Plasmonic Force Space Propulsion [PDF]
Journal of Spacecraft and Rockets, 2015 Plasmonic space propulsion uses solar light focused onto deep-subwavelength nanostructures to excite strong optical forces that accelerate and expel nanoparticle propellant. Simulations predict that light within the solar spectrum can excite asymmetric nanostructures to create plasmonic forces that will accelerate and expel nanoparticles.

Activated aluminum powders for space propulsion
Powder Technology, 2015 Abstract Aluminum powders are commonly used in solid propellants to enhance the performance of space propulsion systems. During combustion, a fraction of the fuel metal particles, which emerge from the bulk, tends to merge into aggregates. These structures eventually leave the combustion surface in the shape of partially molten agglomerates which can
