Ti/CuO Nanothermite—Study of the Combustion Process [PDF]
MoleculesA study of the combustion processes of Ti/CuO and Ti/CuO/NC nanothermites prepared via electrospraying was conducted in this work. For this purpose, the compositions were thermally conditioned at 350, 550 and 750 °C, as selected based on our initial ...

Ti/CuO and Ti/CuO/Cellulose Nitrate Nanothermites: An Early Insight into Their Combustion Mechanism
EnergiesMost nanothermite compositions utilise Al as a fuel, due to its low cost, high reactivity and availability. Nevertheless, aluminothermites exhibit high ignition temperature and low active metal content.

Burning structures and propagation mechanisms of nanothermites
Proceedings of the Combustion Institute, 2022 Nanothermites demonstrate attractive combustion characteristics such as tunable reactivity and high energy density. There is however a lack of fundamental understanding on their burning structures and reaction mechanisms due to the multi-scale complexity associated with the material and reaction heterogeneities.

Nanothermites : synthèse et combustion
Physique Chimie, 2021 Les nanothermites sont des materiaux energetiques prometteurs pour de multiples applications civiles ou militaires en raison de leurs caracteristiques en combustion. Ils peuvent jouer le role d’explosif primaire en remplacement des composes contenant des metaux lourds (azoture de plomb, etc.) a « eliminer » dans le cadre de la reglementation REACH ou ...
