The Helmholtz-Zentrum Berlin (HZB) will intensify its cooperation with Jordanian large-scale research facilities. This was agreed between Prof. Dr. Jan Lüning and representatives of a high-ranking Jordanian research delegation, which visited the HZB at the end of November 2018.
On 27 November 2018, H.E. Dr. Khaled Toukan, Chairman of the Jordanian Atomic Energy Commission and Director of the synchrotron radiation source SESAME, and Dr. Samer Kahook, Manager of the Jordanian Research and Training Reactor JRTR, visited the HZB. They were accompanied by Akram Hayajneh, 2nd Secretary of the Jordanian Embassy in Berlin.
The delegation was informed about the science, the user service and the operation of the neutron source BER II at the Lise-Meitner-Campus. Afterwards, the designated scientific director of the HZB, Prof. Dr. Jan Lüning, led them through the BESSY II experimental hall in Adlershof. In discussions, the delegation talked with representatives from the HZB about the perspectives of Jordan's large-scale research facilities. Another topic was possible support for the Jordanian research reactor against the background of the final shutdown of the BER II at the end of 2019.
HZB has been engaged in SESAME for many years
In addition, the long-standing cooperation between SESAME and HZB was to be further expanded, said the delegates. The synchrotron radiation source SESAME works with the electron accelerator of BESSY I. After decommissioning of that facility, the components were transferred to Jordan in 2002 and successfully installed in SESAME with the help of experts from Germany and other European countries. These components still run very reliably today, emphasized SESAME Director Dr. Khaled Toukan.
Training opportunities for Jordanian scientists
During the meeting, both sides agreed that there would be further training opportunities for Jordanian scientists at BESSY II.
The HZB is also involved in setting up a new beamline for soft X-ray light at SESAME. As reported, the Helmholtz Association will provide 3.5 million euros for this project. The HZB will build an APPLE II undulator for the new SESAME beamline, train the Jordanian team and support them with remote maintenance.
- Electrocatalysts: New model for charge separation at the solid-liquid interfaceHydrogen is at the heart of the transition to carbon neutrality, as both an energy carrier and a reagent for green chemistry. However, large-scale production of hydrogen via electrolysis, as well as the production of many other chemical products, requires significantly cheaper and more efficient catalysts. A precise understanding of the electrochemical processes that take place at the interface between the solid catalyst and the liquid medium is highly useful for developing better electrocatalysts. In the journal Nature Communications, an European team has now presented a powerful model that determines charge separation at the interface, the formation of the electric double layer and local electric potential variations, and the resulting influence on the catalytic activity.
- Environmental Chemistry at BESSY II: Radicals in waterwaysHow do radicals form in aqueous solutions when exposed to UV light? This question is important for health research and environmental protection, for example with regard to the overfertilisation of water bodies by intensive agriculture. A team at BESSY II has now developed a new method of investigating hydroxyl radicals in solution. By using a clever trick, the scientists gained surprising insights into the reaction pathway.
