Reactions using the high nitrogen heterocycle 3,4,5-triamino-1,2,4-triazole (guanazine) with strong acids (HN03, HCl04, and "HN(N02)2") resulted in a family of highly stable salts. All of the salts were characterized using spectroscopic as well as si

The synthesis and characterization of 1 ,5-diamino- 1,2,3 ,4-tetrazolium perchlorate were carried out. Experimental evidence strongly supports the protonation of a nitrogen atom of the tetrazole ring, including the structure observed in a single crys

The synthesis of three new families of heterocyclic-based salts was undertaken and accomplished. Three triazole systems, 1H-1,2,4-triazole, 4-amino-1,2,4-triazole, and 1H-1,2,3-triazole, were used as proton bases with nitric (HNO3), perchloric (HClO4

Boron nanoparticles prepared by milling in the presence of a hypergolic energetic ionic liquid (EIL) are suspendable in the EIL and the EIL retains hypergolicity leading to the ignition of the boron. This approach allows for incorporation of a variet
