The potential of public transport and new mobility services to reduce transport-related greenhouse gas emissions cannot yet be fully exploited, especially in rural regions. This paper presents the concept of an innovative mobility system, called NeMo.bil, that intends to fill the gap between individual and public transport to create a demand-oriented and sustainable mobility offer. The concept is based on convoy formation of autonomously driving lightweight vehicles serving the first and last mile and a larger towing vehicle carrying enough power and energy to move the convoy over longer distances at higher speeds. This combination of two different vehicles, intelligently controlled by a digital ecosystem, aims to significantly increasing energy, resource and cost efficiency. Based on an analysis of previous approaches for innovative mobility solutions, the concept is derived from a technical and sociological perspective and its potential for reducing energy demand is calculated.","lang":"eng"}],"date_created":"2023-05-05T07:19:14Z","type":"book_chapter","department":[{"_id":"9"},{"_id":"321"},{"_id":"149"}]},{"_id":"36839","language":[{"iso":"eng"}],"user_id":"54897","status":"public","year":"2023","title":"Mechanically Joined Extrusion Profiles for Battery Trays","author":[{"id":"54897","full_name":"Neumann, Stefan","last_name":"Neumann","first_name":"Stefan"},{"id":"32056","last_name":"Meschut","orcid":"0000-0002-2763-1246","first_name":"Gerson","full_name":"Meschut, Gerson"},{"id":"71269","full_name":"Otroshi, Mortaza","first_name":"Mortaza","orcid":"0000-0002-8652-9209","last_name":"Otroshi"},{"last_name":"Kneuper","first_name":"Florian","full_name":"Kneuper, Florian"},{"last_name":"Schulze","first_name":"Andre","full_name":"Schulze, Andre"},{"full_name":"Tekkaya, Erman","last_name":"Tekkaya","first_name":"Erman"}],"publication_status":"submitted","date_updated":"2023-01-17T13:24:19Z","date_created":"2023-01-14T14:38:24Z","type":"conference","department":[{"_id":"157"}],"citation":{"chicago":"Neumann, Stefan, Gerson Meschut, Mortaza Otroshi, Florian Kneuper, Andre Schulze, and Erman Tekkaya. “Mechanically Joined Extrusion Profiles for Battery Trays,” n.d.","short":"S.

Additive manufacturing processes, in particular powder-based selective laser melting, are used to produce metallic additive manufactured components for the automotive and aerospace industries. Different materials are often joined together to realize sustainable lightweight construction. The production of such mixed construction joints is often realized using mechanical joining technology (e.g. self-piercing riveting). However, there is currently very little experience with the mechanical joining of metallic additive manufacturing components. Furthermore, there is insufficient knowledge about the effects that occur during the mechanical joining of additive manufacturing components. In this article, a method is presented to investigate the joinability of additively manufactured components with conventionally manufactured components using a numerical simulation of the self-piercing riveting process. For this purpose, the additive manufacturing materials are characterized experimentally, the simulation model is configured, and the joining process with additive manufacturing materials is represented in the numerical simulation. Furthermore, the influence of the building direction on the mechanical properties is shown using miniature tensile specimens. Besides the configuration of the simulation model, the influence of heat treatment on the self-piercing riveting process is presented. </jats:p>"}]},{"user_id":"59070","doi":"10.1080/00218464.2023.2178909","page":"1-31","_id":"42872","publisher":"Informa UK Limited","language":[{"iso":"eng"}],"publication_status":"published","date_updated":"2023-03-08T16:41:32Z","article_type":"original","status":"public","year":"2023","title":"Experimental and numerical investigation of the damping properties of adhesively bonded tubular steel joints","author":[{"first_name":"Johannes","last_name":"Göddecke","full_name":"Göddecke, Johannes","id":"59070"},{"first_name":"Gerson","last_name":"Meschut","orcid":"0000-0002-2763-1246","full_name":"Meschut, Gerson","id":"32056"},{"full_name":"Damm, Jannis","first_name":"Jannis","last_name":"Damm"},{"first_name":"Matthias","last_name":"Albiez","full_name":"Albiez, Matthias"},{"full_name":"Ummenhofer, Thomas","last_name":"Ummenhofer","first_name":"Thomas"},{"first_name":"Fabian","last_name":"Kötz","full_name":"Kötz, Fabian"},{"last_name":"Matzenmiller","first_name":"Anton","full_name":"Matzenmiller, Anton"}],"publication_identifier":{"issn":["0021-8464","1545-5823"]},"type":"journal_article","department":[{"_id":"157"}],"date_created":"2023-03-08T16:36:35Z","quality_controlled":"1","publication":"The Journal of Adhesion","citation":{"ieee":"J.

However, three-dimensional metasurfaces with the potential to provide additional light–matter manipulation flexibility attract only little interest. Here, we demonstrate a three-dimensional metasurface scheme capable of providing dual phase control through out-of-plane plasmonic resonance of L-shape antennas. Under circularly polarized excitation at a specific wavelength, the L-shape antennas with rotating orientation angle act as spatially variant three-dimensional tilted dipoles and are able to generate desire phase delay for different polarization components. Generalized Snell's law is achieved for both in-plane and out-of-plane dipole components through arranging such L-shape antennas into arrays. These three-dimensional metasurfaces suggest a route for wavefront modulation and a variety of nanophotonic applications."}],"date_created":"2023-04-06T06:01:06Z","type":"journal_article","keyword":["Physics and Astronomy (miscellaneous)"],"department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"title":"Three-dimensional dipole momentum analog based on L-shape metasurface","year":"2023","author":[{"first_name":"Tianyou","last_name":"Li","full_name":"Li, Tianyou"},{"first_name":"Yanjie","last_name":"Chen","full_name":"Chen, Yanjie"},{"last_name":"Wang","first_name":"Yongtian","full_name":"Wang, Yongtian"},{"full_name":"Zentgraf, Thomas","last_name":"Zentgraf","first_name":"Thomas","orcid":"0000-0002-8662-1101","id":"30525"},{"full_name":"Huang, Lingling","last_name":"Huang","first_name":"Lingling"}],"publication_identifier":{"issn":["0003-6951","1077-3118"]},"date_updated":"2023-04-06T06:02:58Z","publication_status":"published","intvolume":"       122","article_type":"original","article_number":"141702","language":[{"iso":"eng"}],"doi":"10.1063/5.0142389","citation":{"mla":"Li, Tianyou, et al. “Three-Dimensional Dipole Momentum Analog Based on L-Shape Metasurface.” <i>Applied Physics Letters</i>, vol. 122, no. 14, 141702, AIP Publishing, 2023, doi:<a href=\"https://doi.org/10.1063/5.0142389\">10.1063/5.0142389</a>.","ama":"Li T, Chen Y, Wang Y, Zentgraf T, Huang L.

The production of lightweight materials is usually associated with an increase in energy demand, so the environmental impacts of lightweight structures need to be assessed holistically using a life cycle assessment. To estimate the life cycle environmental impacts of a product in its developmental stage, for example, by life cycle engineering, future changes in relevant influencing factors must be considered. Prospective life cycle assessment provides methods for integrating future scenarios into life cycle assessment studies. However, approaches for integrating prospective life cycle assessment into product development are limited. The objective of this work is to provide the methodological foundation for integrating future scenarios of relevant influencing factors in the development of lightweight structures. The applicability of the novel methodology is demonstrated by a case study of a structural component in a steel, aluminium, and hybrid design. The results show that appropriate decarbonisation measures can reduce the life cycle greenhouse gas emissions by up to 95 percent until 2050. We also found that shifts in the environmentally optimal design are possible in future scenarios.

In order to reduce global energy consumption in production and industry along with the associated CO2 emissions, existing resources must be used more efficiently. This includes the energy-efficient and comprehensive recycling of a wide range of metals. Especially for the production of aluminium, there is a large potential for saving energy using efficient recycling processes. With regard to the recycling of aluminium studies have shown that solid-state recycling processes are significantly more efficient considering the used energy and resources compared to the conventional, smelting-metallurgical recycling process. In this paper, the direct and energy-efficient friction-induced recycling process (FIRP) based on the conform process is further described and analysed in terms of the temperature-property relationships. For this purpose, the influence of the processing temperature on the microstructure and properties of the recycled semi-finished products is investigated using the toll system that enables an ECAP forming. Specific sections of the (in theory) infinite, recycled semi-finished product are taken and analysed at different process temperatures of the solid state recycling process. Based on these sections, the properties in terms of mechanical hardness, strength, ductility and grain size are analysed and a degressive relationship between process temperature and mechanical hardness up to a temperature of 270 °C can be shown. Applying the Hall-Petch relationship, it is analysed whether there is a correlation between the strength and the microstructure in the form of the grain size. </jats:p>","lang":"eng"}],"publication":"Materials Research Proceedings","user_id":"83141","_id":"44036","publisher":"Materials Research Forum LLC","conference":{"location":"Kraków","name":"ESAFORM 2023"},"status":"public","quality_controlled":"1","citation":{"mla":"Borgert, Thomas, and Werner Homberg. “Analysis of Temperature Effect on Strength and Microstructure in Friction Induced Recycling Process (FIRP).” <i>Materials Research Proceedings</i>, Materials Research Forum LLC, 2023, doi:<a href=\"https://doi.org/10.21741/9781644902479-211\">10.21741/9781644902479-211</a>.","bibtex":"@inproceedings{Borgert_Homberg_2023, title={Analysis of temperature effect on strength and microstructure in friction induced recycling process (FIRP)}, DOI={<a href=\"https://doi.org/10.21741/9781644902479-211\">10.21741/9781644902479-211</a>}, booktitle={Materials Research Proceedings}, publisher={Materials Research Forum LLC}, author={Borgert, Thomas and Homberg, Werner}, year={2023} }","ama":"Borgert T, Homberg W.

In dieser Arbeit wird der Zusammenhang von Totvolumen, Druckverlust und Wärmerückgewinnung untersucht und Empfehlungen für den Betrieb von Rekuperatoren am isobaren Expansionsmotor gegeben."}],"publication":"Chemie Ingenieur Technik","issue":"5","type":"journal_article","keyword":["Isobarer Expansionsmotor","Dynamische Wärmeübertragungsmodellierung","Phasenwechsel","dichte Arbeitsmedien"],"department":[{"_id":"9"},{"_id":"145"}],"date_created":"2023-02-22T06:35:52Z"},{"user_id":"44759","doi":"10.1080/00218464.2023.2195556","language":[{"iso":"eng"}],"_id":"43130","publisher":"Taylor & Francis","article_type":"review","publication_status":"published","date_updated":"2023-04-27T09:01:15Z","author":[{"first_name":"Tobias","last_name":"Schmolke","full_name":"Schmolke, Tobias","id":"44759"},{"id":"537","first_name":"Dominik","last_name":"Teutenberg","full_name":"Teutenberg, Dominik"},{"id":"32056","first_name":"Gerson","last_name":"Meschut","orcid":"0000-0002-2763-1246","full_name":"Meschut, Gerson"}],"title":"Investigation of the leak tightness of structural adhesive joints for use in battery housings considering mechanical and corrosive loads","status":"public","year":"2023","department":[{"_id":"157"}],"type":"journal_article","date_created":"2023-03-28T12:01:34Z","quality_controlled":"1","citation":{"ama":"Schmolke T, Teutenberg D, Meschut G.

Typically, only the minimum distance between the measuring surfaces is used for further calculation, implying that no flow occurs between the structural elements. But this assumption is misleading, and a gap correction is necessary.

Therefore, a correction value can be determined with only minute deviations in different Newtonian fluids. As the conducted laboratory measurements are very time-consuming and expensive, a CFD-approach with only very small deviations was additionally developed and compared for validation purposes. Therefore, simulation is an effective and resource-efficient alternative to the presented laboratory measurements to determine <jats:inline-formula><jats:alternatives><jats:tex-math>$$\\Delta r$$</jats:tex-math><mml:math xmlns:mml=\"http://www.w3.org/1998/Math/MathML\">\r\n                <mml:mrow>\r\n                  <mml:mi>Δ</mml:mi>\r\n                  <mml:mi>r</mml:mi>\r\n                </mml:mrow>\r\n              </mml:math></jats:alternatives></jats:inline-formula> for the correction of structured coaxial geometries even for non-Newtonian fluids in the future.</jats:p>"}],"language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://link.springer.com/article/10.1007/s00397-023-01383-2"}],"doi":"10.1007/s00397-023-01383-2","author":[{"id":"38243","last_name":"Josch","first_name":"Sebastian","full_name":"Josch, Sebastian"},{"full_name":"Jesinghausen, Steffen","orcid":"https://orcid.org/0000-0003-2611-5298","first_name":"Steffen","last_name":"Jesinghausen","id":"3959"},{"last_name":"Dechert","first_name":"Christopher","full_name":"Dechert, Christopher","id":"69828"},{"id":"464","first_name":"Hans-Joachim","last_name":"Schmid","orcid":"000-0001-8590-1921","full_name":"Schmid, Hans-Joachim"}],"publication_identifier":{"issn":["0035-4511","1435-1528"]},"year":"2023","title":"Experimental and simulative determination and correction of the effective gap extension in structured coaxial measuring systems","article_type":"original","date_updated":"2023-03-14T07:41:28Z","publication_status":"published","oa":"1","citation":{"ieee":"S.
