  1. 11. Synthesis and Energy Transfer Studies of a Donor-Host-Acceptor Triad

    Författare :Jerker Mårtensson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; orientation factor; self-assembly; porphyrin; cations; F #246; rster; dimer; donor-host-acceptor triad; energy transfer; degenerate transition; diaza-crown ether;

    Sammanfattning : This dissertation describes the synthesis of a donor-host-acceptor triad, D-H-A, and its self-assembly into a well-ordered dimer. The energy transfer (EnT) properties of D-H-A as it is, in the presence of a variety of guest molecules and in the dimeric form are presented. LÄS MER

  3. 12. Studying Morphology Formation and Charge Separation in Organic Solar Cells

    Författare :Yanfeng Liu; Fengling Zhang; Olle Inganäs; Jonas Bergqvist; Christoph J. Brabec; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : We are currently living in the era of automation and artificial intelligence, which requires more energy than ever before. Meanwhile, the reduction of carbon footprint is needed for keeping the environment sustainable. Exploring green energy is crucial. Solar power is one of the green energy sources. LÄS MER

  4. 13. Theoretical Study of the Electronic Factor in Electron Transfer Reactions

    Författare :Manuel Braga; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The electronic factor D is calculated for a number of organic and biological electron transfer systems. Quantum chemical methods at different levels of accuracy are used: ab initio Hartree-Fock, broken-symmetry, and correlation-corrected methods such as multiconfigurational second-order perturbation theory, and also the semiempirical CNDO/S method for very large systems.

  5. 14. Organic functionalization of graphene for applications in energy storage devices and optoelectronics

    Författare :Cheng Peng; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; graphene; aqueous energy storage; optoelectronics; organic functionalization; 2D materials;

    Sammanfattning : The emergence of one-atom layer thick materials, exemplified by graphene following its first exfoliation by Geim and Novoselov, has sparked significant research interest. Owing to their unique electronic structure, 2D materials are regarded as promising candidates for diverse applications, including field-effect transistors (FETs), solar energy harvesting, biological systems, water purification, and energy storage devices.

  7. 15. The MHC-glycopeptide-T cell interaction in collagen induced arthritis : a study using glycopeptides, isosteres and statistical molecular design in a mouse model for rheumatoid arthritis

    Författare :Lotta Holm; Jan Kihlberg; Morten Grötli; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Rheumatoid arthritis; collagen; T-cell; class II MHC; solid phase peptide synthesis; glycopeptide; peptide isostere; PCA; statistical molecular design; PLS; QSAR; sequence binding motif; Organic chemistry; Organisk kemi;

    Sammanfattning : Rheumatoid arthritis (RA) is an autoimmune disease affecting approximately 1% of the population in the western world. It is characterised by a tissue specific attack of cartilage in peripheral joints. Collagen induced arthritis (CIA) is one of the most commonly used animal models for (RA), with similar symptoms and histopathology. LÄS MER
