Every year, around four million people in Europe suffer healthcare-associated infections. Pathogens spread quickly via surfaces such as handrails, handles or touchscreens. To reduce the spread of pathogens, particularly in hospitals but also in public buildings, the EU-funded joint project SanFlex is researching a photocatalytic coating that is (additionally) grafted with super-acidic surface properties. This prevents the adhesion of pathogens and eliminates microorganisms as well. The aim of the project is to develop appropriate coating technologies for the cost-effective production of antipathogenic protective films for touchscreen applications. At the BAU 2025 trade fair in Munich, Germany, from January 13-17, 2025, the Fraunhofer FEP researchers will be presenting their initial results at the joint Fraunhofer stand no. 528 in Hall C2.

As part of the EU project “Phabulous” (grant agreement no. 871810), Fraunhofer FEP and JOANNEUM RESEARCH collaborated to develop innovative micro-optical structures that can be applied to large areas of polymer films using roll-to-roll technology. These structures open up a wide range of possible applications for solar cells or decorative aspects. The Fraunhofer researchers have now also succeeded in developing a new type of bird protection film that is particularly effective thanks to its UV contrast and therefore hardly affects the aesthetics of glass façades. The results will be presented at the Micro-Optics Summit 2024, from December 2 – 3, 2024, in Amsterdam.

Based on an industry-oriented competence portfolio, the Fraunhofer Institute for Electron Beam and Plasma Technology FEP in Dresden offers a broad spectrum of scalable research and development opportunities. Our mission is to apply our technological innovation potential for novel production processes and to harness it to meet society's need for resource conservation and climate neutrality. Considering the growing demand for climate-neutral building materials, new manufacturing processes are also being sought in the construction sector. The Fraunhofer FEP is conducting research into innovative electron beam-assisted processes for increased biogenic limestone synthesis using phototrophic microorganisms in order to support the decarbonization of the cement industry. In this way, the CO2 footprint of cement formulations can be further reduced in the future and fossil limestone can be gradually replaced as a primary resource. This research project will be presented at the BAU 2025 trade fair in Munich, from January 13 – 17, 2025, at the joint booth of Fraunhofer in hall C2, booth no. 528.

After a first run in the winter semester 2023/2024, the University of Applied Sciences (HTW) in Berlin has extended Frank-Holm Rögner's teaching assignment in the M11 module “Historical Methods and Current Developments” in Department 5 “Design and Culture” for the master's program “Conservation and Restoration” from 0.5 hours per week to 1 hour per week. In the future, Rögner will give the lecture series “Cleaning principles and technologies for surface treatment and conservation” during the winter semester.

In the construction and building sector, sustainable solutions for reducing energy requirements and improving the carbon footprint are more in demand than ever. In view of rising energy prices and strict regulations for lower energy consumption in buildings, innovative technologies such as perovskite and organic solar cells offer great potential. However, the cost, durability and efficiency of these solar cells pose a major challenge. As part of the EU-funded PEARL and BOOSTER projects, the Fraunhofer FEP is developing new coating and process technologies that will significantly increase the durability and efficiency of solar cells and sustainably reduce costs and material requirements. At the BAU 2025 trade fair, Fraunhofer FEP will be presenting a number of pioneering technologies and demonstrating their potential applications in the construction and building sector from January 13 to 17, 2025 at the joint Fraunhofer booth in Hall C2, Booth 528.

Piezoelectric coatings play a key role in medical technology, microelectronics and sensor technology, for example in the manufacturing of ultrasound microscopes that examine ever smaller semiconductor components and biological cell structures. However, the increasing demands on the quality and reproducibility of these coatings place high demands on the complex coating processes, which require many parameters to be precisely coordinated. In order to meet this challenge, the Fraunhofer Institute for Electron Beam and Plasma Technology FEP is developing a digital twin of the coating process for piezoelectric thin films as part of the BMBF-funded DigiMatUs project (FKZ 13XP5187D). This enables the digital mapping and optimization of the processes and leads to a significant improvement in the performance and reproducibility of ultrasonic sensors.

On July 1, 2024, Prof. Dr. Simone Schopf was appointed Visiting Professorship in the Department of Circular Economy at the Brandenburg University of Technology Cottbus-Senftenberg. The appointment was made within the framework of the federal and state-funded Women Professors Program III.

Flexible ultra-thin glass is an innovative material that combines the chemical resistance and scratch resistance of glass with the flexibility and weight reduction of plastics, primarily due to its low thickness of ≤ 100 µm. Processing ultra-thin glass requires special handling to prevent breakage during production, which has been a major barrier to its introduction into new applications. Within the Glass4Flex and CUSTOM projects, funded by the Federal Ministry of Education and Research (BMBF) and the Federal Ministry of Economics and Climate Protection (BMWK), project partners at the Fraunhofer Institute for Electron Beam and Plasma Technology FEP developed a unique process chain for the in-line coating of ultra-thin glass. They also evaluated suitable characterization methods for the surface and edge strength of the thin glass to further optimize the material properties through flash lamp tempering. A demonstrator of flexible thin glass with an optical interference layer system will be showcased at glasstec 2024 in Düsseldorf, Germany, from October 22 – 25, in the glass technology live area in Hall 11, Stand No. F27.

A new multi-chamber system for aqueous ultrasonic cleaning at the Fraunhofer FEP will provide flexible cleaning options for industrial component cleaning in the future. This system complements the LinTR training laboratory, which was developed under the leadership of the Fraunhofer FEP together with the Fraunhofer IPA, IWS and IVV Dresden. The learning laboratory offers a comprehensive, modular training concept for industrial parts cleaning for a wide range of requirements and, for the first time, the possibility of training complex cleaning processes in an extended laboratory environment. The new capabilities will be presented during the exhibition at the 32nd Industrial Component Cleaning Conference, September 11 – 12, 2024, in Dresden, Germany.

With the exit from fossil fuels and the achievement of climate targets, alternative technologies are needed for heating and cooling. However, conventional heat pumps and air conditioning systems are noisy, consume a lot of electricity and use refrigerants that are harmful to the climate. This is why scientists around the world are working on electrocaloric heat pumps – they use materials that can change their temperature when an electric field is applied, thereby generating heat or cold. As part of the Fraunhofer lighthouse project ElKaWe, the Fraunhofer Institute for Electron Beam and Plasma Technology FEP has made significant progress in the development of thin films to improve heat transfer in electrocaloric heat pumps. The latest research results will be presented at PSE 2024, September 2 – 5, 2024, in Erfurt, Germany, during the conference and exhibition.
