LABORATORY FILTER MEDIA

June 1, 2016
Author(s)
Thomas J. Bruno
Filtration is the physical separation of a component or components (which may be solid, liquid, gel, etc.) from a matrix stream (which is usually a fluid), without causing any other changes such as chemical reactions. In the laboratory, filtration is most

Summary of results from the 2014/2015 Hydrocarbon Intercalibration Experiment (HIE)

May 27, 2016
Author(s)
Christopher Reddy, Stephen Wise, Lane C. Sander, Jacolin Murray
Following an open meeting entitled, "Hydrocarbon Chemistry QA/QC," at the 2014 Gulf of Mexico Oil Spill and Ecosystem Science Conference in Mobile, Alabama, the Gulf of Mexico Research Initiative (GoMRI) initiated the Hydrocarbon Intercalibration

Towards a dynamic pressure standard based on laser absorption spectroscopy

May 20, 2016
Author(s)
Kevin O. Douglass, Douglas A. Olson
We describe an approach for creating a cost-effective, field deployable dynamic pressure standard based on measurement of fundamental quantum properties of molecular systems. From the linewidth and intensities of ro-vibrational transitions we plan on

Predicting Structures of Ru-Centered Dyes: A Computational Screening Tool

March 16, 2016
Author(s)
Lisa A. Fredin, Thomas C. Allison
Dye-sensitized solar cells (DSCs) represent a viable means for harvesting solar energy to produce electrical power. Though a number of light harvesting dyes are in use, the search continues for more efficient and effective compounds to make commercially

Method Validation and Standards in Hydrogen/Deuterium Exchange Mass Spectrometry

March 1, 2016
Author(s)
Jeffrey W. Hudgens, Richard Y. Huang, Emma D'Ambro
The chapter examines method validation and measurement standards for measuring protein dynamics by hydrogen/deuterium exchange mass spectrometry. Topics examined include the rationale for a reference measurement system for HDX-MS, attaining high accuracy

Thermodynamic Properties of Polycyclic Aromatic Hydrocarbons

December 16, 2015
Author(s)
Thomas C. Allison, Donald R. Burgess Jr.
Polycyclic aromatic hydrocarbons (PAHs) are molecules that exist on earth due to natural and man-made causes. They are a significant health concern as many PAH compounds are known to be carcinogenic. PAHs are generally thermodynamically stable and

Particle Fabrication Using Inkjet Printing onto Hydrophobic Surfaces for Optimization and Calibration of Trace Contraband Detection Sensors

November 24, 2015
Author(s)
John G. Gillen, Marcela N. Najarro, Matthew E. Staymates, Scott A. Wight, Marlon L. Walker, Jennifer R. Verkouteren, Eric S. Windsor, Aaron A. Urbas
A method has been developed to fabricate patterned arrays of micrometer-sized monodisperse solid particles of ammonium nitrate on hydrophobic silicon surfaces using inkjet printing. The method relies on dispensing one or more microdrops (typically 50 pL
