High‐Energy Al/CuO Nanocomposites Obtained by DNA‐Directed Assembly

“…Indeed, maximal performances were obtained using an electrostatic NP assembly of Al and Fe 2 O 3 , yielding a comparable heat of reaction of 1800 J g −1 , which is 46 % of the theoretical value. [37] Our results also outperformed the results obtained by physically mixed Al/MoO 3 nanothermite, [38] or by multilayered Al/CuO nanothermite, [39] both methods yielding a heat of reaction of 1200 J g −1 . We have also demonstrated that the onset temperature was reduced from 470 °C to 410 °C using the 80 nm Al NPs instead of the 120 nm NPs.…”

Nanoenergetics as pressure generator for nontoxic impact primers: Comparison of Al/Bi2O3, Al/CuO, Al/MoO3 nanothermites and Al/PTFE

“…Nanothermites also open the perspective to fabricate smaller weapon systems or higher lethality weapon. Moreover, compared to conventional explosives, one asset of nanoenergetic materials is the possible adjustment of the energy density, power release and pressure generation by a suitable choice of fuels, oxidizers, material geometries and reactant compaction [3,[14][15][16][17][18][19][20][21][22]. Until recently, very few reports have considered the dynamic pressures developed by the gas expansion during nanothermites reactions [11,[23][24][25].…”

Assembly and reactive properties of Al/CuO based nanothermite microparticles

“…More sophisticated assembly methods include, sputtering [1,[20][21][22], arrested reactive milling (ARM) [2,23,24], electrostatic directed assembly [25], and sol-gel synthesis [26,27]. In recent years, self-assembly approaches have been employed to precisely engineer three-dimensional structural nanothermites [28].…”
