New UDE Research MagazineFocus on Water

September 2022 

The new UDE research magazine shows how scientists find and implement solutions to the pressing questions of our time. It starts with the main topic of water.

Into the lab, out into the field or immerse yourself in the study: the research magazine offers exciting insights across science - in German and English. Each issue is planned around a focal point. The first is water. It is the basis of all life and an increasingly scarce resource. Extensive research is therefore conducted on it at the UDE and it forms one of our five profile focal points. Discover how the health of a body of water is measured, why a once dead river is now considered a global model and how a journey through time is possible through flora and fauna.

The research magazine is now online.
Print copies are available from the Press Department:

We hope you enjoy reading it!

Membrane researchHumboldt Fellow in Technical Chemistry

September 2022 

Water is becoming increasingly scarce on our planet. And the available water is often polluted. Dr Libing Zheng wants to optimise purification. He is currently a scholarship holder with Professor Mathias Ulbricht in Technical Chemistry.

Water purification is now standard in many countries. "In industry, we could also use seawater," says Libing Zheng from the Chinese Academy of Sciences. Membrane distillation (MD), for example, makes this possible.

At the UDE Dr. Zheng would like to use magnetic particles to combat fouling, among other things.

Cold Brew CoffeeUDE chemists develop brewing technology

August 2022 

Dr Anna Rosa Ziefuß and Tina Friedenauer from AG Barcikowski have developed a new brewing process: Instead of letting the coffee grounds steep at room temperature for at least twelve hours, their process takes only three minutes - thanks to lasers. They published their result in npj Science of Food.

Now the two want to start up LEoPARD. LEoPARD stands for Laser-based Extraction offers Pure and Advanced Refreshment Drinks - which shows where the two see the market potential. "It's not the coffee, but the laser-based manufacturing process that has a huge event character. So we envision renting out appropriate laser systems for events, like weddings. But you could also rent it out or license it to coffee houses." In addition, the process may also become interesting for the beverage industry in the future, as tea or matcha could also be produced this way.

A video of the process is available on the Instagram page.

Research building approvedNew methods for top-level research

July 2022 

Funding for the new ACTIVE SITES research building has been secured: Following the Science Council, the Joint Science Conference (GWK) has now also given green light for the new 70-million-euro building. The costs are shared by the federal and state governments and the UDE. With ACTIVE SITES the UDE gains a centre of international renown at which so-called active sites are researched in an aqueous environment. These have an important role in chemical and biological processes, such as energy conversion, water purification and active subtances development. Starting 2026, scientists from various disciplines will conduct research together in state-of-the-art laboratories.

The goal of the project is to develop new methods based on large-scale instruments that use knowledge from different disciplines to study active centres. Active sites are understood to be binding and reaction sites for molecules. The challenge here is to observe the course of reactions live and in their natural environment. "Until now, active sites have mostly been analyzed either in artificial environments or only indirectly, by comparing them before and after the reaction," explains Prof. Corina Andronescu, a technical chemist and deputy spokesperson of ACTIVE SITES. "We want to visualize the reaction in the natural aqueous environment. To do this, we will develop a set of methods that specifically brings together and combines expertise from the different fields of chemistry, biology, physics and engineering. This approach of working across disciplines as well as across substances is unique so far."

Nature publicationStudy on microbes in groundwater

July 2022 

Scientists from Jena have used a highly sensitive measuring method to investigate in more detail how microorganisms in rocks are able to produce biomass from inorganic substances. Alexander Probst, UDE Professor of Aquatic Microbial Ecology, and his colleague Till Bornemann were also involved in the investigations. They carried out bioinformatic analyses.

The team was able to show for the first time the extent to which these communities produce biomass in absolute darkness. The results provide new insights into the functioning of these subterranean ecosystems, which provide an essential part of our drinking water.

5.3 million euros for power-to-X platformClimate-neutral chemistry

April 2022 

Electricity from fossil fuels should disappear from the production chain as far as possible - not only to protect the environment, but also to become less dependent on imports. NRW wants to get a little closer to this goal and is now funding the construction of a power-to-X test platform at the UDE with 5.3 million euros. Mitsubishi Heavy Industries is the overall leader of the SPIN* project. Other project partners are Evonik Industries and Fraunhofer (FhG) UMSICHT.

"With the Power-to-X test platform, we are connecting the electricity, heat and gas grids as well as the mobility sector. This so-called sector coupling is a key technology on the way to the energy transition and the targeted climate neutrality," explains Professor Klaus Görner, the scientific director of the project. At the same time, the UDE researchers have the necessary infrastructure with the plant to manufacture further products whose intermediate component is energy in the form of hydrogen. The project will initially be funded for three years.

From students for studentsHydrological-Water Management Conference (HYWATA) 2022

March 2022 

The hydrological-water management conference, HYWATA, is a four-day interdisciplinary networking event for students of all disciplines related to water (hydrology, hydrobiology, water management, cultural engineering, hydraulic engineering, geosciences, process engineering for water treatment and civil and environmental engineering).

HYWATA was held for the first time in 2012 at the Technical University of Dresden. Due to its success, there were further "HYWATAs" in Dresden and in Vienna in 2015, 2017 and 2018. In 2022, a group of students from the University of Duisburg-Essen (UDE) will bring this successful concept to Essen for the first time. The UDE team consists of students from the DVGW university group AquaSmarTech, the study programme "Management and Technology of Water and Wastewater" and the study programme "Water Science".

The unique history and landscape of the Emscher and Ruhr region is the reason for the many water management associations and societies, and it also explains the high presence of corresponding cultural and research institutions - most of which are in intensive cooperation with the diverse water study programmes at the UDE. HYWATA 2022 will be held from 8 to 11 June at the Essen campus under the motto "The Challenge of Water Management in the Emscher and Ruhr Region - History, Present and Future".

Registrations from internal and external students are open from 8 March to 8 April.

Nature publicationGreenhouse gas fuel for microbes

January 2022 

With an ejection height of up to 60 meters, the geyser in Andernach is the world's largest cold-water geyser. Dr. Alexander J. Probst, biology professor at the UDE Faculty of Chemistry, found out which single-celled organisms live there and how they bind CO2. The results have been published in the journal Nature Communications.

For Probst and his doctoral student Till Bornemann, what is particularly interesting is what happens at the very bottom of the geyser. The UDE researchers most frequently found so-called altiarchaea. Professor Probst is also researching these single-celled organisms in a sulfur spring near Regensburg.

The interdisciplinary study involved UDE scientists from analytical chemistry (AG Schmidt), geology (AG Schreiber) and microbiology (AG Probst). gGmbH provided support, for example, with long-term measurements of water chemistry. Further analyses are planned in the "MultiKulti" project, which is being funded by the German Federal Ministry of Education and Research with 2.5 million euros over three years.

International StudyMicrobes and viruses found in the Atacama Desert

November 2021 

The Atacama Desert stretches along Chile's Pacific coast over 100,000 square kilometers. It is one of the most arid places in the world. Annual precipitation averages 0.5 mm, less than Death Valley in California.

Prof. A. Probst (Aquatic Microbial Ecology, UDE) and his international team have now discovered unicellular archaea there that have developed numerous resistances. They occur under rock-covered parts of the desert, where they are protected from UV radiation. The boulder-covered areas comprise up to a quarter of the extremely dry core of the Atacama Desert. So far, no life has been searched for there.

For space exploration, he said, this finding is important. "The Atacama Desert is considered a Mars analog." If terrestrial life strikes the red planet unplanned, it probably spreads widely, as the viruses' dispersal patterns showed. In addition, he said, there could be zones of life possible under Martian debris, just as there are here, despite drought and UV radiation.

The study involved researchers from the Technical Universities of Berlin and Duisburg-Essen, the GFZ German Research Center for Geosciences, Helmholtz Zentrum München, the Leibniz Institute of Freshwater Ecology and Inland Fisheries, and the U.S. universities of Harvard (Cambridge) and Rhode Island, Kingston.

New viruses in groundwater International study on lytic archaeal viruses.

August 2021

Prof. Probst (Aquatic Microbial Ecology, UDE) and an international group of researchers found altiarchaea in the groundwater of the Mühlbach sulfur spring in Isling, Regensburg. They came across the unknown viruses that infect the microorganisms when analyzing water taken from a 35 m deep aquifer at the sulfur spring. In the labaratory, the viral pathogens cannot yet be grown in the laboratory and are therefore nameless.

Fluorescence of noble metal Nanoclusters.

Juli 2021

In this work, researchers led by Ms. Ziefuss (Technical Chemistry I) demonstrate the size-controlled generation of ligand-free gold nanoclusters by a modern laser-based synthesis method. These species exhibit bright blue fluorescence whose intensity is a direct function of the surface charge density, which can be easily tuned by the pH of the surrounding medium. The researchers have succeeded for the first time in producing such small particles without organic biomolecules on the surface and observing the optical properties.

The study, in which several UDE working groups were involved, was carried out as part of a DFG research project. The research topic offers thematic points of contact for photocatalysis research, which is being carried out as part of the FutureWaterCampus (FWC).
