    Sammanfattning : Crystallization of C60 and C70 from organic solution often leads to the formation of new solvates and other fullerene compounds. In the present thesis, a number of such solvates were obtained and their phase transitions studied using in situ "in solution" techniques. LÄS MER

  4. 3. Metal-Chelate Complexes in Alkaline Solution : On Recovery Techniques and Cellulose-based Hybrid Material Synthesis

    Författare :Alireza Eivazihollagh; Håkan Edlund; Magnus Norgren; Joakim Bäckström; Christian Ekberg; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : For decades, aminopolycarboxylate chelating agents have been extensively used in various industrial applications. The ability of chelating agents to form stable metal-chelate complexes is the main reason for using them to manage metal ions within water-based industrial processes. LÄS MER

    Sammanfattning : Forward modelling of electromagnetic induction data simulates the electric and magnetic fields within a computational domain for a given distribution of electromagnetic material properties and a given source of the electromagnetic field. The quantities of interest are the fields at receiver locations at the Earth's surface. LÄS MER

  7. 5. Poly(Ethylene Oxide) Based Bottle-Brush Polymers and their Interaction with the Anionic Surfactant Sodium Dodecyl Sulphate : Solution and Interfacial Properties

    Författare :Joseph Iruthayaraj; Per M. Claesson; Regine v. Klitzing; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PEO brush polymers; brush polymers; PEO; poly ethylene oxide ; polymer-surfactant; sodium dodecyl sulphate SDS ; Ellipsomtery; PEO-SDS interactions; Surface and colloid chemistry; Yt- och kolloidkemi;

    Sammanfattning : The aim of this thesis work is to study the physico-chemical properties of poly(ethylene oxide), PEO, based brush polymers both in solution and at solid/aqueous interfaces. The importance of studying the surface properties of brush polymers can be related to a broad spectrum of interfacial-related applications such as colloidal stability, lubrication, detergency, protein repellency to name a few.
