  1. 1. 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

  3. 2. State Estimation of Lithium-ion Batteries

    Författare :Xiaolei Bian; Longcheng Liu; Jinying Yan; Huazhen Fang; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-ion battery; State of charge; State of health; Model-based method; Extended Kalman filter; Filter tuning; Fusion model; Chemical Engineering; Kemiteknik;

    Sammanfattning : To guarantee the safety operation, the key states of lithium-ion battery, e.g., the state of charge and the state of health, must be estimated and monitored accurately. This thesis is mainly to develop models and algorithms to accurately and robustly estimate the key battery states, based on the available measurements i. LÄS MER

  4. 3. Anabolic Androgenic Steroids and the Brain : Studies of Neurochemical and Behavioural Changes Using an Animal Model

    Författare :Pia Steensland; Christina Gianoulakis; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Anabolic Androgenic Steroids AAS ; aggression; alcohol intake; defensive behaviours; dependence; opioid peptides; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; biologisk beroendeforskning; Biological Research on Drug Dependence;

    Sammanfattning : A new group of anabolic androgenic steroid (AAS) users has developed during the last two decades. This group consists primarily of young men interested in improving their physical appearance. Within this group, AAS are sometimes used together with other illicit drugs, alcohol and nicotine.

  5. 4. The birth and growth of the protein folding nucleus : Studies of protein folding focused on critical contacts, topology and ionic interactions

    Författare :Linda Hedberg; Mikael Oliveberg; Christopher Johnson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein folding; protein stability; two-state folding; chevron plot; transition-state movements; Hammond behaviour; topology; electrostatic interactions; pH dependence; mass-action; protein engineering; pKa; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : Proteins are among the most complex molecules in the cell and they play a major role in life itself. The complexity is not restricted to just structure and function, but also embraces the protein folding reaction. LÄS MER

  7. 5. Photosynthetic Oxygen Evolution - EPR studies of the manganese cluster of photosystem II

    Författare :Sindra Peterson Årsköld; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; S2 state; second cycle; Biochemistry; Metabolism; Biokemi; metabolism; S0 state; light-adaptation; pulsed EPR; methanol; relaxation; microwave power saturation; S-cycle; Oxygen-evolving complex; Water-oxidizing complex;

    Sammanfattning : In this thesis, a new electron paramagnetic resonance (EPR) signal from photosystem II is presented. The signal is shown to originate from the S0 oxidation state of the oxygen-evolving complex (OEC). LÄS MER
