Samples and Standards

December 13, 2004
Author(s)
Richard M. Lindstrom, C Yonezawa
For analytical accuracy, the detailed interaction of neutrons with the sample is of more importance in prompt-gamma activation analysis (PGAA) with a neutron beam than in conventional activation analysis. Selection of an optimum sample size and shape is

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

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-

Structure of Polystyrene at the Interface With Various Liquids

September 4, 2004

Clayton S. Yang, P T. Wilson, Lee J. Richter
Vibrationally resonant sum frequency generation (VR-SFG) is used to determine the structure of the phenyl side groups of deuterated polystyrene at the liquid/solid interface for the nonsolvent liquids: hexane, methanol, ethanol, glycerol, and water. The
