3 million in research funds, and all 14 of these projects will be supported by over $10 million in facility access costs and expertise for experimental neutron and ion irradiation testing, post-irradiation examination facilities, synchrotron beamline capabilities, and technical assistance for design and analysis of experiments through the NSUF.
Ion irradiation lead to irreversible changes in the sample of polyvinylchloride (PVC).
To improve the resistance to weathering ion irradiation is one possible method to reach this objective; however, a systematic study of the effects of high energy electron beam radiation on wood surfaces to influence the weathering behaviour is not available.
The structural and magnetic properties of three different type of core-shell nanoparticles with core as Fe and shell as Fe3O4, Fe3O4/Fe2O3 and Fe3O4/ FeO/Fe3N were investigated for their stability and response under Si+2 ion irradiation.
Specific topics include architecture of thin solid films by the GLAD technique, transparent polymer nanocomposites as a new class of functional materials, nanostructures by ion irradiation, microencapsulation, decorative PVD coatings, microwave chemistry and nanomaterials, aluminum-based nanostructured coatings deposited by magnetron sputtering for corrosion protection of steels, nanolayered hard coatings for mechanical applications, plating of nanocomposite coatings, nanostructured coatings, characterization of coatings, and high temperature oxidation resistance of nanocomposite coatings.
Interestingly we observed the decrease in hardness with decrease in grain size of PVDF thin films upon ion irradiation i.
It also found that the SCS750 processors detected and corrected all single processor errors under heavy ion irradiation, and that power cycling of the processors was never required for correction.
Our recent work has shown that, unlike typical reaction poisons such as S and P, the presence of O and C or C-containing species generated by simple techniques involving electron or ion irradiation has a stabilizing effect on the adsorption (and in-situ formation) of CO on Cu(100) [2].
In the case of the eye tumors, they particularly want to do a comparative study of helium ion irradiation against one of the heretofore standard treatments of the condition, gamma radiation from plaques of iodine-125 surgically implanted behind the affected eye.

DOE will fund over $9 million in facility access costs and expertise for experimental neutron and ion irradiation testing, post-irradiation examination facilities, synchrotron beamline capabilities, and technical assistance for design and analysis of experiments through the NSUF.
Among the topics of invited papers are localized gallium doping and cryogenic deep reaction ion etching in the fabrication of silicon nanostructures, fabricating micro-fluid-channel structures by focused ion-beam techniques, swift heavy ion irradiation induced effects in SiSiOx multi-layered films and nanostructures, quantum and classical molecular dynamics studies of the threshold displacement energy in silicon bulk and nanowire, and ion implantation as surface treatment for osseo-integration.
