Molecular Beam Studies of Reactions Between Warfare Agents Simulants and Solid Surfaces
Abstract
Our experimental studies are directed at elucidating the mechanisms of interfacial adsorption, desorption, and reactions in collisions between chemical warfare simulants and solid surfaces. The investigations are facilitated by using molecular beam scattering from well characterized, MgO surfaces and model self-assembled monolayer or multilayer surfaces. Much of our efforts for this funding period have been focused on constructing a state-of-the-art ultrahigh vacuum gas-dosing instrument, synthesizing new MgO nano-structured materials, and exploring uptake in new silicon-oxide thin films. The instrument is now complete and enabling us to measure gas-surface reaction probabilities and branching ratios, determine surface adsorbate concentrations and structures, and measure the residence times and bonding energies of molecules on or within a material.
