(Phys.org) —Listen up nickel-titanium and all you other shape-memory alloys, there's a new kid on the block that just claimed the championship for elasticity and is primed to take over the shape memory apps market at the nanoscale. A research team at Berkeley Lab has discovered a way to introduce a recoverable strain into bismuth ferrite of up to 14-percent on the nanoscale, larger than any shape-memory effect observed in a metal. This discovery opens the door to applications in a wide range of fields, including medical, energy and electronics.
