Rheo-Optic Studies of Carbon Nanotube Suspensions

January 1, 2006
Author(s)
D J. Fry, B Langhorst, Haonan Wang, Barry J. Bauer, Erik K. Hobbie
We have used a polarization modulation technique to investigate optical anisotropy of multi-walled and single-walled carbon nanotubes suspended in a variety of solvents. Measurement of birefringence and dichroism have been performed as a function of shear

SI Realization of Small Forces Using an Electrostatic Force Balance

January 1, 2006
Author(s)
Jon R. Pratt, John A. Kramar
We describe the realization of micronewton forces in a fashion consistent with the International System of Units (SI) using the National Institute of Standards and Technology (NIST) electrostatic force balance. A comparison between deadweight and

Small Angle Neutron Scattering from Labeled Single Wall Carbon Nanotubes

January 1, 2006
Author(s)
Barry J. Bauer, Erik K. Hobbie, Matthew Becker
Small angle neutron scattering (SANS) is used with the high concentration method to extract single particle scattering from single wall carbon nanotubes (SWNTs). The SWNT material was labeled by covalently attaching -C4H9 or -C4D9 groups by use of free
