HZB part of new metal oxide/water systems CRC
A team of HZB researchers is part of the new collaborative research center, "Molecular insights into metal oxide/water systems" funded by the German Research Association. As part of this CRC, Dr. Bernd Winter of Prof. Dr. Emad Aziz's junior research group will be studying metal ions and metal oxide complexes in aqueous solution at BESSY II.
Spokesman of the CRC is Prof. Dr. Christian Limberg of the Humboldt University Berlin. Other partners include the Freie Universität Berlin, the Technical University of Berlin, Potsdam University, the Federal Institute for Materials Research and Testing Berlin, and the Fritz Haber Institute of the Max Planck Society Berlin.
The researchers are using a liquid microjet under vacuum conditions allowing them to obtain measurements of aqueous solutions using photoelectron spectroscopy at BESSY II. Their measurements allow for conclusions to be drawn on the binding energies and on electronic relaxation processes and thus provide clues as to the interaction between metal oxide complexes and the surrounding water molecules. In addition, the technique can be used to determine precursor molecules that will go on to form larger metal-oxo networks.
These insights are key to our ability to synthesize metal oxides for specific applications, which is typically done in aqueous solution. The reason being that metal oxides are highly interesting in terms of their technological applicability: they upgrade building materials and special types of glass, improve the properties of ceramic implants in medicine, and are considered interesting candidates for use in fuel cells, solar cells, microelectronics, and as novel kinds of catalysts.
Spokesman of the CRC "Molecular insights into metal oxide/water systems: Structural evolution, interface, and resolution" is Prof. Dr. Christian Limberg of the Humboldt University Berlin. Other partners include the Freie Universität Berlin, the Technical University of Berlin, Potsdam University, the Federal Institute for Materials Research and Testing Berlin, and the Fritz Haber Institute of the Max Planck Society Berlin. Together, the participating research groups are hoping to investigate different fundamental processes relating to metal oxide interactions with water on all relevant length scales using a combination of chemical synthesis and cutting-edge experimental and theoretical methods. In late November 2013, the German Research Association established nine new collaborative research centers (CRC's), which, through mid-2017, will receive federal funding in the amount of 64.4 million Euros total.
- Green hydrogen: MXenes shows talent as catalyst for oxygen evolutionThe MXene class of materials has many talents. An international team led by HZB chemist Michelle Browne has now demonstrated that MXenes, properly functionalised, are excellent catalysts for the oxygen evolution reaction in electrolytic water splitting. They are more stable and efficient than the best metal oxide catalysts currently available. The team is now extensively characterising these MXene catalysts for water splitting at the Berlin X-ray source BESSY II and Soleil Synchrotron in France.
- Review on ocular particle therapy (OPT) by international expertsA team of leading experts in medical physics, physics and radiotherapy, including HZB physicist Prof. Andrea Denker and Charité medical physicist Dr Jens Heufelder, has published a review article on ocular particle therapy. The article appeared in the Red Journal, one of the most prestigious journals in the field. It outlines the special features of this form of eye therapy, explains the state of the art and current research priorities, provides recommendations for the delivery of radiotherapy and gives an outlook on future developments.
- "BESSY is of immense importance for Berlin"At the end of August, the Senator for Research, Health, and Long-Term Care, Dr Ina Czyborra, together with the State Secretary for Science, Dr Henry Marx, ended her summer tour with a visit to HZB in Adlershof. She publicly declared her political support for the new construction of BESSY III.
