Measurements are reported of the electron drift velocity, w, in CHF 3 gas and in its mixtures with argon. The E/N dependence of w in the mixtures exhibits...
We consider the effect of anisotropic kinetics on long-wavelength instabilities during the directional solidification of a binary alloy having a vicinal...

Resonant ultrasonic spectroscopy was used to measure the orthorhombic elastic constants of rolled, polycrystalline plates of Cu, Cu - 5% Zn, and Cu - 15% Zn...
Many liquids cooled to low temperatures form glasses (amorphous solids) instead of crystals. As the glass transition is approached, molecules become localized...
The data reduction techniques necessary for utilizing the capacitance cell described previously by us for thickness measurements (C.R. Snyder and F.I. Mopsik...

We have measured independently both s-wave and p-wave cross-dimensional thermalization rates for ultracold 40K atoms held in a magnetic trap. These measurements...
Vibrationally mediated photodissociation dynamics of water on the first excited electronic state surface (A) has been studied with slit jet-cooled H 2O prepared...

State-to-state rotationally inelastic scattering cross sections of H 2O with Ar are measured under single-collision conditions in crossed supersonic jets at a...
We studied natural organic matter (NOM) rejection and the membran's flux decline during natural water filtration using a charged ultrafiltration membrane based...
Cubic boron nitride (CBN) tool wear in interrupted turning of hardened M50 steel has been investigated. The goal was to identify dominant wear mechanism during...

This paper describes methods for the extraction of sheet resistance from V/I measurements made on four-terminal sheet resistors incorporated into electrical...
The National Institute of Standards and Technology (NIST) hosted the 1998 Conference on Precision Electromagnetic Measurements (CPEM'98) in the Washington...
The calculable capacitor at National Institute of Standards and Technology (NIST) links the U.S. capacitance unit to the SI unit and has a relative standard...

A capillary electrophoretic (CE) assay for oxalate has been applied to the quantitative determination of free oxalate in amniotic fluid. Indirect absorbance...
Ultrathin films with perpendicular magnetization convert from a single domain state into a multidomain structure as the reorientation phase transition to an in...
