  1. 1. Optimizing Ice-Resistant Surfaces: Unifying Self-Healing, Durability, and Functional Design for Superior Anti-/de-icing Performance

    Författare :Jun Chen; Yijun Shi; Pär Marklund; Marcus Björling; Jianying He; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anti- de-icing; Machine Elements; Maskinelement;

    Sammanfattning : Snow and ice accumulation on critical infrastructure such as wind power turbines and power lines cause significant challenges and safety hazards in cold climate regions during wintertime. Research into anti-/de-icing technologies has been divided into two main streams, i.e., active, and passive approaches. LÄS MER

  3. 2. Active friction control by using CO2 and moisture

    Författare :Jing Hua; Shi Yijun; Shah Faiz; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; friction control; Machine Elements; Maskinelement;

    Sammanfattning : Nowadays the demand for intelligent control of tribological interactions is strongly increasing in various applications. We often strive to minimize friction but there are also many situations where high friction is desirable. In some cases, something in between, i.e. LÄS MER

  4. 3. Friction control in different lubrication regimes

    Författare :Jing Hua; Yijun Shi; Kalin Mitjan; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; friciton control; glycerol; lubrication regime; Machine Elements; Maskinelement;

    Sammanfattning : We often strive to minimize friction but there are also many situations where high friction is desirable. In some cases, something in between, i.e. optimum friction, is attractive. LÄS MER

  5. 4. Tribology of carbon fiber reinforced PTFE composites in dry gas environments

    Författare :Pontus Johansson; Pär Marklund; Marcus Björling; Yijun Shi; Stephen Kukureka; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

    Sammanfattning : With hydrogen being one of the key pillars of decarbonization, the reliability and efficiency of hydrogen applications become increasingly important. In applications such as oil-free reciprocating hydrogen compressors and Stirling engines, the self-lubricating pistonrings and other dynamic seals are critical components in terms of efficiency, service life and proper functioning.
