An engineered composite system designed to be passive or inert under one set of conditions, but becomes active when exposed to a second set of conditions. This system can include a dissolving or disintegrating core, and a surface coating that has higher strength or which only dissolves under certain temperature and pH conditions, or in selected fluids. 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, but which can be stored and used for long periods of time without degradation.

A nanoparticle of a decomposition product of a transition metal aluminum hydride compound, a transition metal borohydride compound, or a transition metal gallium hydride compound. A process of: reacting a transition metal salt with an aluminum hydride compound, a borohydride compound, or a gallium hydride compound to produce one or more of the nanoparticles. The reaction occurs in solution while being sonicated at a temperature at which the metal hydride compound decomposes. A process of: reacting a nanoparticle with a compound containing at least two hydroxyl groups to form a coating having multi-dentate metal-alkoxides.

The explosive device additionally includes explosive material that has been deposited on the surface of the substrate in the vacuum chamber by way of physical vapor deposition (PVD), wherein the explosive material is deposited on the portion of the surface of the substrate subsequent to the surface energy of the portion of the surface of the substrate being modified from the first surface energy to the second surface energy.

A formulation and methods for making high energy organic fuels that incorporate suspended metal particles with metal particle sized ranging from 33 nm to 5 micron. The hybrid organic fuels contain superior density and/or energy content to conventional liquid organic fuels. These hybrid organic fuels used in combination with metal particle afford fuels with 5 to 80% more net heat of combustion (based on volume). These fuels should extend the distant range for jets, liquid rocket engines, SCRAM jet engines, and improve energy content in fuel-air explosive applications such as fuel-air explosives and in the Multi-Effects Weapons System (MEWS) where the fuel is used both for propulsion and explosive effects.
