Abstract

Description

    BRIEF DESCRIPTION OF THE DRAWING
  • Fuel is encapsulated with a polymeric shell and metallic nanoparticles are incorporated into this shell. The small black circles within the polymer shell are the metallic nanoparticles in the figure. A laser then supplies irradiation to initialize the burning of a single fuel droplet and release heat.
    • DETAILED DESCRIPTION OF THE INVENTION
  • A microencapsulation and nanoencapsulation technology that allows fabrication of emulsion of liquid fuel (for instance benzene, sunflower oil and other water non-mixable hydrocarbons of different sort). Size of emulsion droplet is about 0.5-10 microns and can be optimized. Each emulsion drop is coated with polymer based multilayer films. The fuel and coating is referred to as a Capsule. Ceramic nanoparticles (metal, magnetic) should be incorporated as droplet shell constituents within polymeric films. Metallic nanoparticles are susceptible to laser irradiation and produce some heat locally to initialize burning of fuel. Oxidizer must be supplied from external media (could be permanganate dissolved water and other oxidizers) for continuous burning of fuel. Laser beam is conducted via optical waveguide to the chamber containing fuel droplets. Burning of fuel droplets can be done continuously one by one since each impulse of laser power is enough to burn individual droplet. See FIG. 1. Released energy can be consumed by heating of water if fuel emulsion is suspended in water.
  • Alternatively, the emulsion droplet can be arranged on surface in a closed air chamber. Laser power focusing on each capsule with fuel can release energy within the air chamber that can be utilized either in heating or pressure and mechanical movement. Emulsion shell can be modified with magnetic nanoparticles. Thus, if necessarily, the fuel droplets can be navigated with a magnetic field within the media to a certain location where release of energy is required.
  • Burning of the capsule can initialize a further reaction with higher temperature increase. Aluminium powder (thermite) with the oxidizer (permanganate) can be deposited close to the fuel droplet. Burning of fuel droplet will lead to thermite reaction (oxidation of aluminum) with extremely high temperature release (up to 2000° C). Aluminum powder in the form of a nanoparticle can be incorporated into a fuel droplet that will form a micro-packaged high capacity fuel.
  • Potential use:
      • Medical heating inside the human body to inhibit bleeding
      • Micronized internal combustion devise
      • Controlled and sustained heat release within closed chamber
      • Micron mechanical systems
      • Controlled supply of fuel into fuel cell devices
      • Sintering/pressuring on microscale
