✨🎄Seasonal Greeting from BAM8.3 - Thermographic Methods!🎄✨ As the holiday season heats up, we want to take a moment to thank our amazing team, colleagues and cooperation partners. You’ve been a constant source of heat for our success – thank you! 🔥 📸 And of course, enjoy our traditional group photo, where everyone has a shining warm smile! 🎄🎀 May your holidays radiate warmth, joy, and cherished moments with loved ones! ✨🎉

Our colleague Michael Stamm talked to the Weather Guard Lightning Tech podcast about the project KI-VISIR and the work his department does to implement modern inspection techniques for rotor blades of wind turbines. Watch the video: https://lnkd.in/dmqD5uzn Together with René Harendt, CTO at Romotioncam, they explain the inspection method that works while blades are in motion. The method uses a new 840 mm focal length camera and thermal imaging data. Find more information on the project here: https://lnkd.in/dVTt5sFP For the reference data set see https://lnkd.in/dpzz_Czx

Dear colleagues and friends, the year 2024 is nearly over and 2025 is at the gates. It was full with exciting projects and new findings, beginning from in-service welding of hydrogen pipelines, via the avoidance of cold cracking in offshore foundations to the diffusion and trapping in high-pressure hydrogen-charged high-entropy alloys. But everything would not have been possible without the right and highly motivated people from Bundesanstalt für Materialforschung und -prüfung especially our PhDs (e.g. Nina Schröder, Denis Czeskleba, Kjell E., Sebastian Kaiser, Karsten Wandtke, Martin Hübner, Philipp Lorenz Liepold). And of course, everything AND only with right (old and many new) partners from academic and industry from all over the world 😀👌. Personally, I am really thankful that I am since May 2024 a "permanent" part of BAM in the Division 9.4 - Weld Mechanics of Prof. Thomas Kannengiesser). Thank you all, Merry Christmas and a happy, healthy New year! On behalf of the entire team, Michael (Image credit: "Monicore" via Pixabay)

Sorry, no Christmas cards. Not my style. However, here is a preview on a few things we will soon be doing in Division 8.2 "NDT methods for civil engineering" at Bundesanstalt für Materialforschung und -prüfung. 1) We will start our most recently confirmed project "ZfPRückbau" on NDT tools for #nuclear #decomissioning with Acoustic Control Systems - ACS Group and Mondaic Ltd. Open positions (PhD/PostDoc) will be announced in January. 2) In April, the Deutsche Forschungsgemeinschaft (DFG) - German Research Foundation #SFB1683 on re-use of #concrete non-prefabricated modules, coordinated by Ruhr-Universität Bochum will start. We will work mainly with Prof. Iurie Curosu. PhD-position #applications will be possible from February. 3) The EXIST - Existenzgründungen aus der Wissenschaft project CommoD is up to full speed (after just 2,5 months!) - first installations with active #ultrasonic #monitoring due soon. 4) We are looking forward to several large-scale #NDT and #SHM bridge-related experiments - wait for posts in February. 5) Personally, I am looking forward to activities related to #muon #tomography. I am still convinced that this might be of great value for the assessment of our ageing #infrastructure. Mobile detectors are on their way and in the making - I expect exciting results in 2025/2026. Muons rock! 6) Hope to see the #NDTCE family at NDT-CE 2025 in September in Izmir. Abstract submission ends on Friday. Did I forget something? Probably a lot. One more thing: Our famous advanced #NDTCE #training #workshop will most probably return in 2025 in an upgraded form with John Popovics, Wallace W.L. Lai, Thomas Schumacher, Arezoo S. Imani, Stefan Maak, Christoph Strangfeld, Thomas Kind and others. Save the date: June 25th - July 1st. Mail to ndte-training@bam.de if you are interested. Have good start into 2025!

Mit dem WeldMagnet der WeldNova GmbH können die Kosten und die Produktionszeit bei der Herstellung von Windrädern deutlich reduziert und Ressourcen massiv geschont werden. 🎡 🌬️ Die #Innovation ist nicht weniger als eine Revolution des Schweißprozesses für Windkraftanlagen. Für diese wegweisende Technologie gibt es deshalb verdientermaßen den Innovationspreis 2024! 👏 #innopreis

Unser #PaperdesMonats Dezember aus dem Themenfeld #Material hat herausgefunden, dass hybride und korrelative #Imaging-#Spektroskopie zu einem besseren Verständnis der #Lasermaterialbearbeitung führt. Die Lasermaterialbearbeitung mit ultrakurzen Laserpulsen bietet eine mögliche Lösung für dieses Problem. Mit dieser Technik lassen sich Oberflächen sehr lokal mit einer minimalen Größe der Wärmeeinflusszone abtragen oder modifizieren. Um diesen Prozess zu verstehen und zu optimieren, ist es von entscheidender Bedeutung zu verstehen, wie die Laserbearbeitung Materialien beeinflusst, insbesondere im Bereich der Modifikation unterhalb der Ablationsschwelle. https://lnkd.in/eC3kzptu

How can we distinguish 3D-printed components that were produced with identical parameters? We use their microstructural fingerprint as an authenticator! Building on our previous work at Bundesanstalt für Materialforschung und -prüfung within the QI-Digital project, we are now transferring this idea to Additive Marking GmbH as part of our BMBF #DATIpilot "DOI4AM". This is our contribution to enhancing the security and product protection of additively manufactured components. Looking forward to an exciting collaboration! 🚀 Special thanks to Kanhaiya Gupta, Konstantin P., Alexander Ulbricht and Heike Q.!

Yesterday, on the brim of the African Materials Research Society Conference in Kigali, within the framework of the #Circular B-I/O project, Kabibi Kamashanju, Ph.D and I had the pleasure to visit the Kinazi Cassava Plant Ltd and see the processes at the factory along with quite many very valuable resources that today still occur as 'waste'. Great thanks to CEO Alex van de Langenberg to not only invite us but to also drive us the long off-road track to the amazingly beautiful location of the factory and providing us with so many valuable information. Thanks also for your vision to make all process by-products useful and not to waste any resource. I see a pre-cast factory, that in most creative case could even be a standalone production only from the byproducts of cassava food processing, including the production of plasticising chemical admixtures based on #sugar #chemistry instead of petrol based chemistry. I do hope that Circular B-I/O, which is a project funded by the VolkswagenStiftung, can provide the data that support making bio-based byproducts a real business case that creates local livelihoods and economies - climate friendly, renewable, circular, and socio-economically equitably. Circular B-I/O is a collaboration between Bundesanstalt für Materialforschung und -prüfung, Institute of Cement and Concrete(ICC), Meru University of Science and Technology (MUST), and SRH Berlin University of Applied Sciences.

Unser #PaperdesMonats aus dem Themenfeld #Energie untersucht die Materialverträglichkeit von #Polyethylen hoher Dichte (PE-HD) in Bezug auf Behälter und Rohre für die Lagerung und den Transport von #Biodiesel. Biodiesel verhält sich in vieler Hinsicht anders als herkömmlicher #Diesel, was Auswirkungen auf die Dauerhaftigkeit und den sicheren Einsatz der verwendeten Materialien haben könnte. Ein kritischer Aspekt ist der sogenannte „umgebungsbedingte #Spannungsriss“ (#ESC – environmental stress cracking). Die in dieser Studie untersuchten PE-HD-Materialien wurden vergleichend hinsichtlich #Spannungsrissbeständigkeit und #Risswachstum in Kontakt mit Biodiesel und Diesel untersucht – mittels Full-Notch Creep Test (#FNCT). Verglichen mit Referenz-Testmedien zeigte sich, dass beide Kraftstoffe die Rissausbreitung im Material beschleunigen, Biodiesel jedoch nur halb so stark wie konventioneller Dieselkraftstoff. https://lnkd.in/ePDUJwBf
