Abstract: A container, such as a bottle or jar, that includes a closed compartment and an active insert device for pressurizing the closed compartment. The active insert device comprises an elastic liner and an active insert that are affixed to a closure or cap or the container. The active insert includes at least one reactant that is triggered to a reaction by an external energy source. The reaction produces a gas, which is delivered to the closed compartment via the liner. The gas causes the liner to expand and open a passage to deliver the gas to the closed compartment.

Abstract: A container comprising a compartment and a closure, which hermetically seals the compartment. The closure comprises an active insert device that comprises one or more reactants that when initiated enter into a diazotization reaction produces nitrogen gas which is delivered to the compartment to increase the pressure of the compartment. The active insert device includes a filter that filters the gas and a vent port through which the gas is delivered to the compartment. A seal opens and closes the vent port based on a pressure difference between the compartment and the vent port side of the seal.

Abstract: A process for the preparation of an energetic nitrate ester compound and related intermediates is provided.

Abstract: Nanoporous metal foams are prepared by ignition of high nitrogen transition metal complexes. The ammonium salts of iron(III) tris[bi(tetrazolato)-amine], cobalt(III) tris(bi(tetrazolato)amine), and high nitrogen compounds of copper and silver were prepared as loose powders, pressed into pellets and wafers, and ignited under an inert atmosphere to form nanoporous metal foam monoliths having very high surface area and very low density.

Abstract: A low-smoke pyrotechnic composition comprising nitrocellulose; nitroguanidine; an oxidizing agent; and, at least one of a flame coloring agent and metal powder, and a method of processing the same is disclosed.

Abstract: A process of preparing bis-(1(2)H-tetrazol-5-yl)-amine monohydrate is provided including combining a dicyanamide salt, an azide salt and water to form a first reaction mixture, adding a solution of a first strong acid characterized as having a pKa of less than about 1 to said first reaction mixture over a period of time characterized as providing a controlled reaction rate so as to gradually form hydrazoic acid without loss of significant quantities of hydrazoic acid from the solution while heating the first reaction mixture at temperatures greater than about 65° C., heating the resultant reaction mixture at temperatures greater than about 65° C. for a period of time sufficient to substantially completely form a reaction product, treating the reaction product with a solution of a second strong acid to form a product of bis-(1(2)H-tetrazol-5-yl)-amine monohydrate, and, recovering the bis-(1(2)H-tetrazol-5-yl)-amine monohydrate product.
