“…The soot particles sampled on the TEM grids are observed under a JEOL JEM 1011 TEM, which is a tungsten hairpin 100kV electron microscope. The bright field images are acquired as tiff files on a CCD camera Gatan Orius SC 1000 A1 in 2672x4008 pi xel 2 . During observation, it is noticed sample modification under electron beam revealed at least by soot vibration which limited the time of observation.…”

“…Fire safety is a major concern for space exploration [1]. As spaceflights transition from Low Earth Orbit (LEO) to deep space exploration, additional constraints challenge existing tools and protocols [2]. At the heart of the fire safety strategy, detection devices rely heavily on the detection of smoke produced by a fire-like diffusion flame.…”

Finer strategies of spacecraft fire mitigation require more experimental data related to fire detection. Fire detection systems developed on Earth rely massively on the optical detection of soot particles, which are present in the smoke. To detect the fire correctly, it is thus important to know how the optical properties of these particles are affected in reduced gravity. With different transport processes and increased residence time, soot in reduced gravity can be different from those produced at normal gravity. As their optical properties are related to their morphological properties, a better understanding about the evolution of soot particle morphology in flames under microgravity conditions is required. Within this context, a novel technique of soot sampling using electric field is applied to a spreading non-premixed flame at normal
