  1. 11. Grinding effects on surface integrity, flexural strength and contact damage resistance of coated hardmetals

    Författare :Jing Yang; Magnus Odén; Luis Llanes; Andrew Gant; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The tribological and mechanical behavior of coated tools depends not only on intrinsic properties of the deposited film but also on substrate surface and subsurface properties – such as topography and residual stress state – as well as on interface adhesion strength. It is particularly true in the case of coated tools based on WC-Co cemented carbides (backbone materials of the tool manufacturing industry, and simply referred to as hardmetals in practice) as substrates.

  3. 12. Ion Transport in Cross-linked Nanocellulose Membranes

    Författare :Hongli Yang; Isak Engquist; Magnus Berggren; Klaus-Dieter Kreuer; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Membranes; Nanocellulose; Cross-linking; Ion transport; Energy harvesting and storage devices;

    Sammanfattning : Ion-selective membranes, which allow ions with a certain charge and/or size to pass through while blocking other ions, have attracted much attention due to their diverse applications and outstanding roles in overcoming problems related to energy. In addition to the performance, the financial cost and renewability of materials are equally significant in the development of these membranes. LÄS MER

  4. 13. Ink-paper interaction : a study in ink-jet color reproduction

    Författare :Li Yang; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : An ink jet printing system consists of three fundamental parts: inks, printing engine, and substrates. Inks are materials creating color by selectively absorbing and scattering the visible illumination light. The printer acts as an ink distributor that governs the ink application. LÄS MER

  5. 14. Perinuclear Antineutrophil Cytoplasmic Antibodies in Inflammatory Bowel Disease

    Författare :Ping Yang; Stefan Lindgren; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Antineutrophil cytoplasmic antibodies (ANCAs) are a group of autoantibodies which are specific for granulocyte antigens. By indirect immunofluorescence (llF) on ethanol-fixed neutrophils, ANCAs can be divided into two types: a cytoplasmic staining pattern (C-ANCA) or a perinuclear staining pattern (P-ANCA). LÄS MER

  7. 15. Hemocompatibility of materials for use in prosthetic heart valves

    Författare :Yanqi Yang; Eric G. Butchart; Linköpings universitet; []
    Nyckelord :Heart valve prosthesis; mechanical heart valves; bioprosthetic heart valves; biomaterials; hemocompatibility; blood-material interaction; in vivo test; MEDICINE; MEDICIN;

    Sammanfattning : Thromboembolism (valve thrombosis and systemic embolism) is the main drawback of mechanical heart valve prostheses. The patients carrying these valves have to be subjected to life-long anticoagulant therapy to reduce thromboembolism. LÄS MER
