National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Adsorption and Decomposition of CWA Simulants on Single Crystal and Nanostructured Metal Oxides.

ADA517975

Publication Date	2009
Personal Author	Morris, J. R.
Page Count	16
Abstract	Our studies are directed at determining the adsorption mechanisms and reaction pathways for the chemical warfare agent simulant (CWA) for GB (Sarin) on metal oxide surfaces and nanoparticles. By learning about how surface structure, nanoparticle size, composition, and surface co-adsorbates affect the overall interfacial chemistry, we are providing insight that can be applied toward the development of effective sorbent materials for protection and decontamination. Our approach couples ultrahigh vacuum (UHV) surface analysis instrumentation with precision simulant dosing capabilities to explore agent reactivity on highly characterized and contaminant-free metal oxide surfaces. Our work during this funding period has focused on studying the uptake and decomposition of the simulant dimethyl methylphosphonate (DMMP) when it impinges on the surface of nanoparticulate systems.
