  1. 1. Complex Macromolecular Architectures by Atom Transfer Radical Polymerization

    Author : Anna Carlmark; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymer chemistry; controlled radical polymerization;

    Abstract : Controlled radical polymerization has proven to be a viableroute to obtain polymers with narrow polydispersities (PDI's)and controlled molecular weights under simple reactionconditions. It also offers control over the chain-]ends of thesynthesized polymer. READ MORE

  2. 2. Functional Degradable Polymers by a Radical Chemistry approach

    Author : Jenny Undin; Ann-Christine Albertsson; Anna Finne-Wistrand; Jukka Seppälä; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : One class of polymers that is inherently of great value for many applications is the aliphatic polyesters. Such polymers are very suitable for use as temporary guides, scaffolds, for tissue formation and other biomedical applications, due to their biocompatibility, degradability and appropriate mechanical properties.

    Abstract : Lignocellulosic biomass is believed to serve a prominent role in tomorrow’s sustainable energy and material development. Among the polysaccharide fractions of lignocellulosic biomass, the potential of hemicelluloses as a valuable material resource is increasingly recognized. READ MORE

  4. 4. Actor roles, knowledge types and the role of patenting for progressing sustainable technologies: A case study of demonstration projects

    Author : Sofia Nordqvist; Johan Frishammar; Hans Hellsmark; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Entreprenörskap och innovation; Entrepreneurship and Innovation;

    Abstract : The transition towards a bioeconomy is one of the greatest challenges of our times, and dependent upon radical innovations and the replacement of fossil-based technologies with clean and more sustainable ones. This is however not done in a jiffy since key underlying process technologies are underdeveloped and also contradict with the prevailing socio-technical regime. READ MORE

  5. 5. Incumbent Actors in Sectoral Transformations Towards Sustainability : A sociotechnical study of the European heavy commercial vehicles sector

    Author : Benny Behbood Borghei; Thomas Magnusson; Christian Berggren; Sjoerd Bakker; Linköpings universitet; []
