2. 1. Surface Complexation Studies in An (Th, U(IV), Pu(VI)) Systems

   Author : Mattias Olsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; surface complexation; sorption; adsorption; uranium; surface charge; FITEQL; plutonium;

   Abstract : Two-phase systems containing an electrolyte solution and a suspended solid were studied. The common denominator for the three systems examined in this work is that they contain actinides (elements of atomic numbers between 89 and 103) in either the solid phase or as a sorbate. Experiments were done on simple oxides. READ MORE

4. 2. Sorption and Surface Complexation of Plutonium

   Author : Mattias Olsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Plutonium is a constituent of spent nuclear fuel. As such, its behavior in contact with the surfaces of solids is of interest. This behavior will affect the migration of plutonium in case it is released into the environment. The chemistry of plutonium is rather complex. READ MORE

5. 3. Ab initio study of transition metal carbides and actinide compounds

   Author : Weiwei Sun; Pavel Korzhavyi; Igor Di Marco; Börje Johansson; Leon Petit; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computational material science; material physics; Materials Science and Engineering; Teknisk materialvetenskap;

   Abstract : Two classes of materials are investigated using ab intio methods based on density functional theory. The structural properties, electronic structure and thermodynamic properties of binary and ternary transition metal carbides are discussed in details. In addition, two actinide compounds will be presented. READ MORE
