Alloys that can return to their original structure after being deformed have a so-called shape memory. This phenomenon and the resulting forces are used in many mechanical actuating systems, for ...

Shape memory materials (SMMs) are featured by the ability to recover their original shape from a significant and seemingly plastic deformation upon a particular stimulus is applied 1. This is known as ...

Laser powder bed fusion, a 3D-printing technique, offers potential in the manufacturing industry, particularly when fabricating nickel-titanium shape memory alloys with complex geometries. Although ...

As air traffic is projected to increase dramatically over the next decade, reducing noise pollution becomes an even more necessary and demanding challenge. Decades of research have been dedicated to ...

Imagine a world of shape-shifters. A surgeon inserts a small lump of plastic into an anesthetized patient and, like magic, it expands into a life-saving mesh tube that keeps a formerly clogged artery ...

The secret to how steel hardens and shape-memory alloys snap into place lies in rapid, atomic-scale shifts that scientists have struggled to observe in materials. Now, Cornell researchers are ...

Researchers have discovered a way to introduce a shape memory effect in bismuth ferrite that is larger than any observed in a metal. This discovery opens the door to applications in a wide range of ...
