    Sammanfattning : This thesis describes how radical cyclization chemistry can be applied for the construction of heterocyclic compounds.In the first part, a series of electron deficient α-phenylselenenylalkenes were prepared via a PhSeCl-addition/HCl-elimination sequence. LÄS MER

  3. 2. The role of biobased building materials in the climate impacts of construction : Effects of increased use of biobased materials in the Swedish building sector

    Författare :Diego Peñaloza; Magnus Wålinder; Martin Erlandsson; Andreas Falk; Johanna Berlin; Dimitris Athanassiadis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LCA; timber buildings; timber bridges; biobased building materials; dynamic LCA; climate change mitigation; building stock; scenario analysis; biogenic carbon; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : A significant share of the global climate change impacts can be attributed to the construction sector. One mitigation strategy is increasing the use of biobased materials. Life cycle assessment (LCA) has been used to demonstrate the benefits of this, but forest complexities create uncertainty due to omission of key aspects. LÄS MER

  4. 3. Designing Platform Emulation

    Författare :Daniel Rudmark; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; open platforms; platform emulation; outlaw innovation; action design research; guided emergence; open platforms;

    Sammanfattning : Many contemporary firms and public agencies seek to engage external third-party developers to supply complementary applications. However, this type of development sometimes occurs without organizational consent, which creates problems for subjected organizations at both the technical and organizational levels. LÄS MER

  5. 4. Microfluidic biosensing systems based on enzymes, antibodies and cells

    Författare :Richard Davidsson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Analytisk kemi; chemiluminescence; immobilization; cell; antibody; enzyme; miniaturization; Microfluidic; microchip;

    Sammanfattning : The rapid developments within the life science and biotechnology areas put up ever-new demands on more sophisticated techniques and methods for chemical and biological analysis to reach deeper insight into the events at molecular level. Miniaturisation of assays and systems on microchips is one way to increase throughput and advance through parallel analysis lines, multiplexing and integration. LÄS MER
