Preparation of safer reactive nanothermites
, 2022 Safer handling of sensitive energetic materials is the main concern of nanothermites development. These compositions, made from a metal oxide and a metallic fuel, show interesting reactive properties but also an extreme sensitivity to electrostatic discharge leading to make their handling hazardous.

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 ...

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 ...

Group Combustion of Dispersed Spherical Core–Shell Nanothermite Particles
Thermo, 2022 The group combustion characteristics of core–shell nanothermite particles differ from other dispersed solid or liquid fuels. In a core–shell structure, each discrete nanothermite particle can undergo an exothermic reaction as the oxygen atoms in the ...
