Approaches for the Quantitative Analysis of Oxidation State in Cerium Oxide Nanomaterials

September 21, 2018
Author(s)
Christopher M. Sims, Russell A. Maier, Aaron C. Johnston-Peck, Justin M. Gorham, Vincent A. Hackley, Bryant C. Nelson
Cerium oxide nanomaterials (nanoceria, CNMs) are receiving increased attention from the research community due to their unique chemical properties, most prominent of which is their ability to alternate between the Ce3+ and Ce4+ oxidation states. While many

Agglomeration of Escherichia coli with positively charged nanoparticles can lead to artifacts in a standard Caenorhabditis elegans toxicity assay

Jiaojie Tan, Tae Joon Cho, De-Hao Tsai, Jingyu Liu, John M. Pettibone, Rian You, Michael R. Zachariah, Vincent A. Hackley
Cisplatin-complexed gold nanoparticles (PtII-AuNP) provide a promising strategy for chemo- radiation based anticancer drugs. Effective design of such platforms necessitates reliable assessment of surface engineering on a quantitative basis, and its

Quantitative Analysis of Oxidation State in Cerium Oxide Nanomaterials

May 14, 2017
Author(s)
Christopher Sims, Russell Maier, Aaron Johnston-Peck, Justin Gorham, Vincent A. Hackley, Bryant C. Nelson
Cerium oxide nanoparticles (nanoceria) are receiving increased attention from the research community due to the large number and wide range of their current and potential applications. The attractiveness of nanoceria for these various applications is

Reference nanomaterials to improve the reliability of nanoscale measurements

March 1, 2017
Author(s)
Gert Roebben, Vincent A. Hackley, Hendrik Emons
Reference materials are essential tools to assure the quality of measurement results, from R&D labs to production facilities. They help increase the reliability of measurements, as laboratories can use reference materials to verify, for themselves, and
