REACTIVITY OF NANOTHERMITS WHEN IGNITION BY A HOT BODY
Южно-Сибирский научный вестник, 2023Наноразмерные энергетические композиты, также известные как метастабильные межмолекулярные композиты, представляет собой захватывающий новый класс энергетических материалов. Примерами наноразмерных термитов являются частицы металлов и оксидов металлов размером от 30 до 200 нанометров. Эти материалы могут найти широкое применение, в том числе, в составе

Atomic-Scale Origin of Facet- and Fuel-Dependent Interfacial Evolution in Al/Mg-CuO Nanothermites.
ACS Applied Materials and InterfacesUnderstanding atomic-scale interactions at metal/oxide interfaces is crucial for tailoring the reactivity and stability of nanothermite. In this work, density functional theory (DFT) and ab initio molecular dynamics (AIMD) were employed to investigate ...

The Effects of Confinement on the Fracturing Performance of Printed Nanothermites
Propellants, Explosives, Pyrotechnics, 2018AbstractNanothermites have shown the potential to controllably fracture substrates in applications such as electromechanical systems security. In prior work, both equivalence ratio and material formulation have been varied to tailor fracturing performance.

Thermo-Kinetic Study of Core-Shell Nanothermites
AIP Conference Proceedings, 2006This article presents the formulation of a new nano‐thermite mixture (Al/KMnO4) for application in energetic materials. Reactivities of different thermite mixtures have been compared by a constant volume combustion experiment and the results indicate that the reactivity of the new formulation is two orders of magnitude greater than the traditional ...

Detailed Chemical Kinetic Models for Nanothermites Combustion
Propellants, Explosives, Pyrotechnics, 2018AbstractThe development of nanothermites and the understanding of their behaviors need several improvements in many domains including thermochemistry and chemical kinetics. In this paper a brief state of the art is presented in these fields and possible approaches are presented.
