21. Surface-Enhanced Raman Spectroscopy via Gold Nanostars
Published: 9/28/2008
Authors: Emren Nalbant-Esenturk, Angela R Hight Walker
Abstract: Anisotropic metallic nanoparticles have unique optical properties, which lend them to applications such as Surface Enhanced Raman Spectroscopy (SERS). Branched and star-shaped gold nanoparticles have been prepared in aqueous phase by seed-mediated gr ...

22. Origin of the exceptional negative thermal expansion in metal-organic framework-5 Zn^d4^O(1,4-benzenedicarboxylate)^d3
Published: 8/1/2008
Authors: Wei Zhou, Hui Wu, Taner Yildirim, Jeffrey Ray Simpson, Angela R Hight Walker
Abstract: Metal-organic framework-5 (MOF-5) was recently suggested to possess an exceptionally large negative thermal expansion coefficient. Our direct experimental measurement of the thermal expansion of MOF-5, using neutron powder diffraction, in the tempe ...

23. Influence of the Colloidal Environment on the Magnetic Behavior of Cobalt Nanoparticles
Published: 11/6/2007
Authors: Guangjun Cheng, Cindi L Dennis, Robert D Shull, Angela R Hight Walker
Abstract: The magnetic properties of 10 nm cobalt (Co) nanoparticles in 1,2-dicholorbenenze (DCB) are investigated via a series of magnetization (M) vs. temperature (T) measurements. A rapid rise in magnetization around 250 K during warming and a sudden drop a ...

25. Synthesis and Characterization of Cobalt/Gold Bimetallic Nanoparticles
Published: 4/1/2007
Authors: Guangjun Cheng, Angela R Hight Walker
Abstract: Cobalt/gold (Co/Au) bimetallic nanoparticles are prepared by synthesizing Au via chemical reduction in the presence of pre-synthesized Co nanoparticles. Transmission electron microscopy (TEM), ultraviolet-visible (UV-vis) absorption spectrometry, and ...

28. Comparative Measures of Single Wall Carbon Nanotube Dispersion
Published: 9/14/2006
Authors: Jeffrey A Fagan, Brian Landi, Idan Mandelbaum, Vardhan Bajpai, Barry J. Bauer, Kalman D Migler, Jeffrey Ray Simpson, Angela R Hight Walker, Ryan Raffaelle, Erik K. Hobbie
Abstract: Model polymer composites of DNA wrapped single-wall carbon nanotubes (SWNTs) dispersed in polyacrylic acid are used for a systematic comparison of the different metrologies currently used to evaluate SWNT dispersion. Application of a pH-controlled v ...

29. Method for Measuring the Raman Gain Tensor in Optical Fiber
Published: 4/7/2006
Authors: Idan Mandelbaum, M Bolshtyansky, T F Heinz, Angela R Hight Walker
Abstract: In this paper we introduce a technique to measure the tensor properties of the Raman gain in a short piece (10m) of silica based polarization maintaining optical fiber. We present the results of the measurement and show agreement with new and previo ...
