Carbon Grains

Listing ID #573909

we are offering Carbon Grains.
The presence of carbonaceous particles, both in circumstellar regions and the interstellar medium, now seems quite well accepted. The exact nature of the carbon grains, however, is still controversial and the subject of a wide and live debate from a theoretical as well as an experimental point of view. Recently in a series of works we have shown that the carbon grains produced and studied in our laboratory may be good candidates as laboratory dust analogs. In particular, by producing and thermally processing fully hydrogenated amorphous carbon grains, we have shown that the heat treatment of the particles can be a reasonable simulation of the grain processing active in space as modeled by other authors. The heat treatment decreases the hydrogen content of the grains which, for this reason, change their internal structure and their optical properties in the 190–260 nm range.
