  2. 6. Interaction of magnetite with soluble silicates and bentonite : implications for wet agglomeration of magnetite concentrate

    Author : Xiaofang Yang; James McQuillan; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical Chemistry; Fysikalisk kemi; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : Iron ore green pellets are produced by agglomeration of moist magnetite concentrates. The quality of green pellets is essential for the transportability and metallurgical benefits of the final product. READ MORE

  4. 7. Studies of surfactant behaviour and model surfaces relevant to flotation deinking

    Author : Katarina Theander; Mark Rutland; Krister Holmberg; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Surface and colloid chemistry; Yt- och kolloidkemi;

    Abstract : The objective of this work was to investigate the behaviour of some model surfactants used in the deinking process, namely, sodium oleate and two ethoxylated nonionic surfactants (C12E6 and C14E6) as well as to investigate the suitability of various model substrates for mimicking interactions in technical systems. The influence of the adsorption to the air � water interface has been measured by means of equilibrium and dynamic surface tension measurements, as well as foaming experiments. READ MORE

  5. 8. Surface complexation at calcium mineral-water interfaces

    Author : Liuming Wu; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : Surface reactions occurring at solid-water interfaces in calcium mineral-ligands systems have been studied. Both hydrous apatite and fluorite surfaces show clear amphoteric properties. An ion exchange process between lattice ions of F- on fluorite and OH- ions in bulk solution is discovered. READ MORE

  6. 9. Particle interactions at the nanoscale : From colloidal processing to self-assembled arrays

    Author : Bertrand Faure; Lennart Bergström; Albert Philipse; Stockholms universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Colloidal processing; nanoparticles; colloidal forces; titania; iron oxide; Hamaker constant; surface modification; rheology; Monte Carlo simulations; collective properties; superparamagnetism; finite-size effects; Materials Chemistry; materialkemi;

    Abstract : Nanostructured materials are the next generation of high-performance materials, harnessing the novel properties of their nanosized constituents. The controlled assembly of nanosized particles and the design of the optimal nanostructure require a detailed understanding of particle interactions and robust methods to tune them. READ MORE

  7. 10. Poly (3-hydroxybutyrate) from a moderate halophile: production and modification for new applications

    Author : Marlene Munoz; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biopolymers; polyhydroxyalkanoates; polyhydroxybutyrate; moderate halophile; Halomonas boliviensis; fermentation; recovery; thermally induced phase separation; scaffolds; covalent modification; hydrophobic ion pairing; polyethylenemine; lysozyme.;

    Abstract : Polyhydroxybutyrate (PHB) is a homopolymer belonging to the family of biopolyesters, polyhydroxyalkanoates (PHA) produced by different bacteria and archaea as intracellular granules often under conditions of metabolic stress due to a limited supply of essential nutrients. The properties of the PHAs are similar to those of polyethylene and polypropylene and can hence replace these fossil based polymers in a large variety of applications. READ MORE
