  1. 21. Film morphology for organic solar cells : Effect of Solubility and Gravity Conditions

    Författare :Ishita Jalan; Jan van Stam; Leif Ericsson; Stela Andrea Muntean; Philippe Leclère; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; Chemistry - Physical Chemistry; Kemi - fysikalisk kemi;

    Sammanfattning : Organic photovoltaics is a promising environmentally friendly technology, due to their printability, light-weight nature and mechanical flexibility, and the possibility to use off-grid. Research and development in this field has resulted in power conversion efficiencies of over 15%. LÄS MER

  3. 22. Corrosion of Ferritic Stainless Steels Used in Solid Oxide Fuel Cells

    Författare :Claudia Goebel; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SOFC; Corrosion; Dual Atmosphere; Interconnect; Area Specific Resistance;

    Sammanfattning : Solid oxide fuel cells (SOFC) are energy conversion systems with clean emissions (depending on the fuel used) and high electrical efficiencies, which could potentially replace conventional conversion systems such as combustion engines. However, other issues, such as high costs and limited lifetime, must be resolved before widespread commercialization of SOFCs can be achieved. LÄS MER

  4. 23. Characteristic Properties and Applications of Fine Particles in Biomass Gasification

    Författare :Azhar Malik; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gasification; Biomass; Fine particles; catalyst deactivation; dilution probe sampling; organic;

    Sammanfattning : The gasification of biomass is a promising route to increase the share of renewable sources in the energy mix. Besides having an overall higher thermal efficiency than combustion, it also offers the possibility of producing gaseous and liquid biofuels that can be used in the transport sector. LÄS MER

  5. 24. CVD on Iron Powder - Using Fluidising Bed Techniques

    Författare :Lars Nilsson; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aluminium oxide; alumina; chemical vapour deposition; eddy current losses; FBR; iron; fluidising bed reactor; powder; SiO2; SMC; TiO2; Al2O3; soft ma etic com sites; CVD;

    Sammanfattning : Today's electrical energy conversion devices, such as motors, transformers, inductors and generators, are based on laminated magnetic cores for reduction of eddy current losses, imposing a two-dimensional magnetic flux distribution. Using a three-dimensional magnetic flux distribution while maintaining low magnetic losses requires new approaches to magnetic core materials. LÄS MER

  7. 25. Development of Functionalized Protein Materials

    Författare :Yusheng Yuan; Niclas Solin; Olle Inganäs; Qi Zhou; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Many proteins are available as side-streams from food production, and in some cases even from industrial waste-streams. This means that proteins are available in large scale and at a relatively low price. As protein are highly complex molecules it is interesting to try to use protein as starting materials in for applications in materials science. LÄS MER
