The Gamma Irradiation of Aqueous Solutions of Urea. Implications for Chemical Evolution

Authors: R. Navarro-González, A. Negrón-Mendoza, E. Chacón 0.05moledm-3,Oz-free aqueous solutions of urea were studies after receiving various doses of 6°Co gamma rays(0.14-600kGy). Urea was found to be relatively stable under radiation; its radiation chemical yield of decomposition was 0.47. Hydrogen (G=0.50), carbon dioxide (G=0.44), ammonia (G=0.22), oxalic acid (G=0.0054), malonic acid (G=0.000064)and three unidentified oligomers were found to be the…

Nitrile gas chemistry in Titan’s atmosphere

Authors: T. Gautier, N. Carrasco, A. Buch, C. Szopa, E. Sciamma-O’Brien, G. Cernogora, This work presents the first study of the gaseous products resulting from the partial dissociation of meth- ane and nitrogen in the PAMPRE experimental setup simulating Titan’s atmospheric chemistry. Using cryogenic trapping, the gaseous products generated from the chemical reactions occurring in the reactor have been trapped….
