    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Titanium dioxide TiO2 ; Nanoparticles; Synthesis; Hydrolysis; Titanium tetrachloride TiCl4 ; Anatase; Brookite; DLS; ES-SMPS; XRD; Collective diffusion; Interfacial processes;

    Sammanfattning : Titanium dioxide (TiO2) nanoparticles were synthesized via the hydrolysis of TiCl4 in order to produce clean, surfactant-free oxide surfaces. By controlling the synthesis and aging conditions, stable particles with well-defined size distributions were obtained. LÄS MER

  4. 3. Nanoparticles in capillary electrophoresis : what are the benefits?

    Författare :David Malmström; Jonas Bergquist; Charlotta Turner; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi;

    Sammanfattning : Capillary electrophoresis is a technique that separate compounds based on charge and size. During the last two decades capillary electrophoresis (CE) and mass spectrometry (MS) has gained in interest, become more robust to use and able to separate neutral analytes. LÄS MER

  5. 4. Nanoparticle-based Capillary Electrochromatography - Separation of Small Molecules and Proteins

    Författare :Christian Nilsson; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanoparticles; Capillary Electrochromatography; Green Fluorescent protein; Pseudostationary Phase; Capillary Electrophoresis;

    Sammanfattning : The use of nanoparticle-based pseudostationary phases (PSPs) in capillary electrochromatography (CEC) for separation of small molecules and proteins is demonstrated. A continuous full filling approach is used where the nanoparticles are suspended in the electrolyte. LÄS MER

  7. 5. Nanoparticle-based capillary electrochromatography

    Författare :Peter Spégel; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Teknik; Technological sciences; Analytisk kemi; Analytical chemistry; Nanoparticles; Molecularly imprinted polymers; Capillary electrochromatography;

    Sammanfattning : This thesis concerns a highly efficient nanoparticle-based capillary electrochromatography separation technique and its coupling with mass spectrometric detection. From chromatographic theory, it is well known that the separation efficiency increases with decreasing particle size. LÄS MER
