Comprehensive Assessment of Composition and Thermochemical Variability of Three Prototype Gas Turbine Fuels by GC/QToF-MS and the Advanced Distillation-Curve Method as a Basis of Comparison for Novel Fuel Development

October 26, 2016

Author(s)

Tara Lovestead, Jessica L. Burger, Nico Schneider, Thomas J. Bruno

Commercial and military aviation is faced with challenges that include high fuel costs, emissions, and supply chain security that result from the reliance on petroleum-based feedstocks. The development of alternative gas turbine fuels from renewable

Evaluation of chemical purity using quantitative 1H-nuclear magnetic resonance

September 28, 2016

Author(s)

Blaza Toman, Michael A. Nelson, Katrice A. Lippa

Chemical purity assessment using quantitative 1H-nuclear magnetic resonance spectroscopy is a method based on ratio references of mass and signal intensity of the analyte species to that of chemical standards of known purity. As such, it is an example of a

in situ methods for monitoring silver nanoparticle sulfidation in simulated waters

September 16, 2016

Author(s)

John M. Pettibone, Jingyu Liu

To probe the transformation pathways of metallic nanomaterials, measurement tools capable of detecting and characterizing the broad distribution of products with limited perturbation is ideal. Thus, we employed a suite of in situ measurements (single

Application of the advanced distillation curve method for the characterization of two alternative transportation fuels prepared from the pyrolysis of polyethylene bags*

September 15, 2016

Author(s)

Thomas J. Bruno, Megan E. Harries, B. K. Sharma, Bidhya Kunwar

The properties of alternative fuels must be evaluated to determine their suitability for use in existing engines, either as blends with conventional petroleum products or as stand-alone substitutions (that is, drop in replacements). Alternative fuels made

Development of Standard Reference Materials to Support Assessments of Iodine Status in Nutrition and Human Health.

August 17, 2016

Author(s)

Stephen E. Long, Brittany L. Kassim, Ashley S. Boggs-Russell, Susan Tai, Stephen A. Wise

Iodine deficiency remains a significant global public health challenge. Analytical measurements are therefore made routinely to assess iodine intake from food and supplements, public health status and trends. The National Institute of Standards and

U.S. domestic cats as sentinels for perfluoroalkyl substances: Possible linkages with housing, obesity, and disease

August 2, 2016

Author(s)

Jessica L. Reiner, Andrew B. Lindstrom, Phillip C. Bost, Janice Dye, Jerry Zweigenbaum, Mark J. Strynar

Perfluoroalkyl substances (PFAS), such as perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), are persistent, globally distributed, anthropogenic compounds. The primary source(s) for human exposure are not well understood although within

Retention behavior of alkyl-substituted polycyclic aromatic sulfur heterocycles in reversed-phase liquid chromatography

July 24, 2016

Author(s)

Walter B. Wilson, Lane C. Sander, M. J. Lopez de Alda, Milton Lee, Stephen A. Wise

Retention indices for 79 alkyl-substituted polycyclic aromatic sulfur heterocycles (PASHs) were determined by using reversed-phase liquid chromatography (LC) on a monomeric and polymeric octadecylsilane (C18) stationary phase. Molecular shape parameters

Retention behavior of isomeric polycyclic aromatic sulfur heterocycles in reversed-phase liquid chromatography

Author(s)

Walter B. Wilson, Lane C. Sander, M. J. Lopez de Alda, Milton Lee, Stephen A. Wise

Retention indices for 70 polycyclic aromatic sulfur heterocycles (PASHs) were determined using reversed-phase liquid chromatography (LC) on a monomeric and a polymeric C18 stationary phase. Molecular shape parameters [length, breadth, thickness (T), and

An azeotropic cross-linked styrene-methacrylate network formed through rapid visible-light photo- polymerization
