Ultrafast Vibrational Spectrometer for Engineered Nanometric Energetic Materials
Abstract
The proposer requested funding for laser equipment that would be used to study engineered nanometric energetic materials consisting of nanometer metal particles, passivation layers and oxidizing binders. The laser equipment is set up for vibrational sum-frequency generation spectroscopy, which looks at the vibrational transitions of molecules at interfaces between metal particles, their passivation layer and the surrounding oxidizer, in real time while the material is being combusted by a carbon dioxide laser. Interface spectroscopy is crucial because almost all of the relevant chemistry in nanoenergetic materials occurs at interfaces. The needed equipment was ordered and installed, and assembled into a working SFG set up that has been tested on a model system consisting of a self assembled monolayer of alkane on gold. The next step will be to finish integrating the carbon dioxide laser system and to begin looking at aluminum based energetic materials.
