  2. 16. Influence of Solvent Composition on Crystal Agglomeration of Paracetamol

    Author : Eva Ålander; Åke Rasmuson; Jean-Paul Klein; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; Kemiteknik; Chemical engineering; Kemiteknik;

    Abstract : Agglomeration is an important phenomenon which often controls the particle size distribution and morphology in the crystallization of organic compounds. In this thesis the influence of solvent composition on crystal agglomeration of paracetamol is investigated. READ MORE

    Abstract : Power transmission over long distances by using high voltage direct current (HVDC) cables is important for the transition from fossil energy to using renewable energy sources, e.g. wind, solar and water. READ MORE

  5. 18. Simulations of Simple Fluids and Surface Forces

    Author : Martin Trulsson; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular modeling; Surface Forces; Dielectric Constant; Charge Capacitance; Charge Regulation; Hypersphere; Statistical mechanics; Intermolecular interactions; Col- loidal Stability; Simulations; Fluids;

    Abstract : A considerable part of all chemistry in nature and in industry occurs in solvents. Sol- vents affect both the interactions and the reactions of the particles immersed in them. The work in this thesis concerns the properties of ionic and polar solvents, as well as the interactions between solutes and/or dispersed particles. READ MORE

  6. 19. Surface Modification of Cellulose-based Materials for Tailoring of Interfacial Interactions

    Author : Simon Utsel; Lars Wågberg; Simon Biggs; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The awareness of our need for a sustainable society has encouraged the search for renewable, high quality materials that can replace oil-based products. This, in combination with increased competition in the forest industry, has stimulated a lot of research into different types of wood-based materials where cellulose-rich fibers are combined with different types of polymers.
