  2. 6. Competence, Styles, and Quality in Everyday Decision Making

    Author : Martin Geisler; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; decision making; decision-making competence; decision-making styles; decision quality; decision outcome; social skills; time-approach;

    Abstract : This thesis had three aims. First, it explored the benefits of expanding the existing cognitively-oriented definition of individual differences in decision-making competence (i.e., measured by performance on traditional decision-making tasks) by including decision-related aspects of social skills and time-approach.

  4. 7. Comparative Study of different Recycling Methods for the Electrolyte Recovery from spent Li-Ion Batteries

    Author : Nils Zachmann; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spectroscopy analysis; recycling process; electrolyte; thermal treatment; lithium-ion battery; supercritical carbon dioxide extraction; exhaust-gas emission characterization;

    Abstract : The state-of-the-art Li-Ion battery (LiB) recycling strategies focus mainly on recycling of the electrode materials, i.e., Li, Co, Mn, Ni, Al, and Cu. READ MORE

  5. 8. Lipase-Mediated Syntheses of Trimethylolpropane-Based Biolubricant and Cyclic Carbonate

    Author : Amin Bornadel; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Abstract Biocatalysis is considered as benign and efficient alternative to chemical catalysis for organic syntheses. Lipases are the most versatile biological catalysts implemented so far with great potential for production of different chemicals and materials in non-conventional reaction media. READ MORE

  6. 9. Towards sugar- and lignin-based polyesters and polyurethanes with enhanced properties

    Author : Niklas Warlin; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polyesters; Polyurethane; Bio-based Materials; HMF; Recycling; Vanillin;

    Abstract : The enormous production and consumption of fossil-based plastics has caused severe environmental challenges such as pollution of the ocean, increased CO2-emissions, and various health problems. Many ofthese concerns are intimately connected to the use of fossil fuels in the production of polymers. READ MORE

  7. 10. (In-)Stability of LiPF6-based Electrolytes for Lithium-ion Batteries

    Author : Susanne Wilken; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; FTIR; additives; Lithium batteries; Raman; electrolytes; thermal decomposition; NMR spectroscopy;

    Abstract : The state of the art lithium-ion batteries present in most portable electronics consist of the salt LiPF6, organic solvents such as ethylene carbonate and dimethyl carbonate (commonly seen as EC/DMC), and finally, a number of additives - all components enclosed by different kinds of electrode chemistries.Despite their commercial success, all LiPF6 based electrolytes suffer from poor chemical and thermal stability.
