  2. 6. Preparation and characterisation of refractory whiskers and selected alumina composites

    Author : Mats Carlsson; Mats Johnsson; Tor Grande; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; VLS-growth; Characterisation; Whiskers; Sintering; Ceramic composites; Inorganic chemistry; Oorganisk kemi;

    Abstract : A whisker is a common name of single crystalline inorganic fibre of small dimensions, typically 0.5-1 μm in diameter and 20-50 μm in length. Whiskers are mainly used as reinforcement of ceramics. This work describes the synthesis and characterisation of new whisker types. READ MORE

  4. 7. Magnetron sputtering of binary, ternary and multicomponent thin film borides and carbides

    Author : Paulius Malinovskis; Ulf Jansson; Erik Lewin; Vladimir Vishnyakov; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Design of new thin film materials with improved properties and functionality is an important research field in materials science. In this thesis, I have used magnetron sputtering to deposit new thin film materials, which should combine high hardness and high ductility with other properties such as low friction or a good corrosion resistance.

  5. 8. Fundamental aspects of HiPIMS under industrial conditions

    Author : Mattias Samuelsson; Ulf Helmersson; Torbjörn Joelsson; Hans Högberg; Bengt Wälivaara; Jörg Patscheider; Linköpings universitet; []
    Keywords : ;

    Abstract : Fundamental aspects of the high power impulse magnetron sputtering (HiPIMS) process and its implication for film growth under industrial conditions have been studied. The emerging HiPIMS technique exhibits a higher plasma density and an enhanced degree of ionisation of sputtered material as compared to conventional direct current magnetron sputtering (DCMS).

  6. 9. Computational prediction of novel MAB phases

    Author : Adam Carlsson; Johanna Rosén; Denis Music; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The synthesis procedure of any materials system is often considered a challenging task if performed without any prior knowledge. Theoretical models may thus be used as an external input and guide experimental efforts toward novel exotic materials which are most likely to be synthesizable. READ MORE

  7. 10. Venturing Further into the Field of 2D Materials and their Laminated Parent Phases

    Author : Pernilla Helmer; Johanna Rosén; Jonas Björk; Martin Dahlqvist; Hannu-Pekka Komsa; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Density Functional Theory; Bonding analysis; Themodynamical stability; Electronic band structure; Computational screening; Dynamical stability; Nanolaminate; MXene; 2D material; Boridene; Chemical exfoliation; Selective etching;

    Abstract : The field of 2D materials is a relatively young and rapidly growing area within materials science, which is concerned with atomically thin states of matter. Because of their intrinsic 2D morphology, 2D materials have exceptionally high surface to weight or surface to volume ratio. READ MORE
