Cleaning up #Christmas 2.0 🎅🏻. The holiday season – a time for baking and joy (and, let’s be honest, a lot of cleaning afterward). But what if we told you there’s a futuristic solution for those sticky messes? Search for: “the #Laser“!   This cutting-edge technology can clean just about anything: chocolate 🍫, pudding, even peanut butter, from baking molds or rollers. No scrubbing required! With unparalleled precision, these lasers can selectively degrease, strip paint, or remove rust from stainless steel surfaces. ⚡️ In industry, lasers are a game-changer for cleaning purposes. They clean tiny areas in #Microelectronics, uncover joining points and electrical contacts on painted steel panels, and even help preserve cultural artifacts – all without damaging the underlying surfaces. As precise as these lasers are for cleaning, we’ll leave it up to you whether your holiday cookies need that level of perfection. Either way, cheers to the science making life (and Christmas cleanup) a little brighter! 🎄 What do you think? Team laser or trusty sponge? 👉🏼 Here`s more about high precision lasers: https://lnkd.in/eRgEqGV5 #LightAtWork #Electronics

Herzlichen Glückwunsch Josephin Bischoff 💐 zum Gewinn des BIC-FWF-Förderpreises für herausragende studentische Leistungen bei der Umsetzung von Innovationen in der Region Zwickau. Feierlich überreicht wurde ihr die Urkunde von Prof. Dr. Matthias Richter (Westsächsische Hochschule Zwickau und Vorstandsvorsitzender des BIC-FWF e. V.). 𝗡𝗲𝘂𝗲𝘀 𝗟𝗶𝗰𝗵𝘁 𝗮𝘂𝗳 𝗞𝗲𝗿𝗮𝗺𝗶𝗸𝗲𝗻 💡: Optische Werkstoffe für extreme Bedingungen Ob in der chemischen Industrie oder in der #Raumfahrt – Materialien, die auch unter extremen Bedingungen zuverlässig funktionieren, sind gefragter denn je. Transparente polykristalline Keramiken gehören zu diesen Hochleistungswerkstoffen. Sie kombinieren beeindruckende Eigenschaften: hohe Schlagfestigkeit, Langlebigkeit sowie Widerstandsfähigkeit gegen Hitze, Druck und chemische Angriffe. Gleichzeitig sind sie kostengünstiger und flexibler herstellbar als herkömmliche Alternativen wie Glas oder einkristalline Werkstoffe. Josephin Bischoff, Absolventin der Fakultät 𝗣𝗵𝘆𝘀𝗶𝗸𝗮𝗹𝗶𝘀𝗰𝗵𝗲 𝗧𝗲𝗰𝗵𝗻𝗶𝗸 an der Westsächsischen Hochschule Zwickau (WHZ), widmete ihre Masterarbeit genau diesem spannenden Thema. In Kooperation mit dem Fraunhofer-Anwendungszentrum für Optische Messtechnik und Oberflächentechnologien AZOM und dem Fraunhofer IKTS untersuchte sie das Material 𝗦𝗽𝗶𝗻𝗲𝗹𝗹 – eine besonders robuste transparente #Keramik. Mit hochmodernen Analysemethoden wie der Weißlicht-Interferometrie analysierte sie den Brechungsindex des Materials, einen zentralen Parameter, der die optischen Eigenschaften beschreibt. Dabei legte sie besonderes Augenmerk auf die Dotierung mit 𝗦𝘁𝗿𝗼𝗻𝘁𝗶𝘂𝗺𝗼𝘅𝗶𝗱 (𝗦𝗿𝗢) und den Einfluss verschiedener Herstellungsverfahren. Die Ergebnisse der Arbeit zeigen: Die Nachverdichtung der Keramik durch Heiß-Isostatisches-Pressen (HIP) beeinflusst die optischen Eigenschaften erheblich. Zudem wurden bei der Dotierung mit SrO kleinste Bereiche entdeckt, in denen die Konzentration leicht variiert. Diese mikroskopischen Unterschiede führen zu subtilen Schwankungen im optischen Verhalten der Keramiken. Die Erkenntnisse aus der Arbeit leisten einen wichtigen Beitrag zur Weiterentwicklung transparenter Keramiken. Sie könnten helfen, neue Standards für den Einsatz dieser Werkstoffe in High-Tech-Anwendungen zu setzen – von der #Sensorik bis hin zu optischen Systemen in der Raumfahrt. Herzlichen Glückwunsch und weiterhin maximale Erfolge! 🍀 👉🏼 Weitere Informationen finden Sie hier: https://lnkd.in/etQAJbxR #LightAtWork #Physik Copyright Foto: © Fraunhofer IWS

We are deeply honored to be named finalists for the JEC Composites Innovation Awards 2025 in the category “Aerospace – Parts” ✈️ with the Multifunctional Fuselage Demonstrator (MFFD) – the world’s largest thermoplastic #Aircraft structure. Our innovative CONTIjoin technology, developed at Fraunhofer IWS, enabled the manufacturing of the longitudinal joint for this real-size demonstrator. This breakthrough was achieved in collaboration with outstanding partners from industry and research under the European Union’s Clean Sky 2 campaign. Among others, multiple Fraunhofer institutes played a pivotal role as project partners 🙌🏼. What makes CONTIjoin so revolutionary? This CO2 laser-based technology joins large-scale thermoplastic structures in a single process step – no additional fasteners or adhesives needed. It creates a mono-material joint by laying up multilayered carbon fiber-reinforced laminates, making the process more efficient and sustainable. We are incredibly proud to contribute to the advancement of aerospace innovation and cannot wait for the award ceremony in Paris on January 13, 2025. 👉🏼 Learn more about the MFFD project here: https://lnkd.in/em24pfeX If you have any questions, please don't hesitate to contact Maurice Langer or Eric Pohl. #LightAtWork #JECWorld #Composites #Laser, JEC Group Copyright image: © CLEAN AVIATION / Fraunhofer IWS
