Production Of Abiotic Or Biogenic Hydrocarbons On Rock Particles In The Presence Of H2O And Carbon Compounds
Abiotic H2 and hydrocarbons are found in fluids discharged from ultramafic-hosted hydrothermal vents. Beneath the hydrothermal vents, abiotic H2 and hydrocarbons can be formed by serpentinization reactions and Fischer–Tropsch-type hydrocarbon-forming […]

Processing of Hydrocarbon Dust In Star-forming Galaxies Revealed With AKARI
Hydrocarbon dust is one of the dominant components of interstellar dust, which mainly consists of polycyclic aromatic hydrocarbons and aliphatic hydrocarbons. While hydrocarbon dust is thought to be processed in […]
