Chemists at the University of California are developing a future display technology using nanoscale-sized iron oxide rods that shine when exposed to an external magnetic field. Though in its early stages, the research could pave the way for producing magnetically responsive, ultra high-res displays with significantly reduced dimensions and power demands.
