  1. 1. Intramolecular Electronic Interactions in Photon Upconversion and Singlet Fission

    Författare :Fredrik Edhborg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Singlet Fission; Photon Upconversion; Intramolecular; Excitation Energy Transfer; Solar Energy Conversion;

    Sammanfattning : The sun provides our planet with an abundance of energy in the form of solar light – a continuous stream of photons. Increasing our direct utilization of solar energy will constitute a necessary part in our ongoing replacement of fossil fuels with energy sources free from greenhouse gas emissions. LÄS MER

  3. 2. Protein Interactions: Electrostatics and Ligand Binding

    Författare :Ingemar André; Biofysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biophysics; Molekylär biofysik; secondary structure formation; protein GB1; pKa values; pH stability; NMR; electrostatic interactions; M proteins; calbindin D9k; calcium binding; cooperativity; calmodulin; calbindin D28k;

    Sammanfattning : This thesis deals with Ca2+ binding to proteins, electrostatic interactions in and between proteins as well as inter- and intramolecular interactions. A computer program was developed to determine Ca2+ binding constants from experimental titration data of proteins. LÄS MER

  4. 3. Regulation of PKCalpha and the role of PKC in neuroblastoma cell migration

    Författare :Helena Stensman; Institutionen för translationell medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cytology; oncology; cancerology; Cytologi; Medicin människa och djur ; Medicine human and vertebrates ; neuroblastoma; cell migration; intramolecular interactions; autophosphorylation; Protein kinase C; onkologi; cancer;

    Sammanfattning : Members of the protein kinase C (PKC) family of serine/threonine kinases play critical roles in cellular regulation. Depending on differences in regulation, PKCs can be divided into classical (alpha, betaI, betaII and gamma), novel (delta, epsilon, eta and theta) and atypical (zeta and iota/lambda) isoforms.

  5. 4. Interactions between Wood Polymers in Wood Cell Walls and Cellulose/Hemicellulose Biocomposites

    Författare :Jasna Stevanic Srndovic; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic FTIR spectroscopy; viscoelasticity; orientation; Norway spruce; protein; glucomannan; xyloglucan; polymer interactions; pectin; imaging FTIR microscopy; primary cell wall; nanocomposite films; dynamic 2D FTIR spectroscopy; xylan; wood fibre; cellulose; secondary cell wall; DMA; lignin;

    Sammanfattning : A wood fibre is a complex multi component biocomposite that is hierarchically organised. The arrangement of a wood fibre on the ultrastructural level is highlycontrolled by the interactions between the main structural polymers, i.e. cellulose, various hemicelluloses and lignin, as well as in some parts also pectin and protein.

  7. 5. An Infrared Study of Intermolecular Interactions in Gaseous Hydrogen Bonded Molecular Complexes

    Författare :René Wugt Larsen; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; intermolecular potential energy surface; Physical chemistry; Fysikalisk kemi; synchrotron radiation; infrared absorption spectroscopy; intermolecular vibration; molecular complex; Intermolecular interactions; hydrogen bond;

    Sammanfattning : Intermolecular interactions are responsible for the deviations of gases from ideality, determine the three- dimensional structure and folding dynamics of biological molecules, and the binding of molecules to surfaces as in heterogeneous catalysis. The hydrogen bond is the most important intermolecular interaction. LÄS MER
