We perform simulations of filled and nanofilled polymers using a combination of molecular and mesoscale simulation techniques. Molecular dynamics simulations
Low expansion materials used in electronic devices require a tool that has a commensurate resolution for measuring deformation, such as the atomic force or
Wavelength calibration of equipment in the 1500 nm region is essential to ensure channel stability and characterize optical components for wavelength division
We examine these isotopic dependence for the case of the e-H2 triple point (TP), and the two vapor pressure (VP) points of the ITS-90 defined near 33 kPa and
The NIST Industrial Thermometer Calibration (ITC) Laboratory provides calibrations of industrial thermometers over the range from 196 C to 550 C. The different

A suitable femtosecond (fs) laser system can provide a broad band comb of stable optical frequencies and thus can serve as an rf/opticalcoherent link. In this
X-ray methods can provide measurements that, for certain parameters of great technological importance, are the most accurate and sensitive available. Their
State-selective coherent phase control using single shaped femtosecond laser pulses is implemented to achieve forward and backward shifts in time (up to a
