MedShape Inc., Atlanta, reports that during its targeted soft launch period, DynaNail has been successfully implanted in over 100 tibiotalocalcaneal (TTC) fusion procedures. Because the internal nickel titanium (Nitinol) element maintains the target fusion bones in close apposition and under sustained compression, fusions are being observed with the DynaNail TTC Fusion System in high-risk patients, specifically those who require bone allografts.
A research team at Lawrence Berkeley National Laboratory, Calif., has discovered a way to introduce a recoverable strain into bismuth ferrite of up to 14% on the nanoscale, larger than any shape-memory effect observed in a metal. Bismuth ferrite is a multiferroic compound comprised of bismuth, iron, and oxygen. It displays both ferroelectric and ferromagnetic properties, meaning it will respond to the application of external electric or magnetic fields.

How XRF Analysis Works This video shows how handheld X-ray fluorescence analyzers work.
Metlab, Philadelphia, recently heat-treated custom fabricated leaf springs of an antique 1932 Alfa Romeo sports car. The springs were made for a Pennsylvania-based automobile restorer. The leaf springs, made from HR-5160 steel, were patterned after the original springs, which were too worn to be reused. The replacement springs were hardened and press quenched into the shape of the spring, and were tempered to a final hardness of HRC 28–32, duplicating the hardness as measured on the originals.
