Autor: Audrey Chatain, Ana Sofia Morillo-Candas, Ludovic Vettier, Nathalie Carrasco, Guy Cernogora, Olivier Guaitella

The addition of small amounts of H2 were investigated in a DC glow discharge in N2, at low pressure (~1 mbar) and low power (0.05 to 0.2 W.cm-3). We quantified the electric field, the electron density, the ammonia production and the formation of posi

23 pags., 16 figs., 4 tabs.
In this work, we present the results of simulations carried out for N2 –H2 capacitively coupled radio-frequency discharges, running at low pressure (0.3–0.9 mbar), low power (5–20 W), and for amounts of H2 up to

International audience; The role of polycyclic aromatic hydrocarbons (PAH) and Nitrogen containing PAH (PANH) as intermediates of aerosol production in the atmosphere of Titan has been a subject of controversy for a long time. An analysis of the atmo

A RF CCP plasma discharge in N2/CH4 mixture is used to produce organic films. Here is presented the influence of a cryogenic cooling during the film synthesis on the optical refractive indices. The optical indices in the visible range are determined

International audience; Two sorts of solid organic samples can be produced in laboratory experiments simulating Titan's atmospheric reactivity: grains in the volume and thin films on the reactor walls. We expect that grains are more representative of
