Nanothermite colloids: A new prospective for enhanced performance
Defence Technology, 2019 Nanothermites (metal oxide/metal) can offer tremendously exothermic self sustained reactions. CuO is one of the most effective oxidizers for naonothermite applications.

Quo Vadis, Nanothermite? A Review of Recent Progress. [PDF]
Materials (Basel), 2022 One of the groups of pyrotechnic compositions is thermite compositions, so-called thermites, which consist of an oxidant, usually in the form of a metal oxide or salt, and a free metal, which is the fuel. A characteristic feature of termite combustion reactions, apart from their extremely high exothermicity, is that they proceed, for the most part, in ...

Three-dimensionally Ordered Macroporous Structure Enabled Nanothermite Membrane of Mn2O3/Al. [PDF]
Sci Rep, 2016 Mn2O3 has been selected to realize nanothermite membrane for the first time in the literature. Mn2O3/Al nanothermite has been synthesized by magnetron sputtering a layer of Al film onto three-dimensionally ordered macroporous (3DOM) Mn2O3 skeleton.

Combustion characteristic and aging behavior of bimetal thermite powders
Defence Technology, 2021 Nanothermites have been employed as fuel additives in energetic formulations due to their higher energy density over CHNO energetics. Nevertheless, sintering and degradation of nanoparticles significantly limit the practical use of nanothermites. In this

Afterburn modeling of nanothermite composites [PDF]
AIP Conference Proceedings, 2020 The Jones-Wilkins-Lee (JWL) EOS is widely used to capture detonation energy release but not the energy release from secondary combustion, or afterburn. To account for the burn mechanism of detonation products with that of combustion, the JWL EOS had been extended such as in the work of Miller[1], whose reactive flow model for highly non-ideal ...

Advanced Functional Materials, Volume 33, Issue 49, December 1, 2023., 2023 A multi‐material aerosol jet printing system is introduced for the in situ mixing of a nanoscale thermite comprised of aluminum and copper (II) oxide particles. The high resolution patterning enables precise integration with printed electronics, exemplified by an energetic antenna tuned to 2.45 GHz with low ignition delay, while the digital control ...
