Space

+ - Foams with good memory for space applications

Roland Piquepaille writes "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 states that this new material is able to remember its original shape after it's been deformed by a physical or magnetic force. This polycrystalline nickel-manganese-gallium alloy is potentially cheaper and lighter than other materials currently used in devices ranging from sonar to precision valves. It also could be used to design biomedical pumps without moving parts and even for space applications and automobiles. But read more for additional references and a photograph showing an example of such a magnetic shape-memory foam."

Due to lack of disk space, this fortune database has been discontinued.
