Scientists expected to see slow, random movement when they dropped lead atoms on a lead-on-silicon surface. But they saw instead? Fast, organized atoms. The unusual “explosive” movement may represent a new way to grow perfect, tiny metal nanostructures for nanostransistors and nanomagnets.
The Critical Materials Institute, a U.S. Department of Energy Innovation Hub led by the Ames Laboratory, has created a new chemical process that makes use of the widely available rare-earth metal cerium to improve the manufacture of nylon.
Scientists at the Critical Materials Institute have developed a two-step recovery process that makes recycling rare-earth metals easier and more cost-effective.
