  1. 6. Disintegration of Lime Mud Particles during the Causticizing Operation

    Författare :Pia Tiljander; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CaCO3; Ca OH 2; CaO; lime mud; mixing; particles; slaking; causticizing; disintegration; impeller;

    Sammanfattning : It is of essential importance that the white liquor used in processing wood chips to produce pulp in the sulphate pulp process is of high and uniform quality. The white liquor is, together with lime mud, produced in the causticizing plant where sodium carbonate is causticized with lime, slaked in green liquor. LÄS MER

  3. 7. Harnessing Mesoporous Spheres - transport studies and biotechnological applications

    Författare :Jovice Boon Sing Ng; Lennart Bergström; Frank Caruso; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mesoporous; spheres; particles; CLSM; TEM; controlled-release; molecular transport; lipid membrane; enzyme; intraparticle; lipase; solid support; Inorganic chemistry; Oorganisk kemi; materialvetenskap; Materials Science;

    Sammanfattning : Applications in controlled release and delivery calls for a good understanding of molecular transport within the carrier material and the dominating release mechanisms. It is clear that a better understanding of hindered transport and diffusion of guest molecules is important when developing new porous materials, e.g. LÄS MER

  5. 9. WHAT ARE THE CHARACTERISTICS OF AIRBORNE PARTICLES THAT WE ARE EXPOSED TO? Focus on Indoor Environments and Emissions from Biomass Fired District Heating

    Författare :Aneta Wierzbicka; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; particles; indoor environments; biomass combustion;

    Sammanfattning : Ambient fine particulate matter PM2.5 (particles with a diameter smaller than 2.5 μm) has been associated with cardiovascular and respiratory morbidity and mortality. It has been shown that biomass burning for heat production purposes can generate large amounts of fine particles. LÄS MER

  7. 10. Acoustic separation of submicron particles in gaseous flows

    Författare :Ramin Imani Jajarmi; Laszlo Fuchs; Etienne Robert; Klas Engvall; Martin Wiklund; KTH; []
    Nyckelord :Acoustic; submicron particles; gaseous flows; separation; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : The separation of submicron particles suspended in gaseous flows is a problem of great importance and is the subject of sustained research efforts. This is motivated by several challenges presented by modern science and technology requiring high separation efficiencies for submicron particles.
