    Författare :Mathias Ohlin; Martin Viklund; Hans Hertz; Peter Glynne-Jones; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; 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

    Författare :Lillie Cavonius; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURAL SCIENCES; 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

    Författare :Jing Dai; Istvan Furo; Peter Griffiths; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; 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

    Författare :John Janiak; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 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. Protein isolation from herring (Clupea harengus) using the pH-shift process - Protein yield, protein isolate quality and removal of food contaminants

    Författare :Sofia Marmon; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; AGRICULTURAL SCIENCES; precipitation; acid; gelation; in vitro digestion; solubilization; herring; protein; salt solubility; pH; lipids; alkaline; transmission electron microscopy; dioxins;

    Sammanfattning : Herring (Clupea harengus) contain valuable proteins but is difficult to process into high-quality foods due to its small size and high content of bones, heme-proteins and lipids. Herring is among the most abundant fish species in the world, but is currently utilized largely for fish meal and oil production. LÄS MER
