The German Research Foundation (DFG) is funding a new Collaborative Research Centre (CRC) at the University of Bayreuth. The interdisciplinary research of nanostructured functional materials is expected to revolutionise the performance of batteries, solar cells, fuel cells and photocatalysts, thereby opening new perspectives for a sustainable energy economy. The starting point for material-based innovations is a holistic view of the transport of electrons, ions, molecules and heat, and their interactions in the materials. The new CRC 1585 "MultiTrans" will receive a total of around 11 million euros from the DFG over the next four years.
Research is being conducted on biodegradable polymers at the University of Bayreuth. Now an environmentally friendly coating has been developed that could be a full-fledged replacement for the millions of plastic packaging materials used worldwide. The scientists and the industrial Partner have now been awarded the Dres.-Volker-und-Elke-Münch Prize for the Promotion of Science and Research.
Materials made of spider silk can be specifically modified or processed in such a way that living cells of a certain type adhere to them, grow and proliferate. This has been discovered by researchers at the University of Bayreuth under the direction of Prof. Dr. Thomas Scheibel. Cell-specific effects of the materials can be generated by biochemical modifications of the silk proteins, but also by surface structuring of spider silk coatings. The research findings, published in "Advanced Healthcare Materials" and "Advanced Materials Interfaces", are pioneering for regenerative medicine and the production of artificial tissue.
Green hydrogen could play a key role in the energy transition. Electrocatalytic splitting of water into hydrogen and oxygen requires huge amounts of electricity, which means the efficiency of this method for the energy transition is low compared to that of fossil fuels.
Dr. Nataliya Yadzhak from Lviv/Ukraine, postdoctoral fellow and research associate for the Chair for Metals and Alloys at the University of Bayreuth, has been awarded a fellowship from the EU programme "Marie Skłodowska-Curie Actions for Ukraine (MSCA4Ukraine)" on the proposal of the Alexander von Humboldt Foundation. During the two-year fellowship, she will pursue a research project on hydrogen embrittlement of ferritic superalloys at the University of Bayreuth. Of the 26 research projects in Germany funded by the "MSCA4Ukraine" programme to date, it is one of only two engineering research projects.
Researchers at the University of Bayreuth present novel electrospun nonwovens in "Science Advances" that exhibit an unusual combination of high electrical conductivity and extremely low thermal conductivity. The nonwovens represent a breakthrough in materials research: it has been possible to decouple electrical and thermal conductivity based on a simple-to-implement material concept. The nonwovens are made of carbon and silicon-based ceramic via electrospinning process and are attractive for technological applications, for example, in energy technology and electronics. They can be manufactured and processed cost-effectively on an industrial scale.
Ceramic matrix composites are characterized by their ability to withstand very high operating temperatures and shock-like temperature changes and also by the fact that they are not susceptible to wear. Automating a fiber spraying process for the production of oxide ceramic matrix composites and at the same time making it highly flexible is the goal of a new project involving computer science and engineering at the University of Bayreuth. Intuitive robot programming is intended to enable companies to manufacture short-fiber-reinforced oxide ceramic components on demand, even in very small batches. The "FlexFiber" project is being funded by the DFG with a total of around 700,000 euros.
The lack of uniform analytical standards currently prevents the comparability of data on microplastics in the environment. Researchers from the University of Bayreuth and the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) have now, for the first time, compared two automated analysis procedures for microplastic data with regard to the results. Significant deviations were found especially for small particles with comparatively high hazard potential. The study, published in the journal Analytical and Bioanalytical Chemistry, shows that the standardization of analytical procedures must be a key research goal.
An international team with researchers from the University of Bayreuth presents a potentially groundbreaking discovery for nitrogen chemistry in "Nature Chemistry".
The University of Bayreuth is participating in the DFG priority programme "Data-driven process modeling in forming technology" with a new interdisciplinary research project. The project is concerned with two processes that are intertwined in the industrial production of many functional components: shear cutting and collar drawing. The latest data analysis technologies and process chain modeling approaches are intended to ensure efficient and robust production. The project is managed by Prof. Dr. Agnes Koschmider, a process analytics specialist from Bayreuth, and Prof. Dr.-Ing. Verena Kräusel from the Fraunhofer Institute for Machine Tools and Forming Technology (IWU) in Chemnitz.
