Can nanotechnology save the day for hybrid and electric cars? Electric motor technology has long relied on powerful rare-earth magnets, which are made from elements that naturally occur in short and scattered supply. Not only are these elements uncommon, but also they reside in a part of the periodic table of elements that affords them somewhat mysterious properties. The rare earths are everywhere in the technologies we depend on: brilliant phosphors, hard drives, clean cars.
China, who produces over 95% of the world’s supply of rare-earths, threatens to reduce their export. Scientists need to look for alternatives. Nanotechnology just might be the answer. Conventional magnets can be made stronger by blending nanoparticles of iron and cobalt with a small amount of rare earth elements, resulting in more magnetic bang for the buck. Dr. Karen Frindell, Dean of Science, Technology, Engineering, and Mathematics at SRJC, will give a tour of the periodic table that will tell why rare earth elements are so special and useful and show how nanotechnology might be the creative solution to our desire for more of something that might be running out.
