  1. 1. Application of Raman and Fluorescence Spectroscopy to Single Chromatographic Beads

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Mina Larsson; Uppsala universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; agarose; chelating group; confocal Raman spectroscopy; confocal scanning laser microscopy; gold nanoparticles; ligand distribution; functional group; neodymium; polymer beads; Raman; SERS; surface-enhanced Raman spectroscopy; Kemi; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi;

    Abstract : Chromatography is a powerful technique, essential in chemical analyses and preparative separation in industry and research. Many different kinds of chromatographic material are needed, due to the large variety of applications. Detailed methods of characterisation are needed to design new chromatographic materials and understand their properties. READ MORE

  2. 2. Direct observation of biomolecule adsorption and spatial distribution of functional groups in chromatographic adsorbent particles

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anders Ljunglöf; Uppsala universitet.; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Confocal microscopy; confocal Raman spectroscopy; protein adsorption; ligand distribution; visualization; imaging; Bioteknik; TECHNOLOGY Bioengineering; TEKNIKVETENSKAP Bioteknik; Surface Biotechnology; ytbioteknik;

    Abstract : Confocal microscopy has been used as a tool for studying adsorption of biomolecules to individual chromatographic adsorbent particles. By coupling a fluorescent dye to protein molecules, their penetration into single adsorbent particles could be observed visually at different times during batch uptake. READ MORE

  3. 3. Hydrophobic surfaces: Effect of surface structure on wetting and interaction forces

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Petra M Hansson; KTH.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrophobic surface; superhydrophobic surface; atomic force microscopy; surface forces; capillary forces; cavitaion; surface roughness; friction; wetting; confocal Raman; contact angles; surface preparation; Langmuir-Blodgett;

    Abstract : The use of hydrophobic surfaces is important for many processes both in nature and industry. Interactions between hydrophobic species play a key role in industrial applications such as water-cleaning procedures and pitch control during papermaking but they also give information on how to design surfaces like hydrophobic mineral pigments.

  4. 4. Microstructure of spray dried particles at different scales of drying

    University dissertation from Lund University

    Author : Marine Nuzzo; Lunds universitet.; Lund University.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure; morphology; confocal Raman microscopy; phase segregation; spray drying;

    Abstract : Popular Abstract in English In our society powder is found to be a common state of material. Indeed, the powder state is found to be convenient to store and transport large quantities of material. One of the major techniques to produce powder is spray drying, also for thermally sensitive materials such as foods and pharmaceuticals. READ MORE
