Abstract: Lead-free primary explosives of the formula [MII(A)R(BX)S](CY)T, where A is 1,5-diaminotetrazole, and syntheses thereof are described. Substantially stoichiometric equivalents of the reactants lead to high yields of pure compositions thereby avoiding dangerous purification steps.
Abstract: The present invention relates to a thin film structure based on an epitaxial (111)-oriented rare earth-Group IVB oxide on the cubic (001) MgO terminated surface and the ion-beam-assisted deposition (“IBAD”) techniques that are amendable to be over coated by semiconductors with hexagonal crystal structures. The IBAD magnesium oxide (“MgO”) technology, in conjunction with certain template materials, is used to fabricate the desired thin film array. Similarly, IBAD MgO with appropriate template layers can be used for semiconductors with cubic type crystal structures.
