Researchers Perfect New Technique for Making "Memory Crystals"

Scientists from Japan have found an easier way to make a special kind of crystal that can "remember" its shape if deformed. These materials--known as shape memory alloys--are valuable in a range of applications from medical devices to building construction, but manufacturing them can be difficult and costly. A recent paper published in Nature Communications is looking to change that.Growing the size of crystalsYou can bend and twist a rod made of shape memory alloy (within reason), and then rest...
