  1. 31. Cellular toxicity of quinones : Redox- and addition chemistry

    Författare :Karin Öllinger; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Quinoid compounds are widely occurring in nature. They have cytotoxic properties and they are also used as antineoplastic agents. The cytotoxic properties can be explained by the ability of quinones to generate active oxygen species by redox cycling, by addition to cellular nucleophiles, and by inhibition of DNA transcription.

  3. 32. Excited State Aromaticity and Antiaromaticity : Fundamental Studies and Applications

    Författare :Rabia Ayub; Henrik Ottosson; Manabu Abe; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Baird s rule; Clar s rule; Computational quantum chemistry; Excited state aromaticity; Excited state aromaticity indicators; Organic photochemistry; Polycyclic conjugated hydrocarbons; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Sammanfattning : The central theme of this thesis is the ability to tune various molecular properties by controlling and utilizing aromaticity and antiaromaticity in the lowest electronically excited states. This investigation is based on qualitative theory, quantum chemical (QC) calculations and experimental work. LÄS MER

  4. 33. Theoretical studies of response properties of organic molecules

    Författare :Anders Bernhardsson; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; kvantkemi; Teoretisk kemi; Theoretical chemistry; quantum chemistry;

    Sammanfattning : In this thesis eight papers are presented. They represent development of theory and implementation technique in quantum chemistry, as well applications. The first two papers describe advances in geometry optimization techniques. LÄS MER

  5. 34. Development of permporometry for analysis of MFI membranes

    Författare :Danil Korelskiy; Olov Öhrman; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Sammanfattning : Zeolite membranes exhibiting high flux and high selectivity are of major interest for potential future applications. In order to achieve high flux and high selectivity, the zeolite film must be thin (< 1 µm) and free from flow-through defects. LÄS MER

  7. 35. Externally fired gas turbine cycle based on biomass gasification gas as fuel

    Författare :Fabiola Baina Veizaga; Torsten Fransson; Lasse Rosendhal; KTH; []
    Nyckelord :Externally fired micro gas turbine; heat transfer; combustion of biomass derived gas; micro combined heat and power; Energiteknik; Energy Technology;

    Sammanfattning : Energy services are essential for the development of societies, reduce poverty, and improve the living standards of inhabitants. The conventional routes to provide energy services employ fossil fuels. However, this involves environmental and availability concerns. LÄS MER
