Fig. 1.From: Optical properties of analogs of Titan’s aerosols produced by dusty plasmaTholins produced by the PAMPRE instrument. (a) Glass vessel coated by tholins (b). Vials filled with different tholins showing a clearer brown color for the tholins when the CH4 ratio increases. The change from dark to clear may be the result of larger grains, or of a lower absorption of the bulk materials in the visible range.Back to article page
