The photolysis and radiolysis of barium azide, with some observations on the photolysis and radiolysis of lithium azide
[Many pages missing] If the respective curves lntersect and the excited state has a minimum lying inside the ,ground state curve, then on optical transition to the excited state wi II be followed by a radiationless transition to the point where the excited and ground state curves intersect. If, …

Radiolysis of the Extract from the Sawdust of the Ponderosa Pine
<p>Portions of an acetone-hexane (1:4) extract of Ponderosa pine sawdust were exposed to gamma and ultraviolet radiation. The three solutions, including the original, were checked for antibiotic activity on: Staphylococcus aureus Escherichia coli and Bacillus cereus. Results indicated that each …

Comparison of the Effects of Cobalt-60 [gamma]-Rays and Tritium [beta][superscript -]Particles on Water Radiolysis and Aqueous Solutions and Radiolysis of the Ceric-Cerous Sulfate Dosimeter at Elevated Temperature
… to be very powerful techniques to study the radiolysis of water and the mechanisms underlying this radiolysis. Monte Carlo simulations particularly become important when there are no experimental results available in the literature due, for instance, to the difficulty of performing such …

Monte Carlo simulation of the radiolysis of water by fast neutrons at elevated temperatures up to 350°C
… and mitigating the effects of water radiolysis to limit the corrosion and degradation of materials by oxidizing radiolysis products. However, direct measurement of the chemistry in reactor cores is extremely difficult due to the extreme conditions of high temperature, pressure, and …

A study of solute transport of radiolysis products in crud and its effects on crud growth on PWR fuel pin
This research examines the effect of radiolysis species (H2, O2, and H2O2) upon crud deposition and growth and also the effect of their concentration within the crud. A 3-D transient diffusion model has been developed to simulate solute transport of these radiolysis products in porous crud layer. …

An Investigation of the Singlet Delta Oxygen and Ozone Yields From the Pulsed Radiolysis of Oxygen and Oxygen-Noble Gas Mixtures
The experiments discussed in this thesis were performed with a flowing gas apparatus coupled to the University of Illinois TRIGA reactor. The detectors ((lamda) = 1.27 microns, 634 nanometers) were calibrated with a novel NO(,2) titration scheme and the absorbed dose was estimated from the ozone …

“Acid-spike” effect in spurs/tracks of the low/high linear energy transfer radiolysis of water : potential implications for radiobiology and nuclear industry
… of the low or high linear energy transfer (LET) radiolysis of pure, deaerated water at early times. The in situ radiolytic formation of H3O+ renders the spur and track regions temporarily more acid than the surrounding medium. Although experimental evidence for an acidic spur has already been …

The Effects of Neutron and Gamma Radiation on Graphene
… is related to the products generated through the radiolysis of the water trapped between the sample and the substrate. By removing the water through evaporation the dopants related to the radiolysis products were found to be removed as well. These results are promising as they show that graphene …

Hydrogen entry in Zircaloy-4 fuel cladding : an electrochemical study
… modeling was used to understand effects of radiolysis and CRUD. Density functional theory (DFT) was used to investigate the role of oxidized Zr(Fe,Cr)2 second phase particles. Chemical potentials and the electron chemical potential were used to connect these two modeling efforts. A …

Reductively triggered internal cyclisation reactions
… have been studied by γ-radiolysis. HPLC methods have been developed for the separation of reduction and cyclisation products. Reduction stoichiometry implicates the hydroxylamine as the predominant reduction product of radiolysis of the 2-nitrophenylalkanamide precursors, …

Enhanced Portability and Anti-Frosting Functionality of Cryostats for Synchrotron-Based X-ray Imaging
… Water within these aqueous samples will undergo radiolysis and produce various reactive oxygen species, which degrades the quality of information gathered from the sample during X-ray imaging. Studies have shown that the best way to counter the effects of radiolysis and preserve samples in their …
