  1. 31. Cellulosic Thermal Insulation with Improved Water Resistance and Fire Retardancy

    Författare :Chao Zheng; Monica Ek; Dongfang Li; Lennart Salmén; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Bio-based; Cellulosic; Fire retardant; Thermal insulation; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Sweden is one of the largest countries by area in Europe, and almost 70% of it is covered by forest. These abundant forest resources benefit the Swedish bioeconomy, but the pulp and paper industry is facing the challenge of a decrease in the demand for printing paper due to a significant shift to electronic media; therefore, it is a priority to use pulp to produce alternative value-added products, such as thermal insulating materials in buildings.

  3. 32. Self assembly of surfactants and polyelectrolytes in solution and at interfaces

    Författare :Luis Alejandro Bastardo Zambrano; Per Claesson; Jan Skov Pedersen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Surfactant; polyelectrolyte; small–angle neutron scattering; static light scattering; dynamic light scattering; polyelectrolyte–surfactant association; protein; Surface and colloid chemistry; Yt- och kolloidkemi;

    Sammanfattning : This thesis focuses on the study of the interactions between polyelectrolytes and surfactants in aqueous solutions and at interfaces, as well as on the structural changes these molecules undergo due to that interaction. Small–angle neutron scattering, dynamic, and static light scattering were the main techniques used to investigate the interactions in bulk. LÄS MER

  4. 33. Anaerobic digestion of crop and waste biomass: Impact of feedstock characteristics on process performance

    Författare :Nges Ivo Achu; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic digestion; Biofertilizer; Renewable energy; Sustainable operation;

    Sammanfattning : Anaerobic digestion provides an array of positive environmental benefits such as reducing greenhouse gas emissions, replacing mineral fertilizers, producing renewable energy and treating waste. However, pitfalls in anaerobic digestion such as poor methane yields, process instability, process failure and regional shortages of feedstock have limited the full exploitation of the anaerobic digestion process.

  5. 34. Thermally Expandable Microspheres Prepared via Suspension Polymerization - Synthesis, Characterization, and Application

    Författare :Magnus Jonsson; Eva Malmström Jonsson; Søren Hvilsted; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thermally expandable microspheres; Polymer chemistry; Polymerkemi;

    Sammanfattning : Thermally expandable microspheres are polymeric core/shell particles in which a volatile hydrocarbon is encapsulated by a thermoplastic shell. When these microspheres are heated, they expand and increase their volume dramatically. LÄS MER

  7. 35. Nordiska ortnamn på -und

    Författare :Eva Nyman; Svante Strandberg; Thorsten Andersson; Börje Tjäder; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Scandinavian languages - general; onomastics; toponymy; hydronymy; nesonymy; place-names; place-name elements; place-name chronology; suffixes; Denmark; Norway; Sweden; Scandinavia; Germanic; Indo-European; Nordiska språk - allmänt; Scandinavian languages; Nordiska språk; nordiska språk; Scandinavian Languages;

    Sammanfattning : In this thesis, an investigation and classification of Scandinavian place-names in -und is undertaken. The thesis comprises two main sections: Part 1, containing a review of earlier research and discussions of broader issues, and Part 2, consisting of studies of, individual names, arranged inalphabetical order.
