Hydrogen atoms in radiolysis of liquids, solids and ordered systems: Zeolites and mesoporous solids

Description: Hydrogen atoms are ubiquitous species in radiolysis of many liquid and solid systems. They serve a very important role in passivation of solid-state defects in silica-based devices and there is concern about the role of radiolytic generation of molecular hydrogen in radioactive waste storage. The authors have made extensive studies of H atoms in water, ice and amorphous silica using conventional and time-resolved magnetic resonance. H atoms are exquisite probes of reaction dynamics and phase st… more

Radiation effects on transport and bubble formation in silicate glasses

Description: Advanced Electron Paramagnetic Resonance spectroscopy (pulsed EPR, time-resolved EPR, high-frequency EPR, ENDOR) has been used to structurally characterize metastable point defects in irradiated alkali borate, silicate, and borosilicate glasses and to study mobile interstitial H atoms. In addition, the yield of radiolytic oxygen has been determined by outgassing. Several mechanisms for the defect formation in oxide glasses have been established.
