Implanted atoms create unique electrical IDs that distinguish bona fide devices from forgeries

If someone sells you a luxury handbag from Paris, France, but it turns out be a forgery from Paris, Texas, the counterfeit item might cost you a thousand bucks and the crook could wind up in jail. But if a counterfeit electronic ...

New method greatly improves X-ray nanotomography resolution

It's been a truth for a long time: if you want to study the movement and behavior of single atoms, electron microscopy can give you what X-rays can't. X-rays are good at penetrating into samples—they allow you to see what ...
