Standardization of Isotope Ratio Measurements for Doping Control

December 1, 2004
Author(s)
R M. Verkouteren
Pharmaceutical steroids are known to differ in isotopic composition from those produced naturally in the body. By measuring the 13 C/ 12C ratio of specific steroids deteched in urine, the technique of Gas Chromatography-Combustion-Isotope Ratio Mass

Fermi Level Alignment and Electronic Levels in Molecular Wire Self-Assembled Monolayers on Au

October 1, 2004
Author(s)
Christopher D. Zangmeister, Steven W. Robey, Roger D. van Zee, Yuxing Yao, J M. Tour
A combination of one- and two-photon photoelectron spectroscopies are used to determine the electronic structure around the Fermi level for self-assembled monolayers of a prototypical molecular wire , 4,4 -(ethynylphenyl)-1-benzenethiol (C6H5-C≡C-C6H4-C≡C-

Template Fabrication of Protein-Functionalized Gold-Polypyrrole-Gold Segmented Nanowires

September 1, 2004
Author(s)
R M. Hernandez, Lee J. Richter, Stephen Semancik, Stephan J. Stranick, Thomas E. Mallouk
Gold nanowires containing protein-modified poly(pyrrole) (Ppy) junctions were synthesized electrochemically using porous aluminum oxide as a template. The effects of the conditions of electrochemical synthesis on Ppy growth and protein (avidin or
