... TECHNICAL MERIT RELATIVE TO STATE OF THE ART The technical merit of the work in the Materials Reliability Division is high, whether in the historic role of supplying Charpy test specimens or at the new frontier of exploring the application of stress measurements to biological systems. The ability to address a diversity of projects attests to the quality of the staff and the management of the division.

... ACHIEVEMENT OF OBJECTIVES AND IMPACT The technical work of the division is grouped in three topical areas: structural materials, cell and tissue mechanics, and nanoscale reliability, as discussed below. Structural Materials Group The Structural Materials Group has core competencies in mechanical testing on a macroscale and in developing standard measurement techniques for materials and properties that are critical to the nation's infrastructure.

... In the rapidly developing field of tissue and cell engineering, NIST has a vital role in indentifying the crucial parameters that will need to be measured. The Bioreactors project has established a strong and promising collaboration with a University of Colorado research group for investigating the effect of different types of forces on the histology, growth morphologies, and various tissue expressions under realistic in vitro tissue growth environments.

... to 45 nm today and 20 nm in the next few years, perfectly induced localized strains in device structures can enhance electron and hole mobility by more than 30 percent, leading to faster devices. Strain metrology, therefore, is indispensable for the U.S.

... One approach, taken both at NIST and at the Max Planck Institute in Germany (by a NIST researcher working there) , is to use cyclic Joule heating to differentially strain and hence fatigue the interconnect lines while monitoring their microstructural changes with complementary electrical measurements.
