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 modification of wood and wood surface properties has been a long tradition and has focused on ion irradiations (e.
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.
