An increasing number of technologies demand nanoporous materials with vastly improved physical, mechanical and thermal properties. This manuscript develops the...
Bottom-up superfill during electrodeposition that is used for industrial processing of damascene copper interconnects has also been demonstrated during...
Studies of the infrared spectra of small molecular ions offer valuable information regarding the structures and chemical bonding properties of these species...

Polymer-coated ferromagnetic colloids are first assembled with an applied magnetic field and then permanently fixed into one-dimensional mesostructures using a...
We performed a detailed study of the effect of annealing (at temperatures up to 300°C) on 0.2-3.0 nm thick epitaxial Fe layers deposited on GaAs(001). Using...
Silicon is rather inefficient light emitter due to the indirect-band gap electronic structure, requiring a phonon to balance electron momentum during interband...
A general theory is presented to estimate the uncertainty of a frequency comparison in the presence of dead time or time offset in the measurement. The...

Primary frequency standards with stated inaccuracies of δf/f ~ 10 15 or slightly better are in use today in several national timing laboratories. These...
Counter-flow gradient electrofocusing methods are methods whereby a combination of electrophoresis and a bulk solution counter-flow is used to accumulate or...
NIST has recently established an institutional membership with the Health Industy Business Communication Council (HIBCC) - the ANSI-accredited standards...
Simulation is defined as the imitation of the operation of a system or real-world process over time, and in many cases, manufacturing provides one of the most...
The density variation of the viscosity of xenon gas is determined using molecular dynamics simulation with a semi-empirical pair potential fit to low density...
