    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thin films; Multicomponent alloys; Magnetron sputtering;

    Sammanfattning : In this Thesis, I have investigated multicomponent alloy based thin films synthesized by magnetron sputtering. The studies in the thesis are centered around the phase diagram of the CrFeCoNi nitrogen containing system. LÄS MER

  7. 20. Investigating volume change and ion transport in conjugated polymers

    Författare :Johannes Gladisch; Daniel Simon; Qibing Pei; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Volume changes are the foundation for a wide range of phenomena and applications, ranging from the movement of plants to valves and drug delivery devices. Therefore, it does not come as a surprise that controlled volume changes are an interesting topic of research. In this thesis, volume changes in polymers are the object of investigation. LÄS MER
