  2. 1. Hydrophilic Separation Materials for Liquid Chromatography

    Author : Petrus Hemström; Knut Irgum; Peter Schoenmakers; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chromatography; HILIC; Hydrophilic; Stationary phase; Chemistry; Kemi;

    Abstract : The main focus of this thesis is on hydrophilic interaction chromatography (HILIC) and the preparation of stationary phases for HILIC. The mechanism of HILIC is also discussed; a large part of the discussion has been adapted from a review written by me and professor Irgum for the Journal of Separation Science (ref 34). READ MORE

  4. 2. Functionalization of Synthetic Polymers for Membrane Bioreactors

    Author : Hamidreza Barghi; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioreactor; Functionalization; Hydrophilic; Membrane; Polyamide 46; Synthetic polymer; Resursåtervinning; Resursåtervinning; Resource Recovery;

    Abstract : Membrane bioreactors (MBRs) show great promise for productivity improvement and energy conservation in conventional bioprocesses for wastewater reclamation. In order to attain high productivity in a bioprocess, it is crucial to retain the microorganisms in the bioreactors by preventing wash out. READ MORE

  5. 3. Effect of solvents during material treatment applications : tuning hydrophilicity of silicone rubber and drug loading in mesoporous silica

    Author : Anna Hillerström; Jan van Stam; Lennart Piculell; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Solvents; liquid carbon dioxide; Interpenetrating Polymer Network IPN ; silicone rubber; hydrophilic; phase domains; mesoporous silica; ibuprofen; adsorption isotherms; release; Kemi; Chemistry;

    Abstract : Choosing the right solvent is critical for many industrial applications. A useful property for selection of solvents is their solubility parameters. This concept of solubility parameters is central to this thesis and has been used in two different case studies of material treatment applications. READ MORE

  6. 4. Microfluidics in Surface Modified PDMS : Towards Miniaturized Diagnostic Tools

    Author : Sara Thorslund; Fredrik Nikolajeff; Jonas Bergquist; Elisabeth Verpoorte; Uppsala universitet; []
    Keywords : Materials science; µTAS; micro total analysis system; PDMS; poly dimethylsiloxane ; microfluidics; heparin; blood filtration; on-chip; ESI-MS; desalting; QCM-D; biocompatible; CD4; capillary flow; lab-on-chip; microfabrication; enrichment; point-of-care; hydrophilic; oxidation; Materialvetenskap;

    Abstract : There is a strong trend in fabricating miniaturized total analytical systems, µTAS, for various biochemical and cell biology applications. These miniaturized systems could e.g. gain better separation performances, be faster, consume less expensive reagents and be used for studies that are difficult to access in the macro world.
