A pyrotechnic delayed-action composition and primer charge made of REACh-compliant components that are safe for humans and the environment. The delayed-action composition comprises at least one oxidant, at least one reducing agent, at least one filler and at least one mineral binder. The performance parameters thereof, in particular the burning time, can be set variably within a wide range. The composition clinkers on its own, thus preventing extinction at the front of the burning material even in dynamic conditions. The primer charge comprises at least one oxidant, at least one reducing agent, at least one filler and at least one mineral binder. It is easy to ignite and, due to its clinker structure, transfers its energy well to the compositions to be ignited. The delayed-action composition and the primer charge have the same structure and can easily be combined and adapted to each other in delayed-action units.

Ammunition for a toy blaster may be infused with or otherwise contain a bittering agent, such as denatonium benzoate. Addition of denatonium benzoate to ammunition formulations may reduce the likelihood that the ammunition may be ingested by children. Ammunition may be formed of a superabsorbent polymer or hydrogel. By introducing a non-toxic bittering agent into the superabsorbent polymer or hydrogel that may form the ammunition, it may be more likely that children may spit out the ammunition instead of swallowing the ammunition. Denatonium benzoate may comprise approximately 50 parts per billion of the superabsorbent polymer or hydrogel, but may comprise approximately 1 to 100 ppb. When used in these low concentrations, the ammunition may be safe for a child to put in his/her mouth, but given the taste of denatonium benzoate, its inclusion as part of the ammunition formulation may act as an aversive agent.

A high density, generally recognized as safe hybrid rocket motor is described which has a density-specific impulse similar to a solid rocket motor, with good performance approaching or equal to a liquid rocket motor. These high density hybrid motors resolve the packaging efficiency/effectiveness problems limiting the application of safe, low cost hybrid motor technology.

A solid rocket motor includes a first solid propellant and a second solid propellant at least partially surrounding the first solid propellant. The second solid propellant is resistant to fragment impact and the first solid propellant has a higher impulse than the second solid propellant.

Energetic compositions and methods of forming components from the compositions are provided. In one embodiment, a composition includes aluminum, molybdenum trioxide, potassium perchlorate, and a binder. In one embodiment, the binder may include a silicone material. The materials may be mixed with a solvent, such as xylene, de-aired, shaped and cured to provide a self-supporting structure. In one embodiment, one or more reinforcement members may be added to provide additional strength to the structure. For example, a weave or mat of carbon fiber material may be added to the mixture prior to curing. In one embodiment, blade casting techniques may be used to form a structure. In another embodiment, a structure may be formed using 3-dimensional printing techniques.

The present invention relates to a water-based non-sensitized matrix or explosive suspension which itself has a rheological behavior such that it allows mechanically loading upward boreholes. This suspension behaves like a viscous liquid when it is forced to flow due to the action of a loading pump, and, however, has the characteristics of a soft solid when it is on standby once inside the borehole. The composition essentially consists of an aqueous solution of oxidizing salts and optionally water-soluble fuels and/or sensitizers, and one or more water-soluble polymers conferring the desired rheological characteristics. Particles of oxidizing salts with a grain size such that they enhance the rheological behavior characteristic of the suspension are dispersed in this aqueous solution.

A capsule can include a shell that defines at least a portion of a chamber; and a mixture of an explosive and a thermally conductive material disposed in the chamber. A method can include forming a mixture of an explosive and a thermally conductive material; disposing at least a portion of the mixture in a chamber of a capsule; and at least partially sealing the chamber.

A method of irradiating a target region containing at least one fullerene comprising molecule promotes the heating or combustion of the target region. The heating method can be employed in a variety of applications including: selective targeting and destruction of cancer cells, detonation of explosives, ignition of a combustible mixture, photolithographic processes, and writing of optical storage media.

A nanoenergetic material composite having a remote ignition characteristic by a high-power pulsed laser beam is prepared by adding various contents of multiwalled carbon nanotubes (MWCNTs) to a nanoenergetic composite material (nEM) to enable remote ignition by a high-power laser beam. The nanoenergetic material composite is a MWCNT/nEM composite powder prepared by adding multiwalled carbon nanotubes to the nanoenergetic material, which is a mixture of fuel material nanoparticles and metal oxidizer nanoparticles, wherein the multiwalled carbon nanotubes enhance a combustion rate of the MWCNT/nEM composite powder by delivering thermal energy upon remote optical ignition by the high-power pulsed laser beam.
