Axon-mimicking materials show promise for more efficient computing
2024-09-12 21:59:15
A team of researchers from Texas A&M University, Sandia National Lab—Livermore, and Stanford University are taking lessons from the brain to design materials for more efficient computing. The new class of materials discovered is the first of their kind—mimicking the behavior of an axon by spontaneously propagating an electrical signal as it travels along a transmission line. These findings could be critical to the future of computing and artificial intelligence.
New computer simulations help scientists advance energy-efficient microelectronics
2024-09-12 21:59:15

Recovering rare earth elements from coal ash for clean energy technologies
2024-09-12 20:18:46
As the world transitions away from fossil fuels, the demand for rare earth elements (REEs) is only going to increase. These elements are vital to the production of technologies that will make the transition to green energy possible. While REEs are not technically rare, large deposits are found in only a few locations around the world—mostly in China—and they are difficult to extract.
