Ruth Houberts receives the Fraunhofer Founder Award 2016

As a scientist and entrepreneur, Dr. Ruth Houbertz is the recipient of several awards, such as the Joseph von Fraunhofer Prize and the Fraunhofer Founder's Prize. She initially worked at the Fraunhofer Institute for Silicate Research ISC and used it as a base to found Multiphoton Optics GmbH. She wanted to revolutionize data transmission with this company's technology. And the physicist is still convinced today that many current challenges could be solved with optical data transmission. Even though she decided to sell the company at the beginning of 2021.  In this interview,  the Würzburg resident talks about the new "Society6.0" project and the reasons for the sale, her role in science and business and her role as founder. Above all - joy and enthusiasm should not be given short shrift.

Marc Beckett in front of a series of experiments with different nutrient solutions for the GreenUp Sahara project.

For decades, tens of thousands of Sahrawis have been living in refugee camps in the middle of the Sahara. The GreenUp Sahara team is now developing systems to grow vegetables in this hostile environment and thus improve the nutritional situation in these camps. Despite strong competition from the other outstanding projects, the GreenUp Sahara project won the Fraunhofer Alumni Award by a wide margin of the votes of the Fraunhofer alumni and received the prize money of 10,000 euros. In this interview, Marc Beckett, an expert in water technologies and resource recovery at the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB in Stuttgart, explains what the challenges are and what further steps are now being taken. He also describes the adverse living conditions of the people in the camps.

Beyond mp3 - Karlheinz Brandenburg on his new project

Finding an inductee into the “Internet Hall of Fame” among the ranks of Fraunhofer alumni is no surprise: Prof. Dr.-Ing. Dr. rer. nat. h.c. mult. Karlheinz Brandenburg is one of the inventors of the MP3mp3 file format, probably the most important development for the music industry since the invention of vinyl records. Just a few months ago, he resigned as director of Fraunhofer IDMT to enjoy a “not-so-retired” retirement, as he puts it himself. Not content with just being a senior professor at Ilmenau University of Technology, the founder and CEO of Brandenburg Labs has also been enthusiastically working on “the next big thing”: PARty, quasi the acoustic equivalent of virtual reality. In addition to creating a perfect auditory illusion for the listener, the device serves as an acoustic magnifying glass or filter — essentially, it will allow the user to block out or listen closely to specific sounds. The possible applications are plentiful, but the project is still a long way off from being market ready. While the researchers are facing many challenges, as an investor and researcher, Brandenburg has not been scared off. As with the development of the MP3, this new project is the work of a relatively small, tightly knit team.

ecoSUP - Stand-up paddleboard from old wind turbines

© Fraunhofer WKI
Christoph Pöhler wants to develop a SUP that consists of 100 percent bio-based materials and also uses balsa wood that comes from decommissioned wind turbines.

ecoSUP has set itself the goal of 100 percent bio-based paddling pleasure. Christoph Pöhler, a water sports enthusiast from the Fiji Islands, thousands of kilometers away, rowing on a SUP (standup paddle), encounters plastic waste floating in the sea, and he came up with the idea for "ecoSUP". His board is to consist of 100 percent renewable and recycled raw materials. Up to now, almost completely non-biodegradable plastics have been used for such boards. Pöhler wants to change this and he is setting himself major challenges. At the Fraunhofer Institute for Wood Research, Wilhelm-Klauditz-Institut WKI, the doctoral student will find technologies that are unique worldwide and a great deal of expertise for the implementation of this project. We talked with the enthusiastic scientist, water sports enthusiast and world saver about the special challenges and further plans for ecoSUP.

"The future of work will be extremely decentralized" Fraunhofer-Venture Alumna Tina Ruseva

Dr. Tina Ruseva advises the European Commission; she launched the Big & Growing Festival, and she founded her first company right after college. Some companies listed on the DAX are now introducing the mentoring platform from her second start-up, Mentessa. The idea for that came to Ruseva, a native of Bulgaria, because she was so frustrated with many mentoring formats that she finally brought her own concept to market. Networking was also the subject of her work for the Fraunhofer Venture TechBridge, where she created the TandemCamp format, which brought together Fraunhofer scientists with entrepreneurs in growth industries.

“Think Like a Hacker”

To protect your IT, you must think like a hacker yourself, Christian Brandt is sure of that. And he knows what he’s talking about. While at university, he got engrossed in the idea of cracking a security chip. He spent all his free time trying to find the weak points in the system that still to this day “secures” voting machines and at the time was even used in payment systems. Still a student, Christian Brandt was allowed to use the infrastructure of the Fraunhofer Institute for Secure Information Technology SIT. Today he is a researcher in the Cyber-Physical Systems Security Department and heads the Mongoose Group of the Fraunhofer SIT, one of the institute’s hacking teams.

"Future is a good Word” - IFU-Alumna Dr. Edeltraud Leibrock

© Privat
Dr. Edeltraud Leibrock is "proud to be part of the Fraunhofer Community, because Fraunhofer uses innovation and cutting-edge technology to move forward."

Dr. Edeltraud Leibrock loves the opera, the mountains, a range of sports, and this physicist has been supporting businesses with her IT expertise ever since she was 16 years old. It all started with a holiday job working on programs for capturing production data and analyzing cement at a lime manufacturing plant near Regensburg. For her doctoral dissertation, the triathlete swapped Regensburg for the Alps, so that she could perform atmospheric research work at the Fraunhofer IFU in Garmisch-Partenkirchen. After that, she was appointed to the executive board of KfW Bankengruppe as CIO, where she was responsible for IT. But as a Fraunhofer alumna it is only natural for her to ask - #WHATSNEXT. Since 2016, as partner and managing director of Connected Innovations, one of the digital and KI consulting firms co-founded by her, she advises cross-sector enterprises on the complex issues concerning digital transformation.

Alexandre Gatto and Gérard Mourou met at the Photonics Days in Jena.

Car windows display personalized information, react to gestures, measure temperature or provide shade. This sounds like a futuristic dream, but Alexandre Gatto, head of the Microstructured Optics division, and his team at Carl Zeiss in Jena are already developing smart multifunctional glass technologies. According to the IOF alumnus, we can already expect applications for smart glass in the coming years. This is also because he and his team are working on it with great commitment. If, contrary to expectations, the Nobel Prize doesn't work out for the Gatto team, it's due to the statistics - but more about that later. From Marseille, he went to the Fraunhofer Institute for Optics and Precision Engineering IOF for a postdoctoral position. With small intermediate stations, the physicist has remained true to Jena, Optics and the IOF.

"Electromobility for all" - IPT alumnus Dr. Nils Klingbeil

A good and safe car does not necessarily have to be expensive and not necessarily equipped with a combustion engine. The manufacturer e.GO Mobile is turning the German car market upside down, a market previously dominated by traditionalists. Unlike well-known car brands, the young Aachen-based manufacturer concentrates primarily on production technology and thus manages to produce high-quality and affordable electric cars. Dr. Nils Klingbeil brings with him from his time at the Fraunhofer Institute for Production Technology IPT know-how in additive manufacturing and as a process technologist in wire-based deposition welding. In an interview with Fraunhofer alumni, he explains what drives him, why he is fascinated by electromobility and what he has taken with him from Fraunhofer to his new mission as team leader for pre-development.

The Fraunhofer alumnus that ist generating energy from ocean waves

© CalWave

Marcus Lehmann spent eight months at the Fraunhofer-Gesellschaft headquarters in Munich from the end of 2011. Today he runs a company that could make a decisive contribution to humanity's energy supply in the future. The company CalWave Power Technologies Inc., which was co-founded by the Fraunhofer alumnus and which he also chairs as CEO, is developing a power plant that generates electricity from ocean waves. In comparison to wind or solar energy, this process offers various advantages. If the energy of all ocean waves could be captured it would be possible to produce the amount of energy that was consumed worldwide in the entire year of 2008. It is estimated that by 2050 up to 10 percent of Europe's electricity requirements could realistically be covered by energy from the sea.  

The power plants of the young Californian enterprise float under the ocean's surface some distance away from the coastline. This has several advantages: Unlike wind turbines, these plants are under water and thus not visible. They can produce energy even during storms and do not depend on sun and wind. Above all, however, the energy yields from these power plants can be reliably predicted over a long period of time. CalWave Power Technologies was runner up to the U.S. Department of Energy's Wave Energy Prize and is a project of Cyclotron Road, a start-up incubator from the Lawrence Berkeley National Laboratory.
