Researchers use quantum physics for counterfeit detection
Scientists from Lancaster University have developed a foolproof anti-counterfeiting measure using a combination of quantum physics and smartphone technology. Previously, the team created unique atomic-scale IDs based on irregularities found in 2D materials such a graphene -- irregularities which, unlike current anti-counterfeiting technology such as holograms, are impossible to clone. Quantum physics amplifies these irregularities and, once turned into a tag, makes it possible to "fingerprint" objects.
Microscope can scan chemical processes in real-time
Atomic force microscopes are the tool of choice to see the tiniest atomic structures, right down to hydrogen bonds. The drawback with current models is that they're too slow to create anything but static images, making them useless for processes like chemical reactions. However, MIT researchers have created a prototype model that's 2,000 times faster than any commercial product, making it feasible for video (below). "People can see, for example, condensation, nucleation, dissolution or deposition of material in real-time -- things [they've] never seen before," says MIT professor Kamal Youcef-Toumi.
