  4. 2. Tin whiskers: experiments and modelling

    Author : Johan Hektor; Hållfasthetslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tin whiskers; Intermetallics; Phase field models; X-Ray Diffraction;

    Abstract : 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. READ MORE

  5. 3. Design and Characterisation of new Anode Materials for Lithium-Ion Batteries

    Author : Linda Fransson; Anthony West; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; in situ X-ray diffraction; graphite; Li-ion battery; anode materials; intermetallics; structure-property relationships; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

    Abstract : Reliable ways of storing energy are crucial to support our modern way of life; lithium-ion batteries provide an attractive solution. The constant demand for higher energy density, thinner, lighter and even more mechanically flexible batteries has motivated research into new battery materials. Some of these will be explored in this thesis. READ MORE

  6. 4. Functional materials studies by Mössbauer spectroscopy

    Author : Erik Nordström; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; fysik; Physics;

    Abstract : Mössbauer spectroscopy has been used as a powerful tool to investigate the local properties of some materials suitable as active ingredients in technological applications. The magnetic properties of some magnetic multilayers were investigated using conversion electron Mössbauer spectroscopy. READ MORE

  7. 5. Reliability, fatigue and mechanical characterization of lead-free solders for electronic packaging applications

    Author : Cristina Andersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reliability.; Isothermal mechanical fatigue; Tensile tests; Mechanical behavior; Electronics; Thermal fatigue; Lead-free solders; Low cycle fatigue;

    Abstract : The ever increasing amount of electronic waste, most of which ends up in landfills, has become a serious worldwide concern. In addition to this, the fact that Pb is highly toxic and harmful to humans has lead to the ban of this element from the electronics industry. READ MORE
