Evaluating droplet digital PCR for the quantification of human genomic DNA: converting copies per nanoliter to nanograms nuclear DNA per microliter

February 22, 2018

Author(s)

David L. Duewer, Margaret C. Kline, Erica L. Romsos, Blaza Toman

The highly multiplexed polymerase chain reaction (PCR) assays used for forensic human identification perform best when used with an accurately determined quantity of input DNA. To help ensure the reliable performance of these assays, we are developing a

Semiempirical Configuration Interaction Calculations for RuCentered Dyes

February 18, 2018

Author(s)

Lisa A. Fredin, Thomas C. Allison

Computational investigation of of the photochemical properties of transition-metal-centered dyes typically involves optimization of the molecular structure followed by calculation of the UV/Visible spectrum. At present, these steps are usually carried out

Examining Heat Treatment for Stabilization of the Lipidome

February 16, 2018

Author(s)

John Bowden, Candice Z. Ulmer, Christina Jones, Tracey Johnston, Jeremy P. Koelmel, Timothy J. Garrett, Richard A. Yost

Aim: To confidently determine lipid-based biomarkers, it is important to minimize variation introduced during preanalytical steps. We evaluated reducing variation associated with lipid measurements in invertebrate sentinel species using a state-of-the-art

Reverse and Random Decoy Methods for False Discovery Rate Estimation in High Mass Accuracy Peptide Spectral Library Searches

February 2, 2018

Zheng Zhang, Meghan C. Burke, Yuri A. Mirokhin, Dmitrii V. Tchekhovskoi, Sanford P. Markey, Wen Yu, Raghothama Chaerkady, Sonja Hess, Stephen E. Stein

Spectral library searching (SLS) is an attractive alternative to sequence database searching (SDS) for peptide identification due to its speed, sensitivity, and ability to include any selected mass spectra. However, SLS does not have a widely tested and

AQUEOUS SIZE-EXCLUSION CHROMATOGRAPHY OF POLYELECTROLYTES ON REVERSED-PHASE AND HYDROPHILIC INTERACTION CHROMATOGRAPHY COLUMNS

January 12, 2018

Author(s)

Anna Caltabiano, Joe Foley, Andre Striegel

Size-exclusion separation of a water-soluble polyelectrolyte polymer, sodium polystyrene sulfonate (NaPSS), was demonstrated on common reversed-phase (C18, C4, phenyl, and cyano) and hydrophilic interaction chromatography (HILIC) columns. The effect of

Nanostructured lipid-based films for substrate-mediated applications in biotechnology

January 10, 2018

Author(s)

Minjee Kang, Mohit Tuteja, Andrea Centrone, Daniel Topgaard, Cecilia Leal

Amphiphilic in nature, lipids spontaneously self-assemble into a range of nanostructures in the presence of water. Among lipid self-assembled structures, liposomes and supported lipid bilayers have long held scientific interest for their main applications

Organic Solvent Modifier and Temperature Effects in Non-Aqueous Size-Exclusion Chromatography on Reversed-Phase Columns

January 5, 2018

Author(s)

Andre M. Striegel, Anna Caltabiano, Joe Foley

The effect of THF solvent and the mixtures of THF with a variety of common HPLC solvents (chloroform, acetone, 2-propanol, DMF, ethanol, acetonitrile and methanol) on reversed-phase stationary phase (C18, C4, phenyl and cyano) characteristics relevant to

Determination of nicotine, NNN, and NNK in a new cigarette tobacco filler Standard Reference Material (SRM 3222) and its smoke

January 1, 2018

Author(s)

Walter B. Wilson, Jeanita Pritchett, Lane C. Sander

The United States has an annual production of approximately 800 million pounds of tobacco with estimated domestic sales of around 260 billion cigarettes/year. The National Institute of Standards and Technology (NIST) has recently collaborated with the

Identification of harmful and potentially harmful contaminants in tobacco smoke produced from low- and high-nicotine cigarette tobacco fillers

January 1, 2018

Author(s)

Walter B. Wilson, Lane C. Sander

Under the Food, Drug, and Cosmetic Act (FD&C) all tobacco manufacturers and importers are required to report the levels of harmful and potentially harmful constituents (HPHCs) found in their tobacco products and tobacco smoke. Studies have reported the

FEASIBILITY OF USING THE NATIONAL MARINE MAMMAL TISSUE BANK FOR RETROSPECTIVE EXPLORATORY STUDIES OF PERFLUORINATED ALKYL ACIDS

December 26, 2017

Author(s)

Jennifer M. Lynch, Jared M. Ragland, Amanda J. Moors, Rebecca S. Pugh, Jessica L. Reiner

Perfluorinated alkyl acids (PFAAs) have been used for more than 50 years in materials such as stain-resistant treatments for paper and clothing, lubricants, and foam fire extinguishers. PFAAs are characterized by a fully fluorinated alkyl chain with a

NIST Database for the Simulation of Electron Spectra for Surface Analysis (SESSA), SRD 100, Version 2.1

December 21, 2017

Author(s)

Wolfgang Werner, Werner Smekal, Cedric J. Powell

The objective of the NIST database for Simulation of Electron Spectra for Surface Analysis (SESSA) is to facilitate quantitative interpretation of Auger-electron and X-ray photoelectron spectra (AES/XPS). The database contains physical data required to

Quantitative chemical analysis at the nanoscale using the photothermal induced resonance technique

December 19, 2017

Author(s)

Georg Ramer, Vladimir Aksyuk, Andrea Centrone

Photothermal induced resonance (PTIR) is a scanning probe technique that provides sample composition information with a lateral resolution down to 20 nm. Interest in PTIR stems from its ability to identify unknown samples at the nanoscale thanks, in first
