  1. 1. The role of liquid resin in orthodontic bonding : toxicological, bond strength and clinical aspects

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Odontology

    Författare :Alexander Tin Hong Tang; Karolinska Institutet.; Karolinska Institutet.; [2000]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cytotoxicity; dental acrylic resins; enamel adhesion; orthodontic bonding;

    Sammanfattning : Dental acrylic composites are rarely fully polymerized in situ. Their unpolymerized components are related to undesirable occupational exposure to dental, particularly orthodontic, personnel. LÄS MER

  2. 2. Fundamental Insights into the Electrochemistry of Tin Oxide in Lithium-Ion Batteries

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Solveig Böhme; Uppsala universitet.; [2017]
    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

  3. 3. High-resolution characterization of TiN diffusion barrier layers

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Marlene Mühlbacher; Linköpings universitet.; Linköpings universitet.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diffusion; TiN; Microstructure; Transmission electron microscopy; TEM; Atom probe tomography; APT;

    Sammanfattning : Titanium nitride (TiN) films are widely applied as diffusion barrier layers in microelectronic devices. The continued miniaturization of such devices not only poses new challenges to material systems design, but also puts high demands on characterization techniques. LÄS MER

  4. 4. Tin whiskers: experiments and modelling

    Detta är en avhandling från Department of Construction Sciences, Lund University

    Författare :Johan Hektor; Lunds universitet.; Lund University.; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tin whiskers; Intermetallics; Phase field models; X-Ray Diffraction;

    Sammanfattning : Tin whiskers are hair-like single crystals that spontaneously grow from tin-coated surfaces. Whiskers are commonly found in electronic components, where tin coatings are used in, e.g., soldering applications, and to protect components from corrosion. LÄS MER
