  1. 21. Stability of Bulk-heterojunction blends for Solar Cell Applications

    Författare :Camilla Lindqvist; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanostructure; PCBM crystallisation; bulk-heterojunction; Polymer solar cells; stability;

    Sammanfattning : Polymer solar cells are a promising alternative to more traditional silicon solar cells. This is mainly due to the good solubility of organic semiconductors, which makes it possible to produce large-scale and mechanically flexible devices with roll-to-roll processes. LÄS MER

  3. 22. Mass Stabilization, Stability and Settlement in Mass Stabilized Peat

    Författare :Nenad Jelisic; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mass stabilization; stabilizer; field investigations; laboratory investigations; settlement; stability; peat; Building construction; Byggnadsteknik;

    Sammanfattning : Peat is badly suited as a base for road and railway embankments due to its geotechnical properties. The usual procedure has been, therefore, to excavate peat and replace it with blasted rock. LÄS MER

  4. 23. By Means of Beams : Laser Patterning and Stability in CIGS Thin Film Photovoltaics

    Författare :Per-Oskar Westin; Marika Edoff; Uwe Zimmermann; Lars Stolt; Friedrich Kessler; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser patterning; laser ablation; laser micro-welding; stability; Cu InGa Se2; CIGS; thin film solar cells; thin film photovoltaics; module technology; solar energy; Electronics; Elektronik; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Sammanfattning : Solar irradiation is a vast and plentiful source of energy. The use of photovoltaic (PV) devices to convert solar energy directly to electrical energy is an elegant way of sustainable power generation which can be distributed or in large PV plants based on the need. LÄS MER

  5. 24. Black liquor gasification : experimental stability studies of smelt components and refractory lining

    Författare :Mathias Råberg; Dan Boström; Anders Nordin; Honghi Tran; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; black liquor gasification; DTA; stability; thermal analysis; thermochemical data; HTM; HT-XRD; metastable; phase diagram; refractory lining; SEM; Chemical energy engineering; Kemisk energiteknik;

    Sammanfattning : Black liquors are presently combusted in recovery boilers where the inorganic cooking chemicals are recovered and the energy in the organic material is converted to steam and electricity. A new technology, developed by Chemrec AB, is black liquor gasification (BLG). LÄS MER

  7. 25. Form and Finish of Implants in Uncemented Hip Arthroplasty : Effects of Different Shapes and Surface Treatments on Implant Stability

    Författare :Stergios Lazarinis; Nils P. Hailer; Lars Weidenhielm; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Form; Finish; Total hip arthroplasty; Swedish Hip Arthroplasty Register; Hydroxyapatite; RSA; DXA; BMD; Stability.; Orthopaedics; Ortopedi;

    Sammanfattning : The design of an uncemented hip arthroplasty implant affects its long-term survival. Characteristics such as the form and the finish of the implant are crucial in order to achieve the best possible conditions for long-term implant survival. LÄS MER
