  • Homogeneous mesoporous nanoenergetic metal oxide composite fabrication methods
    Patent number: 8512490
    Abstract: The invention provides methods for making homogeneous metal oxide nanoenergetic composites. A method of the invention forms a metal oxide nanostructure via a sol-gel process with surfactant templating. Metal nanoparticles are introduced into the metal oxide nanostructure via wet impregnation.

  • NANOTHERMITE THRUSTERS WITH A NANOTHERMITE PROPELLANT
    Publication number: 20110167795
    Abstract: In various embodiments, the present disclosure provides a thruster that utilizes a nanothermite material as a propellant. The thruster generally includes a body having at least one sidewall and a bottom wall that define a propellant chamber having a closed repulsion end and an opposing open exhaust end. The thruster additionally includes a nanothermite propellant configured within the propellant chamber to have a selected density that dictates a reaction propagation rate of the nanothermite propellant such that the reaction propagation rate will have a selected one of two distinctly different force-time profiles.

  • On-chip igniter and method of manufacture
    Patent number: 7608478
    Abstract: A chip for igniting nanoenergetic materials, includes a substrate, an igniter positioned on the substrate and the nanoenergetic material arranged in a linear pattern positioned on said substrate. A method of making a chip for igniting nanoenergetic materials includes providing a substrate, forming an igniter on the substrate and coating the substrate with a polymer layer. A pattern of nanoenergetic material comprising a fuel and an oxidizer is formed on the substrate. The nanoenergetic material is ignited by the igniter by supplying power to the leads attached to the heater film.
