Campbell, Adam Friss, Lucas Hale, Michael Halter, Robert Hanisch, Gary R. Hardin, Lyle E. Levine, Samantha Maragh, Sierra Miller, Chris Muzny, Marcus William Newrock, John Perkins, Anne L. Plant, Bruce D. Ravel, David J. Ross, John Henry J. Scott, Christopher Szakal, Alessandro Tona, Peter Vallone
Instrumentation generates data faster and in higher quantity than ever before, and interlaboratory research is in historic demand domestically and internationally to stimulate economic innovation. Strategic mission needs of the NIST Material Measurement

CCQM Pilot Study P-140; Quantitative Surface Analysis of Multi-Element Alloy Films

October 1, 2015
Author(s)
David S. Simons, Christopher W. Szakal, William A. Osborn, Kyung Joong Kim
A pilot study for the quantitative surface analysis of multi-element alloy films has been performed by the Surface Analysis Working Group (SAWG) of the Consultative Committee for Amount of Substance (CCQM). The aim of this pilot study is to ensure the

Measurement of Nanomaterials in Foods: Integrative Consideration of Challenges and Future Prospects

April 30, 2014
Author(s)
Christopher W. Szakal, Steve Roberts, Paul Westerhoff, Andrew Bartholomaeus, Neil Buck, Ian Illuminato, Richard Canady, Michael Rogers
Risks and benefits of nanomaterials related to food receive conflicting attention in news media, research, and across expert stakeholder groups internationally. Current nanomaterial analysis is complicated by broad definitions that include traditional food

Visualizing Nanoparticle Dissolution by Imaging Mass Spectrometry

March 10, 2014
Author(s)
Christopher W. Szakal, Melissa S. Ugelow, Justin M. Gorham, Andrew R. Konicek, Richard D. Holbrook
We demonstrate the ability to visualize nanoparticle dissolution while simultaneously providing chemical signatures that differentiate between citrate-capped silver nanoparticles (AgNPs), AgNPs forced into dissolution via exposure to UV radiation, silver

Preparation and Measurement Methods for Studying Nanoparticle Aggregate Surface Chemistry

June 8, 2012
Author(s)
Christopher W. Szakal, James McCarthy, Andrew R. Konicek, Kacie Louis, Benjamin Yezer, Andrew A. Herzing, Robert Hamers, Richard D. Holbrook
Despite best efforts at controlling nanoparticle (NP) surface chemistries, the environment surrounding nanomaterials is always changing and can impart a permanent chemical memory. We present a set of preparation and measurement methods to be used as the
