Abstract:
Trace oxygen contamination of metal fluoride glasses degrades their performance in applications such as optical fibers or x-ray phosphors. Traditional methods for oxygen determination based on reaction with carbon to form carbon monoxide are slow and insensitive. We have used nuclear reaction analysis, in particular the 18O(p, α) reaction, to determine oxygen content in a variety of metal fluorides. Careful choice of the energy of the incident proton eliminates interference from fluorine. Standardless quantification of our measurements yields good agreement with the known oxygen content of mix

Abstract:
Per- and polyfluoroalkyl substances (PFAS) are a group of fluorinated synthetic chemicals that are highly recalcitrant, toxic, and bio-accumulative and have been detected in biosolids worldwide, posing potential risks to humans and the environment. Recent studies suggest that the organic C-F bond in PFAS can be destructed and potentially mineralised into inorganic fluorides during thermal treatment. This study focuses on thermodynamic equilibrium investigations and the fate of fluorine compounds post-PFAS destruction during biosolid thermal treatment. The results indicate that gas-phase fluori

Abstract:
At the limits of nuclear stability, increasing proton-neutron asymmetry leads to a shifting of orbitals from nuclear shell model predictions. In turn this leads to a weakening of shell gaps such as at N = 20, and the emergence of new gaps at N = 14 and 16. To observe this evolution of the structure as the neutron dripline is approached, single-nucleon removal reactions have been employed for oxygen and fluorine isotopes. These reactions are an excellent way of probing the nuclear wavefunction to reveal information on the single-particle content in the wavefunction. Cross sections have been mea

An increase of oxy-gen concentration and its coadsorption with fluorine leads to substantial structural changes in the surface and subsurface layers due to adsorbate penetration into semiconductor.

Abstract Molten fluoride salt coolants are used in several advanced nuclear reactor concepts.

However, pre-oxidation of alloys can be done to create a continuous high quality oxide scale before exposure to the molten fluoride environment.

Abstract:
Ion-assisted deposition (IAD) has been widely studied as a means of improving the properties of optical thin films.1 Metal fluorides are a case in point, with MgF2 in particular being studied by several groups. Oxygen is a major impurity in IAD fluoride films; however, the nature of the oxygen incorporation has remained unresolved. In order to gain insight into the IAD process with metal fluorides, we have extensively studied the IAD of LaF3.2 A major advantage of LaF3 in this work is its highly crystalline nature, even when deposited onto ambient temperature substrates. Our results with LaF3

Abstract:
Two fundamental concepts in welding consumable development were explored in this research. The first concept dealt with the introduction of yttrium-containing oxides into the weld metal for microstructural control and hydrogen trapping. The second concept suggested the use of fluoride species to displace hydrogen from the arc. Combining yttrium and fluorides into one single flux-cored consumable to capture the benefit of hydrogen reduction from both ingredients, however, proved to be difficult. The oxygen potential controlled by yttrium clashed with the fluorine potential controlled by KF. Sev

Abstract:
We will report on the composition, optical and mechanical properties of ion beam sputter deposited films of magnesium fluoride. Sputtered films were found to be more fluorine deficient and absorptive than thermally deposited films. Both of these film properties increased with increasing atomic weight of the sputter ion. Depositing films in the presence of a fluorine-containing gas (CF4) reinstated the fluorine and decreased the oxygen content of the film. Film composition and density were determined using Rutherford backscattering spectroscopy. The refractive index, stress, and microstructure

Abstract:
Des gisements d'uranium-thorium-éléments terrestres rares (U-Th-REE) encaissés dans des pegmatites granitiques, des skarns et des marbres sont présents dans toute la région de Bancroft, dans le centre de l'Ontario, au sein de la province de Grenville du Bouclier canadien. Ces gisements, exploités depuis la fin des années 1950, ont fait l'objet d'une étude dans le cadre du programme de géosciences de l'environnement de la CGC, afin de développer un modèle géoenvironnemental de gisement de minerai comprenant des caractéristiques minéralogiques et géochimiques détaillées.
