  1. 6. Microcalorimetric methods for direct measurement of solubility and solvent activity

    Författare :Dennis Berling; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; enthalpy of solution; solubility; solvent fugacity; solvent activity; Isothermal calorimetry; vapour pressure; Chemistry; Kemi;

    Sammanfattning : New calorimetric methods for direct measurement of solubility and solvent activity are presented. The classical role of calorimetry for measurements of enthalpic parameters is abandoned and the technique is instead used for assessing thermodynamic quantities related to the chemical potential of a substance in a solution.

  3. 7. Development and characterisation of protecting groups that enhance the solubility of synthetic peptides : Methods to improve the aqueous solubility of hydrophobic peptides

    Författare :Karolina Wahlström; Anders Undén; Fernando Albericio; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Solid phase peptide synthesis; Fmoc chemistry; solubility problems; tryptophan; tyrosine; Nmec; Nmbu; Bioorganic chemistry; Bioorganisk kemi; Neurochemistry and Molecular Neurobiology; neurokemi med molekylär neurobiologi;

    Sammanfattning : Chemical synthesis of peptides is generally performed by solid phase peptide synthesis (SPPS). Although SPPS is a rapid and convenient method to prepare peptides, the major methodological problem in SPPS is related to solvation/solubility. LÄS MER

  5. 9. On the Solubility of Wood Hemicelluloses in Water and its Influence on the Adsorption at Cellulose/Water Interfaces

    Författare :Saina Kishani; Lars Wågberg; Bernard Cathala; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood; Hemicellulose; Solubility; Adsorption; Interaction; Cellulose; Size distribution;

    Sammanfattning : Hemicelluloses are a group of natural polysaccharides and one of the main components of wood. The availability and biodegradability of these polymers have created a great interest in developing new bio-based materials or composites from these materials for different end-use purposes. LÄS MER

  7. 10. On the solubility of radium sulfate and carbonate

    Författare :Artem Matyskin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dissolution; thermodynamics; radium sulfate; radium carbonate; solubility product; precipitation;

    Sammanfattning : Radium is one of the most toxic elements and its concentration in different human activities and migration from man-made wastes provokes a strong interest in environmental science. To be able to model the migration process, reliable experimental thermodynamic data of radium compounds are needed. LÄS MER
