  2. 1. Material migration in tokamaks : Erosion-deposition patterns and transport processes

    Author : Armin Weckmann; Marek Rubel; Rudolf Neu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEXTOR; fusion; plasma physics; transport; migration; tracers; tokamak; limiter; divertor; high-Z; ion beam analysis; Rutherford backscattering; Nuclear reaction analysis; Elastic recoil detection analysis; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Controlled thermonuclear fusion may become an attractive future electrical power source. The most promising of all fusion machine concepts is called a tokamak. The fuel, a plasma made of deuterium and tritium, must be confined to enable the fusion process. It is also necessary to protect the wall of tokamaks from erosion by the hot plasma. READ MORE

  4. 2. A Study on the Reaction between MgO Based Refractories and Slag-Towards the Development of Carbon-free Lining Material

    Author : Huijun Wang; Sichen Du; Stuart Millman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MgO refractory; lining material; carbon-free; clean steel; ladle glaze; slag penetration; dissolution mechanism; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : In present thesis, the fundamental studies on the reaction between MgO based refractories and slag were undertaken for the development of a carbon-free bonding MgO lining material. Alumina was selected as a potential binder material. Due to MgO-Al2O3 chemical reaction, the developed refractory was bonded by MgO·Al2O3 spinel phase. READ MORE

    Abstract : The three main components of wood, namely, cellulose, hemicellulose, and lignin, can be used in various areas. However, since lignin covalently crosslinks with wood polysaccharides creating networks that is an obstacle for extraction, direct extraction of different wood components in high yield is not an easy matter.
