A self-erasing chip for security and anti-counterfeit tech
Self-erasing chips developed at the University of Michigan could help stop counterfeit electronics or provide alerts if sensitive shipments are tampered with.
Advanced Optical Materials is an international, interdisciplinary forum for peer-reviewed papers on materials science which focuses on all aspects of light-matter interactions. Advanced Optical Materials was published as a special focus section integrated in Advanced Materials in 2012 and launched as a journal at the start of 2013. Scope of Advanced Optical Materials Advanced Optical Materials is dedicated to breakthrough discoveries and fundamental research in photonics, plasmonics, metamaterials, and more.
