Sputter-deposited Al/CuO multilayers are used to manufacture tunable igniters and actuators with applications in various fields of application such as defense, space and infrastructure safety. This paper describes the technology of deposition and characteristics of Al/CuO multilayers followed by some examples of applications of these energetic layers.

The paper reports a joint experimental/theoretical study on the aging of reactive Al/CuO nanolaminates, investigating both structural modifications and combustion properties of aged systems. We first show theoretically that the long-term storage (over several decades) in ambient temperature marginally affects nanolaminates structural properties...

To reduce the size inconvenience of airbag systems employed in human-body protection devices while maintaining comparable gas generation performance, a new family of gas-generating energetic composites are proposed mixing Al/CuO nanothermite with copper complex (Cu(NH 3) 4 (NO 3) 2) known for its propensity to generate gases (0.03 mol/g) such...

La photocatalyse, à distinguer de la photo-électro-catalyse, permet de produire de l'hydrogène par photo-réduction de l'eau, tout en s'affranchissant de l'utilisation d'électrodes, d'un courant électrique, ou encore de l'utilisation d'un bain électrochimique. [1] Dans ce cadre, nous avons développé un dispositif de panneau solaire hydrogène...
