  2. 11. Design of renewable and functional polyamides and polyhydroxyurethanes with tunable structure-property relationships

    Author : Charalampos Pronoitis; Karin Odelius; Minna Hakkarainen; Stefan Naumann; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polyamide; polyhydroxyurethane; polyester; ring-opening aminolysis; ring-opening polymerization; covalent adaptable network; copolymer; complex architecture; polyamid; polyhydroxyuretan; polyester; ringöppningsaminolys; ringöppningspolymerisation; dynamiska nätverk; sampolymer; komplex arkitektur; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Redesigning polymeric materials and rethinking their use is imperative in the prospect of a more sustainable future. Critical aspects in this endeavor are the use of renewable monomers to decrease the environmental footprint, implementing green syntheses and production processes and the design for increased recyclability as an end-of-life option to diverge from the generation of plastic waste.

  4. 12. Sustainable synthetic pathways towards the formation of bio-based polymeric materials

    Author : Susana Torrón; Mats Johansson; Dean Webster; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bio-based; polymers; materials; Kemi; Chemistry;

    Abstract : Increasing environmental and social awareness arising from the use of oil as main source of raw materials, has awaken the interest of many scientists to explore new synthetic pathways for polymer production. These new approaches embrace the use of alternative feedstock and sustainable synthetic routes aiming for enhancing biodegradability and recyclability. READ MORE

  5. 13. Catalytic and Electrocatalytic Transformations with Palladium and Nickel : Scope and mechanistic investigations

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic Chemistry; Heterogeneous Catalysis; Metal-organic frameworks; Nickel; Palladium; Electrocatalysis; Cross-coupling; Hydrogenation; organisk kemi; Organic Chemistry;

    Abstract : The work presented in this thesis is based on methodology development and mechanistic investigations using heterogeneous palladium and nickel catalysts. Following the introduction (Chapter 1), Chapter 2 presents a summary of the synthesis and characterization of the MOF-supported Pd catalysts (Pd @ MOF) that are used in this thesis. READ MORE

  6. 14. Upgrading of fine residual electronic waste by microwave pyrolysis - Material Influence

    Author : Mattias Andersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dielectric properties of waste; recycling; Microwave pyrolysis; WEEE; Waste electrical and electronics equipment;

    Abstract : The large and increasing volumes of waste electrical and electronics equipment (WEEE) in society today make it important to collect and recycle these materials to as high extent as reasonable. Conventional recycling methods are based on mechanical treatments such as shredding, sorting and separation. READ MORE
