We are developing new energetic structures expected to have superior insensitivity characteristics and superior performance characteristics relative to currently used insensitive high explosives. The chemical structures proposed herein are a series of zeroto low-hydrogen-content, polynitro, polycyclic heteroaromatic compounds based on novel nitrogenous heterocycles. By analogy to other nitrated...

High nitrogen energetic materials with astonishing thermal behaviors and performances were synthesized by different metathesis reactions. Particularly the new compound triaminoguanidinium 1-methyl-5-nitriminotetrazolate (TAG-1-Me-AtNO2, 4) shows great explosion performance and may be an alternative to commonly used and toxic RDX. An improved synthesis for the promising energetic compound 4 is a...

The fundamental processes in shock-induced instabilities of materials remain obscure, particularly for detonation of energetic materials. We simulated these processes at the atomic scale on a realistic model of a polymer-bonded explosive (3,695,375 atoms/cell) and observed that a hot spot forms at the nonuniform interface, arising from shear relaxation that results in shear along the interface ...

Nitrogen-rich polymers were synthesized by radical polymerization using the reaction of 5aminotetrazole with methacryloyl chloride and acryloyl chloride, respectively. The nitrogen content of poly(methacrylamidotetrazole) and poly(acrylamidotetrazole), as well as the energetic character of these compounds was increased by nitration of the amido moiety. The products remained however insensitive ...

The oxidation of 1,1-dimethylhydrazine with aqueous monochloramine yielded (E)-1,1,4,4-tetramethyl-2-tetrazene (1) as a pale yellow liquid with hypergolic properties. 1 can be oxidized with potassium permanganate to form (E)-1-formyl-1,4,4-trimethyl-2-tetrazene (2) and (E)-1,4-diformyl-1,4dimethyl-2-tetrazene (3). Additionally, 1 reacts with a diethyl ether solution of monochloramine to form a ...

In recent years the development of new holographic memories based in photopolymers have a great goal. A new commercial holographic memories has been optimized by Aprilis and Inphase. The advantages of this type of materials to store information are well know: their high capacity and their fast random access. In the behaviour of this type of material two important factors determinate the quality...
