61. Investigation of the Relationship Between Microstructure and Appearance Properties of Coating Materials
Published: 10/1/2000
Authors: Li Piin Sung, Maria E Nadal, M E. McKnight, J V Nguyen, C -J Lin
Abstract: A series of experiments was carried out to investigate the relationship between the microstructure and the appearance of coated materials using confocal laser microscopy and optical scattering metrology. Microstructural properties such as surfaces r ...

62. Characterization of Coating Microstructure Using Laser Scanning Confocal Microscopy
Published: 8/1/2000
Authors: Li Piin Sung, Maria E Nadal, Paul E Stutzman, M E. McKnight
Abstract: The appearance of coating materials depends on the physical attributes of the object's interaction with light. These physical attributes include the light source, the angle of illumination, the viewing angle, and the optical reflectance properties o ...

63. Neutron Reflectivity Study of Diblock Formation During Reactive Blending Processes
Published: 8/1/2000
Authors: Makoto Hayashi, H Grull, A R Esker, M J Weber, Li Piin Sung, Sushil K. Satija, Charles C. Dr. Han, TT Hashimoto
Abstract: In a series of neutron reflectivity experiments, we studied the fundamental process of diblock formation during reactive blending processes of an immiscible blend comprised of normal polysulfone (hPSU) containing 30 % reactive endgroup-modified deute ...

64. Characterizing the Appearance and Its Related Microstructure of Metallic-Flaked Coatings
Published: 6/1/2000
Authors: Li Piin Sung, Maria E Nadal, M E. McKnight
Abstract: The National Institute of Standards and Technology (NIST) is conducting a study to advance the science of measuring and modeling the optical scattering properties of materials. Results of measurements and mathematical models for quantifying light sc ...

65. Adsorption of Dodecahydroxylated-Fullerene Monolayers at the Air Water Interface
Published: 1/1/2000
Authors: Li Piin Sung, W J Liua, U Jeng, T L Lin, S H Laib, M C Shih, C S Tsao, L Y Wang
Abstract: We study the adsorption behaviors of dodecahydroxylated-fullerene C60(OH)12 at the air-water interface. With the hydrophilicity imposed by the 12 hydroxy groups randomly bounded on the C60 cage, C60(OH)12 can dissolve in water slightly. Surface press ...

66. Polarized Light Scattering Measurements of Dielectric Spheres upon a Silicon Surface
Published: 7/1/1999
Authors: Li Piin Sung, George William Mulholland, Thomas Avery Germer
Abstract: The polarization of light scattered into directions out of the plane of incidence by polystyrene latex spheres upon a silicon substrate was measured for p-polarized incident light. The experimental data show good agreement with theoretical prediction ...

67. Polarized Light Scattering Measurements of Roughness, Subsurface Defects, Particles, and Dielectric Layers on Silcon Wafers
Published: 7/1/1999
Authors: Thomas Avery Germer, Li Piin Sung
Abstract: This article outlines theoretical and experimental results for polarized light scattering from five different sample configurations: surface roughness of a single interface, defects below a single interface, spherical particles above a single surface ...

68. Polarization of Light Scattered by Particles on Silicon Wafers
Published: 1/1/1999
Authors: Li Piin Sung, George William Mulholland, Thomas Avery Germer
Abstract: Bidirectional ellipsometry has been developed as a technique for distinguishing among various scattering features near surfaces.Employi Employing incident light with fixed polarization, the technique measures the principal angle of polarization and t ...

69. Evaluation of Microstructure of BaTiO^d3^-Polymer Composites by Confocal Microscopy
Published: Date unknown
Authors: C. K. Chiang, Li Piin Sung, R Popielarz, Jan Obrzut
Abstract: Laser scanning confocal microscopy has been applied to examine the distribution of BaTiO3 particles in ceramic-polymer composite films. The thin-slice images of the thickness of the order of one micron allowed us to visualize the micron-size particl ...

70. The Relationship Between the Microstructure and Durability of Fluorinated Acrylic Coatings
Published: Date unknown
Authors: Li Piin Sung, D L Ho
Abstract: This paper presents research results on the relationships between microstructure and the performance/weatherability of fluoropolymer/acrylic coatings. We studied fluoropolymer/acrylic blends of identical composition, prepared as films using three dif ...
