Scientific Kick-Off

[17.04.2024] The University of Duisburg-Essen marked the start of the new ACTIVE SITES research center with a scientific kick-off event. Prof. Dr. Astrid Westendorf, Vice-Rector for Research at UDE, opened the program with a welcoming address. She emphasized that ACTIVE SITES is an important milestone for top international research at the University of Duisburg-Essen and also plays an important role in the water excellence cluster application REASONS.

Prof. Dr.-Ing. Stephan Barcikowski, spokesperson for ACTIVE SITES, began by summarizing the objectives of the research center and presenting the disciplines involved, which use their combined expertise to investigate the processes at the active centers of ultrafast and dynamic chemical reactions in their respective functional environment. In a series of presentations, the challenges and opportunities of the different research areas Preparation, Operando and Ambience were discussed. Read more

Two-day kick-off meetingCollaboration with Berkeley Lab

[Berkeley, 29.02.2024] In a two-day kick-off meeting at Lawrence Berkeley National Laboratory (Berkeley Lab) collaboration in the areas of genomics, structural biology, bioimaging and water research were intensified. The meeting was attended by key representatives from the DOE Joint Genome Institute (JGI), the Molecular Biophysics and Integrated Bioimaging (MBIB) Division and the Energy Storage & Distributed Resources Division of Berkeley Lab. Nine UDE scientists traveled to San Francisco Bay as representatives of ACTIVE SITES (ASC), the Center for Water and Environmental Research (ZWU) and the One Health Ruhr (OHR) research center. Read more about the LBNL-Visit.

Participants included Alexander Probst, Stephan Barcikowski, Lydia Didt, Anzhela Galstyan, Shirley Knauer, Beate Krok, Oliver J. Schmitz, and Kathrin Thedieck from UDE, alongside Nigel Mouncey, Hoi-Ying Holman and Tanja Woyke, Lauren Belisario, Greg Hura, Jan Kern, Nikos Kyrpides, Trent Northen, Robert Kostecki, Susan Tsutakawa, Junko Yano, and Petrus Zwart from Berkeley Lab.

International collaboration Visit of the Bioscience Division at NASA Ames Research Center

[23.02.2024] Our multidisciplinary UDE delegation with members of the research centers ACTIVE SITES, ZWU and One Health met with Parag Vaishampayan and his team of the Space Biosciences Division at NASA's Ames Research Center in California's Silicon Valley. Together we held a one-day workshop to explore potential research collaborations for the development of methods in the fields of nanoscience, biology and water research. The presentations and lab tour gave us a closer look at NASA's cutting-edge programs, like the Space Biology Program, the Human Research Program, and the Open Science Program OSDR. Numerous scientific topics and synergies for potential future project collaborations were identified.

Funding of the research project "Natural Water to H2" for sustainable hydrogen production

[20.10.2023] NRW Science Minister Ina Brandes presented a three-million-euro grant to ACTIVE SITES vice speaker Corina Andronescu for the "Natural Water to H2" project. Within this research project, the University of Duisburg-Essen aims to achieve a breakthrough for more sustainability in hydrogen production. The Ministry of Culture and Science is funding the project as part of NRW's ´Profilbildung 2022´with three million euros for three years. In the long term, the new research profile will be located at the new ACTIVE SITES research building.

In the new research project "Natural Water to H2" the research fields of "water research" and "hydrogen" are being brought together at the UDE. 14 research groups of the UDE and 22 associated partners from academia and industry will work together to increase the sustainability of hydrogen production through anion exchange membrane (AEM) water electrolysis. For the first time, a fundamental understanding is to be gained of how water quality, electrodes and membranes influence each other. Using organic and inorganic lead substances, it will be quantified how or to what extent water needs to be purified before and during electrolysis. ​The projects involved cover multiple disciplines including water electrolysis, electrocatalysis, water technology and purification, membrane technology, nanomaterial synthesis, surface science and theoretical chemistry.  UDE Press release

Recent Publication in Water Research - Microorganisms ward off parasitesPotential new function of CRISPR-Cas system discovered

[28.07.2023] Microorganisms use the CRISPR-Cas system to fight viral attacks. In genetic engineering, the microbial immune system is used for the targeted modification of the genetic make-up. Under the leadership of Professor Dr. Alexander Probst, microbiologist at the Research Center One Health Ruhr at the Research Alliance Ruhr a research team has now discovered another function of this specialised genomic sequence: archaea – microorganisms that are often very similar to bacteria in appearance – also use them to fight parasites. The team has now published its findings in Nature Microbiology. Read the full press release here.

New theoretical approach addresses the oxygen evolution reaction (OER)

The latest publication of ACTIVE SITES member Kai Exner addresses the oxygen evolution reaction (OER), a process of high relevance due to its application in electrolyzers for hydrogen production or metal–air batteries for energyconversion and storage. Until now, the application of electronic structure theory to improve OER materials has been based on a supposed single reaction mechanism. Kai Exner was able to show that, especially in the case of highly active OER catalysts, several reaction mechanisms take place depending on the applied electrode potential, with the favored reaction pathway changing with increasing overvoltage. The theoretical approach presented can also be applied to other electrocatalytic processes. View  article , view UDE press release.
