Cyclization and decomposition of nitroguanylazide in organic solvents

When nitroguanylazide is heated in solution, it may cyclize to form a mixture of 5-nitroaminotetrazole and the diammonium salt of 5-nitroaminotetrazole or it may decompose, depending on the nature of the organic solvent.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 7, 945–946, July, 1987.     

Multiwall carbon nanotubes and their applications

The chemical, electrophysical, magnetic, tribological, and physicomechanical properties of multiwall carbon nanotubes (MWCNTs), as well as the characteristics of new nanocomposites and instruments thereof were discussed. These MWCNTs are produced by unique technology and are free from impurities of other carbon modifications. Advantages of multiwall over single-wall carbon nanotubes were demonstrated for applications in electronic devices and preparation of nanocomposites (as filling agents).
