ANEHEIM Department of Chemical and Biological Engineering Chalmers University of Technology Abstract When uranium is used as fuel in nuclear reactors it both undergoes neutron induced fission as well as neutron capture. Through successive neutron capture and beta decay transuranic elements such as neptunium, plutonium, americium and curium are produced in substantial amounts. These radioactive elements are mostly long-lived and contribute to a large portion of the long term radiotoxicity of the used nuclear fuel. This radiotoxicity is what makes it necessary to isolate the used fuel for more than 100,000 years in a final repository in order to avoid harm to the biosphere. -

Ge–Sb–S–Se–Te Amorphous Chalcogenide Thin Films Towards On

Bernard1, C. Sabbione1, M. Tessaire1, J.-M. Fédéli1, A. Coillet 3, B. Cluzel3 & P. Noé 1* Thanks to their unique optical properties Ge–Sb–S–Se–Te amorphous chalcogenide materials and compounds ofer tremendous opportunities of applications, in particular in near and mid-infrared range. This spectral range is for instance of high interest for photonics or optical sensors. Using co-sputtering technique of chalcogenide compound targets in a 200 mm industrial deposition tool, we show how by modifying the amorphous structure of GeSbwSxSeyTez chalcogenide thin flms one can signifcantly tailor their linear and nonlinear optical properties. Modelling of spectroscopic ellipsometry data collected on the as-deposited chalcogenide thin flms is used to evaluate their linear and nonlinear properties. Moreover, Raman and Fourier-transform infrared spectroscopies permitted to get a description of their amorphous structure. For the purpose of applications, their thermal stability upon annealing is also evaluated. We demonstrate that depending on the GeSbwSxSeyTez flm composition a trade-of between a high transparency in near- or mid-infrared ranges, strong nonlinearity and good thermal stability can be found in order to use such materials for applications compatible with the standard CMOS integration processes of microelectronics and photonics. Chalcogenides are commonly defned as non-oxide compounds containing at least one chalcogen element such as S, Se and/or Te (belonging to group 16 of O) alloyed with electropositive elements (more ofen elements of group 15 (As, Sb, Bi) and/or group 14 (Si, Ge, Sn, Pb)). -
Electrodeposition of Alloys Or Compounds in Molten Salts and Applications

Hamel Laboratoire de Génie Chimique, Département Procédés Electrochimiques et Matériaux, CNRS UMR 5503, Université Paul-Sabatier, 118 route de Narbonne, 31062 Toulouse Cedex 04, France (Received 12 February 2003; accepted 18 April 2003) Abstract This article deals with the different modes of preparation of alloys or intermetallic compounds using the electrodeposition in molten salts, more particularly molten alkali fluorides. The interest in this process is to obtain new materials for high technology, particularly the compounds of reactive components such as actinides, rare earth and refractory metals. Two ways of preparation are considered: (i) electrocoating of the more reactive metal on a cathode made of the noble one and reaction between the two metals in contact, and (ii) electrocoating on an inert cathode of the intermetallic compound by coreduction of the ions of each elements. The kinetic is controlled by the reaction at the electrolyte interface. A wide bibliographic survey on the preparation of various compounds (intermetallic compounds, borides, carbides…) is given and a special attention is paid to the own experience of the authors in the preparation of these compounds and interpreta- tion of their results.
