A new class of energetic nanoparticles, and a method to produce the same. The energetic nanoparticles are differentiated from other metallic energetic nanoparticles by their core-shell nanostructure including an intermediate boride layer that provides oxidation protection and acts as an active mass. An intermetallic reaction occurs between aluminum and nickel. Aluminum based nanoparticles were used for the examples, but the principle is applicable to other materials as well.

A high strength engineered reactive matrix composite that includes a core material and a reactive binder matrix combined in high volumes and with controlled spacing and distribution to produce both high strength and controlled reactivity. The engineered reactive matrix composite includes a repeating metal, ceramic, or composite particle core material and a reactive binder/matrix, and wherein the reactive/matrix binder is distributed relatively homogeneously around the core particles, and wherein the reactivity of the reactive binder/matrix is engineered by controlling the relative chemistry and interfacial surface area of the reactive components. These reactive materials are useful for oil and gas completions and well stimulation processes, enhanced oil and gas recovery operations, as well as in defensive and mining applications requiring high energy density and good mechanical properties.

The present technology is directed to igniter pellets for use with an expendable countermeasure flare assembly with an igniter assembly with a pellet receptacle. An igniter pellet of one or more embodiments has a moisture insensitive first layer formed by a first composition comprising a mixture of a fuel material that includes Boron, an oxidizer material that includes Bismuth Oxide and/or Potassium Perchlorate, and a granular matrix binder holding the fuel material and the oxidizer material together. A second layer is formed by a second composition that has a fuel material that includes Magnesium, an oxidizer that includes Polytetrafluoroethylene, and a binder material that includes a fluoropolymer elastomer. The second layer is contained in the pellet receptacle and covered by the first layer, so that the second layer is isolated and protected from ambient moisture by the moisture insensitive first layer.
