Dynamic nanoindentation was preformed on a cured epoxy, poly(methyl methacrylate), and poly(dimethyl siloxane) or PDMS. These samples, two glassy polymers and a...
Knowledge is central to a mobile robot's ability to carry out its missions and adapt to changes in the environment it is traversing. The knowledge subsystem...
The vapor pressures of n-heptane have been measured using comparative ebulliometry with water as the reference substance. The measurements cover the temperature...

We have developed a ¿global¿ crossover (GC) statistical associating fluid theory (SAFT) equation of state (EOS) for associating fluids, which incorporates non...
X-ray diffraction topography, which is sensitive to local strain and/or crystallographic orientation, provides a unique view of the surface of single-crystal...
A phase stabilized femtosecond laser comb is directly used for high resolution spectroscopy and absolute optical frequency measurements of one and two photon...
The surfaces of strained mild steel sheet specimens were examined with scanning laser confocal microscopy. Rigorous assessments were employed to establish the...
The Symposium on Metrology and Standards for Cell Signaling: Impact on Tissue Engineering, was held at the National Institute for Standards and Technology (NIST...
