  2. 16. First principles study of tungsten-based alloys: From defect thermodynamics to phase diagrams

    Author : Leili Gharaee; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; structural materials; first-principles calculations.; point defects; tungsten alloys; irradiation;

    Abstract : Nuclear fusion is a very attractive option for energy production as it is clean, safe and efficient. The major obstacle in construction of fusion power plants is the development of materials that can tolerate the extreme operational condition especially high-energy neutron flux. READ MORE

  6. 19. Effects of Irradiation and Thermal Ageing on the Nanoscale Chemistry of Steel Welds

    Author : Kristina Lindgren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spinodal decomposition; thermal ageing; low alloy steel; reactor pressure vessel; irradiation damage; atom probe tomography; core barrel; clustering;

    Abstract : Structural materials of nuclear power plants degrade during operation due to thermal ageing and irradiation from the reactor core. Effects on the materials are an increase in hardness and tensile strength, and a decrease in ductility and fracture toughness, i. e. embrittlement. READ MORE

  7. 20. Single-Proton Irradiation of Living Cells - Development of New Tools for Low-Dose Radiation Research

    Author : Natalia Arteaga; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lithography; UVL; EBL; SeACell; human hepatoma cells HepG2 ; reactive oxygen species ROS ; bystander effect; SU-8; cell recognition; cell irradiation; Single-Ion Hit Facility; low-dose; Fysicumarkivet A:2010:Arteaga Marrero;

    Abstract : A Single-Ion Hit Facility (SIHF) consists of a custom-build facility based in particle accelerators which offers irradiation controlling the number of delivered particles with a precise targeting localization. The irradiation spot can be confined down to the nanometre scale allowing the irradiation of subcellular compartments with a single particle. READ MORE
