The electrodeposition of Bi from acidic nitrate solution was examined. Bismuth deposition was determined to be quasi-reversible on Au, with a current efficiency
In a Key Comparison experiment, the Mutual Recognition Arrangement (MRA) requires the calculation of the Degrees of Equivalence (DoE) and the accompanying

In order to improve the NIST low-voltage calibration service for thermal voltage converters, we have constructed an ac Josephson voltage standard system that
We describe a new form of a fluid state equation, based on a conceptual extrapolation from the Debye equation for the specific heat of solid materials. The

The effects of laser fluence on ion formation in MALDI was studied using a tandem TOF mass spectrometer using a Nd-YAG laser and alpha-cyano hydrocinnamic acid
Recent theoretical work has produced quantitatively accurate potential-energy surfaces for water with common gases. These pair potentials have been used to
This article describes how librarians at the Research Library at the National Institute of Standards and Technology planned and conducted focus group interviews
The partitioning of an adaptive grid for distribution over parallel processors is considered in the context of adaptive multilevel methods for solving partial
Abstract--A modified International System of units, SI, based on simply specifying exact numeric values of seven physical constants, is described. This ?set of
Exact analytical solutions are used to investigate the complex eigenfrequencies of tensioned beams with a viscous damper attached transversely near a support
Exact analytical solutions are formulated for the complex eigenmodes of tensioned beams with an intermediate viscous damper. The problem is formulated using the
Cobalt/gold (Co/Au) bimetallic nanoparticles are prepared by synthesizing Au via chemical reduction in the presence of pre-synthesized Co nanoparticles
Alignment for tomography using a transmission electron microscopy frequently uses colloidal gold particles as fiducial reference marks. Typically, there is an
Automated peak identification in electron beam excited x-ray microanalysis with energy dispersive x-ray spectrometry is subject to occasional mistakes even on

A conventional technique for scaling thermal noise power in Johnson Noise Thermometry (JNT) is via resistance ratios. We describe measurements in the low to
Inspired by the development of a collaborative plan on understanding wildland fires, their interaction with weather and the built environment, the National
NIST has developed the capability to measure noise parameters on a wafer int he 1-12.4 GHz range. We describe the measurement method and the uncertainty
