By Ariel DuChene, Syracuse University A team led by Patrick T. Mather, director of Syracuse Biomaterials Institute (SBI) and Milton and Ann Stevenson professor of biomedical and chemical engineering in Syracuse University's L.C. Smith College of Engineering and Computer Science (LCS), has succeeded in applying the concept of functionally graded materials (FGMs) to shape memory polymers (SMPs). SMPs are a class of "smart" materials that can switch between two shapes, from a fixed (temporary)...

"Smart" alloy stretches, contracts by almost 10 percent By chance, two friends, out of the 3,000 scientists attending the fall 2006 Materials Research Society meeting in Boston, ran into each other outside the Hynes Convention Center. Peter Mllner and David Dunand had both graduated from the Swiss Federal Institute of Technology (ETH) Zurich. Mllner, now at Boise State University, was researching magnetic alloys that can change their shape in the presence of a magnetic field. Meanwhile,...

Metallic foam less expensive to make, leading to more applications 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 the material, such as in surgical positioning tools and valve mechanisms. David Dunand, the James N. and Margie M. Krebs Professor of Materials Science and Engineering at Northwestern, has been collaborating with Peter Mllner,...

ATLANTA, Sept. 23 /PRNewswire/ -- MedShape Solutions, Inc. announced today the first FDA cleared shape memory PEEK (polyaryletheretherketone) device for orthopedics using proprietary shape memory PEEK Altera(TM) material. The Morphix(TM) Suture Anchor was recently granted FDA clearance and will be released to select U.S. markets in the coming months. Over $2.5B of PEEK-based implants are sold every year in the field of orthopedics. These devices range from spinal cages to suture anchors...

Shape memory alloys can "remember" a condition. If they are deformed, a temperature change can be enough to bring them back to their original shape. A simulation calculates the characteristics of these materials. It seems like a magic trick. A man takes a paper clip and bends it in such a way that it merely resembles a crooked piece of wire. Then, he throws the clip into a bowl of hot water. Within a fraction of a second, the metal wire returns to the shape of a paper clip. This...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
