A mixture and method of creating the mixture includes mixing hexachloroethane, stannous oxide, and aluminum together. The mixture may be loaded into at least one canister. The mixture may be combusted to create a smoke screen. The loading of the mixture into the at least one canister may include pressurized loading at loading pressures in the range of approximately 2300 psi to 3600 psi. The hexachloroethane may include approximately 30-40 parts by weight of the mixture and have a particle size of approximately less than 850 m. The stannous oxide may include approximately 55-65 parts by weight of the mixture and have a particle size of approximately less than 150 m. The aluminum may include approximately 5-10 parts by weight of the mixture and have a particle size of approximately less than 45 m. The mixture is devoid of zinc chloride.

The present invention generally concerns a method for isolating nanoparticles via the decomposition of a ternary metal hydride. More specifically, the present invention harnesses increased energy densities from two distinct nanoparticles isolated by a precise decomposition of LiAlH.sub.4. The singular material is air stable and is a nanocomposite of Li.sub.3AlH.sub.6 nanoparticles, elemental Al nanoparticles, an amount of Ti metal, and a nanoscale organic layer, which we call nMx. The nanocomposite protects and preserves the high energy densities of the core metals isolated from the controlled reaction and makes the nanoparticles safe to handle in air. The final composite is devoid of byproducts or phase transitions that will decrease the energy output of the nanocomposite. The method of the present invention creates a narrow distribution of nanoparticles that have unique burning characteristics useful for many applications.

An expandable, exothermic gel-forming composition that is predominately useful in the consumer products and medical industries. More particularly, it relates to the use of expandable particulate exothermic gel-forming compositions with efficient and long-lasting heat production for heating surfaces and objects without the need for electricity or combustible fuel.

A setting tool for deploying a downhole tool within a wellbore is described herein. The setting tool uses an in situ non-explosive gas-generating power source to generate high-pressure gas, which drives a mechanical linkage to actuate the deployment of the downhole tool. According to certain embodiments the non-explosive gas-generating setting tool contains no hydraulic stages and may contain only a single piston. The setting tool may be fitted to provide different stroke lengths and can provide usable power over a greater percentage of its stroke length, compared to setting tools using explosive/pyrotechnic power sources. Methods of using a non-explosive gas-generating setting tool to deploy a downhole tool within a wellbore are also disclosed.

Disclosed are a nanoenergetic material composite-based solid propellant, a method of preparing the same, and a projectile using the same. The propellant includes: potassium nitrate-sucrose (KNSU) composite powder; and nanoenergetic material (nEM) composite powder in a solid powder form mixed with the KNSU composite powder to prepare a KNSU/nEM propellant. The method includes: preparing KNSU composite powder; preparing nEM composite powder; and preparing a KNSU/nEM propellant by mixing the KNSU composite powder and the nEM composite powder in a solid powder form. The projectile includes: a clay block; a clay nozzle responsible for releasing the pressure generated by explosion of a propellant; and a propellant lamination area disposed between the clay block and the clay nozzle. Upon ignition of the KNSU/nEM propellant, the nEM composite powder increases the combustion rate and combustion temperature of a potassium nitrate-sucrose (KNSU) propellant.
