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

Passive and Active Characterization of Hybrid Glass Substrates for Telecommunication Applications

January 1, 2002
Author(s)
Joseph S. Hayden, Robert D. Simpson, Samuel D. Conzone, Robert K. Hickernell, Berton Callicoatt, Alexana Roshko, Norman Sanford
Phosphate glasses have become increasingly popular for planar waveguide devices owing in part to the development of a number of different commercial compositions with a wide range of optical, physical, chemical and laser properties. In addition, the recent

Personal Authentication Through Biometric Technologies

January 1, 2002
Author(s)
Fernando L. Podio
¿¿¿Biometric authentication technologies such as face, finger, hand, iris, and speaker recognition are commercially available today and are already in use. Recent advances in reliability and performance and recent cost drops make these technologies

Phase Control of Li 2 Wave Packets on Two Electronic Curves

January 1, 2002
Author(s)
H U. Stauffer, J B. Ballard, Z Amitay, S R. Leone
Coherent dynamics of rotational wave packets in two Li 2 electronic states are manipulated using phase-tailored femtosecond pulses. A shaped preparation pulse simultaneously creates wave packets in the A{ 1ς u +) electronic states, subsequently ionized

Phase Diagram of a Nearly Isorefractive Polyolefin Blend

January 1, 2002
Author(s)
Haonan Wang, Charles C. Han, K Shimizu, Erik K. Hobbie, Z G. Wang, J C. Meredith, Alamgir Karim, Eric J. Amis, B S. Hsiao, E T. Hsieh
The phase diagram of coexisting liquid-liquid phase separation (LLPS) and crystallization in nearly isorefractive blends of statistical ethylene/hexane and ethylene/butene copolymers has been investigated. A variety of techniques that exploit

Phase Relationships and Phase Formation in the System BaF 2 -BaO-Y 2 O 3 -CuO x -H 2 O

January 1, 2002
Author(s)
Winnie K. Wong-Ng, Lawrence P. Cook, J Suh, Igor Levin, Mark D. Vaudin, Ron Feenstra, James P. Cline
The interplay of melting equilibria and reaction kinetics is important during formation of the Ba2YCu3O6+x (Y-213) phase from starting materials in the quaternary reciprocal system Ba,Y,Cu//O,F. For experimental investigation of the process we are using a

Phase Separation in Ultrathin Polymer Films

January 1, 2002
Author(s)
Alamgir Karim, Jack F. Douglas, Li Piin Sung, B D. Ermi
Changes in phase separation morphology occurring in thin polymer blend films is discussed. These changes are especially large when the films are thinner than the scale of the bulk material interfacial profile width. Under these circumstances, phase
