  2. 11. Electrochemical characterisations of TiO2 nanotube and lithium-metal electrodes for lithium-based batteries

    Author : Charlotte Ihrfors; Leif Nyholm; Fredrik Björefors; Marnix Wagemaker; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lithium-ion batteries; titanium dioxide nanotubes; lithium metal electrodes; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Abstract : Lithium-ion batteries have since their introduction on the commercial market in the early 1990s played an important role within the field of energy storage. In this thesis both titanium dioxide, TiO2, and lithium metal are investigated based on their properties as anodes for lithium-based battery technologies. TiO2 nanotubes with lengths between 4.

  4. 12. Adsorption and reactions of sulfur dioxide on TiO2 surfaces : Fundamental studies on single crystals and nanoparticles

    Author : David Langhammer; Lars Österlund; Anders Sandell; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Titanium dioxide (TiO2) is a material that is well-known among researchers in environmental science but is perhaps less well-known by the general public. It is commonly used in white paint because of its ability to scatter visible light, and for this reason it is manufactured at a large industrial scale. READ MORE

  5. 13. Cellular responses to titanium surfaces blasted with TiO2 particles

    Author : Kamal Mustafa; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : A major determinant of successful osseointegration of endosseous implants is the surface topography of the implant, which influences the cellular response of the surrounding tissues. This series of experimental studies investigated cellular responses to surface modifications of titanium implant material. READ MORE

  6. 14. Protein and Cell Interactions with Nanostructured Surfaces

    Author : Emma Westas; Chalmers tekniska högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bacteria; titanium dioxide; implant associated infections; metabolomics; cellular interactions; hydroxyapatite; immune complement activation; silica; nanoparticles; photocatalysis; protein adsorption; Nanostructured implants;

    Abstract : A great challenge of today’s implant development is to construct a surface that promotes tissue integration and avoids bacterial colonization. To avoid implant related infections, many argue that a surface promoting strong cell adhesion and tissue integration in favour for bacterial adhesion would solve the problem, the so-called race for the surface concept.

  7. 15. XDSC : Excitonic Dye Solar Cells

    Author : Eva Unger; Gerrit Boschloo; Tom J. Savenije; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hybrid solar cells; energy transfer; dye-sensitized solar cells; TiO2; small-molecular semiconductor; hole-transporting dye; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

    Abstract : Solar energy is the foremost power source of our planet. Driving photosynthesis on our planet for 3 billion years the energy stored in the form of fossil fuels also originates from the sun. Consumption of fossil fuels to generate energy is accompanied with CO2 emission which affects the earth's climate in a serious manner. READ MORE
