Vibrationally-resonant sum frequency generation (VR-SFG) has been used to study the absolute molecular orientational distribution of the pendant phenyl groups...
Among the most important, conservative geochemical tracers are the long-lived isotopes of krypton, 81Kr and 85Kr. Following a very brief review of the metrology...
A Mathematica package BioEqCalc.m has been developed for treating complex equilibria in aqueous solutions. The package is geared towards the treatment of...
The effects of relative humidity ranging from [approximately equal to] 0 % to 90 % on the moisture-enhanced photolysis (MEP) of a partially-methylated melamine...
Many armed star molecules were formed by endlinking monofunctional vinyl sulfone endcapped PEG to the terminal amines dendrimers. Gel permeation chromatography...
The NIST guarded active-arm bridge, using a third dc source and a second detector to balance the guard network, is described. Improvements to the NIST active...
This paper presents a nonlinear dynamics approach for predicting the transition from continuous to shear-localized chip formation in machining. Experiments and...

The use of a cluster (or polyatomic) primary ion projectile for organic SIMS has been demonstrated to increase the yield of characteristic molecular secondary...
Correlated photons can be used to measure of the quantum efficiency of photon counting photodetectors without ties to any externally calibrated standards. We...
Differential scanning calorimeters (DSCs) have been widely used to determine the thermodynamics of phase transitions and conformational changes in biological...
Recent studies suggested that 8,5'-cyclo-2'-deoxyadenosine may play a role in diseases with defective nucleotide-excision repair. This compound is one of the...

An international comparison of 50/60 Hz power is described. The traveling standard was an electronic power transducer which was tested at 120 volts, 5 amperes...
A complete characterizaiton of Zener standards for temperature, pressure, and humidity is being performed to improve the uncertainty of a Measurement Assurance...
