  1. 1. 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

  3. 2. Emulsion formation and stability - Impact of the dispersed state of the emulsifier on emulsification

    Författare :Emma Magnusson; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Emulsion; phospholipid; dispersed state; field flow fractionation; freeze-thaw stability;

    Sammanfattning : Emulsions find a variety of applications in for example food, cosmetics and pharmaceutical preparations. In order to obtain emulsions with desired properties it is important to understand how different factors, such as the properties of the emulsifier and the emulsification procedure, impact the final emulsion properties.

  4. 3. Multifunctional Carbon Foams by Emulsion Templating : Synthesis, Microstructure, and 3D Li-ion Microbatteries

    Författare :Habtom Desta Asfaw; Kristina Edström; Leif Nyholm; John R. Owen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Battery; Carbon; Electrochemical; Electrodeposition; Emulsion; Energy; Exfoliation; Foam; Lithium; Microbattery; Multifunctional; Nanoparticles; Polyaniline; Polymer; Power; Sol-gel; Storage; Structured; Three-dimensional; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : Carbon foams are among the existing electrode designs proposed for use in 3D Li-ion microbatteries. For such electrodes to find applications in practical microbatteries, however, their void sizes, specific surface areas and pore volumes need be optimized. LÄS MER

  5. 4. Water-in-diesel emulsion and microemulsion fuels: composition, structure and effect on emissions

    Författare :Anna Lif; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NOx; microemulsion; combustion; diffusometry; alternative fuels; emission; emulsion; Fischer-Tropsch; MFC; PM; microfibrillated cellulose; NMR; surfactant; soot; diesel;

    Sammanfattning : Water-in-diesel fuels, as emulsions and microemulsions, give reduced emissions of nitrogen oxides (NOx) and particulate matter (PM) in combustion in diesel engines compared to regular diesel. These fuels can contribute to an improved local environment in densely populated areas as they can replace regular diesel in existing vehicles without any engine modification requirements. LÄS MER

  7. 5. Starch Pickering Emulsions : Process and Encapsulation Stability

    Författare :Ali Marefati; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :Starch granules; Pickering emulsions; Encapsulation; Freeze-thaw stability; Freeze-drying; In vitro digestion; In vitro intestinal lipolysis;

    Sammanfattning : The emulsion stabilization functionality of surfactants and biopolymers can be replaced by solid particles adsorbed at the interface, where they create a category of emulsions known as Pickering emulsions. Recently, health and environmental concerns have led to new market demand for natural, biodegradable and renewable sources of ingredients. LÄS MER
