Scientists develop rare earth free magnet for use in industrial motors

Scientists are working to find alternatives to rare-earth-based magnets that can function well in motors, because rare earth materials are expensive and can experience supply chain issues. One solution to this challenge was discovered by a team of researchers and industry partners led by scientists at the U.S. Department of Energy Ames National Laboratory. They developed a rare-earth-free bonded magnet that not only retains its magnetism at high temperatures, coercivity nearly doubles with a 100°C (212°F) increase from room temperature.

Ames National Laboratory to test new electrical transmission line that could improve grid resiliency

Material scientists from the U.S. Department of Energy’s Ames National Laboratory are moving into the field-testing stage of a new type of high voltage overhead power conductor (cable).

New process tackles pollution on two fronts: plastic waste and fuel emissions

What if we could help the global plastic waste problem and the transportation industry with the same technology? A team of scientists from the U.S. Department of Energy’s Ames National Laboratory are doing just that. The team, led by Aaron Sadow and Wenyu Huang, recently developed a chemical conversion process that makes diesel out of plastic waste.

Scientists are shaking up lithium extraction with a different kind of chemistry

Scientists at the Critical Materials Innovation (CMI) Hub, led are using mechanochemistry to shake up the conventional understanding of chemical reactions, using mechanical forces that agitate, tumble, and smash solids to initiate chemical reactions. Their new process, MELLT, is a creative solution to increase and diversify the supply of lithium in the United States.

New AC tech for military vehicles could revolutionize cooling and heating for all

The U.S. Department of Defense (DOD) is funding a project led by Ames National Laboratory scientists to develop a new type of air conditioning system based on elastocaloric cooling technology that requires no harmful refrigerants.
