Biography:
Guillaume THOMAS obtained his PHD in 2015 at the University of Burgundy (Dijon, France), specializing in the synthesis and functionalization of superparamagnetic iron oxide
nanoparticles for medical imaging applications. In 2016, he conducted postdoctoral research at the CEA-Grenoble, where he focused on DNA origami for lithography applications. He joined then the French-German Institute of Saint-Louis as researcher. His current research focuses on the detection of chemical warfare agents, the mechanistic understanding of flash boiling and evaporation phenomena, and the development of innovative energetic materials.
Abstract:
This seminar will present the recent research activities conducted at the NS3E laboratory of the French-German Research Institute of Saint-Louis. This presentation will first introduce the Energetic Materials (EMs), which are high-energy compounds designed for rapid release and used in both civils and military contexts. It will be then explained the imperative to improve their energetic performances, such as detonation velocity and sensitivity, by developing and using an innovative process of recrystallization (Spray Flash Evaporation, SFE). This system allows a fast and continuous production of submicrometric EMs with physicochemical properties well different from raw materials, paving the way to new innovative nanocomposites.
However, the development of this recrystallization process also included a detailed investigation into the role of spray dynamics on particle size, morphology and crystalline structure, findings that will be presented. In addition, the resulting prototypes and derivative applications, such as sensors for trace organophosphorous compounds, are also discussed.
