  1. 1. Enhancing UV-protection of clear coated wood by utilizing reactive UV-absorber and epoxyfunctionalized soybean oil

    Författare :Sara Olsson; Mats KG Johansson; Emma Östmark; Mats Westin; Philip Evans; Minna Hakkarainen; Peter Weissenborn; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; UV-protaction; wood; clear coating; UV absorber; epoxy functionalized soybean oil; grafting;

    Sammanfattning : This work presents the development of a new pretreatment for clear coated wood, that aims to increase the photoprotection of exterior wood products, and at the same time make the system more environmentally friendly. The pretreatment comprises the reactive UV absorber 2-hydroxy-4(2,3-epoxy­propoxy)-benzophenone (HEPBP), which has a primary epoxy group that can be covalently attached to the hydroxyl groups of the wood substrate.

  3. 2. High-Performance Composites from Modified Wood Fiber

    Författare :Mats Westin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kraft lignin; fiberboard; lignocellulosic fiber; durability; wood fiber; mechanical properties; dimensional stability; decay resistance; acetylation; composite;

    Sammanfattning : The objective of this work was to produce and evaluate high-performance wood fiber composites. High-performance was defined as: high dimensional stability and a high durability, including resistance to wood-decaying organisms (fungi, bacteria, and insects). LÄS MER

  4. 3. Inclusive Digital Socialisation : Designs of Education and Computer Games in a Global Context

    Författare :Thomas Westin; Mats Danielson; Dimitris Grammenos; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; computer games; education; socialisation; inclusion; exclusion; development; accessibility; Computer and Systems Sciences; data- och systemvetenskap;

    Sammanfattning : Digital socialisation is to learn the ways of living online, across national borders, local cultures and societies and has to be inclusive for equal participation. Conditions for this socialisation process are different due to both local and individual limitations. LÄS MER

  5. 4. Blatte betyder kompis : Om maskulinitet och språk i en högstadieskola

    Författare :Rickard Jonsson; Charles Westin; Don Kulick; Mats Börjesson; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Masculinity; sexuality; ethnicity; language; performativity; normative Swedishness; heteronormativity; Education; Pedagogik; pedagogik; Education;

    Sammanfattning : This thesis deals with masculinity and language among a group of teenage boys. Based on a year’s fieldwork at a middle school in a Stockholm suburb, the study focuses on how language is used to “perform” masculinity and how the stereotype of the “immigrant youth” emerges in daily communication in school.

  7. 5. Dissolution of cellulose for textile fibre applications

    Författare :Martin Kihlman; Ulf Germgård; Mats Westin; Lars Stigsson; Stefan Backa; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alkaline aqueous solvent systems; cellulose; dissolution; dissolving pulp; kraft pulp; pretreatment; pulp characterization; sulfite pulp; textile fibres; Chemical Engineering; Kemiteknik;

    Sammanfattning : This thesis forms part of a project with the objective of developing and implementing a novel, wood-based, process for the industrial production of cellulose textile fibres. This new process should not only be cost effective but also have far less environmental impact then current processes. LÄS MER
