Due to their stability and resistance to water and grease, PFAS chemicals (short for per- and polyfluoroalkyl substances) are used in a wide range industries, but they are harmful to health and the environment. Membranes containing PFAS are used in many semiconductor manufacturing processes, for example. Researchers from the Fraunhofer Institute for Applied Polymer Research IAP have now developed a sustainable alternative in the form of an innovative, PFAS-free membrane. The chemically stable, highly permeable polymer membrane has a pore diameter of approx. seven nanometers and enables filtration of the smallest particulate contaminants. The membrane can be customized to meet specific needs, which makes it easy to integrate the new process into existing systems.

Germany is facing major challenges in providing long-term inpatient care for those who need it. According to Statista, the number of people in need of care will increase by 50 percent by 2030. At the same time, the workforce is expected to decrease further over the next few years. AI-based, digital systems offer a way to tackle this challenge: In the “Care-Integrated Artificial Intelligence in the Professional Care Process” (ViKI pro) project, researchers at the Fraunhofer Institute for Industrial Mathematics ITWM, together with their partners, enable specialists in the care sector to identify individual care needs and plan appropriate measures with the support of AI.

Plastics made of polycarbonate are sought-after materials in industrial applications thanks to their versatility and high quality. However, recycling of plastic waste is still running up against limits these days, as mechanical recycling methods do not produce adequate qualities of recycled material for all applications. Together with chemical company Covestro Deutschland AG, Fraunhofer researchers have now developed a method that makes it possible to reclaim the substances originally used to make the polycarbonates. In catalytic pyrolysis, a controlled process of heating in an oxygen-free environment, plastic waste breaks down into its components. Manufacturers can then use the raw materials to produce new plastics.

The Fraunhofer-Gesellschaft will be showcasing nearly 50 exhibits from various disciplines and fields of research at the 2024 ILA Berlin aerospace expo, to be held from June 5 to 9. Fraunhofer institutes are scheduled to present urban aviation systems, satellite technology for quantum encryption, and a drone used to detect forest fires, among other solutions. They will demonstrate how cutting-edge research combines practical solutions with cost-effectiveness and climate action. Fraunhofer researchers are also active in the field of defense and security, where they will be presenting technologies for detection and defense against hypersonic weapons.

Following an invitation from German President Frank-Walter Steinmeier, French President Emmanuel Macron made the first official French state visit to Germany in 24 years. During their three-day schedule, both presidents also visited the Fraunhofer Institute for Photonic Microsystems IPMS in Dresden to highlight the importance of collaboration between France and Germany in ensuring Europe's technological sovereignty, particularly in the field of microelectronics.

Nucleic acid-based medications such as mRNA vaccines offer tremendous potential for medicine and are opening up new therapeutic approaches. These active ingredients must be enclosed inside nanoparticles to ensure that they get to where they are needed inside the body’s cells. The Fraunhofer Institute for Production Systems and Design Technology IPK and FDX Fluid Dynamix GmbH have worked together to develop a technology platform for the production of nanoparticles that can achieve particle quality and stability at levels previously out of reach: FDmiX, short for Fraunhofer Dynamic Mixing Technologies. Swiss chemical and pharmaceutical company Lonza has now licensed the technology for its own good manufacturing practice (GMP) production activities.

Many new drug candidates end up failing because they cause serious side effects in clinical trials even though lab tests involving cell cultures have been successful. This is a common occurrence if the cells used come from animal tissue, for example. Specially prepared cell cultures made from human tissue known as human induced pluripotent stem (hiPS) cells enable greater reliability in testing, thereby also increasing the chances that a drug will be approved. Fraunhofer researchers have developed innovative solutions for optimized production of cells in bioreactors and unique cryotechnologies. This is paving the way for efficient real-world use of these cell cultures in toxicity testing and drug discovery.

For some years now, the trend in the cosmetics and skincare sector has been toward transparency and natural, sustainable ingredients. A growing number of consumers are rejecting cosmetics that contain petroleum-derived mineral oils and silicone oils. As a result, manufacturers are increasingly turning toward plant-based oils, fats, and waxes as substitutes. Working in tandem with Kneipp GmbH, a well-known producer of cosmetic products and other items, the Fraunhofer Translational Center for Regenerative Therapies TLC-RT at the Fraunhofer Institute for Silicate Research ISC is conducting the first-ever systematic tests of the general protective and regenerative effects of plant oils on the skin. The researchers are using a 3D skin model cultured in vitro for their work.

Oxygen saturation in the blood that is either too low or too high can cause lasting physical harm or even death. This is why patients’ oxygen concentrations are monitored continuously in both intensive care and trauma units. However, the pulse oximeters typically clipped onto a patient’s fingertip for this purpose can be unreliable. Researchers at the Fraunhofer Institute for Physical Measurement Techniques IPM have developed a fluorescence-based sensor that measures the oxygen content of people’s breath directly and in real time in an effort to provide accurate figures in the future. The sensor determines the O2 concentration in the respiratory gas according to the principle of fluorescence quenching, which allows conclusions to be drawn about the oxygen saturation in the blood.

Parkinson’s disease is one of the most prevalent neurodegenerative conditions worldwide. It causes motor impairments such as tremors, slow movement, muscle stiffness, and balance problems. Memory can also worsen as the disease progresses. The individual course of the disease cannot be predicted, so experts recommend regular, close patient monitoring to allow for rapid responses to any changes in symptoms. New technological tools aim to facilitate communication between doctors, caregivers, and patients and improve the care situation. In the ParkProReakt project, researchers from the Fraunhofer Institute for Applied Information Technology FIT are working with partners to create a digital platform and app that, used with wearables, will track the course of the disease in an effort to improve quality of life for Parkinson’s patients.
