It was found that all iodine-containing biocidal energetic materials has a relatively long ignition delay upon combustion. A shorter ignition time (from the thermal trigger to the peak pressure) for Al/iodine oxides might further boost their combustion performance due to their high reactivity and high gas release rate. To achieve this goal, a...

Reactive nanolaminates are a high-energy-density configuration for energetics that have been widely studied for their tunable energy release rates. In this study, we characterized Al/CuO nanolaminate reactions with different fuel/oxidizer ratios and bilayer thicknesses using both macro- and microscale high-speed imaging/pyrometry. Under...

It was experimentally found that silica and gold particles can modify the combustion properties of nanothermites but the exact role of the thermal properties of these additives on the propagating combustion front relative to other potential contributions remains unknown. Gold and silica particles of different sizes and volume loadings were...

This work investigates the combustion of porous Al/CuO thermites, i.e. nanolaminates fabricated with various densities of micron sized air-filled pores in the range of 0-20 vol%. High-speed videography and pyrometry of the high-temperature propagating flame were used to analyze the effect of porosity on propagation velocity. Incorporating...
