Amino acid formation induced by high-power laser in CO2/CO-N2-H2O gas mixtures

Authors: S. Civiš, L. Juha, D. Babánková, J. Cvačka, O. Frank, J. Jehlička, B. Králiková, J. Krása, P. Kubát, A. Muck, M. Pfeifer, J. Skála, J. Ullschmied In a mixture of molecular gases with compositions (CO2–N2–H2O and CO–N2–H2O) and total pressure close to that of the EarthÕs early atmospheres, a centimeter-sized plasma was created by focusing a single 85-J, 450-ps…

High Energy Radical Chemistry Formation of HCN-rich Atmospheres on early Earth

Authors: M. Ferus, P. Kubelík, A. Knízek, A. Pastorek, J. Sutherland, S. Civiš Recent results in prebiotic chemistry implicate hydrogen cyanide (HCN) as the source of carbon and nitrogen for the synthesis of nucleotide, amino acid and lipid building blocks. HCN can be produced during impact events by reprocessing of carbonaceous and nitrogenous materials from both the impactor and the…

Radiolysis of methanol vapour

Authors: J. H. Baxendale, R.D. Sedgwick The yields of hydrogen, formaldehyde, ethylene glycol, methane and carbon monoxide from the radiolysis of methanol vapour have been measured and also those of H2 and HD from CH3OD. These have been correlated with the ions observed in the mass spectra. Benzene decreases the yields of hydrogen and formaldehyde and the effect is attributed…
