  1. 1. Eco Friendly Composites Prepared from Lactic Acid Based Resin and Natural Fiber

    University essay from Högskolan i Borås/Ingenjörshögskolan (IH)

    Author : Nima Esmaeili; Shahrzad Javanshir; [2014-01-28]
    Keywords : Biobased thermoset; thermoset poly lactic acid; biobased composite; natural fiber; viscose;

    Abstract : Lactic acid based thermoset were synthesised by reacting lactic acid with glycerol andfunctionalizing lactic acid branches by methacrylic anhydride. Resins with different chainlength were prepared and their thermo mechanical properties were examined through DMAanalysis and their molecular structures were analyzed by NMR method and their viscositywere investigated through rheometry analysis and three monomers were selected as the bestchain length.

  3. 3. Tribological Performance of Different Coating-lubricant Systems

    University essay from Luleå/Department of Engineering Sciences and Mathematics

    Author : Xin He; [2012]
    Keywords : ;

    Abstract : Diamond-like carbon (DLC) coatings on steel are used to protect mechanical components, to improve lubrication properties such as anti-wear and friction reduction under certain operating conditions. The objectives of this work are (1) to evaluate the compatibility of lubricant with DLC in the boundary lubrication regime by laboratory tribo-test (2) to investigate lubrication mechanism using instrumental analysis.

  4. 4. Simulation of propionaldehyde production from glycerol

    University essay from Lunds universitet/Kemiteknik

    Author : Laura Malek; [2012]
    Keywords : Propionaldehyde; Glycerol; Aspen Plus®; Economic evaluation; Technology and Engineering;

    Abstract : The rising prices of fossil fuel, combined with increasing glycerol availability, thanks to increasing biodiesel production, have made glycerol more economically interesting to use as a starting material in various processes. This article will present and evaluate a new process developed by Biofuel-solutions for production of propionaldehyde from glycerol via acrolein. READ MORE

  5. 5. Composition and Application Potentials of Scandinavian Tunicates

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Masoumeh Hassanzadeh; [2011]
    Keywords : Tunicate; Ciona intestinalis; Clavelina lepadiformis; Cellulose whiskers; biofuel;

    Abstract : Marine ecosystems can be a promising reservoir of various kinds of chemical components, applicable as pharmaceutical materials, food, cosmetics, nutraceuticals, and others for different industry. As an example, Tunicates, a group of marine animals, have been attracted a lot of attention in medical application, food market, water pollution issues, and Cellulose nanomaterial production due to their consisting of chemical compounds such as cellulose, amino-sugars, and proteins or protein-polysaccharide complexes e.
