  2. 26. Materials Design for Paper Electrodes : A Papermaking Perspective on Electrode Fabrication

    Author : Patrik Isacsson; Isak Engquist; Magnus Berggren; Nadège Reverdy-Bruas; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Papermaking; Electrodes; Lignin; Nanocarbons; PEDOT:PSS;

    Abstract : The electrification and digitalization of our society has propelled the demand for energy storage solutions. High-end technologies have been developed to satisfy the requirements of demanding applications, such as electromobility and portable consumer electronics, which also increasingly find markets for less demanding applications.

  4. 27. On the effects of structure and function on protein evolution

    Author : Kristoffer Illergård; Arne Elofsson; Nir Ben-Tal; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein; structure; function; evolution; membrane; Biochemistry; Biokemi; Biochemistry; biokemi;

    Abstract : Many proteins can be described as working machines that make sure that everything functions in the cell. Their specific molecular functions are largely dependent on their three-dimensional structures, which in turn are mainly predetermined by their linear sequences of amino acid residues. READ MORE

  5. 28. A Novel Fiber Interaction Method for Simulation of Early Paper Forming

    Author : Gustav Kettil; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fiber suspension flow model; object-object interaction model; contact forces; lay down simulations; paper forming; immersed boundary methods; contact forces;

    Abstract : In the forming section of a paper machine, a fiber suspension is flowing down onto a forming fabric, and a paper structure is formed. By using computer simulations this process can be studied, attaining new knowledge helping to improve paper quality and machine efficiency. READ MORE

  6. 29. Dewatering aspects at the forming section of the paper machine : Rewetting and forming fabric structure

    Author : Björn Sjöstrand; Lars Nilsson; Christophe Barbier; David McDonald; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rewetting; forming fabric; forming section; dewatering; web dryness; high vacuum suction box; vacuum dewatering; forming fabric design; numerical model; Chemical Engineering; Kemiteknik;

    Abstract : The underlying motives of the research undertaken here are twofold: to obtain a deeper understanding of the dewatering mechanisms at the forming section of a papermaking machine and to develop numerical models that describe the flow through forming fabrics. More comprehensive knowledge of dewatering in the forming section allows suggestions to be made for improvements that reduce the amount of energy used in the process without affecting the quality of the end product.

  7. 30. Structure and dynamics of complex materials in the water-poor regime

    Author : Sanna Gustavsson; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydration; cellulose; dissolution; sugar surfactant; hydrated crystals; structure; dynamics; phase diagram; fuel cell; pulsed-field-gradient PFG spin-echo NMR; Polarization Transfer solid state NMR; PXRD; GVS; TGA; amphiphilic;

    Abstract : In the solid state, molecules are normally ordered in a specific structure. With time, and as a result of influence from the surroundings, solid materials can change their molecular and/or crystal structure and, as a consequence, obtain completely different properties. Water is particularly important in this respect. READ MORE
