  2. 16. Macromolecular synthesis of functional degradable aliphatic polyesters and porous scaffold design

    Author : Sofia Målberg; Ann-Christine Albertsson; Anders Södergård; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; functional polyesters; condensation polymerization; L-lactide; ε-caprolactone; triblock copolymer; mechanical properties; porous scaffolds; tissue engineering; ring-opening polymerization; Bi III acetate; creatinine; stannous 2-ethylhexanoate; enzyme; degradation products; Polymer chemistry; Polymerkemi;

    Abstract : There is an increasing demand for new materials in biomedical applications with material properties that are highly specific for each application area. The search for new materials requires the creation of materials with suitable mechanical properties, functionalities, three-dimensional structures and a controlled degradation profile. READ MORE

  4. 17. Electrochromic Nickel – Tungsten Oxides : Optical, Electrochemical and Structural Characterization of Sputter-deposited Thin Films in the Whole Composition Range

    Author : Sara Green; Gunnar Niklasson; Claes-Göran Granqvist; Esteban Avendaño; Aline Rougier; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrochromism; Nickel oxide; Tungsten oxide; Lithium intercalation; Sputtering; Thin films; Nanostructures; Optical properties; Solid State Physics; Fasta tillståndets fysik;

    Abstract : This thesis investigates the electrochromic NixW1-x oxide thin film system, where 0 < x < 1. The thin films were deposited by reactive DC magnetron co-sputtering from one Ni and one W metal target. In addition, Ni oxide was deposited with water vapor added to the sputtering gas. READ MORE

  5. 18. Electrochemical and ion transport characterisation of a nanoporous carbon derived from SiC

    Author : Marcelo Zuleta; Pehr Björnbom; Derek Pletcher; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; Cottrell equation; radial diffusion; chronoamperometry; potential step measurements; microelectrode technique; nanoporous carbon; Kemiteknik; Chemical engineering; Kemiteknik;

    Abstract : In this doctoral project, a relatively new form of carbon material, with unique narrow pore size distribution around 7 Å and with uniform structure, has been electrochemically characterised using the single particle microelectrode technique. The carbon has been used as electrode material for supercapacitors. READ MORE

  6. 19. Proton-Conducting Sulfonated and Phosphonated Polymers and Fuel Cell Membranes by Chemical Modification of Polysulfones
