W K. Hensinger, H Haeffner, A Browaeys, N R. Heckenberg, Kristian Helmerson, C R. McKenzie, William D. Phillips, S L. Rolston, H Rubinsztein-Dunlop, B Upcroft

Effect of Aluminum Flake Orientation on Coating Appearance

January 1, 2001
Author(s)
L Sung, Maria Nadal, M E. McKnight, Egon Marx, R Dutruc, B Laurenti
The orientation of platelet-like pigments in coatings is affected by the processing conditions resulting in appearance variations of the final product. A set of aluminum-flake pigmented coatings having different flake orientations was pre-pared using

Effects of Cleaning on the US Prototype Kilograms

January 1, 2001
Author(s)
Zeina J. Kubarych, R S. Davis
This paper dicusses the stability of national prototype kilograms No. 4 and No. 20, belonging to the United States. Calibration history, changes in mass with respect to time, and effects on mass and surface profiles due to cleaning and washing are

Elastic Moduli of Model Random Three-Dimensional Closed-Cell Cellular Solids

January 1, 2001
Author(s)
A P. Roberts, Edward Garboczi
Most cellular solids are random materials, while practically all theoretical results are for periodic models. To be able to generate theoretical results for random models, the finite element method (FEM) was used to study the elastic properties of solids

Electron Attachment Cross Sections and Negative Ion States of SF6

January 1, 2001
Author(s)
Loucas G. Christophorou, James K. Olthoff
A comprehensive and critical assessment of published data on the total, dissociative, and nondissociative electron attachment cross sections for SF 6 allowed us to recommend or suggest room temperature values for these cross sections over an energy range

Electron Interactions with c-C 4 F 8

January 1, 2001
Author(s)
Loucas G. Christophorou, James K. Olthoff
The limited electron collision cross-section and transport-coefficient data for the plasma processing gas perfluorocyclobutane (c-C 4F 8) are synthesized, assessed, and discussed. These include cross sections for total electron scattering, differential
