ZEMOS: Home of Solvation Science @RUB

The first research building for Solvation Science in the world. Hosts over 100 scientists, it's home to 6 disciplines.

WHAT is RESOLV?

The Cluster of Excellence RESOLV is an interdisciplinary research project of the Ruhr University Bochum and the TU Dortmund University, as well as four other institutions in the German Ruhr area. Since 2012, about 200 scientists cooperate to clarify how the solvent is involved in the control, mediation and regulation of chemical reactions. Our research is essential to advance technologies that could reuse CO2 for chemicals production, increase the efficiency of energy conversion and storage and develop smart sensors. RESOLV is funded by the German Federal Government and the state of North Rhine-Westphalia with 42 Mio. EUR over the period 2019-2025.

Metallic nanocatalysts imitate the structure of enzymes

JACS: In catalysis, nature is sometimes more efficient than artificial systems. Researchers have copied one of the tricks.

Natural enzymes have certain structural characteristics that give them particularly high catalytic activity. The trick: their active centres, where the catalysed reactions take place, are located in channels inside the enzymes, where the conditions for the reaction are particularly favourable. A German-Australian research team has transferred this principle to artificial catalysts. In tiny metal particles, they created channels in which a chemical reaction could take place. The reaction was three times more efficient inside the particles than on the surface.

The results are described in the Journal of the American Chemical Society, published online on 23 September 2018 by researchers from the RUB Center for Electrochemical Sciences and colleagues from the University of New South Wales.

Enormous potential

According to the authors, the results show the enormous potential of nanozymes. They now want to test the concept with different chemical reactions and investigate the basics of increased catalytic activity in more detail.

"We would like to be able to imitate the way enzymes work even better in the future," says Professor Wolfgang Schuhmann, Center for Electrochemical Sciences. "Ultimately, we hope that the concept will contribute to industrial applications in order to make energy conversion processes more efficient using electricity generated from renewable sources."

Video: The solvent of life

Water. It’s the most abundant substance on Earth´s surface and in our bodies. But is water a passive spectator in the animated scene of bio-chemical reactions inside our cells? RESOLV scientists investigate the important role that water plays in the most diverse processes, bringing solvation science into the spotlight.

igss summer school

The integrated Graduate School Solvation Science hosts an annual Summer School at the Ruhr University Bochum. The school always takes place during Whitsuntide and is an integral part of the GSS students' training during their doctoral studies. This year's iGSS Summer School took place from the 11th to the 14th of June, 2019.

International speakers, suggested by the students themselves, are invited to give keynote talks on their research in the field of Solvation Science. The Advanced Laboratory Modules give the students an excellent opportunity to learn new and interesting experimental and theoretical techniques within a specific research topic of their own choice.
