  1. 16. Natural products from nonracemie building blocks : synthesis of pine sawfly pheromones

    Author : Michael Larsson; Torbjörn Norin; Gunnar Westman; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Total synthesis; diastereoselective addition; dimethylzinc; Lewis acid; alkyllithium; Organisk kemi; Organic chemistry; Organisk kemi;

    Abstract : This thesis describes a number of synthetic approaches for obtaining chiral, enantiomerically pure natural products, in particular some semiochemicals. This has been accomplished by using various strategies; by starting from compounds from the chiral pool, by using chiral auxiliaries, via enzymatic resolutions or by chemical asymmetric synthesis.

  2. 17. Supporting the design phase of industrialised house building using a product platform approach : A case study of a timber based post and beam building system

    Author : Shamnath Thajudeen; Fredrik Elgh; Martin Lennartsson; Marcus Sandberg; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrialised house building; Product platform; Design support; Building system; Post and beam; Glulam; Industriellt husbyggande; Produktplattformar; Designstöd; Byggsystem; Pelar-balksystem; Limträ;

    Abstract : In recent years, industrialised house building has gained shares on the Swedish house building market. The market demands for industrialised house building are exceeding the available supply of housing and experiencing a substantial increase in the housing production costs. READ MORE

  3. 18. Building Sustainable Batteries : Organic electrodes based on Li- and Na-benzenediacrylate

    Author : Alina Oltean; Daniel Brandell; Leif Nyholm; Steven Renault; Martin Sjödin; Robert Dominko; Uppsala universitet; []
    Keywords : Organic Electrode Materials; Li-ion Batteries; Na-ion Batteries; Calendaring; Recycling Process; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : As possible alternatives to the conventional inorganic Li- or Na-ion battery electrode materials, organic compounds have recently drawn considerable attention. However, major challenges such as poor electronic conductivity, solubility in battery electrolyte or fast capacity decay of the resulting electrochemical cells are some of the reasons that hold these compounds back from becoming commercial solutions in the energy system.

  4. 19. Life Cycle Assessment of Building Products. Case Studies and Methodology

    Author : Åsa Jönsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VOCs; environmental assessment; floorings; methods; LCA; concrete; indoor climate; Life Cycle Assessment; structural frames; building materials; steel; tools;

    Abstract : The main objectives of this thesis were to demonstrate how Life Cycle Assessment (LCA) may be applied to building products, to describe what methodological LCA issues are specific to building products, to work out solutions to some of these issues and to relate LCA to other environmental assessment methods that may be applied to building products. First, in a literature study, the state of the art in the field of environmental assessment of building products is described, and the five articles constituting the thesis are put into context.

  5. 20. Chemical emissions from building structures : emission sources and their impact on indoor air

    Author : Annika Glader; Ingrid Liljelind; Berndt Stenberg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; indoor air quality; VOC; building structures; emissions; health effects; moisture damage; PCA; OPLS; inomhusluft; VOC; konstruktioner; emissioner; hälsoeffekter; byggnadsmaterial; fuktskada; PCA; OPLS; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Abstract : Chemical compounds in indoor air can adversely affect our comfort and health. However, in most cases there is only a limited amount of information available that can be used to assess their health risk. Instead the precautionary principle is often applied, i.e. READ MORE
