Development of explosive compositions using RAM acoustic technology

The objective is to develop, at the laboratory scale, formulations consisting of one or more energetic molecules and a binder. These materials must match the specifications in terms of performance and insensitivity.
This new process using acoustic waves is an innovative and very promising method for rapidly obtaining new explosive compositions with optimized properties. The work will therefore consist of:
- Conducting a bibliographic review to obtain formulations in granular form using the RAM (resonant acoustic mixing) process.
- Identifying the various process parameters and understanding their influence on the final properties of the mixture.
- Formulating energetic compositions on a laboratory scale that match the specifications.
- Characterizing the materials produced through physicochemical analyses.
- Proposing improvements to optimize the final properties.
- Proposing new applications for RAM in connection with the unit's activities.

Synthesis of high-nitrogen heterocyclic molecules

One of the CEA DAM's objectives is the design of new explosive compositions with optimized properties. As such, the search for new molecules of interest, likely to be integrated into innovative formulations, is a fundamental activity.
The objective of the post-doctorate is to synthesize, on a laboratory scale, energetic molecules with structures capable of meeting the specifications in terms of performance and insensitivity. These are mainly highly nitrogenous heterocyclic molecules (pyrazoles, triazoles, oxadiazoles, etc.). The work will include both the synthesis of intermediates, whether they are considered energetic or not, and that of the final products.
This approach is supported by modeling work carried out upstream, intended to set up tools to propose new structures and evaluate their properties by calculation. This subject will require, in interaction with the modeling team, using these tools and putting them to good use to guide the choice of targets that will be studied experimentally in the laboratory.
