May 26, 2008 Researchers at the University of the Basque Country have used ferromagnetic shape memory alloys to develop experimental devices that can position objects with an incredible accuracy of 20 ...

A magnetic shape-memory alloy composed of nickel, manganese, and gallium responds to magnetic fields and temperature, allowing for the conversion of magnetic-field energy into kinetic energy. Although ...

Shape memory alloys (SMA) remember their original shape and return to it after being heated. Similar to how a liquid transforms into a gas when boiled, SMAs undergo a phase transformation when heated ...

The U.S. National Science Foundation (NSF) has recently reported that two research teams have developed a new porous foam of an alloy that changes shape when exposed to a magnetic field. The NSF ...

Researchers have turned a stubborn alloy into a shape-shifting foam by just giving it a little breathing room. David Dunand, James N. and Margie M. Krebs Professor of Materials Science and Engineering ...

Besides superfluous features like touchscreens and internal cameras, basic refrigerator technology hasn't changed much in decades. They still chill your milk by way of chemical refrigerants and ...

Researchers have made a lighter and potentially cheaper kind of shape-memory alloy: materials that change shape in response to a magnetic field but remember their original shape. The new material, a ...

X-ray studies and fundamental calculations are helping physicists gain molecular level insight into the workings of some magnetic shape-memory materials, which change shape under the influence ...

Researchers from Northwestern University and Boise State University have figured out how to produce a less expensive shape-shifting "memory" foam, which could lead to more widespread applications of ...

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 ...
