As the mobility sector is a major contributor to CO<jats:sub>2</jats:sub>, various strategies are being pursued to achieve the climate targets set. An increasingly applied lightweight design method is the use of multi-material constructions. To join these structures, mechanical joining technologies such as self-pierce riveting are being used. As a result of the currently rigid tool systems, which cannot react to changing boundary conditions, a large number of rivet–die combinations is required to join the rising number of materials as well as material thickness combinations. Thus, new, versatile joining technologies are needed that can react to the described changes. The versatile self-piercing riveting (V-SPR) process is one possible approach. In this process, different material thicknesses can be joined by using a multi-range capable rivet which is set by a joining system with extended actuator technology. In this study, the V-SPR joining process is analysed numerically according to the influence of the geometrical rivet parameters on the joints characteristics as well as the resulting material flow. The investigations showed that the shank geometry has a decisive influence on the expansion of the rivet. Furthermore, the rivet length could be proven to be an influencing factor. By changing the head radii and the protrusion height, the forming behaviour of the rivet head onto the punch-sided joining part could be improved and thus the formation of air pockets was prevented. Based on the numerical investigations, a novel rivet geometry was developed and produced by machining. Subsequently, experimentally produced joints were analysed according to their joint formation and load-bearing capacity."}],"publication":"Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical Engineering","doi":"10.1177/09544089241263141","article_number":"09544089241263141","language":[{"iso":"eng"}],"date_updated":"2025-09-23T13:15:51Z","publication_status":"published","year":"2024","title":"Investigation of the influence of the rivet geometry on joint formation for a versatile self-piercing riveting process","publication_identifier":{"issn":["0954-4089","2041-3009"]},"author":[{"first_name":"Fabian","last_name":"Kappe","full_name":"Kappe, Fabian","id":"66459"},{"id":"7850","full_name":"Bobbert, Mathias","first_name":"Mathias","last_name":"Bobbert"},{"first_name":"Gerson","last_name":"Meschut","orcid":"0000-0002-2763-1246","full_name":"Meschut, Gerson","id":"32056"}]},{"date_created":"2025-09-23T13:16:12Z","type":"journal_article","citation":{"ama":"Wituschek S, Elbel L, Lechner M.

One of the most important popular methods is the use of multi-material systems. Due to the different geometric and mechanical properties of the various materials used, resource efficient applications and utilizations are possible. Great challenges arise for the joining processes to realize these multi-material systems, since conventional joining processes reach their limits. In the field of mechanical joining processes, there are continuously new approaches, such as superimposing the punch in a self-piercing riveting process with a tumbling kinematic, to increase the number of adaptable process parameters and enhance the process control. Through various preliminary tests, a good understanding of the process has been developed, which allows to directly control the geometric joint parameters by configuring the tumbling strategy. A major challenge, particularly with regard to future industrial applications, is the process time, which is comparatively high due to the tumbling kinematics. In the investigations, a reduction of approximately 90% of the process time is targeted by adapting the joining and tumbling strategy. Therefore, the correlation of the traverse velocity and the tumbling velocity are examined in a gradual series of experiments. To represent realistic applications, the experiments are carried out with a dual-phase steel and a precipitation-hardening aluminum alloy. For identifying the influence of the process parameters on the joining process, a constant rivet–die combination is applied. Further, the examination of force–displacement curves is conducted. Moreover, the determination of geometric joint parameters is reliant upon macrographs to assess the influence of the joining time on the geometric joint formation. The test results show that a significant increase in joining speed with a resulting reduction in process time is feasible. Although the joining properties are affected, reliable joining is possible. In particular, the shaft thickness of the rivet is influenced by the varying proportion of the tumbling process in the joining operation and increases with higher joining speeds.","lang":"eng"}],"quality_controlled":"1","_id":"61414","language":[{"iso":"eng"}],"publisher":"SAGE Publications","article_number":"09544089241248430","user_id":"44935","doi":"10.1177/09544089241248430","author":[{"id":"83423","full_name":"Wituschek, Simon","first_name":"Simon","last_name":"Wituschek"},{"full_name":"Elbel, Leonie","last_name":"Elbel","first_name":"Leonie"},{"full_name":"Lechner, Michael","last_name":"Lechner","first_name":"Michael"}],"publication_identifier":{"issn":["0954-4089","2041-3009"]},"title":"Influence of the process time on a self-piercing riveting process with tumbling kinematic","status":"public","year":"2024","publication_status":"published","date_updated":"2025-09-23T13:33:49Z"},{"quality_controlled":"1","abstract":[{"lang":"eng","text":"Increasing material costs, decreasing availability, and ever-higher demands on environmental compatibility and complexity require new strategies in the development and production of functional components. Consequently, a combined approach from the areas of design, material science, and manufacturing is mandatory, in order to meet the requirements. Reducing the number of parts, using lightweight materials and applying hybrid components with a multimaterial mix are possible solutions. Nevertheless, conventional joining operations like welding or riveting are reaching their limits in terms of material utilization, load-bearing capacity as well as versatility of the process. Thus, innovative and versatile joining by forming operations and process combinations are focus of current research. In this context, the innovative process of orbital forming had been investigated as a joining by forming operation to manufacture load-adapted hybrid functional components. By tilting of one tool component during the process, a radial material flow is generated, allowing the crimping of the two joining partners. Nevertheless, the load-bearing capacity in axial direction could be identified as limiting factor for a possible application. Therefore, the aim of this investigation is the development of a fundamental process understanding on the influence of a novel geometrical adaption of the joint on the resulting load bearing capacity. The influence of varying geometrical proportions of the joint on the quality is evaluated, considering the form filling, the geometrical properties of the components as well as the maximum transmittable axial load.

However, the rigid tooling systems cannot be adjusted to changing boundary conditions which is why new, versatile joining technologies are required. In the versatile self-piercing riveting (V-SPR) process presented in [1] different material combination are joined by using a multi-range capable rivet. The rivet head is formed onto the respective thickness of the joint by an outer punch. In order to punch thru the upper sheet a great rivet hardness is required whereas a lower hardness is required for the subsequent forming of the rivet head. To achieve a combination of these requirements, this study investigates a local heat treatment of the rivet. The aim is to determine the feasibility of such a heat treatment as well as to investigate the influence on the joint formation."}],"article_number":"012009","language":[{"iso":"eng"}],"doi":"10.1088/1757-899x/1307/1/012009","title":"Influence of local heat treatment of rivets on the joint formation of a versatile joining process","year":"2024","publication_identifier":{"issn":["1757-8981","1757-899X"]},"author":[{"first_name":"Fabian","last_name":"Kappe","full_name":"Kappe, Fabian","id":"66459"},{"full_name":"Bobbert, Mathias","first_name":"Mathias","last_name":"Bobbert","id":"7850"},{"id":"32056","orcid":"0000-0002-2763-1246","first_name":"Gerson","last_name":"Meschut","full_name":"Meschut, Gerson"}],"publication_status":"published","date_updated":"2025-09-23T13:34:12Z","intvolume":"      1307"},{"status":"public","conference":{"location":"Krefeld","start_date":"2024-12-05","name":"42.

However, the structural resolution in the computer tomograph depends on the object and must therefore be determined separately for each measurement task. The previous approaches to structural resolution determination are only related to test specimens. In this paper, less discrete approaches based on a circular pattern are presented, which can be integrated into the measured component. A voxel-based methodology as well as two surface-based methodologies are described. The investigation results regarding the effect of the component position on the structural resolution are obtained on the basis of real CT measurements. A comparison is also completed with the well-known hourglass method. The results show that the resolution depends on the object being measured, with similar values being obtained for the same object using different methods.</jats:p>","lang":"eng"}],"date_created":"2025-10-10T18:16:13Z","department":[{"_id":"43"}],"type":"journal_article","status":"public","_id":"61784","publisher":"MDPI AG","page":"457-468","volume":4,"user_id":"107107","citation":{"chicago":"Busch, Matthias, and Tino Hausotte. “Practical Approaches for Determining the Structural Resolution Capability of X-Ray Computed Tomography Measurement Tasks.” <i>Metrology</i> 4, no. 3 (2024): 457–68. <a href=\"https://doi.org/10.3390/metrology4030028\">https://doi.org/10.3390/metrology4030028</a>.","short":"M.

Reducing the weight of vehicles can significantly lower the energy or fuel consumed and thus the emissions during operation. One possibility to assess this is the use of a property adapted multi-material systems containing high strength steel, light metals like aluminium or magnesium and fibre reinforced plastics. While expanding the number of materials used new challenges arise for the production and furthermore the joining technology to manufacture the vehicle made of the multi-material systems. One approach to overcome these challenges is to use innovative and adaptable joining techniques which allows the manufacturing of joints of different material combinations. Extensive research activities on the two stage thermo-mechanical joining process with adaptable joining elements was able to demonstrate the great potentials in terms of joining dissimilar materials with good strength. The previously kinematic and path-based fabrication of auxiliary joining elements is modified in this publication to a form-based approach with a perspective of establishing an efficient process chain using easily and cheaply available rods. Based on the new approach to produce the auxiliary joining elements, it can be demonstrated that a reproducible production of the geometry is possible for the investigated steel as well as aluminium material. </jats:p>"}],"project":[{"name":"TRR 285 - Project Area C","_id":"133"},{"_id":"147","name":"TRR 285 - Subproject C03"},{"name":"TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten","_id":"130"}],"date_created":"2024-06-07T09:38:45Z","type":"conference","department":[{"_id":"156"}],"year":"2024","title":"Form-based manufacturing of aluminium and steel auxiliary joining elements as the basis for an efficient joining operation","status":"public","publication_identifier":{"issn":["2474-395X"]},"author":[{"id":"83141","last_name":"Borgert","first_name":"Thomas","full_name":"Borgert, Thomas"},{"id":"88725","last_name":"Nordieker","first_name":"Ansgar Bernhard","full_name":"Nordieker, Ansgar Bernhard"},{"id":"233","first_name":"Werner","last_name":"Homberg","full_name":"Homberg, Werner"}],"conference":{"name":"ESAFORM 2024","location":"Toulouse"},"publication_status":"published","date_updated":"2026-05-12T11:56:47Z","language":[{"iso":"eng"}],"_id":"54650","publisher":"Materials Research Forum LLC","user_id":"7850","doi":"10.21741/9781644903131-180"},{"publication":"Journal of Advanced Joining Processes","department":[{"_id":"156"}],"type":"journal_article","date_created":"2024-06-07T09:31:59Z","intvolume":"         9","publication_status":"published","date_updated":"2026-05-12T11:56:15Z","publication_identifier":{"issn":["2666-3309"]},"author":[{"id":"83141","full_name":"Borgert, Thomas","first_name":"Thomas","last_name":"Borgert"},{"first_name":"Ansgar Bernhard","last_name":"Nordieker","full_name":"Nordieker, Ansgar Bernhard","id":"88725"},{"first_name":"Eugen","last_name":"Wiens","full_name":"Wiens, Eugen","id":"7888"},{"last_name":"Homberg","first_name":"Werner","full_name":"Homberg, Werner","id":"233"}],"title":"Investigations to improve the tool life during thermomechanical and incremental forming of steel auxiliary joining elements","year":"2024","doi":"10.1016/j.jajp.2024.100185","language":[{"iso":"eng"}],"article_number":"100185","project":[{"name":"TRR 285 - Project Area C","_id":"133"},{"_id":"147","name":"TRR 285 - Subproject C03"},{"_id":"130","name":"TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten"}],"citation":{"bibtex":"@article{Borgert_Nordieker_Wiens_Homberg_2024, title={Investigations to improve the tool life during thermomechanical and incremental forming of steel auxiliary joining elements}, volume={9}, DOI={<a href=\"https://doi.org/10.1016/j.jajp.2024.100185\">10.1016/j.jajp.2024.100185</a>}, number={100185}, journal={Journal of Advanced Joining Processes}, publisher={Elsevier BV}, author={Borgert, Thomas and Nordieker, Ansgar Bernhard and Wiens, Eugen and Homberg, Werner}, year={2024} }","chicago":"Borgert, Thomas, Ansgar Bernhard Nordieker, Eugen Wiens, and Werner Homberg. “Investigations to Improve the Tool Life during Thermomechanical and Incremental Forming of Steel Auxiliary Joining Elements.” <i>Journal of Advanced Joining Processes</i> 9 (2024). <a href=\"https://doi.org/10.1016/j.jajp.2024.100185\">https://doi.org/10.1016/j.jajp.2024.100185</a>.","ama":"Borgert T, Nordieker AB, Wiens E, Homberg W.

For online monitoring of self-piercing riveting, envelope curves are often used to define a tolerance zone for the measured setting force. However, the measurement uncertainty is typically not considered and the force curve of a joint can be wrongly rated as non-conform due to measurement errors and noise. In this article, we present a method for dynamical online filtering and uncertainty determination for noisy force curves using two types of Bayesian filters. The methodology is based on a Bayesian probability framework using a priori information for the process curve and sensor noise. To investigate the general feasibility of the method, force measurements with different noise levels are simulated and processed. The conformity is further assessed taking the uncertainty of the filtered signal into account. The results show that the Bayes filter technique is principally able to reduce noise for well-known characteristics of the process curve and sensor noise. Advantages over common filtering techniques, especially for experimental conditions with less known characteristics, are still to be verified. The methodology could be used in future for closed-loop controls to adapt process parameters dynamically. </jats:p>"}],"publication":"Materials Research Proceedings","type":"conference","department":[{"_id":"157"}],"date_created":"2024-03-25T10:37:40Z","date_updated":"2024-03-25T10:44:19Z","publication_status":"published","title":"Dynamic conformity assessment for joining force monitoring using Bayes filters","year":"2023","publication_identifier":{"issn":["2474-395X"]},"author":[{"full_name":"Butzhammer, Lorenz","first_name":"Lorenz","last_name":"Butzhammer"},{"id":"66459","full_name":"Kappe, Fabian","first_name":"Fabian","last_name":"Kappe"},{"id":"32056","full_name":"Meschut, Gerson","first_name":"Gerson","last_name":"Meschut","orcid":"0000-0002-2763-1246"},{"first_name":"Tino ","last_name":"Hausotte","full_name":"Hausotte, Tino "}],"doi":"10.21741/9781644902417-48","main_file_link":[{"url":"https://www.mrforum.com/wp-content/uploads/open_access/9781644902417/48.pdf","open_access":"1"}],"language":[{"iso":"eng"}],"quality_controlled":"1","project":[{"grant_number":"418701707","_id":"130","name":"TRR 285: TRR 285"},{"name":"TRR 285 - C: TRR 285 - Project Area C","_id":"133"},{"_id":"146","name":"TRR 285 – C02: TRR 285 - Subproject C02"},{"_id":"149","name":"TRR 285 – C05: TRR 285 - Subproject C05"}],"citation":{"mla":"Butzhammer, Lorenz, et al. “Dynamic Conformity Assessment for Joining Force Monitoring Using Bayes Filters.” <i>Materials Research Proceedings</i>, Materials Research Forum LLC, 2023, doi:<a href=\"https://doi.org/10.21741/9781644902417-48\">10.21741/9781644902417-48</a>.","ama":"Butzhammer L, Kappe F, Meschut G, Hausotte T.

For the reduction of moving masses and the resources consumed, lightweight construction technologies are part of modern production processes in vehicle manufacturing, for example in the form of multi-material systems. Challenging in the manufacture of multi-material systems especially in view of changing supply chains is the variety of materials and geometries that bring conventional joining processes to their limits. Therefore, new processes are required, which can react versatile to process and disturbance variables. A widely used industrial joining process is semi-tubular self-piercing riveting, which is however a rigid process. To increase the versatility, the two newly established processes multi-range self-piercing riveting and tumbling self-piercing riveting are combined and the capabilities for targeted material flow control are united. Therefore, an innovative two-stage process based on the combination is introduced in this paper. The rivet is set with the multi-range self-piercing riveting process with an overlap of the rivet head and then formed by a tumbling process. Further, a specific adaptation of the tumbling strategy is used to investigate the possibility of reducing cracks in the rivet head. Thereby, different tumbling strategies are used and similar geometric joint formations are achieved to compare the results. </jats:p>","lang":"eng"}],"language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://www.mrforum.com/wp-content/uploads/open_access/9781644902417/16.pdf?"}],"doi":"10.21741/9781644902417-16","publication_identifier":{"issn":["2474-395X"]},"author":[{"first_name":"Simon","last_name":"Wituschek","full_name":"Wituschek, Simon"},{"id":"66459","last_name":"Kappe","first_name":"Fabian","full_name":"Kappe, Fabian"},{"full_name":"Meschut, Gerson","first_name":"Gerson","orcid":"0000-0002-2763-1246","last_name":"Meschut","id":"32056"},{"full_name":"Lechner, Michael","last_name":"Lechner","first_name":"Michael"}],"year":"2023","title":"Combination of versatile self-piercing riveting processes","date_updated":"2024-03-25T12:41:23Z","publication_status":"published"},{"date_created":"2023-01-13T14:37:34Z","keyword":["Electrical and Electronic Engineering","Instrumentation"],"type":"journal_article","department":[{"_id":"630"}],"issue":"1","publication":"Journal of Sensors and Sensor Systems","abstract":[{"text":"Abstract. The miniaturisation of components leads to new demands on measurement systems. One of these is the resolution. As a volumetric analysis method and method of non-destructive testing, industrial X-ray computed\r\ntomography (XCT) has the ability to measure geometrical features and their corresponding dimensions without destroying them and can therefore be used for quality assurance. However, the concept of resolution is not trivial for XCT and has not yet been finally clarified. In particular, the interface structural resolution, the detectability of two surfaces facing each other after surface segmentation, faces a lack of a test specimen, a corresponding\r\nmeasurand and a reliable method. Simulation-based XCT investigations of a method to determine this type of resolution are presented in this article using the geometry of a test specimen that contains several radially\r\narranged holes of the same size. The borehole diameters correspond to the distance between the holes to investigate the resolvability of surfaces and interfaces. The evaluation is based on mean and extreme values of grey value\r\nprofiles between the individual boreholes of the reconstructed volume. It is shown that the geometrical detectability of the test specimen surface and interface can be extended by a reasonable choice of the threshold value for\r\nsurface segmentation within a defined interval. With regard to the resolving capability, a distinction is made between assured detectability and possible detectability, as well as the threshold value used when using the ISO50\r\nthreshold for surface segmentation and measurement chain completion.

Increasing resource efficiency is a major challenge and affects almost every aspect of social and economic life. The mobility sector in particular is responsible for a large share of primary energy consumption and is increasingly in the focus of public interest. One possibility to adress these challenges is to reduce the vehicle weight by means of lightweight construction technologies such as multi-material systems. These assemblies consist of workpieces with different mechanical and geometrical properties, which poses a major challenge for joining technology. Mechanical joining processes such as semi-tubular self-piercing riveting are often used in the production of these assemblies, but due to their process characteristics, they are rigid and can only react to changing process variables to a limited extent. One way to increase the versatility of self-piercing riveting is to superimpose a tumbling kinematics on the punch. During tumbling, an angular offset of the punch axis to the tool axis is set and the contact area between punch and workpiece is reduced. In this work, investigations were carried out to determine how the tumbling strategy, consisting of the parameters tumbling angle, tumbling onset and tumbling kinematics, affects the material flow of the rivet element. For this purpose, experimental tests are conducted with the typical materials of conventional multi-material systems and the geometric joint formations are determined by means of macrographs. </jats:p>","lang":"eng"}],"date_created":"2023-08-10T10:38:51Z","type":"conference","author":[{"full_name":"Wituschek, S.","last_name":"Wituschek","first_name":"S."},{"full_name":"Elbel, L.","first_name":"L.","last_name":"Elbel"},{"first_name":"M.","last_name":"Lechner","full_name":"Lechner, M."}],"publication_identifier":{"issn":["2474-395X"]},"status":"public","title":"Versatile self-piercing riveting with a tumbling superimposed punch","year":"2023","date_updated":"2023-08-10T10:41:41Z","publication_status":"published","_id":"46476","language":[{"iso":"eng"}],"publisher":"Materials Research Forum LLC","doi":"10.21741/9781644902479-122","user_id":"83423"},{"project":[{"_id":"130","grant_number":"418701707","name":"TRR 285: TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten"},{"name":"TRR 285 - C: TRR 285 - Project Area C","_id":"133"},{"name":"TRR 285 – C04: TRR 285 - Subproject C04","_id":"148"}],"publication":"Lecture Notes in Production Engineering","citation":{"ama":"Reschke G, Brosius A.

Force-displacement measurements and macrosections are commonly used methods to validate numerical models of clinching processes. However, these ex-situ methods often lead to springback of elastic deformations and crack-closing after unloading. In contrast, the in-situ computed tomography (CT) can provide three-dimensional images of the clinching point under loading conditions. So far, the quantity of elastic springback that causes measuring deviations between in- and ex-situ measurements is not determined. In this paper, a method is described to quantitatively compare the results of in-situ CT, ex-situ CT and CT scans of cut specimens, which are prepared for macrosectioning, among each other. The method is applied to a single-lap shear test of two clinched aluminum sheets. Here, the test is conducted to specific process steps, then the specimen is CT scanned in-situ (during loading) and ex-situ (after unloading). Subsequently, the specimens are cut for macrosectioning and CT scanned. Finally, the outer contours and the interfaces of cross section images are determined by digital image analysis and the deviations over the clinching point between ex- and in-situ methods are calculated. </jats:p>","lang":"eng"}],"project":[{"name":"TRR 285: TRR 285","grant_number":"418701707","_id":"130"},{"_id":"133","name":"TRR 285 - C: TRR 285 - Project Area C"},{"name":"TRR 285 – C04: TRR 285 - Subproject C04","_id":"148"}],"date_created":"2024-02-06T14:48:44Z","type":"conference","department":[{"_id":"157"},{"_id":"43"}],"title":"Comparison of ex- and in-situ investigations of clinched single-lap shear specimens","status":"public","year":"2023","author":[{"last_name":"Köhler","first_name":"Daniel","full_name":"Köhler, Daniel"},{"full_name":"Kupfer, Robert","last_name":"Kupfer","first_name":"Robert"},{"full_name":"Troschitz, Juliane","first_name":"Juliane","last_name":"Troschitz"},{"first_name":"Maik","last_name":"Gude","full_name":"Gude, Maik"}],"publication_identifier":{"issn":["2474-395X"]},"date_updated":"2025-06-02T20:18:56Z","publication_status":"published","_id":"51190","language":[{"iso":"eng"}],"publisher":"Materials Research Forum LLC","doi":"10.21741/9781644902417-20","user_id":"83408"},{"type":"book_chapter","department":[{"_id":"157"},{"_id":"43"}],"place":"Cham","date_created":"2024-02-06T15:03:03Z","project":[{"_id":"130","grant_number":"418701707","name":"TRR 285: TRR 285"},{"_id":"133","name":"TRR 285 - C: TRR 285 - Project Area C"},{"name":"TRR 285 – C04: TRR 285 - Subproject C04","_id":"148"}],"publication":"Lecture Notes in Production Engineering","citation":{"ama":"Köhler D, Stephan R, Kupfer R, Troschitz J, Brosius A, Gude M.

One example of a highly adaptable process due to the two-step process sequence is thermomechanical joining with Friction Spun Joint Connectors (FSJCs) that can be individually adapted to the joint. In this paper, the potentials of the adaption in the two-stage joining process with aluminium auxiliary joining elements are investigated. To this end, it is first investigated whether a thermomechanical forming process can be used to achieve a uniform and controlled manufacturing regarding the process variable of the temperature as well as the geometry of the FSJC. Based on the successful proof of the high and good repeatability in the FSJC manufacturing, possibilities, and potentials for the targeted influencing of the process and FSJC geometry are shown, based on an extensive variation of the process input variables (delivery condition and thus mechanical properties of the raw parts as well as the process parameters of rotational speed and feed rate). Here it can be shown that above all, the feed rate of the final forming process has the strongest influence on the process and thus also offers the strongest possibilities for influencing it.</jats:p>","lang":"eng"}],"article_number":"147","language":[{"iso":"eng"}],"doi":"10.3390/jmmp7040147","year":"2023","title":"Investigations on the Influences of the Thermomechanical Manufacturing of Aluminium Auxiliary Joining Elements","publication_identifier":{"issn":["2504-4494"]},"author":[{"full_name":"Borgert, Thomas","last_name":"Borgert","first_name":"Thomas","id":"83141"},{"full_name":"Henke, Maximilian","first_name":"Maximilian","last_name":"Henke"},{"last_name":"Homberg","first_name":"Werner","full_name":"Homberg, Werner","id":"233"}],"publication_status":"published","date_updated":"2026-05-12T11:59:08Z","article_type":"original","intvolume":"         7"}]
