For a three‐steel‐sheet spot‐welded joint combining DP600 (1.5 mm)–CR1900T (1.0 mm)–CR1900T (1.0 mm), experiments under shear loading reveal that fracture occurs in the DP600 sheet along the weld nugget edge. In subsequent numerical simulation studies with damage mechanics models whose parameters are independently calibrated for every involved material configuration, three variations of the geometrical joint configuration are considered—an approximation of the real joint, one variation with a steeper weld nugget shape, and one variation with a less pronounced gradient between weld nugget material and heat‐affected zone material properties. The results of the finite‐element simulations show that a shallower weld nugget and a more pronounced material gradient lead to a faster increase of plastic strain at the edge of the weld nugget and promote the occurrence of total dome failure."}],"user_id":"5974","title":"Influences of Weld Nugget Shape and Material Gradient on the Shear Strength of Resistance Spot‐Welded Joints","publication":"steel research international","keyword":["Materials Chemistry","Metals and Alloys","Physical and Theoretical Chemistry","Condensed Matter Physics"],"department":[{"_id":"157"}],"author":[{"last_name":"Schuster","first_name":"Lilia","full_name":"Schuster, Lilia"},{"first_name":"Viktoria","full_name":"Olfert, Viktoria","last_name":"Olfert","id":"5974"},{"full_name":"Sherepenko, Oleksii","first_name":"Oleksii","last_name":"Sherepenko"},{"first_name":"Clemens","full_name":"Fehrenbach, Clemens","last_name":"Fehrenbach"},{"last_name":"Song","first_name":"Shiyuan","full_name":"Song, Shiyuan"},{"first_name":"David","full_name":"Hein, David","last_name":"Hein","id":"7728"},{"last_name":"Meschut","id":"32056","first_name":"Gerson","full_name":"Meschut, Gerson","orcid":"0000-0002-2763-1246"},{"full_name":"Biro, Elliot","first_name":"Elliot","last_name":"Biro"},{"first_name":"Sebastian","full_name":"Münstermann, Sebastian","last_name":"Münstermann"}],"publisher":"Wiley","quality_controlled":"1","date_created":"2024-01-22T09:17:07Z","status":"public","publication_identifier":{"issn":["1611-3683","1869-344X"]},"publication_status":"published"},{"article_number":"117","issue":"2","_id":"52738","intvolume":" 14","year":"2024","citation":{"mla":"Milaege, Dennis, et al. “Anisotropic Mechanical and Microstructural Properties of a Ti-6Al-7Nb Alloy for Biomedical Applications Manufactured via Laser Powder Bed Fusion.” Crystals, vol. 14, no. 2, 117, MDPI AG, 2024, doi:10.3390/cryst14020117.","bibtex":"@article{Milaege_Eschemann_Hoyer_Schaper_2024, title={Anisotropic Mechanical and Microstructural Properties of a Ti-6Al-7Nb Alloy for Biomedical Applications Manufactured via Laser Powder Bed Fusion}, volume={14}, DOI={10.3390/cryst14020117}, number={2117}, journal={Crystals}, publisher={MDPI AG}, author={Milaege, Dennis and Eschemann, Niklas and Hoyer, Kay-Peter and Schaper, Mirko}, year={2024} }","ama":"Milaege D, Eschemann N, Hoyer K-P, Schaper M.

Unfortunately, studies investigating this alloy showed that additively produced samples exhibit anisotropic microstructures. This anisotropy compromises the mechanical properties and complicates the loading state in the implant. Moreover, the minimum requirements as specified per designated standards such as ISO 5832-11 are not met. The remedy to this problem is performing a conventional heat treatment. As this route requires energy, infrastructure, labor, and expertise, which in turn mean time and money, many of the additive manufacturing benefits are negated. Thus, the goal of this work was to achieve better isotropy by applying only adapted additive manufacturing process parameters, specifically focusing on the build orientations. In this work, samples orientated in 90°, 45°, and 0° directions relative to the building platform were manufactured and tested. These tests included mechanical (tensile and fatigue tests) as well as microstructural analyses (SEM and EBSD). Subsequently, the results of these tests such as fractography were correlated with the acquired mechanical properties. These showed that 90°-aligned samples performed best under fatigue load and that all requirements specified by the standard regarding monotonic load were met."}],"volume":14,"status":"public","date_created":"2024-03-22T13:46:37Z","publisher":"MDPI AG","quality_controlled":"1","author":[{"last_name":"Milaege","id":"35461","first_name":"Dennis","full_name":"Milaege, Dennis"},{"full_name":"Eschemann, Niklas","first_name":"Niklas","last_name":"Eschemann"},{"last_name":"Hoyer","id":"48411","first_name":"Kay-Peter","full_name":"Hoyer, Kay-Peter"},{"id":"43720","last_name":"Schaper","full_name":"Schaper, Mirko","first_name":"Mirko"}],"publication":"Crystals","keyword":["Inorganic Chemistry","Condensed Matter Physics","General Materials Science","General Chemical Engineering"],"doi":"10.3390/cryst14020117","date_updated":"2024-03-22T14:22:36Z","language":[{"iso":"eng"}],"title":"Anisotropic Mechanical and Microstructural Properties of a Ti-6Al-7Nb Alloy for Biomedical Applications Manufactured via Laser Powder Bed Fusion","publication_status":"published","publication_identifier":{"issn":["2073-4352"]},"department":[{"_id":"158"},{"_id":"321"}]},{"title":"Electrochemical Removal of HF from Carbonate-based LiPF6-containing Li-ion Battery Electrolytes","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"publication_status":"published","publication_identifier":{"issn":["0013-4651","1945-7111"]},"date_updated":"2024-03-25T17:01:09Z","doi":"10.1149/1945-7111/ad30d3","oa":"1","language":[{"iso":"eng"}],"article_type":"original","abstract":[{"lang":"eng","text":"Due to the hydrolytic instability of LiPF6 in carbonate-based solvents, HF is a typical impurity in Li-ion battery electrolytes. HF significantly influences the performance of Li-ion batteries, for example by impacting the formation of the solid electrolyte interphase at the anode and by affecting transition metal dissolution at the cathode. Additionally, HF complicates studying fundamental interfacial electrochemistry of Li-ion battery electrolytes, such as direct anion reduction, because it is electrocatalytically relatively unstable, resulting in LiF passivation layers. Methods to selectively remove ppm levels of HF from LiPF6-containing carbonate-based electrolytes are limited. We introduce and benchmark a simple yet efficient electrochemical in situ method to selectively remove ppm amounts of HF from LiPF6-containing carbonate-based electrolytes. The basic idea is the application of a suitable potential to a high surface-area metallic electrode upon which only HF reacts (electrocatalytically) while all other electrolyte components are unaffected under the respective conditions."}],"user_id":"23547","author":[{"last_name":"Ge","first_name":"Xiaokun","full_name":"Ge, Xiaokun"},{"first_name":"Marten","full_name":"Huck, Marten","last_name":"Huck"},{"last_name":"Kuhlmann","first_name":"Andreas","full_name":"Kuhlmann, Andreas"},{"last_name":"Tiemann","id":"23547","first_name":"Michael","orcid":"0000-0003-1711-2722","full_name":"Tiemann, Michael"},{"last_name":"Weinberger","id":"11848","first_name":"Christian","full_name":"Weinberger, Christian"},{"last_name":"Xu","full_name":"Xu, Xiaodan","first_name":"Xiaodan"},{"last_name":"Zhao","full_name":"Zhao, Zhenyu","first_name":"Zhenyu"},{"first_name":"Hans-Georg","full_name":"Steinrueck, Hans-Georg","last_name":"Steinrueck"}],"quality_controlled":"1","publisher":"The Electrochemical Society","keyword":["Materials Chemistry","Electrochemistry","Surfaces","Coatings and Films","Condensed Matter Physics","Renewable Energy","Sustainability and the Environment","Electronic","Optical and Magnetic Materials"],"publication":"Journal of The Electrochemical Society","volume":171,"status":"public","date_created":"2024-03-08T06:27:10Z","intvolume":" 171","_id":"52372","main_file_link":[{"url":"https://dx.doi.org/10.1149/1945-7111/ad30d3","open_access":"1"}],"type":"journal_article","citation":{"short":"X.

Knowledge on the thermal conductivity of paraffins is necessary for the design and optimization of heat storage systems. However, for most paraffins solely the thermal conductivity of the liquid state has been sufficiently investigated. For the solid state, precise thermal conductivity data are only known for a few paraffins, while only generalized values are available for the remainder, some of which contradict each other. In this study, a measurement setup based on the modified guarded hot plate method is developed. It is used to investigate the thermal conductivity of several paraffines in the solid state, including pure n-docosane and its compounds with different types and concentrations of graphite. For n-docosane in the solid state, the thermal conductivity is determined to be 0.49 W/(m K). A particle size of 200 μm with a spherical shape turns out to be optimal to increase the thermal conductivity. This allows the thermal conductivity of a compound with 10% graphite to increase by a factor of three compared to the pure paraffin. Furthermore, significant differences to thermal conductivity data from the literature are found.","lang":"eng"}],"publication_status":"published","publication_identifier":{"issn":["1388-6150","1588-2926"]},"status":"public","date_created":"2023-04-04T06:48:57Z","publisher":"Springer Science and Business Media LLC","author":[{"id":"7828","last_name":"Paul","full_name":"Paul, Andreas","first_name":"Andreas"},{"id":"15164","last_name":"Baumhögger","full_name":"Baumhögger, Elmar","first_name":"Elmar"},{"id":"49826","last_name":"Dewerth","full_name":"Dewerth, Mats-Ole","first_name":"Mats-Ole"},{"first_name":"Iman","full_name":"Hami Dindar, Iman","last_name":"Hami Dindar","id":"54836"},{"last_name":"Sonnenrein","full_name":"Sonnenrein, Gerrit","first_name":"Gerrit"},{"last_name":"Vrabec","full_name":"Vrabec, Jadran","first_name":"Jadran"}],"quality_controlled":"1","publication":"Journal of Thermal Analysis and Calorimetry","department":[{"_id":"728"},{"_id":"145"},{"_id":"393"},{"_id":"9"}],"keyword":["Physical and Theoretical Chemistry","Condensed Matter Physics"]},{"language":[{"iso":"eng"}],"date_updated":"2023-04-27T11:19:08Z","oa":"1","doi":"10.1515/arh-2022-0140","department":[{"_id":"150"}],"publication_identifier":{"issn":["1617-8106"]},"publication_status":"published","title":"Development of an adaptive coaxial concrete rheometer and rheological characterisation of fresh concrete","main_file_link":[{"open_access":"1","url":"https://www.degruyter.com/document/doi/10.1515/arh-2022-0140/html"}],"year":"2023","type":"journal_article","citation":{"chicago":"Josch, Sebastian, Steffen Jesinghausen, and Hans-Joachim Schmid. “Development of an Adaptive Coaxial Concrete Rheometer and Rheological Characterisation of Fresh Concrete.” Applied Rheology 33, no. 1 (2023). https://doi.org/10.1515/arh-2022-0140.","ama":"Josch S, Jesinghausen S, Schmid H-J.

This is mainly related to the constantly emerging challenges, such as not only the development of high-strength concretes is progressing very fast but also the simulation of the flow behaviour is of high importance. The main problem, however, is that the rheological characterisation of fresh concrete is not possible via commercial rheometers. The so-called concrete rheometers provide valuable relative values for comparing different concretes, but they cannot measure absolute values. Therefore, we developed an adaptive coaxial concrete rheometer (ACCR) that allows the measurement of fresh concrete with particles up to \r\n \r\n \r\n \r\n \r\n \r\n d\r\n \r\n \r\n max\r\n \r\n \r\n =\r\n 5.5\r\n \r\n mm\r\n \r\n {d}_{{\\rm{\\max }}}=5.5\\hspace{.5em}{\\rm{mm}}\r\n \r\n . The comparison of the ACCR with a commercial rheometer showed very good agreement for selected test materials (Newtonian fluid, shear thinning fluid, suspension, and yield stress fluid), so that self-compacting concrete was subsequently measured. Since these measurements showed a very high reproducibility, the rheological properties of the fresh concrete could be determined with high accuracy. The common flow models (Bingham (B), Herschel–Bulkley, modified Bingham (MB) models) were also tested for their applicability, with the Bingham and the modified Bingham model proving to be the best suitable ones."}],"user_id":"3959"},{"title":"Understanding the Redox Mechanism of Sulfurized Poly(acrylonitrile) as Highly Rate and Cycle Stable Cathode Material for Sodium-Sulfur Batteries","publication_status":"published","publication_identifier":{"issn":["0013-4651","1945-7111"]},"department":[{"_id":"35"},{"_id":"306"}],"doi":"10.1149/1945-7111/acb2fa","date_updated":"2023-05-03T08:27:13Z","language":[{"iso":"eng"}],"user_id":"89054","abstract":[{"lang":"eng","text":"Room temperature sodium-sulfur (RT Na-S) batteries are considered potential candidates for stationary power storage applications due to their low cost, broad active material availability and low toxicity.

Sulfurized poly(acrylonitrile) (SPAN) inherently inhibits the shuttling of PSs and shows compatibility with carbonate-based electrolytes, however, its exact redox mechanism remained unclear to date. Herein, we implement a commercially available and simple electrolyte into the Na-SPAN cell chemistry and demonstrate its high rate and cycle stability. Through the application of in situ techniques utilizing electronic impedance spectroscopy (EIS) and X-ray absorption spectroscopy (XAS) at different depths of charge and discharge, an insight into SPAN’s redox chemistry is obtained."}],"status":"public","date_created":"2023-01-30T16:08:15Z","volume":170,"author":[{"full_name":"Kappler, Julian","first_name":"Julian","last_name":"Kappler"},{"first_name":"Güldeniz","full_name":"Tonbul, Güldeniz","orcid":"0000-0002-0999-9995","last_name":"Tonbul","id":"89054"},{"last_name":"Schoch","id":"48467","first_name":"Roland","full_name":"Schoch, Roland","orcid":"0000-0003-2061-7289"},{"full_name":"Murugan, Saravanakumar","first_name":"Saravanakumar","last_name":"Murugan"},{"first_name":"Michał","orcid":"0000-0002-3734-7011","full_name":"Nowakowski, Michał","last_name":"Nowakowski","id":"78878"},{"last_name":"Lange","full_name":"Lange, Pia Lena","first_name":"Pia Lena"},{"last_name":"Klostermann","full_name":"Klostermann, Sina Vanessa","first_name":"Sina Vanessa"},{"orcid":"0000-0002-9294-6076","full_name":"Bauer, Matthias","first_name":"Matthias","id":"47241","last_name":"Bauer"},{"last_name":"Schleid","first_name":"Thomas","full_name":"Schleid, Thomas"},{"full_name":"Kästner, Johannes","first_name":"Johannes","last_name":"Kästner"},{"last_name":"Buchmeiser","full_name":"Buchmeiser, Michael Rudolf","first_name":"Michael Rudolf"}],"publisher":"The Electrochemical Society","keyword":["Materials Chemistry","Electrochemistry","Surfaces","Coatings and Films","Condensed Matter Physics","Renewable Energy","Sustainability and the Environment","Electronic","Optical and Magnetic Materials"],"publication":"Journal of The Electrochemical Society","issue":"1","article_number":"010526","_id":"40981","intvolume":" 170","year":"2023","citation":{"ieee":"J.

However, these devices are only able to compensate for a part of the dispersion (second-order dispersion). Here, we present a compact pulse-shaping device that uses plasmonic metasurfaces to apply an arbitrarily designed spectral phase delay allowing for a full dispersion control. Furthermore, with specific phase encodings, this device can be used to temporally reshape the incident laser pulses into more complex pulse forms such as a double pulse. We verify the performance of our device by using an SHG-FROG measurement setup together with a retrieval algorithm to extract the dispersion that our device applies to an incident laser pulse."}],"article_type":"original","language":[{"iso":"eng"}],"oa":"1","doi":"10.1021/acs.nanolett.2c04980","date_updated":"2023-05-12T11:17:51Z","project":[{"name":"TRR 142: TRR 142","_id":"53"},{"name":"TRR 142 - B: TRR 142 - Project Area B","_id":"55"},{"name":"TRR 142 - B09: TRR 142 - Subproject B09","_id":"170"},{"name":"TRR 142 - C07: TRR 142 - Subproject C07","_id":"171"},{"_id":"56","name":"TRR 142 - C: TRR 142 - Project Area C"}],"publication_status":"published","publication_identifier":{"issn":["1530-6984","1530-6992"]},"department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"title":"Compact Metasurface-Based Optical Pulse-Shaping Device"},{"quality_controlled":"1","publisher":"MDPI AG","author":[{"last_name":"Gnaase","id":"25730","first_name":"Stefan","full_name":"Gnaase, Stefan"},{"id":"77214","last_name":"Niggemeyer","full_name":"Niggemeyer, Dennis","first_name":"Dennis"},{"first_name":"Dennis","full_name":"Lehnert, Dennis","last_name":"Lehnert","id":"90491"},{"id":"93904","last_name":"Bödger","full_name":"Bödger, Christian","first_name":"Christian"},{"last_name":"Tröster","id":"553","first_name":"Thomas","full_name":"Tröster, Thomas"}],"publication":"Crystals","keyword":["Inorganic Chemistry","Condensed Matter Physics","General Materials Science","General Chemical Engineering"],"status":"public","date_created":"2023-01-18T05:44:59Z","volume":13,"article_type":"original","abstract":[{"text":"(1) This work answers the question of whether and to what extent there is a significant difference in mechanical properties when different additive manufacturing processes are applied to the material 1.2709.

(2) Known process parameters for low-porosity parts were used to fabricate tensile strength specimens. Half of the specimens were heat-treated, and all specimens were tested for mechanical properties in a quasi-static tensile test. In addition, the material hardness was determined. (3) It was found that, firstly, heat treatment resulted in a sharp increase in mechanical properties such as hardness, elastic modulus, yield strength and ultimate strength. In addition to the increase in these properties, the elongation at break also decreases significantly after heat treatment. The choice of process, on the other hand, does not give either process a clear advantage in terms of mechanical properties but shows that it is necessary to consider the essential mechanical properties for a desired application.","lang":"eng"}],"user_id":"90491","type":"journal_article","year":"2023","citation":{"ieee":"S.
