Accolade and social commitment at the same time: Prof. Dr. Bernd Rech has become a new member of acatech
The German “National Academy of Science and Engineering – acatech” has admitted Prof. Dr. Bernd Rech, an expert in renewable energies, into its circle of members. Bernd Rech has headed the Institute of Silicon Photovoltaics at Helmholtz-Zentrum Berlin (HZB) since 2006 and has been the acting Scientific Director of HZB since May 2017. For many years, and in many capacities, he has been a champion for knowledge transfer. “This appointment is an accolade for his scientific accomplishment, and at the same time involves an honorary mandate,” acatech writes in its press release. The federal- and state-funded academy advises social and political actors on technological matters.
“As a member of acatech, I will weigh in more strongly on debates regarding the issue of our energy supply. Within the academy, I am part of an interdisciplinary team with diverse areas of expertise, which develops recommendations for action for politics and society. It is an exciting and very important set of duties, to which I am very much looking forward,” Bernd Rech says.
Bernd Rech is an internationally renowned expert above all in the fields of photovoltaics and thin-film technology, and has distinguished himself through many successes in technology transfer. He has published more than 300 papers and holds more than ten patents. Rech has also been actively involved for many years in promoting the networking of energy research in Germany. He has been the spokesperson for the “Renewable Energies” research program of the Helmholtz Association since 2008. He is also on the board of the Energy Working Group of the Deutsche Physikalische Gesellschaft. This affords him a complete picture of the scientific and technological challenges involved in converting to a low-carbon energy supply of the future.
acatech welcomes 26 new members
A total of 26 scientists have been newly accepted into acatech. The members of acatech are from the engineering and natural sciences, the humanities, economics and the social sciences, and operate at the interface between science, economics and politics. In interdisciplinary projects, they collaborate with experts from industry and society to develop options and recommendations for action. Subject matters of these projects range from the global energy supply to digitalisation, Industry 4.0 and telecommunications. More information
- Nanosilver as an electrocatalyst for CO₂ reductionVia electrolysis, CO2 can be reduced to CO, a raw material for further chemical products such as fuels. Within the GreenQuest Project, an internation team led by HZB chemist Prashanth Menezes has now systematically investigated catalyst layers made of silver nanoparticles, varying both the size of the particles and their density. The best yield was achieved with nanoparticles with diameters of around 10 nm, which were loosely distributed. Furthermore, they demonstrated how the economic efficiency of the electrochemical cell can be enhanced by integrating an additional chemical reaction at the anode, enabling the simultaneous production of a valuable formic acid, hydrogen, and CO in one device.
- New technique could make MRI more preciseA team of researchers at the University of Stuttgart and HZB has developed a new method that could make MRI even more precise by eliminating “dead time,” a key limiting factor in the measurement process, thereby enabling the detection of signals that are lost using conventional methods. This method opens up new possibilities for medical diagnostics and non-destructive materials testing. The research team presents the new approach in Science Advances.
- Thin nickel films boost green hydrogen productionUltra-thin nickel oxide coatings can significantly improve the performance of anion exchange membrane (AEM) water electrolysers, a promising technology for producing green hydrogen. This was demonstrated by a team led by HZB scientist Dr. Michelle Browne. The results show that a nickel oxide film only 10 nanometres thick outperformed conventional nickel oxide powder electrodes while using less than 1% of the catalyst material. The study is published in the Journal of Materials Chemistry A,
