2. 16. Helium Filled Bubbles in Solids : Nucleation, Growth and Swelling

   Author : Odd Runevall; Nils Sandberg; Charlotte Becquart; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Helium; Radiation Damage; DFT; molybdenum; MgO;

   Abstract : When nuclear fuel, fabricated for the purpose of transmuting spent fuel is irradiated, significant amounts of He is produced from alpha particles mainly emitted when 242Cm decays into 238Pu. From irradiation experiments it is known that the presence of He in the solids alters the swelling behaviour of the material. READ MORE

   Abstract : Atomic data are needed in many different areas of science and technology. Examples of users are the astronomical community and the lighting industry. In this work, the purpose of the projects has been to produce reliable atomic data needed to solve specific astrophysical problems. READ MORE

5. 18. Passivation of Austenitic Stainless Steel

   Author : Lena Wegrelius; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; chloride; molybdenum; passivation; hydrochloric acid; nitrogen; ESCA; dissolution;

   Abstract : The objective of this thesis is to study the corrosion resistance and passivation of high alloyed austenitic stainless steels exposed to hydrochloric acid. The introductory section gives a background to the subject; electrochemical measurements and surface analysis by the ESCA-technique (Electron Spectroscopy for Chemical Analysis). READ MORE

6. 19. Liquid Exfoliation of Molybdenum Disulfide for Inkjet Printing

   Author : Viviane Forsberg; Håkan Olin; Renyun Zhang; Magnus Hummelgård; Joakim Bäckström; Li Yang; Mittuniversitetet; []
