  1. 16. EPR Studies of Ruthenium-Manganese Complexes as Biomimetic Models for Photosystem II - Approaching Artificial Photosynthesis

    Author : Ping Huang; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; WOC; bridging-mode modification; water oxidation; EPR; Ru-Mn complexes; PSII; Artificial Photosynthesis; D donor -S sensitizer -A acceptor molecular module; High Mn valence states.; Biochemistry; Metabolism; Biokemi; metabolism;

    Abstract : In natural photosynthesis, solar energy is converted to chemical energy by photosynthetic reaction centers. In green plants and algae, Photosystem II (PSII) and Photosystem I (PSI) absorb light and utilize the charge separation reactions to convert solar energy to chemical energy. READ MORE

  2. 17. Fiber Optic Sensors for Monitoring of Lithium- and Sodium-ion Batteries

    Author : Jonas Hedman; Fredrik Björefors; Daniel Brandell; Alexis Grimaud; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Evanescent waves; Fiber optic evanescent wave sensors; Fiber optic sensors; Graphite; Hard carbon; LiBOB; Lithium iron phosphate; Lithium manganese oxide; Lithium plating; Lithium-ion batteries; Prussian white; Sodium plating; Sodium-ion batteries; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : Rechargeable batteries, particularly lithium-ion batteries, have rapidly evolved since their introduction and now dominate the market, owing primarily to their high energy and power densities. With growing demand for high-performance batteries in portable electronics and electric vehicles, the need for safe, efficient, and reliable batteries is crucial. READ MORE

  3. 18. Cationic Interactions with Nucleic Acids With Focus on Anticancer Active Platinum(II) Complexes

    Author : Åse Sykfont Snygg; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; in-line cleavage; Cisplatin; oxaliplatin; circular dichroism; DENSPM; polyamines; siRNA; pseudoknot; RNA; thermal melting; anticancer active Pt II complex; DNA;

    Abstract : It is well documented that the antitumour activity of the Pt(II)-complex cisplatin, and similar anticancer active complexes, is a result of metalation of DNA, and thereby inhibition of cell proliferation. Since nucleic acids are polyanions at physiological pH, the rate of adduct formation with positively charged complex, as the hydrolyzed Pt(II) complexes studied in this work, is influenced by the ionic environment surrounding the polymer.

  4. 19. Development of metal complexes for water oxidation

    Author : Bao-Lin Lee; Sascha Tiede; Stockholms universitet; []
    Keywords : ;

    Abstract : In the course of developing a water oxidation catalyst, five metal complexes have been synthesised, characterised and studied for catalytic activity. Three of them are dinuclear complexes (Ru, Co and Cu) of 2,6-bis[(2-hydroxybenzyl)-(2-pyridylmethyl)aminomethyl]-4-methylphenol (H3bbpmp). READ MORE

  5. 20. Electron Donor Systems in Natural and Artificial Photosynthesis

    Author : Ann Magnuson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; solar energy; artificial photosynthesis; Photosystem II; EPR; Biology; Biologi;

    Abstract : Photosynthesis is the process by which light energy is converted into chemical products, in photoautotrophic bacteria, algae and plants. The principal idea is the production of reducing agents by photo-induced oxidation of a sacrificial electron donor. READ MORE
