  2. 1. Chemical intolerance : disability and health aspects from a biopsychosocial perspective

    Author : Anna Söderholm; Ingrid Liljelind; Steven Nordin; Berit Edvardsson; Christer Jansson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chemical intolerance; multiple chemical sensitivity; sensory hyperreactivity; environmental intolerance; International Classification of Functioning; Disability and Health ICF ; questionnaire development; reliability; validity; coping; lived experience; mixed method; Public health; folkhälsa;

    Abstract : Background: Chemical intolerance (CI) is a term used for individuals experiencing symptoms triggered by odorous and pungent substances such as perfume, cleaning agents, mold smell and tobacco smoke. The prevalence of CI range from 0.5-52% depending on definition, and it is overrepresented among women. READ MORE

  4. 2. Single and Accumulative Electron Transfer – Prerequisites for Artificial Photosynthesis

    Author : Susanne Karlsson; Leif Hammarström; Hans-Christian Becker; Devens Gust; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Artificial photosynthesis; Photoinduced charge separation; Electron transfer; Energy transfer; Accumulative electon transfer; Donor-acceptor; Ruthenium; Linear arrays; Chemical physics; Kemisk fysik; Kemi med inriktning mot kemisk fysik; Chemistry with specialization in Chemical Physics;

    Abstract : Photoinduced electron transfer is involved in a number of photochemical and photobiological processes. One example of this is photosynthesis, where the absorption of sunlight leads to the formation of charge-separated states by electron transfer. READ MORE

  6. 4. Structural Transitions in Helical Peptides : The Influence of Water – Implications for Molecular Recognition and Protein Folding

    Author : Martin Lignell; Hans-Christian Becker; Kaare Teilum; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein dynamics; protein folding; molten globule; time-resolved fluorescence spectroscopy; CD spectroscopy; molecular recognition; structure-function paradigm; Chemical physics; Kemisk fysik; Physical Chemistry; Fysikalisk kemi;

    Abstract : Fluctuations in protein structure are vital to function. This contrasts the dominating structure-function paradigm, which connects the well-defined three-dimensional protein structure to its function. However, catalysis is observed in disordered enzymes, which lack a defined structure. READ MORE

  7. 5. Modern Computational Physical Chemistry : An Introduction to Biomolecular Radiation Damage and Phototoxicity

    Author : Jorge Llano; Leif A. Eriksson; Ulf Ryde; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; statistical mechanics; biophysical chemistry; interface; surface thermodynamics; bioelectrochemistry; ionizing radiation; radiation therapy; condensed matter; computational chemistry; nucleic acids; radiation damage; electrode potential; electronic transport; photochemistry; strand break; photodynamic action; cytostatic; solvation; solvated electron; absolute potential; chemical potential; Biologi; Biology; Biologi;

    Abstract : The realm of molecular physical chemistry ranges from the structure of matter and the fundamental atomic and molecular interactions to the macroscopic properties and processes arising from the average microscopic behaviour.Herein, the conventional electrodic problem is recast into the simpler molecular problem of finding the electrochemical, real chemical, and chemical potentials of the species involved in redox half-reactions.
