  1. 1. Molecular Recognition Mechanisms: Thermodynamics and Polarization Spectroscopy of DNA--Intercalator Complexes

    Författare :Hans-Christian Becker; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; groove-binding; DNA; intercalation; linear dichroism; polarization spectroscopy; thermodynamics; enthalpy--entropy compensation;

    Sammanfattning : Mechanisms for molecular recognition in DNA--intercalator complexes have been investigated by optical spectroscopy. The effect of electrical charge on binding geometry and binding thermodynamics was studied using 2,7-diazapyrene (DAP) and its N-methylated cations DAP+ and DAP2+ as model ligands. LÄS MER

  3. 2. Tuning of the Excited State Properties of Ruthenium(II)-Polypyridyl Complexes

    Författare :Maria Abrahamsson; Leif Hammarström; Hans-Christian Becker; Russell Schmehl; Uppsala universitet; []
    Nyckelord :Physical chemistry; Artificial photosynthesis; Ruthenium II ; Bistridentate complexes; Excited state lifetime; Linear donor-photosenstizer-acceptor arrays; Temperature dependence; Excited state decay; Fysikalisk kemi;

    Sammanfattning : Processes where a molecule absorbs visible light and then converts the solar energy into chemical energy are important in many biological systems, such as photosynthesis and also in many technical applications e.g. photovoltaics. LÄS MER

  4. 3. Context reasoning, context prediction and proactive adaptation in pervasive computing systems

    Författare :Andrey Boytsov; Christian Becker; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Distribuerade datorsystem; Mobile and Pervasive Computing;

    Sammanfattning : The paradigm of pervasive computing aims to integrate the computing technologies in a graceful and transparent manner, and make computing solutions available anywhere and at any time. Different aspects of pervasive computing, like smart homes, smart offices, social networks, micromarketing applications, PDAs, etc. LÄS MER

  5. 4. Situation awareness in pervasive computing systems : reasoning, verification, prediction

    Författare :Andrey Boytsov; Christian Becker; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; situation awareness; context awareness; pervasive computing; ubiquitous computing; context prediction; Pervasive Mobile Computing; Distribuerade datorsystem;

    Sammanfattning : The paradigm of pervasive computing aims to integrate the computing technologies in a graceful and transparent manner, and make computing solutions available anywhere and at any time. Different aspects of pervasive computing, like smart homes, smart offices, social networks, micromarketing applications, PDAs are becoming a part of everyday life. LÄS MER

  7. 5. Cyclic peptides as biological tools : Applications for diagnosis and therapeutics in rheumatoid arthritis and COVID-19

    Författare :Camilla Eriksson; Ulf Göransson; Sunithi Gunasekera; Christian Becker; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Scaffold peptides; peptide grafting; rheumatoid arthritis; SARS-CoV-2; autoantibodies; peptide synthesis; pharmacognosy;

    Sammanfattning : The overall aims of the projects included in this thesis were to design, synthesize and evaluate cyclic peptide scaffolds grafted with biological epitopes for their ability to bind antibodies in rheumatoid arthritis and COVID-19 sera. One of the main outcomes of this thesis was the observation that scaffold peptides grafted with target epitopes efficiently neutralized anti-citrullinated protein autoantibodies (ACPA) from rheumatoid arthritis patients.
