Effect of Ordering on Spinodal Decomposition of Liquid-Crystal/Polymer Mixtures

January 1, 1999
Author(s)
A M. Lapena, S C. Glotzer, Stephen A. Langer, A J. Liu
Partially phase-separated liquid-crystal/polymer dispersions display highly fibrillar domain morphologies that are dramatically different from the typical structure found in isotropic mixtures. To explain this, we explore the coupling between phase

Effects of Environmental Aging on the Properties of Pultruded GFRP

January 1, 1999
Author(s)
Kate Liao, Carl R. Schultesiz, Donald L. Hunston
Pultruded glass-fiber-reinforced vinyl ester matrix composite coupons were subjected to environmental aging in order to study their durability since such composites are of interest for infrastructure applications. Specimens were tested as received and

Enhancement of R123 Pool Boiling by the Addition of N-Hexane

January 1, 1999
Author(s)
Mark A. Kedzierski
This paper presents the heat transfer data used to file international patent WO 94/18282. The data consisted of pool boiling performance of a GEWA-TTM surface for three fluids: (1) pure R123, (2) R123/n-hexane (99/1), and (3) R123/n-hexane (98/2). The heat

Evaluation of Kitchen Cooking Appliance Efficiency Test Procedures

January 1, 1999
Author(s)
Steven J. Nabinger
In 1978, the Department of Energy (DOE) published a Final Rule containing test procedures for measuring the efficiency and energy consumption of conventional ranges, ovens, cooking tops, and microwave ovens. Based on a number of technical concerns

Evaluation of the NASA Langley Research Center Mode-Stirred Chamber Facility

January 1, 1999
Author(s)
John M. Ladbury, Galen H. Koepke, Dennis G. Camell
We performed extensive tests on three mode-stirred (reverberation) chambers operated by the High Intensity Radiation Laboratory located at the National Aeronautics and Space Administration Langley Research (NASA/LaRC) in Hampton, VA.

Evaluation of Variance in Zeta Potential Measurements

January 1, 1999
Author(s)
M Chapman-Wilbert, S Delagah, J J. Pellegrino
We evaluated sources of varience in the measurement of the surface zeta potential of flat sheet specimens of cellulose di/triacetate membranes with a commercial electrokinetic analyzer. Two measurement methods were evaluated: the instrument's standard
