[{"abstract":[{"lang":"eng","text":"Light-emitting diodes (LEDs) are becoming increasingly important across various sectors of the lighting industry and are being used more frequently. In the field of symbolic projection, research is increasingly focusing on implementing light modulation using energy-efficient, incoherent LEDs rather than lasers. Since light modulation in micro- and nano-optics is typically achieved through phase modulation, Finite-Difference Time-Domain (FDTD) simulations are employed for analysis. The objective of this article is to investigate different approaches for approximating incoherent monochromatic light sources within FDTD simulations. To this end, two approaches based on dipole sources are considered, as well as a method involving plane waves with modulated wavefronts based on Cosine–Fourier functions and a method based on the superposition of Gaussian beams. These methods are evaluated in terms of their accuracy using a two-dimensional double-slit configuration and are compared against a fully incoherent analytical reference."}],"publication":"Photonics","issue":"2","keyword":["tet_topic_opticalantenna","tet_topic_numerics","tet_topic_meta"],"type":"journal_article","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"},{"_id":"61"}],"date_created":"2026-02-02T07:18:03Z","publication_status":"published","date_updated":"2026-02-02T21:38:34Z","article_type":"original","intvolume":"        13","year":"2026","title":"Approximating Incoherent Monochromatic Light Sources in FDTD Simulations","author":[{"last_name":"Metzner","first_name":"Dominik","full_name":"Metzner, Dominik"},{"full_name":"Potthoff, Jens","last_name":"Potthoff","first_name":"Jens"},{"id":"30525","full_name":"Zentgraf, Thomas","first_name":"Thomas","orcid":"0000-0002-8662-1101","last_name":"Zentgraf"},{"full_name":"Förstner, Jens","first_name":"Jens","orcid":"0000-0001-7059-9862","last_name":"Förstner","id":"158"}],"publication_identifier":{"issn":["2304-6732"]},"doi":"10.3390/photonics13020128","article_number":"128","main_file_link":[{"open_access":"1","url":"https://www.mdpi.com/2304-6732/13/2/128"}],"language":[{"iso":"eng"}],"quality_controlled":"1","citation":{"ieee":"D.

This enhances dimensional accuracy in sparse-view computed tomography (CT). However, existing approaches offer no direct means to exploit this criterion for automatic scan-angle optimization. We propose a method that uses a virtual representation of the CT setup, including an STL surface model of the inspected part, to automatically identify taskspecific scan angles. Using elementary vector calculus, the algorithm determines projection directions that generate tangential X-rays for targeted surface segments. To support different levels of geometric complexity, we introduce two variants of the angle-selection procedure. The methods were experimentally validated on two objects with distinct absorption and geometric characteristics. For a steel gauge block, employing the minimum number of task-specific projections required for surface-data completeness substantially outperformed a conventional high-projection scan. For a geometrically more complex test object, surface-related errors were still reduced within the region of interest. The proposed approach – particularly suited for flat surface structures and not accounting for image-degrading factors other than cone-beam artifacts – shows promise for high-throughput dimensional metrology of mono-material parts.</jats:p>"}],"publication":"e-Journal of Nondestructive Testing","issue":"3","volume":31,"user_id":"93720","_id":"64129","publisher":"NDT.net GmbH & Co.

This reaction operates at very positive potentials, where the electrocatalyst is exposed to highly oxidative conditions and prone to potential-dependent transformation of the near-surface region. While substantial evidence for such surface restructuring exists, its extent and relevance for the catalyst’s activity are unclear. We address this topic for the case of Co3O4, one of the best-known electrocatalysts exhibiting surface restructuring, by studies of epitaxial (111)-ordered electrodeposited films with combined operando X-ray surface diffraction and absorption spectroscopy, electrochemical impedance spectroscopy, and electrochemical measurements on rotating disk electrodes. Comparison of the as-prepared and annealed state of the same samples, which both are stable even under long-term oxygen evolution conditions, provides clear insight into the role of surface defects. Our results show that defect-free annealed Co3O4(111) surfaces are structurally stable over a wide potential range and hydroxylate via adsorption at surface oxygen and Co sites. Potential-induced surface restructuring of the Co3O4 lattice occurs only in the presence of surface defects, leading to the formation of the well-known nanometer-thick oxyhydroxide skin layer. The presence of this skin layer promotes oxygen evolution at low overpotentials but results in higher Tafel slopes. As a result, highly ordered Co3O4(111) surfaces are more active at high current densities than defective Co3O4 surfaces that undergo surface restructuring. These results highlight that strategies for catalyst surface defect engineering need to be application-oriented.","lang":"eng"}],"publication":"ACS Catalysis","doi":"10.1021/acscatal.5c08785","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://pubs.acs.org/doi/10.1021/acscatal.5c08785"}],"article_number":"acscatal.5c08785","article_type":"original","date_updated":"2026-02-16T14:25:00Z","publication_status":"published","author":[{"full_name":"Scharf, Carl Hendric","first_name":"Carl Hendric","last_name":"Scharf"},{"last_name":"Chandraraj","first_name":"Alex","full_name":"Chandraraj, Alex"},{"last_name":"Dyk","first_name":"Konrad","full_name":"Dyk, Konrad"},{"full_name":"Stebner, Felix","last_name":"Stebner","first_name":"Felix"},{"first_name":"Sören","last_name":"Lepin","full_name":"Lepin, Sören"},{"full_name":"Tian, Jing","last_name":"Tian","first_name":"Jing"},{"full_name":"El Bergmi Byaz, Laila","last_name":"El Bergmi Byaz","first_name":"Laila"},{"last_name":"Stettner","first_name":"Jochim","full_name":"Stettner, Jochim"},{"id":"117722","last_name":"Leppin","first_name":"Christian","full_name":"Leppin, Christian"},{"last_name":"Kotova","first_name":"Anastasiia","full_name":"Kotova, Anastasiia"},{"id":"117727","first_name":"Sebastian","last_name":"Reinke","full_name":"Reinke, Sebastian"},{"id":"116779","full_name":"Linnemann, Julia","orcid":"0000-0001-6883-5424","first_name":"Julia","last_name":"Linnemann"},{"full_name":"Maroun, Fouad","last_name":"Maroun","first_name":"Fouad"},{"last_name":"Magnussen","first_name":"Olaf M.","full_name":"Magnussen, Olaf M."}],"publication_identifier":{"issn":["2155-5435","2155-5435"]},"title":"Role of Defects in Reversible Surface Restructuring and Activity of Co<sub>3</sub>O<sub>4</sub> Oxygen Evolution Electrocatalysts","year":"2026"},{"language":[{"iso":"ger"}],"title":"Zwischen Förderkonzept und Vorschrift – Eine empirische Studie zur Praxis der Förderplanung an Schulen in Nordrhein-Westfalen","year":"2026","publication_identifier":{"issn":["0513-9066"]},"author":[{"id":"95559","first_name":"Phillip","last_name":"Neumann","full_name":"Neumann, Phillip"},{"id":"70772","last_name":"Bunte","first_name":"Charline","full_name":"Bunte, Charline"},{"full_name":"Melzer, Conny","first_name":"Conny","last_name":"Melzer"}],"publication_status":"published","date_updated":"2026-02-18T08:46:36Z","article_type":"original","intvolume":"        77","file":[{"date_created":"2026-02-18T08:44:45Z","creator":"pneu","file_id":"64190","content_type":"application/pdf","relation":"main_file","date_updated":"2026-02-18T08:46:35Z","file_name":"zfh_02.2026_neumann.pdf","access_level":"open_access","file_size":871882}],"date_created":"2026-02-17T20:36:44Z","type":"journal_article","keyword":["Sonderpädagogik","Inklusion","Sonderpädagogische Förderung","Förderplanung","Förderpläne","Kooperation"],"department":[{"_id":"479"}],"issue":"2","publication":"Zeitschrift für Heilpädagogik","abstract":[{"lang":"ger","text":"Obwohl Förderpläne schon seit den 1990er Jahren umgesetzt werden, es mittlerweile recht viele Publikationen mit Beschreibungen des Konzepts Förderplanung gibt und diese in allen Bundesländern Deutschlands rechtlich für Schülerinnen und Schüler mit einem festgestellten Bedarf an sonderpädagogischer Unterstützung vorgeschrieben sind, gibt es recht wenige empirische Studien über die tatsächliche Umsetzung in der Praxis. Dieser Beitrag möchte die große Lücke schließen, indem die Praxis der Förderplanung an Allgemeinen Schulen und an Förderschulen in Form einer digitalen Befragung in NRW in den Blick genommen wird. Insbesondere die Frage, wie und in welcher Form Förderpläne erstellt, umgesetzt, evaluiert und fortgeschrieben werden, steht im Mittelpunkt dieser Studie. Zentrale Ergebnisse zeigen, dass Förderpläne zwar i.d.R. aufgrund der rechtlichen Vorschrift erstellt werden, aber auch für die Strukturierung des Förderprozesses fachlich-inhaltlich genutzt werden. Hierbei wird deutlich, dass von den Allgemeinen Schulen eher die Grundschulen Förderpläne auch im weiteren fachlichen Sinn nutzen. Es wird aber auch deutlich, dass einige der befragten Schulen Förderpläne gezielt nutzen, um ein Feststellungsverfahren zu eröffnen und Ressourcen zu generieren und Förderpläne damit auch defizitorientierter schreiben als im Falle der fachlichen und inhaltlichen Strukturierung von Förderprozessen."}],"page":"61-74","_id":"64189","user_id":"95559","ddc":["370"],"volume":77,"status":"public","has_accepted_license":"1","oa":"1","file_date_updated":"2026-02-18T08:46:35Z","citation":{"short":"P.

One of the most censored protocols is DNS: censors target unencrypted and encrypted DNS to prevent clients from resolving the domain name of unwanted websites. Despite much research on DNS censorship, only a few tools can circumvent it.To support users affected by DNS censorship, we present DPYProxy-DNS, a DNS resolver that automatically detects and employs a working DNS censorship circumvention. We demonstrate the effectiveness of DPYProxy-DNS by automatically circumventing DNS censorship in China and Iran and analyzing DNS censorship mechanisms in these countries. Our analyses re veal that DNS censorship in Iran is ineffective against encrypted DNS. In China, DPYProxy-DNS revealed two consistently working circumvention techniques for unencrypted DNS: TCP segmentation for DNS over TCP and ignoring DNS responses injected by the Great Firewall of China (GFW). Our findings reveal varying levels of DNS censorship across different countries, underscoring the importance of the automated circumvention approach we provide with DPYProxy-DNS.","lang":"eng"}],"file":[{"relation":"main_file","date_updated":"2026-02-21T10:20:16Z","file_name":"foci-2026-0001.pdf","access_level":"open_access","file_size":775133,"file_id":"64568","content_type":"application/pdf","creator":"nniklas","date_created":"2026-02-20T14:34:05Z"}],"date_created":"2026-02-20T14:35:34Z","type":"conference","oa":"1"},{"status":"public","year":"2026","title":"New Quick And Easy Publication - Will be edited by LibreCat team","author":[{"id":"98419","last_name":"Massopo","first_name":"Orlando","full_name":"Orlando Massopo"}],"date_updated":"2026-02-25T07:47:24Z","has_accepted_license":1,"_id":"63831","user_id":"98419","file_date_updated":"2026-02-02T11:43:49Z","publication":"Quick And Easy Journal Title","citation":{"mla":"Massopo, Orlando. “New Quick And Easy Publication - Will Be Edited by LibreCat Team.” <i>Quick And Easy Journal Title</i>, 2026.","bibtex":"@article{Massopo_2026, title={New Quick And Easy Publication - Will be edited by LibreCat team}, journal={Quick And Easy Journal Title}, author={Massopo, Orlando}, year={2026} }","ama":"Massopo O.

Basketball passing movements with and without head fakes were examined in a reaction-time paradigm. Participants were generally instructed to initiate the movement as fast and accurately as possible, while try-harder instructions were presented in 25 % of trials, prompting participants to mobilize all their cognitive resources to perform even faster. To investigate if athletic expertise modulates the potential effects of effort mobilization, basketball novices and experienced players were tested. Results demonstrated that try-harder instructions generally improved participants’ performance, facilitating faster response initiation times and movement execution, as well as a specific reduction in initiation time variability. Novices benefited more than experienced players, indicating that effort results in greater improvement when complex motor actions (for example, passes with head fakes) are not yet fully stabilized and lack automated fluency. This pattern suggests that effort enhances performance in complex actions when performance is limited by the amount of cognitive capacity available, supporting the coordination of partly conflicting movement components within tight temporal constraints. The findings extend previous research on effort mobilization from simple to complex motor tasks. Try-harder instructions appear to enhance performance primarily by reducing attentional lapses rather than generally improving processing speed. Future research should investigate the effectiveness of effort mobilization in experienced athletes in situations of high concurrent cognitive load."}],"date_created":"2026-03-05T16:55:30Z","type":"journal_article","keyword":["Effort","Try-harder instruction","Deception","Basketball","Head fake","Fake production"],"department":[{"_id":"17"},{"_id":"266"}]},{"status":"public","editor":[{"full_name":"Vogelsang, Christoph","last_name":"Vogelsang","first_name":"Christoph"},{"last_name":"Grotegut","first_name":"Lea","full_name":"Grotegut, Lea"},{"last_name":"Bruns","first_name":"Julia","full_name":"Bruns, Julia"},{"full_name":"Riese, Josef","first_name":"Josef","last_name":"Riese"},{"full_name":"Fechner, Sabine","last_name":"Fechner","first_name":"Sabine"}],"volume":2,"user_id":"82257","_id":"60342","publisher":"Waxmann","project":[{"_id":"1042","name":"DemoKult: DemoKult – Die unterrichtsbezogene Förderung von Kompetenzen für eine demokratische Kultur"}],"quality_controlled":"1","citation":{"mla":"Wehde, Janis, et al. “Das Verhältnis zwischen politischer Involviertheit und professioneller Handlungskompetenz zur unterrichtlichen Gestaltung demokratischer Lerngelegenheiten.” <i>Handlungsorientierung in der Ausbildung von Lehrkräften und pädagogischen Fachkräften - Konzeptionen, Herausforderungen &#38; Forschungsperspektiven</i>, edited by Christoph Vogelsang et al., vol. 2, Waxmann, 2026, doi:<a href=\"https://doi.org/10.31244/9783818851057\">10.31244/9783818851057</a>.","apa":"Wehde, J., Bloh, B., &#38; Homt, M.

So far, investigations involving intimate covalent or ionic bonds have not been a focus. Yet, we show here that an established technique, involving thermocompressional wafer bonding, works well for creating twisted non-van der Waals interfaces. We have successfully bonded z-cut lithium niobate single crystals to create ferroelectric oxide interfaces with strong polar discontinuities and have mapped the associated emergent interfacial conductivity. In some instances, a dramatic change in microstructure occurs, involving local dipolar switching. A twist-induced collapse in the capability of the system to effec8tively screen interfacial bound charge is implied. Importantly, this only occurs around specific moiré twist angles with sparse coincident lattices and associated short-range aperiodicity. In quasicrystals, aperiodicity is known to induce pseudo-bandgaps and we suspect a similar phenomenon here.","lang":"eng"}],"issue":"1","publication":"Nature Communications"},{"year":"2026","title":"Integrating an Organocatalyst into a Polymeric Gel Framework for the Continuous Microflow Baylis–Hillman Reaction","publication_identifier":{"issn":["2470-1343","2470-1343"]},"author":[{"full_name":"Killi, Naresh","first_name":"Naresh","last_name":"Killi"},{"first_name":"Amit","last_name":"Kumar","full_name":"Kumar, Amit"},{"full_name":"Nebhani, Leena","first_name":"Leena","last_name":"Nebhani"},{"last_name":"Obst","first_name":"Franziska","full_name":"Obst, Franziska"},{"full_name":"Richter, Andreas","last_name":"Richter","first_name":"Andreas"},{"full_name":"Reineke Matsudo, Bernhard","first_name":"Bernhard","last_name":"Reineke Matsudo"},{"full_name":"Zentgraf, Thomas","orcid":"0000-0002-8662-1101","first_name":"Thomas","last_name":"Zentgraf","id":"30525"},{"full_name":"Kuckling, Dirk","first_name":"Dirk","last_name":"Kuckling","id":"287"}],"date_updated":"2026-03-10T08:27:15Z","publication_status":"published","intvolume":"        11","article_type":"original","main_file_link":[{"open_access":"1","url":"https://pubs.acs.org/doi/abs/10.1021/acsomega.5c09476"}],"article_number":"14448","language":[{"iso":"eng"}],"doi":"10.1021/acsomega.5c09476","publication":"ACS Omega","issue":"9","abstract":[{"text":"Continuous flow catalysis utilizing gel-bound organocatalysts within a microfluidic reactor represents a compelling strategy in the realm of organic synthesis. In this study, a quinuclidine-based catalytic monomer (QMA) was synthesized to create polymer gel dots through the process of photopolymerization that serve as a support for the catalyst. The resulting gel-bound organocatalysts were assembled within a continuous microfluidic reactor to facilitate the Baylis–Hillman reaction between various aldehydes and acrylonitrile at a temperature of 50 °C. The conversion of the product was assessed using 1H NMR spectroscopy as an offline analytical method over a duration of 8 h. The findings indicated that highly reactive aldehydes achieved conversion rates exceeding 90%, in contrast to their less reactive counterparts. Furthermore, these results were juxtaposed with previously published data derived from alternative synthetic methodologies, revealing that the continuous microfluidic reactions employing integrated organocatalysts within polymer networks exhibited significantly higher conversions with reduced reaction times (8 h) at the same temperature (50 °C). Additionally, the influence of different geometries (round, triangular, and square) of the gel dots on catalytic activity was investigated, with round and square gel dots demonstrating slightly superior performance compared with triangular gel dots, attributed to their increased surface area. Moreover, an extended reaction period of 6 days was conducted using 4-bromobenzaldehyde and acrylonitrile, resulting in a conversion rate exceeding 70%, which remained stable for 5 days before experiencing a slight decline due to product accumulation on the gel dots.","lang":"eng"}],"date_created":"2026-03-10T08:23:43Z","type":"journal_article","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"},{"_id":"2"},{"_id":"311"}],"status":"public","_id":"64873","publisher":"American Chemical Society (ACS)","user_id":"30525","volume":11,"citation":{"mla":"Killi, Naresh, et al. “Integrating an Organocatalyst into a Polymeric Gel Framework for the Continuous Microflow Baylis–Hillman Reaction.” <i>ACS Omega</i>, vol. 11, no. 9, 14448, American Chemical Society (ACS), 2026, doi:<a href=\"https://doi.org/10.1021/acsomega.5c09476\">10.1021/acsomega.5c09476</a>.","bibtex":"@article{Killi_Kumar_Nebhani_Obst_Richter_Reineke Matsudo_Zentgraf_Kuckling_2026, title={Integrating an Organocatalyst into a Polymeric Gel Framework for the Continuous Microflow Baylis–Hillman Reaction}, volume={11}, DOI={<a href=\"https://doi.org/10.1021/acsomega.5c09476\">10.1021/acsomega.5c09476</a>}, number={914448}, journal={ACS Omega}, publisher={American Chemical Society (ACS)}, author={Killi, Naresh and Kumar, Amit and Nebhani, Leena and Obst, Franziska and Richter, Andreas and Reineke Matsudo, Bernhard and Zentgraf, Thomas and Kuckling, Dirk}, year={2026} }","ama":"Killi N, Kumar A, Nebhani L, et al.

Extensive research has been conducted to enhance the multiplexing capacity for diverse wavefronts. However, the independence of multiplexed channels is fundamentally restricted in techniques using single‐layer metasurfaces, resulting in unavoidable crosstalk and the need for post‐filtering of the output wavefronts. Here, a universal wavefront multiplexing concept is presented based on non‐injective transformation. By employing joint optimization on two metasurfaces, different channels can be independently designed without any constraints on the output wavefronts. To validate this approach, ultra‐compact orbital angular momentum (OAM) sorters are designed. In these experiments, the output beams from different channels can be independently mapped to 2D positions with high fineness. In another application of wavefront‐multiplexed holography, 10‐channel multiplexing is experimentally achieved with minimal crosstalk and without the need for post‐processing. These results demonstrate the independence between channels enabled by the non‐injective transformation in the method. The precise wavefront control and high multiplexing capacity underscore its potential for scalable wavefront manipulation devices.","lang":"eng"}]},{"conference":{"name":"3rd TRR 318 Conference"},"author":[{"last_name":"Buhl","first_name":"Heike M.","full_name":"Buhl, Heike M.","id":"27152"},{"id":"56345","first_name":"Josephine Beryl","last_name":"Fisher","orcid":"0000-0002-9997-9241","full_name":"Fisher, Josephine Beryl"},{"first_name":"Katharina J.","last_name":"Rohlfing","orcid":"0000-0002-5676-8233","full_name":"Rohlfing, Katharina J.","id":"50352"}],"year":"2026","title":"Cognitive and Interactive Adaptivity to the Explainee in an Explanatory Dialogue: An Experimental Study","status":"public","date_updated":"2026-03-10T08:29:56Z","language":[{"iso":"eng"}],"_id":"64872","publisher":"Bielefeld University Press","main_file_link":[{"open_access":"1"}],"editor":[{"last_name":"Cimiano","first_name":"Philipp","full_name":"Cimiano, Philipp"},{"first_name":"Benjamin","last_name":"Paassen","full_name":"Paassen, Benjamin"},{"first_name":"Anna-Lisa","last_name":"Vollmer","full_name":"Vollmer, Anna-Lisa"}],"doi":"10.64136/gumb4700","user_id":"90826","citation":{"bibtex":"@inproceedings{Buhl_Fisher_Rohlfing_2026, title={Cognitive and Interactive Adaptivity to the Explainee in an Explanatory Dialogue: An Experimental Study}, DOI={<a href=\"https://doi.org/10.64136/gumb4700\">10.64136/gumb4700</a>}, booktitle={Proceedings of the 3rd TRR 318 Conference: Contextualizing Explanations}, publisher={Bielefeld University Press}, author={Buhl, Heike M. and Fisher, Josephine Beryl and Rohlfing, Katharina J.}, editor={Cimiano, Philipp and Paassen, Benjamin and Vollmer, Anna-Lisa}, year={2026} }","ama":"Buhl HM, Fisher JB, Rohlfing KJ.

However, the environmental instability of dsRNA presents a major limitation to its field application. In this study, we evaluate two distinct dsRNA formulation strategies for improved stability and delivery: a bottom-up approach using chitosan-based interpolyelectrolyte complexes (IPEC) and a top-down approach employing functionalized mesoporous silica carriers (SBA-15). Both systems were comprehensively characterized in terms of size, surface potential, porosity, and release behavior. The results revealed that IPECs exhibited release kinetics that were approximately one order of magnitude faster than those of SBA-15 across all tested conditions. The two formulations significantly improved dsRNA stability against UV and heat exposure compared to free dsRNA. In feeding assays with P. chrysocephala, both carriers achieved comparable gene silencing efficacy, though dsRNA@IPEC induced more immediate effects, while dsRNA@SBA-15 displayed delayed but ultimately stronger reduction in consumed leaf area, consistent with its slower release kinetics. We demonstrate that despite structural and mechanistic differences, both delivery platforms effectively stabilized and delivered dsRNA, and offered distinct advantages depending on application needs. This work highlights how formulation strategies are key to successful SIGS and supports the development of robust, field-adaptable formulation technologies for sustainable pest management."}],"main_file_link":[{"open_access":"1"}],"article_number":"149697","language":[{"iso":"eng"}],"doi":"10.1016/j.ijbiomac.2025.149697","year":"2026","title":"DsRNA-based carriers with pH-tuneable release kinetics for effective control of Psylliodes chrysocephala","publication_identifier":{"issn":["0141-8130"]},"author":[{"full_name":"Moorlach, Benjamin W.","last_name":"Moorlach","first_name":"Benjamin W."},{"last_name":"Epkenhans","first_name":"Robert","full_name":"Epkenhans, Robert"},{"last_name":"Ju","first_name":"Di","full_name":"Ju, Di"},{"first_name":"Banuja","last_name":"Ravidas","full_name":"Ravidas, Banuja"},{"id":"11848","last_name":"Weinberger","first_name":"Christian","full_name":"Weinberger, Christian"},{"id":"23547","full_name":"Tiemann, Michael","last_name":"Tiemann","first_name":"Michael","orcid":"0000-0003-1711-2722"},{"full_name":"Buente, Judith","last_name":"Buente","first_name":"Judith"},{"last_name":"Gaerner","first_name":"Maik","full_name":"Gaerner, Maik"},{"last_name":"Wortmann","first_name":"Martin","full_name":"Wortmann, Martin"},{"full_name":"Scholten, Stefan","last_name":"Scholten","first_name":"Stefan"},{"last_name":"Rostas","first_name":"Michael","full_name":"Rostas, Michael"},{"full_name":"Keil, Waldemar","last_name":"Keil","first_name":"Waldemar"},{"full_name":"Patel, Anant V.","last_name":"Patel","first_name":"Anant V."}],"date_updated":"2025-12-17T07:27:57Z","publication_status":"published","intvolume":"       338","article_type":"original"},{"year":"2026","title":"Process window expansion with transferable applicability in three-layer dissimilar steel resistance spot welding via expulsion prevention","author":[{"orcid":"0000-0001-9201-9304","last_name":"Yang","first_name":"Keke","full_name":"Yang, Keke","id":"65085"},{"id":"51255","first_name":"Leonhard","last_name":"Männer","full_name":"Männer, Leonhard"},{"full_name":"Wang, Zhuoqun","last_name":"Wang","first_name":"Zhuoqun"},{"last_name":"Olfert","first_name":"Viktoria","full_name":"Olfert, Viktoria","id":"5974"},{"first_name":"Yannic","last_name":"Böhm","full_name":"Böhm, Yannic","id":"84119"},{"id":"7728","full_name":"Hein, David","last_name":"Hein","first_name":"David"},{"id":"32056","full_name":"Meschut, Gerson","last_name":"Meschut","first_name":"Gerson","orcid":"0000-0002-2763-1246"}],"publication_identifier":{"issn":["1526-6125"]},"publication_status":"published","date_updated":"2025-12-22T08:24:19Z","article_type":"original","intvolume":"       157","main_file_link":[{"url":"https://doi.org/10.1016/j.jmapro.2025.12.036","open_access":"1"}],"language":[{"iso":"eng"}],"doi":"10.1016/j.jmapro.2025.12.036","issue":"Special issue entitled: ‘Trends on spot joining’ published in Journal of Manufacturing Processes.","publication":"Journal of Manufacturing Processes","abstract":[{"text":"This study addresses the challenge of insufficient weld penetration in the outer thin low-carbon steel during\r\nresistance spot welding of three-layer dissimilar stack-ups containing advanced high-strength steels.

It increases the maximum expulsion-free heat input by\r\n24 % (to 6338 J) under normal conditions and by 77 % (to 6482 J) under the IG condition. Crucially, the\r\nincreased heat input drives nugget growth across all interfaces, achieving a penetration depth of 0.38 mm (48 %\r\npenetration ratio) in the low-carbon steel sheet under the gap condition.
