In previous work, we found approximate solutions for paraboloids having perturbations with four-fold axial symmetry in order to model dendritic growth in cubic...
The microstructure and chemistry of (Ba,Sr)TiO 3 thin films deposited on Pt/SiO 2/Si substrates by metalorganic chemical vapor deposition were studied using...
Not only because of its historic and widespread use in applications where its strength and brittle nature are significant factors, but also because it is...

Multilayer media are of increasing importance as magneto-optic and perpendicular media. The properties of successive layers evolve as the layers are epitaxially...
The boundary lubrication characteristics of sulfonates, phenates, and salicylates in a silicon nitride on silicon nitride contact were investigated. The...
Plastic flow surfaces for metal and metal/composite powder compacts with variable cohesive strength are derived using the Beltrami total strain energy criterion...

The effect of the instantaneous application of an electric current during the directional solidification of a binary alloy is considered. The initial state...
Emission experiments, performed at NIST and the Ruhr University, have provided sensitive tests of recent atomic structure calculations. Somewhat surprisingly...
At the ultracold temperatures which occur in cold atom traps and Bose-Einstein condensates only a few partial waves contribute to the scattering of ground-state...
The polarization of light scattered by oxide films thermally grown on photolithographically-generated microrough silicon surfaces was measured as functions of...
We present detailed considerations on the achievable sensitivity in the measurement of birefringence using a high finesse optical cavity, emphasizing techniques...
