Rolf L. Zeisler, Rabia Oflaz, Ralph E. Sturgeon, Rick L. Paul, Brian E. Lang, Jeffrey A. Fagan, Joseph W. Lam, Anthony Windust, P Grinberg, Benoit Simard, Christopher T. Kingston
Several techniques were evaluated for the establishment of reliable water/moisture content of single-wall carbon nanotubes. Karl Fischer titration (KF) provides for a direct measure of the water content and was used for benchmarking against results

Elemental Analysis of a Single-Walled Carbon Nanotube Candidate Reference Material

October 15, 2010
Author(s)
Rolf L. Zeisler, Rick L. Paul, Rabia Oflaz, Lee L. Yu, Jacqueline L. Mann, William R. Kelly, Brian E. Lang, Stefan D. Leigh, Jeffrey A. Fagan
A material containing single-walled carbon nanotubes (SWCNTs) together with other carbon species, cata-lyst residues, and trace element contaminants has been prepared by the National Institute of Standards and Technology for characterization and

Hybridization Thermodynamics of Bound DNA

Brian E. Lang
Isothermal Titration Calorimetry was used to study the thermodynamics of hybridization on DNA-functionalized colloidal gold nanoparticles. When compared to the thermodynamics of hybridization of DNA that is free in solution, the differences in the values

Thermodynamics of the Hydrolysis Reactions of +--D-galactose 1-phosphate, sn-glycerol 3-phosphate, 4 nitrophenyl phosphate, phosphocreatine, and 3-phospho-D-glycerate

May 1, 2009
Author(s)
Robert N. Goldberg, Brian E. Lang, Catherine T. Lo, David J. Ross, Yadu D. Tewari
Microcalorimetry, high-performance liquid chromatography, and an enzymatic assay have been used to conduct a thermodynamic investigation of five phosphate hydrolysis reactions: α-D-galactose 1 phosphate(aq) + H2O(l) = D-galactose(aq) + orthophosphate(aq)
