  3. 2. Phase Formation of Nanolaminated Transition Metal Carbide Thin Films

    Författare :Chung-Chuan Lai; Johanna Rosén; Per Eklund; Lars Hultman; Miladin Radovic; Linköpings universitet; []

    Sammanfattning : Research on inherently nanolaminated transition metal carbides is inspired by their unique properties combining metals and ceramics, such as higher damage tolerance, better machinability and lower brittleness compared to the binary counterparts, yet retaining the metallic conductivity. The interesting properties are related to their laminated structure, composed of transition-metalcarbide layers interleaved by non-transition-metal (carbide) layers. LÄS MER

  4. 3. Design and Development of Mineral Structure Specific Collectors in Flotation

    Författare :Tommy Karlkvist; Beena Rai; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : The success of mineral flotation processes depends on the hydrophobization of the surface for the desired mineral particles whilst keeping, or making, all other minerals hydrophilic. This is achieved by adding several reagents to the flotation pulp to adsorb selectively at the mineral/water interface. LÄS MER
