N2 - The use of nanotechnology to develop more powerful energetic materials is an exciting and promising new area of research in materials science. Energetic materials based on Al nanoparticles can produce up to twice as much energy as the best molecular explosives. However, the fundamental mechanisms of energetic processes, such as initiation, ignition, and chemical reaction propagation in materials where the metallic fuel components and oxidizer components are inhomogeneously distributed over length scales of tens or hundreds of nanometers, are not yet well understood. Using ultrafast flash-heating techniques combined with time-resolved vibrational spectroscopy, we have studied chemical reactivity of nanoenergetic materials with picosecond time resolution and nanometer spatial resolution.
