Optical Reflectance of Metallic Coatings: Effect of Aluminum Flake Orientation

January 1, 2002
Author(s)
B Laurenti, Egon Marx, Maria Nadal, M E. McKnight, L Sung
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

Organization of Hybrid Dendrimer-Inorganic Nanoparticles on Amphiphilic Surfaces

January 1, 2002
Author(s)
Franziska Grohn, X H. Gu, H Grull, J C. Meredith, G Nisato, Barry J. Bauer, Alamgir Karim, Eric J. Amis
Nanosize dendrimer-inorganic hybrid particles have been selectively deposited on micron- scale hydrophilic domains of amphiphilic surfaces, both on SAMs of alternating stripes of acid- and methyl- terminated thiols and on the amphiphilic phase of a PDLA

Overview of the Radiometric Calibration of MOBY

January 1, 2002
Author(s)
D K. Clark, M Feinholz, M Yarbrough, B. Carol Johnson, Steven W. Brown, Y S. Kim, R Barnes
The Marine Optical Buoy (MOBY) provides values of water-leaving radiance for the calibration and validation of satellite ocean color instruments. Located in clear, deep ocean waters near the Hawaiian Island of Lanai, MOBY measures the upwelling radiance
