  1. 21. Advances in Separation Science : . Molecular Imprinting: Development of Spherical Beads and Optimization of the Formulation by Chemometrics

    Författare :Henrik Kempe; Anders Colmsjö; Ulrika Nilsson; Jan Åke Jönsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chromatography; Parameter estimation; Diffusion; Molecularly imprinted polymer; Suspension polymerization; Chemometrics; Analytical chemistry; Analytisk kemi;

    Sammanfattning : An intrinsic mathematical model for simulation of fixed bed chromatography was demonstrated and compared to more simplified models. The former model was shown to describe variations in the physical, kinetic, and operating parameters better than the latter ones. LÄS MER

  3. 22. A microfluidic toolbox to fabricate, sort and characterize thermoresponsive colloidal molecules and their assemblies

    Författare :Feifei Peng; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microgels; Thermoresponsive Colloidal Molecules; Microfluidics; Self-Assembly; Microgels; Thermoresponsive Colloidal Molecules; Microfluidics; Self-Assembly;

    Sammanfattning : In this thesis we discuss the assembly of thermoresponsive microgel particles into small clusters, and their use as colloidal molecules with specific and directional interactions. The underlying goal is to use these particles as advanced building blocks for new types of self- assembled structures with novel or vastly improved properties, and as model particles for investigating fundamental problems in condensed matter physics.

  4. 23. Waterborne Alkyd-Acrylic Hybrids with High Solids Content -Preparation and Properties-

    Författare :Mehrnoush Jowkar Deriss; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biopolymers; Polymer technology; Polymerteknik;

    Sammanfattning : The work presented in this thesis concerns the preparation, characterization and film formation of a waterborne alkyd-acrylic hybrid system with high solids content of about 80 %. The alkyd-acrylic hybrids were prepared by slowly adding a linseed oil alkyd to an acrylic latex dispersion under stirring. LÄS MER

  5. 24. Short-Chain Fatty Acid Starch Stabilized Pickering Emulsions : Design, Properties and Applications

    Författare :Nabilah Binti Abdul Hadi; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Short-chain fatty acid starch; Physicochemical properties; Pickering emulsions; Starch modification; Emulsion stability; Starch hydrolysis; In vitro digestion; Lipolysis;

    Sammanfattning : Pickering emulsions are emulsions stabilized by solid particles. Particles with optimal dual wettability toward both of the oil and water phases, can be adsorbed onto the interface, thereby providing the stability of the emulsions. LÄS MER

  7. 25. NMR Self-Diffusion Studies and Stability Studies of Emulsions

    Författare :Ingrid Lönnqvist; LTH Ingenjörshögskolan vid Campus Helsingborg; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; coalescence; emulsion stability; size distribution; restricted diffusion; self-diffusion coefficient; self-diffusion PGSE NMR; surfactant; emulsifier; continuous phase; microemulsion; phase diagram; emulsion; multiple emulsion; cream; conductivity; Physics; Fysik; Chemistry; Kemi;

    Sammanfattning : The aim of this study is to characterize emulsion systems by self-diffusion PGSE NMR methods. The specifics of the emulsions studied are all taken from the literature and they are of the W/O or O/W type stabilized with different emulsifiers. LÄS MER
