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 ...

After being severely and quasi-plastically distorted, shape memory materials (SMMs) are able to recover their original shape when a right stimulus is applied 1. This phenomenon is known as the shape ...

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 ...

The technique of keyhole surgery minimises scarring, speeds healing and reduces the risk of infection. However, it is extremely difficult to carry out delicate surgical procedures accurately in a ...

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 ...

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 ...
