  2. 11. Production and application of fine fractions made of chemical pulp for enhanced paperboard strength

    Author : Elisabeth Björk; Per Engstrand; Mark Martinez; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : For all kinds of paperboard packages, the bending stiffness of the paperboard is a crucial property. In multi-ply folding boxboard (FBB) grades, this is obtained by placing different stocks in the outer and centre plies of the board. In the outer plies, a stock with a high tensile stiffness is used, typically made from refined kraft pulp fibres. READ MORE

  4. 12. Applications for Molten Carbonate Fuel Cells

    Author : Ivan Rexed; Göran Lindbergh; Carina Lagergren; Michel Cassir; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Molten Carbonate Fuel Cell MCFC ; poisoning; electrolyte degradation; SO2; Electrochemical Impedance Spectroscopy EIS ; CO2 separation; button cell set-up; reversible molten carbonate fuel cell; high temperature electrolysis.; Chemical Engineering; Kemiteknik;

    Abstract : Molten Carbonate Fuel cells are high temperature fuel cells suitable for distributed generation and combined heat and power, and are today being installed on commercial basis in sizes from 100kW to several MW. Novel applications for MCFC which have attracted interest lately are MCFC used for CO2 separation from combustion flue gas, and high temperature electrolysis with reversible fuel cells. READ MORE

  5. 13. Marine silicon cycle through the Cenozoic

    Author : Guillaume Fontorbe; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Si isotopes; Paleogene; PETM; glacial-interglacial; ocean circulation;

    Abstract : Silicon (Si) cycle is one of Earth's major biogeochemical cycles. Furthermore, the dissolved form of Si (DSi) is an essential nutrient for both terrestrial and marine ecosystems. READ MORE

  6. 14. Experimental studies of large particles in Newtonian and non-Newtonian fluids

    Author : Sagar Zade; Luca Brandt; Fredrik Lundell; Ellen Longmire; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulence; finite-size; particle-laden flows; duct flow; pipe flow; viscoelastic fluid; viscoplastic fluid; Engineering Mechanics; Teknisk mekanik;

    Abstract : In everyday human life, laminar flow is arguably an exception whereas turbulent flow is the norm. Yet, the former has been much better understood, naturally since laminar flow renders itself to treatment in a relatively easier fashion compared to turbulence with its chaotic dynamics across multiple scales in space and time.

  7. 15. Cleaning of ultra-high temperature milk fouling -Structural and compositionl changes

    Author : Carin Hagsten; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Fouling is the deposit of proteins and minerals formed on equipment surfaces during the heat treatment of dairy products. The concentrations of the components and the structure of the fouling reflect the processing conditions used. The use of a higher processing temperature, e.g. READ MORE
