  1. 11. 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

  3. 12. Cellulose Dissolution and Amphiphilicity : Insights on the Emulsion Formation and Stabilization

    Författare :Carolina Costa; Magnus Norgren; Håkan Edlund; Orlando Rojas; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : An amphiphilic polymer is expected to adsorb at the oil-water interface and be capable of stabilizing emulsions. Cellulose derivatives, cellulose nanoparticles and regenerated cellulose particles show an intrinsic amphiphilic character by self-assembling at oil-water interfaces and stabilizing emulsions without the aid of surfactants or any other co-stabilizers.

  4. 13. 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.

  5. 14. Perfluorocarbon microdroplets stabilized by cellulose nanofibers : Toward ultrasound-mediated diagnostics and therapy

    Författare :Ksenia Loskutova; Dmitry Grishenkov; Anna Justina Svagan; Gaio Paradossi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultrasound; acoustic droplet vaporization; phase-change contrast agent; Pickering emulsion; cellulose nanofiber; Ultraljud; akustisk droppförångning; kontrastmedel med fasförändring; Pickeringemulsion; cellulosananofiber; Teknik och hälsa; Technology and Health;

    Sammanfattning : Ultrasound contrast agents consist of gas-filled micrometer-sized bubbles that are injectedinto the blood stream. Ultrasound contrast agents are an invaluable tool for ultrasound imaging of the cardiac muscle and highly vascularized structures such as kidneys and the liver. LÄS MER

  7. 15. Starch stabilized Pickering emulsions : Colloidal starch particles and their effects on emulsion properties

    Författare :Hisfazilah Saari; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :Starch granules; Pickering emulsions; colloidal particles; sedimentation; acid hydrolysis; cold gelatinization; dissolution; non-solvent precipitation; nanoparticles;

    Sammanfattning : Particles can be used to stabilize multi-phase systems known as Pickering emulsions. The aim of this thesis was to investigate how starch particles affect emulsion properties. Starch granules were used individually as well as in binary mixtures. LÄS MER
