  1. 16. Scandium Nitride Thin Films for Thermoelectrics

    Author : Sit Kerdsongpanya; Per Eklund; Björn Alling; Lars Hultman; Gunilla Wingqvist; Heiner Linke; Linköpings universitet; []
    Keywords : ;

    Abstract : Thermoelectric devices are one of the promising energy harvesting technologies, since they can convert heat (i.e. a temperature gradient) to electricity. This result leads us to use them to harvest waste heat from heat engines or in power plants to generate usable electricity. READ MORE

  2. 17. Through-Drying of Tissue Paper - Experiments and Modelling

    Author : Henrik Weineisen; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paper drying; modelling; TAD; through-drying; through-air drying; tissue; paper;

    Abstract : In through-drying of paper, the energy required for drying is supplied by hot air, which is forced through the paper structure. The area for heat and mass transfer is the internal surface area of the paper, which is often many times larger than the external web surface area (xy-plane). READ MORE

  3. 18. Battery thermal management for electric vehicles operating in cold climates

    Author : Anandh Ramesh Babu; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; battery pack encapsulation; electric vehicle; battery modeling; lithium-ion battery; low-temperature performance;

    Abstract : Electromobility has gained significance over recent years in an attempt to reduce greenhouse gas emissions which contribute to climate change. The requirements on the performance and efficiency of electric vehicles are high to make them an attractive alternative to the conventional fossil-fuel driven vehicles. READ MORE

  4. 19. Economic and Environmental Benefits of CHP-based District Heating Systems in Sweden

    Author : Shahnaz Amiri; Björn G. Karlsson; Louise Trygg; Mats Westermark; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Future energy systems and thus the climate are affected by many factors, such as energy resources, energy demand, energy policy and the choice of energy technologies. Energy systems of the future are facing three main challenges; the steady growth of global energy demand, the energy resource depletion, as well as the increasing emissions of carbon dioxide (CO2) and other greenhouse gases and their impact on climate change.

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

    Author : Mohsen Yakhshi Tafti; Muhammet S. Toprak; Gao Min; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thermoelectric; Iron antimonide FeSb2 Skutterudite; Copper Selenide Cu2Se ; Spark Plasma Sintering SPS ; nanomaterial; Teknisk materialvetenskap; Materials Science and Engineering; Energy Technology; Energiteknik;

    Abstract : 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. READ MORE
