NRW-Leitmarktwettbewerb (OP EFRE NRW)


​Title: "MoRE InnoMat - Miniatursisierung regenerativer Energie durch den Einsatz innovativer Materialsysteme" -  Dieses Vorhaben wurde aus Mitteln des Europäischen Fonds für regionale Entwicklung (EFRE) gefördert.

Collaborateur: University of Duisburg-Essen, Zentrum für Brennstoffzellentechnik ZBT, Neoxid GmbH, Iplas GmbH

Goal: MikrobrennstoffzelleBrenstoffzellen stellen eine Schlüsseltechnologie bei der Nutzung regenaerativer Energien dar. Dabei werden zunehmend auch Anwendungen im kleinen und kleinsten Leistungsbereich interessant, insbesondere bei der Energieversorgung portabler Elektronikgeräte, denn Brennstoffzellen weisen im Vergleich zu Lithium-Ionen Akkumulatoren eine höhere Leistungsdichte auf.

Title: "Synthesis of Spinel-Type Materials with Tailored Composition and Morphology"

Goal: Structurally and morphologically well-defined spinel-type cobalt ferrites CoxFe3−xO4 (x = 0–3) will be synthesized by thermal decomposition of molecular precursors in organic solvents. The chemical composition will be systematically varied and the nanoparticle size and shape and, as a consequence, their real surface and defect structure, will be precisely adjusted.

Title: "Verification of a new concept for stabilizing radicals with elements of group 15 and studies concerning their use in one electron transfer reactions"

Goal: The stabilization of reactive group 15 element radicals by coordination of an electropositive metal fragment L(X)M (M = Al - In) will be studied. Reaction mechanism will be studied by in situ 1H-NMR spectroscopy and the structure of the radicals will be characterized by EPR, single crystal X-ray diffraction and quantum chemical calculations. In addition, electrochemical studies (SET) as well as single electron transfer (SET) and small molecule activation reactions will be investigated.

Title: "Low-temperature Synthesis of Thermoelectric Materials by Thermal Decomposition of Tailor-made Metal Organic Precursors in Ionic Liquids"

Collaborateur: Dr. G. Schierning, IWF Dresden

Goal: New synthetic routes to improved thermoelectric V2VI3 materials will be developed by treatment of specific metal organic precursors in ionic liquids by microwave irradiation. The most important thermoelectric properties such as Seebeck coefficient, power factor as well as thermal and electrical conductivity will be determined by state-of-the-art techniques.

Title: "Combined Quantum Chemical and Experimental Study on Metal-Metal Interactions of Heavy Group15 and Group16 Compounds"

Collaborateur: Prof. Dr. G. Jansen, University of Duisburg-Essen

Goal: The suitability of organometallic compounds containing the heaviest elements of groups 15 (Sb, Bi) and 16 (Se, Te) for the generation of high-density dispersion energy donors (DEDs) will be investigated by using an intertwined experimental and theoretical strategy, combining quantum chemical prediction, synthesis, and X-ray structural analysis of interacting moieties.

Title: "Epitaxial MOCVD deposition of thermoelectric material films and determination of thermoelectric properties including thermal conductivity"

Collaborateur: Prof. C. Jooß, University of Göttingen

Goal: The goal of this project is the MOCVD deposition of epitaxial films of thermoelectric materials for technical application in the low (<350 °C) and medium (400 - 700 °C)) temperature range using tailor-made metal organic group 15 and 16 precursors and the determination of their transport properties.

Title: "Reduction reaction of main group element complexes of group 13 and 15 with selected molecular one-electron and two-electron reductants"

Goal: Systematic investigations on the reduction reaction of heavy main group element compounds of group 13 and 15 elements, which adopt different formal oxidation state numbers and carry different substituents with different metal-X bond strengths, with soluble metal organic one-electron and two-electron reductants will be performed in order to investigate the role of the reduction potentials of the reductants as well as the role of the formal oxidations state of the metal atom and the E-X bond strength (X = C, N, H, Si) on the outcome of the reactions and the resulting (intermetalloid) compounds. Quantum chemical calculations will be performed in collaboration with Prof. G. Jansen in order to investigate the electronic structure of the resulting compounds.
