  1. 1. A study of finite-size, non-perturbative and anisotropic effects on the Lifshitz-van der Waals forces and torque with material dielectric responses from first-principles calculations

    Författare :Priyadarshini Thiyam; Clas Persson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lifshitz-van der Waals forces; Casimir torque; optical calculations with density functional theory; phosphorus; phosphorene;

    Sammanfattning : The van der Waals and the Casimir-Lifshitz forces are forces of attraction that exist between neutral polarizable bodies due to quantum fluctuations. They can be repulsive depending on the material properties and the geometry of the system. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  4. 3. Microbial adhesion and surface modifications of sulphide minerals relevant to flotation and flocculation

    Författare :Annamaria Vilinska; Ponisseril Somasundaran; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : Biological processes have been attracting attention in mineral processing industry due to their lower operating costs, environmental acceptability and flexibility in adaptation. Bio-hydrometallurgical methods to treat various sulphide and oxide ores have been developed during the years and these processes have been adopted by certain mineral industries. LÄS MER
