It offers a variety of possibilities in the areas of education and training. Here, interactive and immersive learning experiences increase motivation and learning success. AR also enables the specific support of workers in the production environment. When dealing with complex tasks, AR applications help workers to increase efficiency and quality. Based on the developments of the BMBF collaborative project KORESIL, this paper contains an overview of the current application scenarios of AR in teaching and industry. The outlook provides an analysis of this technology's potential and identifies current challenges in hard‐ and software.","PeriodicalId":9912,"journal":{"name":"Chemie Ingenieur Technik","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142194021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Die Energie- und Rohstoffwende macht hier keine Ausnahme. Die Transformation zu einem klimaneutralen und prosperierenden Standort schreitet voran und stellt dabei kontinuierlich neue Herausforderungen. Nach der Frage nach einer Versorgung mit erneuerbarer Energie rückt nun zunehmend die Erkenntnis in den Mittelpunkt, dass eine Energiewende ohne Moleküle, also ohne chemische Energiespeicher, nicht darstellbar ist. Die Chemieindustrie sowie einige Bereiche im Mobilitätsektor wie Flug-, Schiffs- und Schwerlastverkehr werden auch weiterhin Kohlenwasserstoffe als Rohstoff benötigen, die auf lange Sicht klimaneutral bereitgestellt werden müssen. Defossilisierung bedeutet in diesem Zusammenhang das Schließen von Kohlenstoffkreisläufen, die sich aus den sogenannten unvermeidbaren CO₂-Entstehungen der Industrie speisen. Carbon Dioxide Capture and Utilization (CCU), ist der erforderliche Ansatz, um CO₂ aufzufangen und Kohlenwasserstoffe bereitzustellen – also Kohlenstoff zu recyclen. Dabei ist CCU viel mehr als eine Übergangstechnologie, der das Label „Stranded Investment“ oder wahlweise „Log In“ anhaftet. Auch in einer klimaneutralen Welt werden diese Technologien benötig. Vielleicht mehr denn je, auch mit aus der Atmosphäre entzogenem CO₂. So ist CCU neben Carbon Dioxide Capture and Storage (CCS) und Carbon Dioxide Removal (CDR) auch fester Bestandteil der Carbon-Management-Strategien der Europäischen Union und der deutschen Bundesregierung.</p><p>Eine wichtige Investition in die Zukunft stellt das BMBF-Verbundprojekt Carbon2Chem^® dar, das CCU-Technologien und -Systeme entwickelt und erprobt. Die direkte Umsetzung von CO₂ aus dem Stahlwerk, zusammen mit Wasserstoff zu Methanol, konnte im Vorhaben demonstriert werden. Abgesichert durch die Messresultate kann im nächsten Schritt die technische Skalierung erfolgen.</p><p>Mit dem nun vierten Themenheft dokumentiert unser Verbundvorhaben Carbon2Chem^® eine zweite Projektphase (2020–2024). Trotz der Vielzahl an Veränderungen im Umfeld des Vorhabens gelingt Carbon2Chem^® mit großer Flexibilität aller Beteiligten ein kontinuierlicher Entwicklungsprozess, der die volatilen Rahmenbedingungen abbildet. Auch die Transformation der heutigen Stahlindustrie in die zukünftige Stahlproduktion wird im Projekt begleitet. Daneben haben Partner aus der Zement- und Kalkproduktion und der thermischen Abfallbehandlung dazu beigetragen, dass die Technologiebausteine und Systemkonzepte auf weitere Branchen übertragen werden können, bei denen auch in Zukunft noch CO₂ in größeren Mengen entsteht. Mit jedem neuen Baustein nähert sich das Projekt stetig der industriellen Umsetzung.</p><p>Die Partner aus Industrie und Wissenschaft haben trotz der Corona-Phase tagtäglich zusammen das Vorhaben vorangetrieben.

This includes digital laboratories that in return change social dynamics and interaction patterns of students. This contribution takes the first step of examining gender‐specific teamwork and leadership of groups conducting a digital laboratory in fluid mechanics. Self and external evaluation of perceived teamwork of team members (TMs) and leaders (TLs) was analyzed. Furthermore, possibilities for improvements were evaluated. A mixed‐methods analysis was performed with respect to gender and role to assess whether differences occur. Conclusions show considerable homogeneity between genders and roles and identify communication as most important point of improvement.","PeriodicalId":9912,"journal":{"name":"Chemie Ingenieur Technik","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142194024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
