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 ...

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 ...

A new class of materials known as "magnetic shape-memory foams" has been developed. The foam consists of a nickel-manganese-gallium alloy whose structure resembles a piece of Swiss cheese with small ...

The premartensite phase of shape memory and magnetic shape memory alloys is believed to be a precursor state of the martensite phase with preserved austenite phase symmetry. The thermodynamic ...

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 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 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 ...
