🎻 Harmonizing Innovation with “ORCHESTER”: Striking the Perfect Chord in Material Science   Last week, Christoph Wilsnack, Jacob Mätje, and Leonid Gerdt, joined the inaugural meeting of the Fraunhofer lighthouse project “ORCHESTER”. Much like a symphony, this project unites experts from various Fraunhofer institutes to create a harmonious collaboration in advanced material research.   Held at Fraunhofer IWKS in Hanau, the two-day meeting allowed all project partners to come together and discuss the innovative pathways we will explore.   Under the baton of Fraunhofer IWM, we are in concert with Fraunhofer IWU, Fraunhofer Institute for Systems and Innovation Research ISI, Fraunhofer IWKS, and FRAUNHOFER IZFP. Our collective goal? To enhance material properties using cutting-edge characterization and simulation techniques.   At Fraunhofer IWS, our particular focus is on boosting the durability and reliability of materials across diverse applications. With our interdisciplinary team, we're ready to tackle the project’s challenges and create symphonic progress in the months ahead.   👉🏼 Stay tuned for more updates and insights as we hit the high notes in material science: https://lnkd.in/eA_JTray   #lightatwork #materials #materialscience Fraunhofer-Leitprojekt ORCHESTER 📸 Fraunhofer IWKS, Fraunhofer IWM

Gegen tägliche Gefahr: Neuer Schutzanzug für Feuerwehrleute in der Entwicklung Feuerwehr-Anzüge schützen vor Hitze und Schadstoffen 🔥, doch bleiben an Kragen, Ärmeln und Bund noch Wege für Gefahrengase offen. Besonders PAK (polizyklische aromatische Kohlenwasserstoffe) bieten ein hohes Krebsrisiko für die Feuerwehrkräfte 🚒 . Das Eindringen der PAK in den Anzug gilt es zu vermeiden. In Zusammenarbeit mit S-GARD, JLM Innovation GmbH, ATS Elektronik GmbH und Norafin Group entwickelten unsere Wissenschaftler und Wissenschaftlerinnen eine tauschbare Filtersensorik für Feuerwehranzüge. In der Feuerwehrkleidung integrierte Fließstoffe nehmen PAK wie ein Schwamm auf und elektrische Sensoren erkennen die Kontamination im Einsatz. 💡 Unsere Aufgabe war es die richtige Aktivkohle für die Filtervliese zu finden. Im MDR Sachsenspiegel gab Felix Spranger, Gruppenleiter für Gas- und Partikelfiltration am Fraunhofer IWS, Einblick in die Forschung, die den Vliesen zugrunde liegt. #lightatwork #firefighters #ProtectiveClothing

Introducing Project CLEANUkraine: Rebuilding Ukraine – Resilient and Sustainable. For inquiries, please reach out to our Fraunhofer IWS scientists Patrick Herwig and Daniel Mai.   👉🏼 Learn more about our groundbreaking project and its vision for a safer future: https://lnkd.in/esKtrCXY   🎇 Motivation For over 70 years, Europe has been grappling with the aftermath of the world wars. A technological revolution is imperative to enhance efficiency and mitigate these legacies. Ukraine faces a similar challenge: each month of ongoing conflict necessitates a year of munitions clearance and destruction. The current manual disposal process is time-consuming and hazardous, often resulting in fatal accidents. A significant technological advancement in disposal methods is crucial for managing this crisis within a feasible timeframe.   ⚡️ Aims and Procedure Current methods for disposing of explosives are fraught with risks, including multiple sawing and mechanical expulsion, which can lead to dangerous impacts. Our innovative approach uses a single saw cut and a thermal process to remove explosives. Inductive heating of the metal shell causes the explosive to melt and be expelled in solid form using gravity. This method, with precise temperature monitoring and control, drastically reduces the danger and disposal time – cutting the delaboration process to a tenth of the current time and minimizing risks.   💡 Perspectives and Innovations The introduction of a mobile technology demonstrator provides a deployable solution for testing and training, paving the way for industrial-scale systems. Our projections indicate a global need for up to 100 dismantling facilities.   Funded by the Fraunhofer-Zukunftsstiftung, this project aims to set a new standard in munitions clearance technology, ensuring a safer and more resilient future for #Ukraine and beyond.   Copyright images: © Fraunhofer IWS   Deutsche Gesellschaft für Internationale Zusammenarbeit GmbH

Introducing project ALABAMA (Adaptive Laser Beam for Additive Manufacturing), which is funded by the European Union with a total of EUR 6 million. On-site at Fraunhofer IWS, the project is spearheaded by Elena López and Francesco Bruzzo.   👉🏼 Learn more about the project: https://lnkd.in/eM8bGRtP 🎥 High-speed video of the LMD process of a single track   🔧 Motivation #Laser-based metal #AdditiveManufacturing (AM) is revolutionizing the manufacturing sector. However, ensuring parts quality and geometrical accuracy in #LaserMetalDeposition (LMD) processes remains a significant challenge. By enhancing the understanding of energy input and its simulation and control during the process, AM can become a cornerstone of industrial applications.   🎯 Objectives and Approaches The ALABAMA project focuses on developing adaptive laser technologies for LMD processes using either powder or wire as feedstock material. By shaping the laser beam, the scientists aim to better control energy input, melt pool geometry, cooling rates, and temperature profiles of the deposited material. The goal is to reduce material defects like pores and micro cracks and to tailor the microstructure of the deposited material through precise laser beam shaping, both temporally and spatially.   🌟 Innovations and Prospects Key innovations include: ◾️ Developing multiscale physics-based models for predictive optimization of the LMD process, reducing the need for costly trial iterations. ◾️ Integrating various laser shaping devices in LMD systems to control the optimal laser energy input as predicted by simulations.   Project partners: SINTEF, Eurecat - Technology Centre, Fraunhofer-Gesellschaft, Luleå University of Technology, Aerobase Innovations AB, IRIS S.R.L., Flowphys AS, Centro Ricerche Fiat, Nordic Additive Manufacturing, GKN Aerospace Sweden AB, Manufacturing Technology Norwegian Catapult, Technovative Solutions Ltd   #LightAtWork #3DPrinting

🔬 Congratulations to Nils Fredebeul-Beverungen, Maximilian Steinhorst, and Dr. Teja Roch on their outstanding new scientific publication on bipolar plates: “Comparison of Magnetron-Sputtered and Cathodic Arc-Deposited Ti and Cr Thin Films on Stainless Steel for Bipolar Plates,” published in Materials by MDPI. 👉🏼 Find the publication here: https://lnkd.in/er-yAJdk   This work investigates the potential of magnetron sputtering and cathodic arc evaporation as suitable coating methods for bipolar plates in PEM #FuelCells. Cr and Ti thin films were deposited onto 0.1 mm SS316L by varying the power and bias voltage. The surface structure and thickness of the coatings were examined using SEM and tactile profilometry. The coating variants were compared based on the electrical and electrochemical properties relevant to bipolar plates. The sputtered Cr thin films achieved the lowest contact resistance values and exhibited a columnar structure with a smooth surface. Regarding electrochemical properties, titanium deposited via cathodic arc evaporation showed a low current density in the passive region and high breakthrough potential. 💡 Overall, both deposition techniques have their individual advantages for preparing bipolar plate coatings. However, Ti thin films prepared via cathodic arc appear to be the most suitable option due to the combination of a high deposition rate, low cost, and good coating properties.   Wishing you continued scientific success in the field of #Hydrogen-based energy storage!   Copyright publication: © Materials 2024, 17(12), 2864   #LightAtWork #BipolarPlates #Energy
