  1. 1. Ultrasonic Fluid and Cell Manipulation

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Mathias Ohlin; KTH.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 3D cell culture; Acoustic streaming; Acoustofluidics; Cell manipulation; High-resolution imaging; Multi-well; Microplate; Natural killer cell; Piezo; Radiation force; Solid tumor; Solubilization; Spheroid; Standing wave; Temperature control; Transducer; Trapping; Ultrasonic; Physics; Fysik; Biologisk fysik; Biological Physics;

    Sammanfattning : During the last decade, ultrasonic manipulation has matured into an important tool with a wide range of applications, from fundamental cell biological research to clinical and industrial implementations. The contactless nature of ultrasound makes it possible to manipulate living cells in a gentle way, e.g. LÄS MER

  2. 2. Fractionation of lipids and protein from the microalga Nannochloropsis oculata

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Lillie Cavonius; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; food processing; lipids; pH-shift process; n 3 polyunsaturated fatty acids; solubilization; acid; proteins; Nannochloropsis oculata; alkaline; microalgae; precipitation; in vitro digestion;

    Sammanfattning : To feed Earth’s growing population, microalgae have been proposed as a source of protein and long-chain n-3 polyunsaturated fatty acids (LC n-3 PUFAs). Currently, microalgae are mainly sold either as whole biomass, or the economically valuable LC n-3 PUFA fraction is extracted with organic solvents. LÄS MER

  3. 3. Adsorption, aggregation and phase separation in colloidal systems

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Jing Dai; KTH.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NMR; chemical shift; spin relaxation; self-diffusion; micelle; core freezing; segregation; solubilization; release; adsorption; binding; surfactant; carbon nanotube; block copolymer; dispersion; competitive adsorption; nanocomposite; Kemi; Chemistry;

    Sammanfattning : The thesis presents work regarding amphiphilic molecules associated in aqueous solution or at the liquid/solid interface. Two main topics are included: the temperature-dependent behavior of micelles and the adsorption of dispersants on carbon nanotube (CNT) surfaces. LÄS MER

  4. 4. Phase Behavior and Solution Properties of Aqueous Polyion-Surfactant Ion Systems

    Detta är en avhandling från Department of Chemistry, Lund University

    Författare :John Janiak; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymer-surfactant association; complex salt; nonionic surfactant; poly acrylic acid ; poly methacrylic acid ; copolymer; polymeric counterion; decyl betainate; phase behavior; solubilization; mixed micelle; hydrolysis; release; liquid crystal; nanoparticles; thermosresponsive; C12E8; C12E5;

    Sammanfattning : Polyelectrolytes and oppositely charged surfactants interact through attractive electrostatic forces, which in many cases lead to phase separation already at low total concentrations. During the past 10-15 years investigations of these systems have been simplified through the use of complex salts that consist of surfactants with polymeric counterions in a 1:1 charge stoichiometry (no excess simple counterions present).

  5. 5. An Investigation of Thermogelling Aqueous Systems of Ethyl(HydroxyEthyl)Cellulose and Ionic Surfactants

    Detta är en avhandling från Department of Food Technology, Lund University

    Författare :Katarina Lindell; [1996]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymer-polymer association; HS-DSC; SANS; solubilization; dexamethasone; timolol maleate; in vitro release; thermoreversible gelation; phase diagram; cloud point; Ethyl hydroxyethyl cellulose; ionic surfactants; Livsmedelsteknik; Food and drink technology;

    Sammanfattning : Aqueous solutions of a particular type of the nonionic cellulose derivative ethyl(hydroxyethyl)cellulose (EHEC) may form thermoreversible gels in the presence of ionic surfactants. Low-viscous solutions can be transformed to clear, stiff gels as the temperature is increased. LÄS MER
