  1. 1. Thermoelectric properties of conducting polymers

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

    Abstract : 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. READ MORE

  2. 2. Conjugated Polymers for Neural Interfaces : Prospects, possibilities and future challenges

    Author : Maria Asplund; Hans von Holst; Olle Inganäs; Thomas Stieglitz; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; MEDICIN OCH HÄLSOVETENSKAP; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; MEDICAL AND HEALTH SCIENCES; neuroprosthetics; conjugated polymers; conducting polymers; PEDOT; functional electrical stimulation; neural electrodes; Medical engineering; Medicinsk teknik; Neuroscience; Neurovetenskap; Functional materials; Funktionella material;

    Abstract : Within the field of neuroprosthetics the possibility to use implanted electrodes for communication with the nervous system is explored. Much effort is put into the material aspects of the electrode implant to increase charge injection capacity, suppress foreign body response and build micro sized electrode arrays allowing close contact with neurons.

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

    Author : Johan Hjelm; Anders Hagfeldt; Emad Mukhtar; Robert Forster; A. R. Hillman; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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;

    Abstract : 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.

  4. 4. Thermoelectric Devices with Electronic and Ionic Conducting Polymers

    Author : Zia Ullah; Xavier Crispin; Magnus Berggren; Marisol Martin-Gonzalez; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Thermoelectricity; conducting polymers; thermoelectric devices;

    Abstract : The energy consumption in the world is continuously growing and the sources of energy are largely dominated by fossil fuels. However, the resources of oil, gas and coal are diminishing in capacity. Moreover the CO2 emissions arising from their combustion is a great concern because it induces climate changes that threaten our habitat. READ MORE

  5. 5. Functional composite coatings containing conducting polymers

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

    Abstract : 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. READ MORE
