  1. 21. Efficient Carbohydrate Synthesis By Intra- and Supramolecular Control

    Författare :Hai Dong; Olof Ramström; Ulf Nilsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbohydrate Chemistry; Supramolecular Control; Ambident Reactivity; Bioorganic chemistry; Bioorganisk kemi;

    Sammanfattning : The Lattrell-Dax method of nitrite-mediated substitution of carbohydrate triflates is an efficient method to generate structures of inverse configuration. In this study, the effects of the neighboring group on the Lattrell-Dax inversion were explored. LÄS MER

  3. 22. Synthesis and characterization of zeolite films and membranes

    Författare :Magdalena Gualtieri; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Sammanfattning : In this work, a seeding technique was used to synthesize films and membranes of FAU, LTA and MFI type zeolites. In the first part, hydrothermal growth was performed without organic template molecules, which resulted in template-free zeolite films and membranes. LÄS MER

  4. 23. Synthesis and characterisation of thermoset-layered silicate nanocomposites

    Författare :Xavier Kornmann; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : Thermoset-layered silicate nanocomposites are materials reinforced on a molecular scale by 1 nm-thick silicate layers of high aspect ratio dispersed in a thermoset matrix. These new materials were synthesised from unsaturated polyester and several epoxy resins (DGEBA/diamines and TGDDM/DDS) using two different approaches. LÄS MER

  5. 24. Dual Careers of Swedish University Student-Athletes : A Synthesis of Holistic Developmental and Ecological Approaches

    Författare :Lukas Linnér; Natalia Stambulova; Kristina Ziegert; Judy Van Raalte; Högskolan i Halmstad; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; dual career; student-athlete; university; holistic developmental approach; holistic ecological approach; and dual career assistance; dubbel karriär; elitidrottande student; universitet; holistiskt utvecklingsperspektiv; holistiskt ekologiskt perspektiv; och stödmodell;

    Sammanfattning : The Swedish dual career (DC) system has a history of providing support at the gymnasium/upper secondary level since the early 1970s. Since 2012, there has been a call from the European Union to member states to develop a support provision throughout athletes’ DCs based on national research. LÄS MER

  7. 25. Synthesis, characterization and properties of zeolite films and membranes

    Författare :Magdalena Lassinantti; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Sammanfattning : The work presented in this thesis was aimed to synthesize zeolite films in the absence of organic additives to avoid the potentially detrimental calcination procedure. Furthermore, the support surface was seeded with colloidal seed crystals prior to film growth. This technique has previously been used to prepare thin zeolite films. LÄS MER
