The Effect of a Protein on the Radiolysis of DNA Studied by HPLC and Pulse Radiolysis
International Journal of Radiation Biology and Related Studies in Physics, Chemistry and Medicine, 1987Double-stranded DNA from calf thymus was irradiated in the presence of bovine serum albumin (BSA) with a ratio of 1:10 in weight, at pH7 and pH5, under aerobic and under anaerobic conditions. The irradiated biomolecules were separated by high-performance liquid-gel permeation chromatography.

Radiation Research, 1976
Gamma irradiation of benzonitrile shows that most of the identified products are related structurally to the parent molecule. The gaseous products are hydrogen, acetylene, and hydrogen cyanide. Nitrogen and cyanogen were not detected as products. Other than the gaseous products, benzene was the only product detected with a molecular weight less than ...

Radiolysis of Hexafluoroethane
The Journal of Chemical Physics, 1965The radiolysis of C2F6 at 3-atm pressure has been examined. The products and 100 eV yields are CF4 (1.6), cyclo-C3F6 (0.30), C3F8 (0.21), C4H10 (0.14), and C2F2 (0.03). Good material balance is obtained; the F/C ratio in the products is 3.0. Experiments using radical scavengers indicate that 50% of the CF4 comes from radical reactions and 50% from ...

Selective radiolysis of enantiomers
Radiation and Environmental Biophysics, 1976The gamma-induced decarboxylation of beta-phenylalanine in the solid state is a chain reaction. Both enantiomers and the racemate of beta-phenylalanine-1-14C show different exponential dose-effect curves for the radiation-induced cleavage of 14CO2.

Radiolysis of tetrachloromethane
Journal of the Chemical Society, Faraday Transactions 1: Physical Chemistry in Condensed Phases, 1982Electron spin resonance studies of tetrachloromethane after exposure to 60Co γ-rays at 77 K reveal the formation of ·CCl3 and CCl˙+4 radicals. On warming in the presence of spin-traps, or on irradiating fluid solutions, nitroxide radical adducts have been detected that are characteristic of ·CCl3 and chlorine atom adducts. In the light of this evidence

The Radiolysis of Tributyl Phosphate
Radiation Research, 1958The radiolysis of tri-n-butyl phosphate (TBP) is of interest for several reasons. For one thing, radiation damage to this material is of technical concern, since it is the active ingredient of certain solvent-extraction processes which take place in the presence of strong radiation fields.

Nature, 1966
FEW investigations of the radiolysis of nitroalkanes have been reported1 and, apart from the use of tetranitro-methane as a scavenger in aqueous solutions2, no systematic study of their radiation chemistry has been made. The liquids are highly polar and ionic reactions might be expected to play a significant part in the decomposition processes.

Radiolysis and pulse radiolysis of chlorinated phenols in aqueous solutions
International Journal of Radiation Applications and Instrumentation. Part C. Radiation Physics and Chemistry, 1986Abstract The radiation induced decomposition of 2-, 3- and 4-chlorophenols was studied under steady-state conditions. The rate constants for the reactions of H, OH and e - ag with 2-Cl-phenol were determined. Absorptions spectra of the H- and OH- adducts are presented.

γ-radiolysis and pulse radiolysis of aqueous 4-chloroanisole
Radiation Physics and Chemistry, 1996Abstract Using pulse radiolysis and steady state γ-radiolysis in combination with product analysis by HPLC the radiolytic degradation mechanism of 4-chloroanisole (4-ClAn) has been elucidated. Pulse radiolysis experiments show that OH radicals react in neutral aqueous N2O saturated solutions with 4-ClAn by addition to all aromatic ring positions to ...
