  2. 1. Global energy transitions : Renewable energy technology and non-renewable resources

    Author : Simon Davidsson; Mikael Höök; Kjell Aleklett; Björn Sandén; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy transitions; natural resources; renewable energy; sustainable development; growth curves; Natural Resources and Sustainable Development; Naturresurser och hållbar utveckling;

    Abstract : The global energy system is dominated by the use of fossil fuels. This system suffers from several problems, such as different environmental issues, while the long-term energy security is sometimes questioned. READ MORE

  4. 2. Thiol−ene Coupling of Renewable Monomers : at the forefront of bio-based polymeric materials

    Author : Mauro Claudino; Mats K. G. Johansson; Mats Jonsson; Anna Wistrand; Sven Göthe; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thiol-ene chemistry; monounsaturated fatty-acids; renewable resources; cis trans-isomerization; photopolymerization; networks; polyesters; thermal viscoelastic properties; thin-films; unsaturated macro lactones; coatings;

    Abstract : Plant derived oils bear intrinsic double-bond functionality that can be utilized directly for the thiol–ene reaction. Although terminal unsaturations are far more reactive than internal ones, studies on the reversible addition of thiyl radicals to 1,2-disubstituted alkenes show that this is an important reaction.

  5. 3. Exploring fatty acid derivatives from renewable resources as raw materials for coating applications

    Author : Samer Nameer; Mats Johansson; Mats Martinelle; Dean Webster; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; epoxy; vegetable oils; birch bark; thermoset; bio-based; fatty acid; renewable resources; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : In the work presented herein, epoxy fatty acid derivatives were explored in the formation of thermosets for coating applications. The epoxy fatty acid derivatives were obtained from renewable resources such as birch tree bark and epoxidized linseed oil. READ MORE

  6. 4. Renewable Composites Prepared from Biobased Thermoset Resins

    Author : Dan Åkesson; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Renewable; natural fibre; composite; biobased thermoset resin;

    Abstract : In our efforts to create a more sustainable society, several researchers have tried to prepare composites from renewable materials in recent years. The use of natural fibres for reinforcement of composites has been relatively well studied. READ MORE

  7. 5. Functional PVC Additives : Core-Shell Nanoparticle and Renewable Resource Plasticizers

    Author : Bo Yin; Minna Hakkarainen; Mikael Skrifvars; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PVC; nanocomposite; nanoparticle; core-shell; plasticizer; renewable resources; isosorbide; glucose;

    Abstract : Several functional poly(vinyl chloride) (PVC) additives were designed: PVC plasticizers made from renewable resources as alternatives to traditional phthalate plasticizers and core-shell nanoparticle-plasticizers with the aim to design an additive that can improve several mechanical properties simultaneously. Monomeric and oligomeric PVC plasticizers based of isosorbide and glucose were synthesized. READ MORE
