prototyped a complex gearbox pattern and created sand molds to make no-waste aluminum parts for industry partner, Emrgy Hydro.

Oak Ridge National Laboratory has successfully developed and tested a novel sand casting technique to quickly design complex patterns to fabricate components for industry partner Emrgy Hydro, makers of hydropower devices designed to generate electricity from slow or shallow water flo...

Advanced manufacturing will benefit from additive manufacturing techniques as demonstrated by a team led by Michael Kirka of Oak Ridge National Laboratory.
An ORNL report provides best practices for electric utilities using drones to monitor transmission systems.
Electric utilities seeking to enhance worker safety and system reliability by using drones to inspect their transmission systems can look to a new report by Oak Ridge National Laboratory researchers to help guide their efforts. The report by ORNL’s Unmanned Aerial Systems Research Ce...

It’s not enough to design new drugs. For drugs to be effective, they have to be delivered safely and intact to affected areas of the body. And drug delivery, much like drug design, is an immensely complex task.
3-D visualization of chemically-ordered phases in an iron-platinum (FePt) nanoparticle.

Barely wider than a strand of human DNA, magnetic nanoparticles—such as those made from iron and platinum atoms—are promising materials for next-generation recording and storage devices like hard drives. Building these devices from nanoparticles should increase storage capaci...

Snow falls in winter and melts in spring, but what drives the phase change in between?

Contrasting solvation strategies in conventional electrolytes (top-left) and a new class of Lewis-acidic polymer electrolytes (bottom-left).
Ever since Italian physicist Alessandro Volta invented the first battery out of a stack of copper and zinc disks separated by moistened cardboard, scientists have been searching for better battery materials.
