The present disclosure addresses limitations in ferritic materials. In at least one aspect, the present disclosure provides core-shell nanoparticles exhibiting improved characteristics for implementations and adoptability in numerous applications. Further aspects of the disclosure provide core-shell nanoparticles for use in electronic, magnetic and electro-magnetic applications. Still, other aspects of the present disclosure provide core-shell nanoparticles for a thermochemical water-splitting reaction resulting in increased Hvolume generation during multiple thermochemical cycles.

Thermally stabilized redox materials and applications thereof

An improved method for the production of pyrophoric materials which does not employ hot NaOH and produces pyrophoric materials on various types of ceramic, metal, nanomaterial substrates. The method impregnates the substrate materials with pyrophoric iron or other materials resulting in materials that are 'tunable' with respect to its pyrophoric output as determined by its temperature, rise time sustenance etc through selective variation of particle size, morphology, and diluents or reactive materials.

A method of generating power uses a nanoenergetic material. The nanoenergetic material comprising thermite is obtained and deposited on a substrate. An igniter is placed on the nanoenergetic material. When power is desired, the nanoenergetic material is ignited. A transducer receives thermal, sonic, magnetic, optic and/or mechanical energy from combustion of the nanoenergetic material and converts it into electrical energy. Preferably, the transducer is a thermoelectric, piezoelectric or magneto device. Preferably, multiple transducers are integrated in one power generators to maximize the power from nanoenergetic thermites.

Shock wave and power generation using on-chip nanoenergetic material

A structured, self-assembled nanoenergetic material is disclosed that includes a nanostructure comprising at least one of the group consisting of a fuel and an oxidizer and a plurality of substantially spherical nanoparticles comprising at least the other of the group consisting of a fuel and an oxidizer. The spherical particles are arranged around the exterior surface area of said nanorod. This structured particle assures that the oxidizer and the fuel have a high interfacial surface area between them. Preferably, the nanostructure is at least one of a nanorod, nanowire and a nanowell, and the second shaped nanoparticle is a nanosphere.

Ordered nanoenergetic composites and synthesis method

The present process for rapidly heating and cooling a target material without damaging the substrate upon which it has been deposited. More specifically, target material is coated onto a first substrate. A self-propagating nanoenergetic material is selected that combusts at temperatures sufficient to change the target material and creates a flame front that propagates sufficiently quickly that the first substrate is not substantially heated. The nanoenergetic material is deposited on the target material, such that the target material and the nanoenergetic material is sandwiched between the substrate and the target material. The nanoenergetic material is ignited and the flame front of the nanoenergetic material is allowed to propagate over the second substrate and change the target material.

Rapid heating with nanoenergetic materials

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.
