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

    Författare :Jason Ryan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 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

  3. 2. Thermoelectric properties of conducting polymers

    Författare :Olga Bubnova; Xavier Crispin; Magnus Berggren; Alan Kaiser; Linköpings universitet; []
    Nyckelord :Thermoelectric generation; Seebeck coefficient; conducting polymers; thermoelectric efficiency.;

    Sammanfattning : According to different sources, from forty to sixty percent of the overall energy generated in the world today is squandered in waste heat. The existing energy conversion technologies are either close to their efficiency limits or too costly to justify their implementation. LÄS MER

  4. 3. Dual-ion Conducting Nanocompoiste for Low Temperature Solid Oxide Fuel Cell

    Författare :Xiaodi Wang; Mamoun Muhammed; Zhu Bin; Peter Lund; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel cell; Nano; Composite; Conducting; Electrolyte; SRA - Energy; SRA - Energi;

    Sammanfattning : Solid oxide fuel cells (SOFCs) are considered as one of the most promising power generation technologies due to their high energy conversion efficiency, fuel flexibility and reduced pollution. There is a broad interest in reducing the operating temperature of SOFCs. LÄS MER

  5. 4. Functional composite coatings containing conducting polymers

    Författare :Shadi Jafarzadeh; Per Martin Claesson; Arjan Mol; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Conducting polymer; Polyaniline; Conductive network; Nanocomposite; Active corrosion protection; Interfacial energy; UV curing; Kemi; Chemistry;

    Sammanfattning : Organic coatings are widely used to lower the corrosion rate of metallic structures. However, penetration of water, oxygen and corrosive ions through pores present in the coating results in corrosion initiation and propagation once these species reach the metal substrate. LÄS MER

  7. 5. Conducting Polymers Containing In-Chain Metal Centres : Electropolymerisation and Charge Transport

    Författare :Johan Hjelm; Anders Hagfeldt; Emad Mukhtar; Robert Forster; A. R. Hillman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Polymer electrochemistry; Conducting Polymers; Metal Complexes; Electropolymerization; Electron-hopping; Microelectrodes; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : Conjugated polymers that exhibit high electronic conductivities play key roles in the emerging field of molecular electronics. In particular, linking metal centres with useful electrochemical, photophysical, or catalytic properties to the backbone, or within the polymer chain itself, is a topic which has attracted a significant amount of interest lately.
