  1. 1. New approaches to preparation of macroporous monoliths for use in liquid chromatography

    Författare :Anh Mai Nguyen; Knut Irgum; Tatiana B. Tennikova; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; monolith; polycondensation; dissolution-precipitation; epoxy-amine; poly-amide; nylon; emulsion polymerization; characterization; protein separation; liquid chromatography; Analytical chemistry; Analytisk kemi; analytisk kemi; Analytical Chemistry;

    Sammanfattning : High performance liquid chromatography (HPLC) is one of the major techniques in separat-ion sciences. Faster separation and higher efficiency are required to meet ever-growing demands. Despite numerous studies and achievements on improving mass transfer in particulate packings discontinuity seems to be the cornerstone drawback in their development. LÄS MER

  3. 2. Salting-out of Colloidal Latex Particles Grafted with Poly(ethylene glycol)

    Författare :Kristin Jonsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PEG; fluorinated colloids; monodisperse spheres; steric stability; emulsion polymerization; SAXS; crosslinking; salting-out; interfacial tension; SANS;

    Sammanfattning : Colloidal particles dispersed in a medium are important both in nature and in industry. The stability of colloidal particles is determined by the interactions between them and can be improved by steric stabilization. There is no conclusive understanding of how these sterically stabilized particles become unstable. LÄS MER

  5. 4. Heterogeneous Film-Forming Latexes : Preparation - Morphology - Mechanical Properties

    Författare :Ola Karlsson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; core-shell; particle morphology; heterogeneous latexes; particle size; crosslinking; hydrophilicity; poly isoprene-co-styrene-co-methacrylic acid ; monomer partitioning; internal particle viscosity; transmission electron microscopy TEM ; calorimetric reactor; two-stage; seeded emulsion polymerization; film morphology; mechanical properties; paper coating.; Polymer technology; biopolymers; Polymerteknik;

    Sammanfattning : This thesis describes the preparation of heterogeneous latexes, which may serve as binders in coating applications, and the characterization of these. The latexes were prepared in two-stage seeded emulsion polymerization. LÄS MER

  7. 5. Fabrication of Functional Molecularly Imprinted Materials using Nanoparticle Building Blocks

    Författare :Changgang Xu; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecularly imprinted polymers; magnetic susceptibility; click chemistry; PFPA; Pickering emulsion; chemical conjugation;

    Sammanfattning : Molecularly imprinted polymers (MIPs) have attracted great interest in many applications including bioseparation, chemical sensing, catalysis, drug delivery, etc. Recently, molecularly imprinted nanoparticles have become accessible due to a number of synthetic methods that have been developed.
