  1. 1. Conducting Foams and Fibres for Bulk Plastic Thermoelectrics

    Författare :Jason Ryan; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; nanocomposites.; e-textiles; renewable energy; conducting yarn; thermoelectrics; conjugated polymers; organic thermoelectrics; electronic textiles; polymer foams; conducting fibres;

    Sammanfattning : The use of small portable electronics in society is constantly increasing, thus the demand for portable power sources also rises in turn. Portable electronic devices rely upon energy stored in batteries to power them, which in turn require regular access to power outlets to be recharged. LÄS MER

  2. 2. Nanostructured Bulk Thermoelectrics : Scalable Fabrication Routes, Processing and Evaluation

    Författare :Mohsen Yakhshi Tafti; Muhammet S. Toprak; Gao Min; KTH; []

    Sammanfattning : Current fossil fuel based energy sources have a huge shortcoming when one discusses their efficiency. The conversion efficiency of fossil fuel-based technologies is less than 40% in best cases. LÄS MER

  3. 3. Design of Thermoelectric Generators for Automotive EGR Applications

    Författare :Olle Högblom; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Contact resistances; Exhaust gas heat recovery; Thermoelectrics; CFD;

    Sammanfattning : Rising energy prices and greater environmental awareness along with stringent emissions legislation in the automotive industry make it possible to introduce techniques in the aftertreatment system that have previously been unprofitable. One such technique, studied in this work, is heat recovery in the exhaust gas recirculation (EGR) cooler using thermoelectric generators (TEG). LÄS MER
