Abstract: Compositions comprising magnesium nanoparticles, a nanoscale metal or metalloid, and an oxidizer and methods of fabrication the compositions are described. One example use of such compositions is in high energy fuel applications. One example method includes fabricating a composite by adding magnesium nanoparticles to a composition of a nanoscale metal or metalloid and an oxidant. Examples of the composition resulting from the described processes provides shorter burn times and a multi-fold increase in reactivity compared to the corresponding composition comprising the same amount of nanoscale metal or metalloid and oxidizer but without the magnesium nanoparticles.

Abstract: A method, a system, and a non-transitory computer-readable medium for controlling flammability of a fuel. The method includes applying a voltage across a nonvolatile ionic liquid to convert the nonvolatile ionic liquid into a flammable liquid; and removing the applied voltage across the nonvolatile ionic liquid to revert the flammable liquid back to the nonvolatile ionic liquid.

Abstract: A method and system are disclosed of assembling metal particles into nanoparticles. The method includes electromagnetically levitating the metal particles; inductively heating the electromagnetically levitated metal particles beyond their melting point into metal droplets; and wherein an evaporation flux achieved at a surface of the metal droplets result in a supersaturation of metal atoms around the metal droplets leading to nucleation and growth of the nanoparticles.

Abstract: An energetic composition and a method of unzipping polymer binders are disclosed, which includes localizing a heat feedback just near the reaction front by unzipping polymer binders employed to a nanothermite. The energetic composition includes an unzipping polymer binder employed to high load fuel and oxidizer particles.
