Fission Gas Transport and Its Interaction With Irradiation Induced Defects in Lanthanum Doped Ceria
… characterize the dose and temperature effects of irradiation. These results also help to benchmark simulation codes being developed with a kinetic Monte Carlo model. These experimental results include size and size distributions of dislocation loops, voids and gas bubble structures created by …

Fission gas transport and its interactions with irradiation-induced defects in lanthanum doped ceria
… have been extremely productive in understanding irradiation-induced displacement damage in metal and metal alloy systems. In order to help understand the fundamental mechanisms of irradiation-induced defect formation and evolution in nuclear fuel, similar combined modeling and experimental …

Low Temperature Electron Irradiation Induced Defects in Gallium-Arsenide: Bulk and Surface Acoustic Wave Studies
Irradiation of GaAs with 2.25 - 2.5 MeV electrons at temperatures below 190 K produces two peaks in ultrasonic attenuation versus temperature. The defects responsible for both peaks have trigonal symmetry and were observed in n-type and semi-insulating GaAs with bulk and surface acoustic waves …

Low temperature electron irradiation induced defects in gallium arsenid: Bulk and surface acoustic wave studies
Irradiation of GaAs with 2.25-2.5 MeV electrons at temperatures below 190 K produces two peaks in ultrasonic attenuation versus temperature. The defects responsible for both peaks have trigonal symmetry and were observed in n-type and semi-insulating GaAs with bulk and surface acoustic waves (SAW) …

Emulating Radiation-Induced Defect Microstructures by Neutrons and Dark Matter Using Ions
… timescale. Emulation involves mimicking neutron-induced defect structures using surrogate particles. The research problem is whether this strategy can be reliably extended to more complex or hypothetical scenarios, such as new reactor designs, load-following regimes, and even direct detection of …

Microbial Safety, Shelf Life Stability, Quality Preservation, and Consumer Acceptance of Vacuum-infused, Irradiated Chicken Breast Meat Treated with Natural Plant Extracts and Organic Acids
… events are still uncomfortably frequent. Irradiation is a safe and effective means of ensuring the safety of both ready-to-cook and ready-to-eat poultry but is not utilized in the United States. This is due, in part, to certain irradiation dose-dependent quality characteristic defects …

Quantifying radiation damage through stored energy released during defect annealing in metals
… unable to detect the smallest and most numerous defects in irradiated metals. Instead of spatial characterisation, defects can be detected and quantified through their excess energy. Previous measurements of stored energy in irradiated metals have been limited to cryogenic or ambient …

Processing and irradiation-driven evolution of refractory microstructures
… service-like conditions (specifically, under irradiation). The broad goal is to understand how underlying mechanisms can drive microstructural development (and subsequently influence material properties and performance) under both these lenses, to help design more robust, optimized …

Engineering Functional Defects in Oxides Using External Stimuli
… often depend strongly on the functional defects of various dimensionalities, such as vacancies, interfaces, and precipitates. Therefore, defect engineering lies at the heart of materials innovations for the next-generation technologies. However, due to the enormous span in the length …

First-principles studies on oxide nanoclusters in bcc Fe
… are used to investigate their ability to trap irradiation defects He, v and SIA. These defects are inserted on different positions inside and in the environment of the clusters, the total energy of the corresponding supercell is minimized by DFT, and the binding and incorporation energy of the …
