  2. 11. Synthesis of Organic Chromophores for Dye Sensitized Solar Cells

    Author : Daniel Hagberg; Licheng Sun; Elena Galoppini; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acceptor; chromophore; donor; dye sensitized solar cells; HOMO and LUMO energy level tuning; linker; organic dye.; Chemical engineering; Kemiteknik;

    Abstract :   This thesis deals with development and synthesis of organic chromophores for dye sensitized solar cells. The chromophores are divided into three components; donor, linker and acceptor. The development of efficient organic chromophores for dye sensitized solar cells starts off with one new organic chromophore, D5. READ MORE

  4. 12. Synthesis of Organic Chromophores for Dye Sensitized Solar Cells

    Author : Daniel Hagberg; Licheng Sun; Olof Ramström; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic Chromophores; Dye Sensitized Solar Cells; Organic chemistry; Organisk kemi;

    Abstract : This thesis is divided into four parts with organic chromophores for dye sensitized solar cells as the common feature and an introduction with general concepts of the dye sensitized solar cells. The first part of the thesis describes the development of an efficient organic chromophore for dye sensitized solar cells. READ MORE

  5. 13. Controlled Degradation of Polyester-Ethers Revealed by Mass Spectrometry Techniques

    Author : Anders Höglund; Ann-Christine Albertsson; Jukka Seppälä; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Degradation products; biocompatibility; -caprolactone; 1; 5-dioxepan-2-one; 6-hydroxyhexanoic acid; 3- 2-hydroxyethoxy propanoic acid; oligomers; Polymer chemistry; Polymerkemi;

    Abstract : The use of degradable biomedical materials in e.g. tissue engineering and controlled drug delivery has changed medical science during recent decades. The key question is to adapt the material with respect to mechanical properties, surface characteristics, and degradation profile to suit its intended application. READ MORE

  6. 14. Support for sustainable welfare? : A study of public attitudes related to an eco-social agenda among Swedish residents

    Author : Kajsa Emilsson; Socialpolitik och hållbarhet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Hållbar välfärd; Attityder; Politisk handling; Ekosociala policyer; Ekosocial agenda; Sustainable welfare; Public attitudes; Political action; Social-ecological transformations; Eco-social policy;

    Abstract : This thesis explores Swedish residents’ attitudes related to an eco-social agenda from a sustainable welfare perspective. It investigates public support for general policy goals related to an eco-social agenda as well as for specific eco-social policies. READ MORE

  7. 15. Synchrotron radiation study of free and adsorbed organic molecules

    Author : Teng Zhang; Carla Puglia; Nils Mårtensson; Svante Svensson; Mats Götelid; Uppsala universitet; []
