  2. 6. Development and Stabilization of Hybrid Structure of Asphaltene and Graphene

    Author : Govin Induchoodan; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Non-covalent functionalization; functionalized graphene; asphaltene aggregates; ;

    Abstract : Petroleum and its derivatives, such as bitumen, are complex colloidal system. Their chemical behavior is influenced by various internal and external factors. Adding graphene derivatives to this system will only increase its complexity, thus it must be carefully considered to ensure successful integration. READ MORE

  4. 7. Separation of Proteins with Capillary Electrophoresis in Coated Capillaries with and without Electroosmosis : Studies on Zone Broadening and Analytical Performances

    Author : Sheila Mohabbati; Douglas Westerlund; Bo Karlberg; Uppsala universitet; []
    Keywords : Pharmaceutical chemistry; Capillary electrophoresis; capillary coatings; proteins; zone broadening; zone sharpening; efficiency; resolution; protein-surface adsorption; protein-buffer interaction; analytical performance; Farmaceutisk kemi;

    Abstract : Proteins have such structural features that they may interact with different types of surfaces by all possible forces, i.e., electrostatic, hydrogen bonding, hydrophobic. In this thesis two different types of coatings for fused silica capillaries aimed to eliminate such interactions have been studied. READ MORE

  5. 8. Characterising Halogen Bonding in a Cooperative Model System

    Author : Stefan Peintner; Mate Erdelyi; Anja Sandström; Uppsala universitet; []
    Keywords : Halogen Bond; NMR; peptide; conformation; RDC; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Abstract : Non-covalent interactions are the main driving factor for secondary structure formation of biomacromolecules and are of enormous importance for the direction of molecular recognition events, for example those of importance for drug discovery. Profound understanding of these interactions is of vital importance to achieve high affinity and selectivity of a ligand to a chosen target. READ MORE

  6. 9. Shape Matters : Characterization of Weak Interactions and Macrocycles by Conformational Analysis

    Author : Stefan Peintner; Máté Erdélyi; Oliver Zerbe; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : When studying conformational ensembles, it is most challenging to identify and characterize rapidly interconverting individual conformers. A precise description of the structural dynamics, however, rewards viable knowledge on conformation stabilizing forces as well as on the impact of external influences on the conformer composition.

  7. 10. Lignin-carbohydrate complexes: Model compounds synthesis

    Author : Filip Nylander; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lignin-carbohydrate complex; lignin model compounds; lignocellulose;

    Abstract : In lignocellulose there is a recalcitrant interaction by covalent and non-covalent bonds called the lignin-carbohydrate complex. This interaction has been the subject of studies trying to unveil its chemical structure, to understand the mechanims involved in its formation and to determine its influence on practical applications such as the process of turning biomass into ethanol.
