    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tin; Tin oxide; Lithium-ion batteries; Electrochemistry; High temperature cycling; Conversion reaction; XPS; SEM; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : This thesis aims to provide insight into the fundamental electrochemical processes taking place when cycling SnO2 in lithium-ion batteries (LIBs). Special attention was paid to the partial reversibility of the tin oxide conversion reaction and how to enhance its reversibility. LÄS MER

  5. 4. Towards Conduction Band Mediated Multi-electron Transfer: Spectroscopic Studies of Photosensitizer-semiconductor-acceptor Assemblies

    Författare :Elin Sundin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Solar fuels; charge separation; dye-sensitized; semiconductor thin films; electron transfer;

    Sammanfattning : Converting solar energy into a storable form in chemical bonds, i.e., generating solar fuels, is a promising strategy for producing renewable fuels. This however comes with several challenges that need to be solved before generation of solar fuels can become a reality. LÄS MER

  7. 5. Characterization of interfaces by elastic light scattering and profilometry

    Författare :Tomas Lindström; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Sammanfattning : This thesis deals with the characterization of interfaces by elastic light scattering and profilometry. The sensitivity of scattering measurements to surface topography were used in two major ways. It was shown that surface reactions in a liquid-solid interface can be monitored in situ in terms of changes in surface roughness. LÄS MER
