  2. 1. Drug Diffusion and Nano Excipient Formation Studied by Electrodynamic Methods

    Author : Ulrika Brohede; Maria Strømme; Göran Frenning; Hans Leuenberger; Uppsala universitet; []
    Keywords : Functional materials; drug release; electrodynamic methods; diffusion; Funktionella material;

    Abstract : New smart drugs demand new smart drug delivery systems and also new smart analysis methods for the drug delivery process and material characterization. This thesis contributes to the field by introducing a new electrodynamic approach for studying the drug diffusion proc-esses as well as the formation of a new type of drug delivery systems, the so called mesoporous nano excipients.

  4. 2. Design and analysis of a novel low loss homopolar electrodynamic bearing

    Author : Torbjörn A. Lembke; Chandur Sadarangani; Hannes Bleuler; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Homopolar bearing; Electrodynamic bearing; Induction bearing; Elektroteknik; Electrical engineering; Elektroteknik;

    Abstract : A novel homopolar electrodynamic bearing, together with a suitable permanent magnet drive, have been developed for high-speed applications where low losses and high reliability are essential and exclude the use of ball bearings, and yet where active magnetic bearings offer a too complex system solution. Considered applications are small turbomolecular vacuum pumps, and maintenance free flywheels for energy storage in remote telecom and satellite systems. READ MORE

  6. 4. Experimental studies of ice particle formation with tropospheric relevance

    Author : Erik Svensson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; heterogeneous nucleation; water; freezing; cloud droplets; levitation; electrodynamic balance; light scattering; oxalic acid; kaolinite; dinitrogen pentoxide;

    Abstract : In their fourth assessment report, the Intergovernmental Panel on Climate Change points out the influence of particles suspended in air, known as an aerosol, as the main uncertainty in the understanding of the climate system. Aerosols affect climate in a number of ways. READ MORE

  7. 5. Electrodynamic and Mechanical Spectroscopy Method Development and Analysis Relating to Materials with Biotechnological Applications

    Author : Ken Welch; Maria Strømme; Ragnar Ek; Bengt-Erik Mellander; Uppsala universitet; []
    Keywords : Engineering physics; Teknisk fysik;

    Abstract : Materials with biotechnological applications and materials that interact with the biological environment play an ever increasing role in our lives and society. In order to be able to tailor specific properties of these materials to suit their intended applications, it is important to gain a deeper understanding of the relationship between the material structure and its function.
