MoRE InnoMat - Miniatursisierung regenerativer Energie durch den Einsatz innovativer Materialsysteme

Dieses Vorhaben wurde aus Mitteln des Europäischen Fonds für regionale Entwicklung (EFRE) gefördert.

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.

Synthesis of Spinel-Type Materials with Tailored Composition and Morphology

The new research project will be funded within the new DFG Transregional Collaborative Research Centre CRC/TRR 247 "Heterogeneous Oxidation Catalysis in the Liquid Phase – Materials and Mechanism in Thermal, Electro- and Photocatalysis". Starting in July 2018, structurally and morphologically well-defined spinel-type cobalt ferrites CoxFe3−xO4 (x = 0–3) will be synthesized and their catalytic properties investigated.

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

The new research project "Verification of a new concept for stabilizing radicals with elements of group 15 and studies concerning their use in one electron transfer reactions" is granted by the DFG. In the next three years, we will investigate the synthesis and reactivity of group 15 metal centered radicals.

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

Our research project "Combined Quantum Chemical and Experimental Study on Metal-Metal Interactions of Heavy Group15 and Group16 Compounds" will by supported for further 3 years by the DFG. We will study the structure-directing role of dispersion interactions with our collaborateur Prof. Dr. G. Jansen, University of Duisburg-Essen.

Our research proposal for a new single crystal X-ray diffractometer is co-funded by the DFG and the state NRW (major instrumentation as per Art. 91b GG).

Recent Publications

We recently established a general synthetic pathway for the generation of Gallastibenes containing Ga=Sb Double Bonds. For further information see DOI: 10.1002/chem.201801813
Together with our cooparation partner Prof C. Jooss (Univ. of Göttingen), we successfully determined the c-axis thermal conductivity for epitaxially-grown Sb2Te3 films. The results were published in J. Appl. Phys. 2018, 123, 175108. Read More
The synthesis and solid state structure of the first neutral gallaarsene containing a Ga=As double bond was published in J. Am. Chem. Soc. and highlighted in Chemistry World.

Awards

Christoph Helling received the prize for the best academic degree (MSc) in chemistry 2017. Well done Christoph!

We congratulate Yannick Schulte for receiving the prize for the best academic degree (BSc) in chemistry 2016. Yannick studied in his bachelor thesis the syntheses and structures of bimetallic β-ketiminate complexes and their catalytic activities in ring-opening polymerization (ROP) of lactide.

We congratulate Christoph Helling for receiving the prize for the best academic degree (BSc) in chemistry 2015. Christoph investigated in his Bachelor thesis reduction reactions of group 15 metal complexes with group 13 diyl specises such as ddpGa.

The researchteam (Oliver Ochedowski, Experimental physics; Steven Gottlieb, BA-Student Nano-Engineering; Kosuke Shibasaki, University of Tsubaka, Japan; Stephan Schulz, Inorganic Chemistry; Volker Buck, Technical Chemistry) lead by Dr. Nicolas Wöhrl has won the this year's "CENIDE Cooperative Research Award".

The jury dignified the fascinating work to PECVD-Deposition of graphene on metalsubstrates with 2.000,- €. We are glad about this award.
