  1. 16. Conducting Polymer Electrodes for Oxygen Reduction Reaction

    Författare :Evangelia Mitraka; Xavier Crispin; Magnus Berggren; Magnus Jonsson; Mikhail Vagin; Björn Winther-Jensen; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Both the pollution level of the environment and the increasing energy demands have stimulated intense research on the development of low-cost environmentally-friendly energy conversion and storage systems with high efficiency, such as metal-air batteries and fuel cells.One of the most essential parts of both fuel cells and metal–air batteries is the air-electrode which is responsible for the reduction of O2.

  3. 17. Structural Composite Lithium-Ion Battery : Effect of Intercalation induced volumetric changes on micro-damage

    Författare :Johanna Xu; Janis Varna; Andrejs Pupurs; Göran Lindbergh; Kenneth Runesson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera kompositmaterial; Polymeric Composite Materials;

    Sammanfattning : The quest for lighter materials and structures to reduce climate impacts in the automotive industry has paved the way for multifunctional solutions. Mass saving on a system level can be achieved by materials or structures having more than one primary function, thus reducing the number of components used. LÄS MER

  4. 18. Investigation of microstructure and porosity of columnar yttria-stabilized zirconia coatings produced by axial suspension plasma spraying

    Författare :Johanna Ekberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; X-ray microscopy; thermal barrier coatings; NMR cryoporometry; suspension plasma spraying; scanning electron microscopy; porosity measurements;

    Sammanfattning : Ceramic topcoats provide thermal barrier coatings (TBCs) with its heat insulating properties. The heat transfer is primarily occurring by conduction through the bulk material, therefore features such as interfaces, pores and grain boundaries are essential for thermal insulation as they act as scattering sites.

  5. 19. All-Thin-Film Electrochromic Devices for Optical and Thermal Modulation

    Författare :Anna-Lena Larsson; Gunnar A Niklasson; Lars Stenmark; Michael G Hutchins; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; Teknisk fysik; Engineering physics; Teknisk fysik;

    Sammanfattning : The optical properties of electrochromic materials can be changed by application of an electrical voltage. The conventional electrochromic device consists of several thin films of electrochromic materials and layers for electron- and ion conduction. LÄS MER

  7. 20. Molecular Modeling of Cardiolipin

    Författare :Martin Dahlberg; Arnold Maliniak; Richard W. Pastor; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi; fysikalisk kemi; Physical Chemistry;

    Sammanfattning : Biological membranes are assembled from many different lipids. Our understanding of membrane function and morphology is dependent on linking the properties of the lipids to the properties of the membranes. LÄS MER
