In the last several years we have made many improvements to NIST-F1 (a laser-cooled Cs fountain primary frequency standard) resulting in over a factor of 2...
A study is made of radial crack evolution in curved brittle layers on compliant support substrates. Three-dimensional boundary element analysis (BEA) is used to...

As part of an ongoing effort to better understand the performance of indoor air cleaners in real buildings, the National Institute of Standards and Technology...
A third generation silicon drift detector (SDD), a silicon multicathode detector (SMCD), was tested as an analytical x-ray spectrometer on a scanning electron...
The goal of this study was to determine the effect of varying the chemistry of the interfacial phase on critical composite properties in dental nanocomposite...
The structure of mesoporous materials, in terms of morphology and orientation, is critical for numerous applications. X-ray reflectivity (XR) and small angle...

We outline a method to fabricate gradient combinatorial libraries that explore architectural parameters in surface-grafted block copolymers (BCs). In addition...
Approximately a million bone grafts are performed each year in the United States, and this number is expected to increase rapidly as the population ages...
