Department of Chemistry and Interdisciplinary Nanoscience Centre (iNANO)

The University of Aarhus (http://www.au.dk) has in total 30.00 students and ca. 1800 people employed as Academic staff. The Faculty of Science consists of 9 departments and 29 research centres and one of those is The Interdisciplinary Nanoscience Centre (iNANO). iNANO has 60 senior researchers, 45 post docs and 120 PhD students associated. An important research field is represented by The Centre for Energy Materials (CEM) which has the scientific core: design, preparation, characterisation and application of novel materials for energy production, energy conversion, energy storage and improved energy efficiency. FLYHY will be associated with CEM and iNANO, which offers a very strong research network and also a high quality graduate school, iNANOschool. iNANO has played an active part in a previous Danish national interdisciplinary project on the ‘hydrogen society’ and has >20 years of research experience within the interaction of hydrogen with metals.

In FLYHY AU will focus on materials preparation, in particular the combined us of ‘wet chemistry’ and mechanical alloying. AU will also contribute to structural characterisation and detailed investigation of the mechanism for hydrogen release and uptake by in situ synchrotron radiation powder X-ray diffraction. AU has good access to the synchrotron facility MAX-lab in Lund Sweeden, e.g. 20 days of beam time per year.

Scientists involved in FLYHY:

Assoc. Prof. Dr. Torben Rene Jensen is an expert in synthetic materials and inorganic chemistry and characterisation of gas/solid reactions by in situ PXD. He received his PhD in 1999 at SDU, Odense. As a visiting scientist he was at various synchrotron radiation facilities, e.g. NSLS, Brookhaven National Laboratory, USA and Hasylab at DESY in Hamburg. Since 2000 he was Assistant Prof., since 2002 Associate Prof. at Aarhus Universitet and in 2006 appointed 'Scientific expert' for the IEA HIA, Task 22 (Hydrogen storage materials). Among others he is a member of the steering committee of „The Danish Hydrogen Link project“, leader of the research program ‘novel gas storage materials’ in CEM and member of the Danish Hydrogen Association (DHA). He has authored >55 articles in international peer-reviewed journals. Director, Prof. Hans J. Jakobsen and Assoc. Prof., Jørgen Skibsted from the Danish Instrument Center for Solid State NMR Spectroscopy, University of Aarhus (AU) have a long track record within solid state MAS NMR, have received several awards and have authored 253 and 82 scientific papers, respectively. They have also initiated an investigation of hydrogen storage materials.

Experimental facilities:

Schlenck equipment, equipment for wet chemistry synthesis, autoclaves, ovens for heating in selected gas atmosphere, high frequency furnace for metal alloy synthesis, high energy ball mill, reactive milling, Sievert’s apparatus, thermal analysis (DSC, TGA/DTA), several powder and single crystal X-ray diffractometers, equipment implemented at the synchrotron facility MAX-lab, several NMR spectrometers dedicated for solid state MAS NMR, also at variable temperatures (in collaboration with Prof. H. J. Jakobsen and Assoc. Prof. J. Skibsted).
