Investigation of the redox transformations of conducting polymers via in situ,  simultaneous combined techniques . Our research group developed in situ combined techniques (spectroelectrochemistry,  electrochemical quartz crystal nanobalance, conductivity measurement) to monitor redox alterations  in conducting polymers. Most recently a novel hyphenated combined in situ method was  established, which involves the parallel monitoring of UV-Vis spectra and electrical conductivity. For  these complex experiments special electrodes are needed, therefore a novel cell-configurations  were also developed. Synthesis and characterization of ferrit-containing conducting polymer nanocomposites   Synthesis and characterization of conducting polymer composites containing magnetic  nanoparticles attract increasing attention, nowadays. Magnetic nanoparticles (e.g. Fe2O3, Fe3O4,  CoFe2O4, Ni, Fe, metal alloys) with typical size of 1-30 nm usually exhibit superparamagnetic  features, but rarely ferri- or ferromagnetic properties can also be observed. Incorporation of these  nanoparticles results in hybrid materials which can be used in many different fields, e.g., magnetic  separation, microwave shielding, catalysis, and sensors. Photoactive hybrid organic/inorganic assemblies based on conducting polymers  Hybrid materials based on conducting polymers (CPs) and inorganic semiconductors (SCs)  undoubtedly constitute one of the most promising classes of new materials. Beyond scientific and  fundamental interest, such hybrid assemblies are attractive from technological perspectives as well,  for example, in energy conversion & storage, electronics, catalysis, and optics. CPs can be  employed both as sensitizers and hole-transporters in such applications. In this vein we assemble  organized nanoarchitectures of CPs and oxide SCs. Conducting polymer-based hybrid materials with thermoelectric properties  Conducting polymers have prominently large Seebeck-coefficient - some cases it can even exceed  1mV/K, which is five times larger than that of bismuth telluride (Bi2Te3), the most frequently used  inorganic thermoelectric material. This fact makes CPs attractive candidates for fabricating new  generation lightweight and flexible thermoelectric materials. In addition, polymers generally have  low thermal conductivity () which is also an important factor in the high thermoelectric figure of  merit.
