Crystals of the enzyme RNase S were grown at micro and unit gravity using a dialysis-based dynamically controlled device. Crystals were grown at 24 C on space...
Microcalorimetry, spectrophotometry, and high-performance liquid chromatography (h.p.l.c.) have been used to conduct a thermodynamic investigation of the...
A 35-kilowatt roof top photovoltaic system has been installed at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland. The system...
Proper curing of cement-based materials will help to develop a discontinuous pore structure that will aid in extending a structure's service life by reducing...

Collaborative development of engineered products in a business-to-business (B2B) environment will require more than just the selection of components from an on...
We discuss atomic force acoustic microscopy (AFAM) methods to determine quantitative values for the elasticproperties of thin films. The AFAM approach measures...

In-situ high-temperature x-ray diffraction (HTXRD) was used to study the phase formation and reaction kinetics of the Ba 2Ycu 3O 6+x (Y-213) phase using the ex...
In previous papers, we have introduced a percolation model for the transport of strain through a deforming metal. In this paper, we summarize the results from...

Electron energy loss spectroscopy in a transmission electron microscope (TEM) was used to measure elemental profiles of Si, 0 and N in the SiO x/Si xN y/SiO x...
A defected zone in the HVPE (hydride vapor phase epitaxy)-deposited GaN located near an interface with a SiC substrate was investigated by transmission electron...
This study seeks to elucidate structure-property relationships in a series of unfilled dental copolymers and their composites. The copolymers/composites were...
The gloss value of a test sample is determined relative to a standard, generally a polished piece of black glass. Therefore, gloss is a dimensionless quantity...
We demonstrate how a topological atom laser can be realized by output coupling a trapped vortex state with a Raman scattering process. We find a linearized...
Hexafluoro-1,3 butadiene (C,F,) is a potential new etching gas for the manufacturing ol semiconductors which has a very low global warming potential, unlike...
Experimental studies of the energetics and vibrational spectrum of the chloroperoxyl radical, ClOO, are contradictory. The most recent experiment accessed the...
The crystallization behavior of thin polypropylene films with and without 4-biphenyl carboxylic acid as a nucleating agent was investigated using high...
This article reviews the primary concepts of repository-centered development with the Unified Modeling Language, explaining the relation between notation...
This article compares Activity models of the Unified Modeling Language, version 2 (UML 2) [U2 Partners 2003], to a popular systems engineering (SE) flow diagram...
