Graduate Theses and Dissertations

Aluminum nanoparticles are of interest due to the variety of their applications, including additives for plastics and powder metallurgy. They can also enhance the burning rate of propellants. Metallic particles in traditional thermites are in the micron size range. When the particle diameter reduces to the nanometer range, their reactivity increases by several orders of magnitude. Thus flame rates of 0.9-1 km/s can be reached, while for micron size thermites they are on the order of centimeters or meters per second. Ignition delay time also decreases by up to three orders of magnitude.

The two main continuum methods ...
