Boron-based fuels theoretically offer significantly higher volumetric energy densities than conventional liquid fuels. High-energy, amorphous, reactive mixed-metal (Ti–Al–B) nanopowders (RMNPs), produced by a sonochemical reaction, have shown exc

In order to understand the reasons for the apparent benefits of using a flow-blurring (FB) atomizer in a combustion system, it is necessary to first examine fundamental spray characteristics under nonreacting conditions. Previous work on FB atomizers

Thermite reactions with nano-scale particles have attracted much study due to their high flame temperatures and combustion velocities. The mechanism by which the reaction propagates is not well understood. The reaction temperature, the heating rate,
