  1. 11. High Performance Aluminium Alloys for Laser Powder Bed Fusion: Alloy Design and Development

    Författare :Bharat Mehta; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive Manufacturing; Precipitation Kinetics; Integrated Computational Materials Engineering; Laser Based Powder Bed Fusion; Heat Treatment; Aluminium Alloys;

    Sammanfattning : Additive Manufacturing (AM), particularly Laser Based Powder Bed Fusion (LB-PBF) has proven to be a notable technology to produce novel microstructures and expand the ceiling of product design. However, the development of novel alloys in metal LB-PBF has not followed the same pace as development of product design. LÄS MER

  3. 12. Radiation crosslinking of cellulose fibers to obtain rigid lightweight paperboard

    Författare :Mikaela Börjesson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Paper; Modification; Ester; Crosslinking; Cellulose; UV radiation; Acrylates; Packaging;

    Sammanfattning : Cellulosic materials are used in a wide range of areas of application, and one of these is paperboard for packaging solutions. Paper or paperboard as a packaging material has benefits like low density, low costs, high stiffness, good printability, and paper is environmentally friendly. LÄS MER

  4. 13. Film morphology for organic solar cells : Effect of Solubility and Gravity Conditions

    Författare :Ishita Jalan; Jan van Stam; Leif Ericsson; Stela Andrea Muntean; Philippe Leclère; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; Chemistry - Physical Chemistry; Kemi - fysikalisk kemi;

    Sammanfattning : Organic photovoltaics is a promising environmentally friendly technology, due to their printability, light-weight nature and mechanical flexibility, and the possibility to use off-grid. Research and development in this field has resulted in power conversion efficiencies of over 15%. LÄS MER

  5. 14. Faba bean foods: Structure and texture : Evaluation of faba bean component behaviours in different product matrices

    Författare :Klara Nilsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Faba bean (Vicia faba minor) is a cool-climate crop that could serve as a locally sourced sustainable ingredient in transition towards a more plant-based diet in temperate regions. Poor texture is one of the main aversion factors of plant-based foods, so this thesis characterised the functionality of faba bean components and their effect on structure and texture in different food matrices.

  7. 15. Polymer-coated paper and board - Role of substrate, polymer characteristics and additives

    Författare :Thomas Schuman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface energy; latex; surface roughness; corona; contact angle; barrier properties; liquid sorption; surface treatment; calendering; poly vinyl alcohol ; coating;

    Sammanfattning : The surface roughness of paper or board has a significant influence on the homogeneity of an applied polymer film, and this thesis discusses how it may be improved by a surface treatment, e.g. high-temperature calendering or precoating. LÄS MER
