  1. 1. Mechanisms of Biopolymer Solvation: Development of a two-component ionic liquid solvent system

    Författare :Susanne Bylin; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; ionic liquids; solvation; mechanism; xylan; lignin; cellulose; wood components;

    Sammanfattning : Ionic liquids are of potential interest in the processing of lignocellulosic biomass, and/or its components, for the purpose of producing renewable and value-added biomaterials. An understanding of how solvation can be achieved and the way in which the feedstock biopolymers are affected, however, needs to be gained prior to a viable implementation. LÄS MER

  2. 2. Toward Safer Energy Storage Solution by Development of Fluorine-Free Battery Electrolyte

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Elham Hosseini Bab Anari; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; sodium-ion batteries SIBs ; aqueous electrolyte; lithium-ion batteries LIBs ; safer electrolyte; fluorine-free salt;

    Sammanfattning : Portable electronic devices such as mobile phones, laptops, cameras and electronic vehicles (EVs) which contain lithium-ion batteries (LIBs), are indispensable part of our modern society. The safety of conventional electrolytes of LIBs, composed of fluorinated lithium salts and organic solvents is the source of some concerns. LÄS MER

  4. 4. Facilitating electron transfer in bioelectrocatalytic systems

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Alina Sekretaryova; Mats Eriksson; Mikhail Vagin; Anthony Turner; Evgeny Katz; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Bioelectrocatalytic systems are based on biological entities, such as enzymes, whole cells, parts of cells or tissues, which catalyse electrochemical processes that involve the interaction between chemical change and electrical energy. In all cases, biocatalysis is implemented by enzymes, isolated or residing inside cells or part of cells. LÄS MER

  5. 5. Recycling of TiO2 Pigments from Waste Paint: Process Development, Surface Analysis, and Characterization

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Mikael Karlsson; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Recycling; Recovery; Paint; Titanium dioxide; Waste.; Municipal solid waste handling; Pyrolysis; Pigment;

    Sammanfattning : Pigments are commonly used in paint, plastic and paper products and titanium dioxide (TiO2), the most important white pigment, accounts for approximately 70 % of the total volume of all pigments used today. Minerals containing TiO2 are relatively abundant in the earth’s crust. LÄS MER
