  1. 16. Properties of modified starches and their use in the surface treatment of paper

    Författare :Anna Jonhed; Lars Järnström; Ann-Charlotte Eliasson; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Surface treatment of paper; hydrophobically modified starches; temperature-responsive starch; inclusion complexes; barrier properties; Surface engineering; Ytbehandlingsteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : The papermaking industry uses a large amount of starch each year, both as a wet-end additive and as a rheological modifier in surface sizing and coating colors. It is important to be able to reduce the amount of chemicals used in the papermaking and surface treatment process, to reduce costs and to make the process even more efficient. LÄS MER

  3. 17. Tailoring residue-derived carbon materials for the removal of wastewater contaminants : adsorption and surface properties

    Författare :Mirva Niinipuu; Stina Jansson; Jean-Francois Boily; Erik Rosenbaum; Magnus Bergknut; Capucine Dupont; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Adsorption; hydrochar; HTC; chemical activation; wastewater; pharmaceuticals; metals; surface properties; biobased residues;

    Sammanfattning : The availability of effective, low-cost wastewater treatment is necessary for increased water recycling and the prevention of environmental pollution on a global scale. Adsorption on activated carbons is commonly applied in wastewater treatment, but the high cost of conventional activated carbons limits the use of this technique. LÄS MER

  4. 18. Surface-Densified Wood : From Laboratory-Scale Research Towards a Competitive Product

    Författare :Benedikt Neyses; Dick Sandberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Science and Engineering;

    Sammanfattning : For many decades, humans have been consuming more resources than the world has to offer in the long run. Increasing the use of renewable materials, such as wood, is essential if we are to achieve a sustainable use of the resources available to us. LÄS MER

  5. 19. Lithium titanate as anode material in lithium-ion batteries : -A surface study

    Författare :Tim Nordh; Kristina Edström; Daniel Brandell; Carl Tengstedt; Carla Puglia; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; titanate battery anode SEI; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : The ever increasing awareness of the environment and sustainability drives research to find new solutions in every part of society. In the transport sector, this has led to a goal of replacing the internal combustion engine (ICE) with an electrical engine that can be powered by renewable electricity. LÄS MER

  7. 20. Numerical and experimental investigations of fluid-surface interaction

    Författare :Aidan Rinehart; Shervin Bagheri; Ugis Lacis; Anna-Lena Ljung; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; porous media; Brinkman equation; surface; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning :  Fluid-structure interactions play a central role in an overwhelming number of physical phenomena. All fluid dynamic students are familiar with the common assumption of a "smooth boundary". While this assumption often is enough to provide a high level understanding of the dynamics and physics at hand in practice this is not true. LÄS MER
