The effect of weld nugget shape and material property gradients is studied based on damage mechanics modeling and experimental validation to shed light on the underlying influencing factors. 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.</jats:p>","lang":"eng"}],"status":"public","_id":"50726","user_id":"5974","department":[{"_id":"157"}],"keyword":["Materials Chemistry","Metals and Alloys","Physical and Theoretical Chemistry","Condensed Matter Physics"],"language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"issn":["1611-3683","1869-344X"]},"quality_controlled":"1","year":"2024","citation":{"ama":"Schuster L, Olfert V, Sherepenko O, et al.

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.</jats:p>","lang":"eng"}],"keyword":["Inorganic Chemistry","Condensed Matter Physics","General Materials Science","General Chemical Engineering"],"language":[{"iso":"eng"}],"quality_controlled":"1","issue":"2","year":"2024","publisher":"MDPI AG","date_created":"2024-03-22T13:46:37Z","title":"Anisotropic Mechanical and Microstructural Properties of a Ti-6Al-7Nb Alloy for Biomedical Applications Manufactured via Laser Powder Bed Fusion","type":"journal_article","status":"public","_id":"52738","user_id":"35461","department":[{"_id":"158"},{"_id":"321"}],"article_number":"117","publication_status":"published","publication_identifier":{"issn":["2073-4352"]},"citation":{"ieee":"D.

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."}],"publication":"Journal of The Electrochemical Society","title":"Electrochemical Removal of HF from Carbonate-based LiPF6-containing Li-ion Battery Electrolytes","publisher":"The Electrochemical Society","date_created":"2024-03-08T06:27:10Z","year":"2024","quality_controlled":"1","article_type":"original","_id":"52372","user_id":"23547","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"status":"public","type":"journal_article","main_file_link":[{"url":"https://dx.doi.org/10.1149/1945-7111/ad30d3","open_access":"1"}],"doi":"10.1149/1945-7111/ad30d3","oa":"1","date_updated":"2024-03-25T17:01:09Z","author":[{"last_name":"Ge","full_name":"Ge, Xiaokun","first_name":"Xiaokun"},{"last_name":"Huck","full_name":"Huck, Marten","first_name":"Marten"},{"first_name":"Andreas","full_name":"Kuhlmann, Andreas","last_name":"Kuhlmann"},{"first_name":"Michael","id":"23547","full_name":"Tiemann, Michael","last_name":"Tiemann","orcid":"0000-0003-1711-2722"},{"last_name":"Weinberger","full_name":"Weinberger, Christian","id":"11848","first_name":"Christian"},{"first_name":"Xiaodan","full_name":"Xu, Xiaodan","last_name":"Xu"},{"first_name":"Zhenyu","last_name":"Zhao","full_name":"Zhao, Zhenyu"},{"first_name":"Hans-Georg","last_name":"Steinrueck","full_name":"Steinrueck, Hans-Georg"}],"volume":171,"citation":{"ieee":"X.

Despite their reduced dimensionality, they can exhibit complex non-Ising polarization configurations and unexpected physical properties. Here, the impact of the three-dimensional (3D) curvature on the polarization profile of nominally uncharged 180° domain walls in LiNbO3 is studied using second-harmonic generation microscopy and 3D polarimetry analysis. Correlations between the domain-wall curvature and the variation of its internal polarization unfold in the form of modulations of the Néel-like character, which we attribute to the flexoelectric effect. While the Néel-like character originates mainly from the tilting of the domain wall, the internal polarization adjusts its orientation due to the synergetic upshot of dipolar and monopolar bound charges and their variation with the 3D curvature. Our results show that curved interfaces in solid crystals may offer a rich playground for tailoring nanoscale polar states.","lang":"eng"}],"date_updated":"2023-10-11T09:06:31Z","author":[{"first_name":"Ulises","full_name":"Acevedo-Salas, Ulises","last_name":"Acevedo-Salas"},{"first_name":"Boris","last_name":"Croes","full_name":"Croes, Boris"},{"first_name":"Yide","full_name":"Zhang, Yide","last_name":"Zhang"},{"last_name":"Cregut","full_name":"Cregut, Olivier","first_name":"Olivier"},{"first_name":"Kokou Dodzi","last_name":"Dorkenoo","full_name":"Dorkenoo, Kokou Dodzi"},{"last_name":"Kirbus","full_name":"Kirbus, Benjamin","first_name":"Benjamin"},{"last_name":"Singh","full_name":"Singh, Ekta","first_name":"Ekta"},{"full_name":"Beccard, Henrik","last_name":"Beccard","first_name":"Henrik"},{"first_name":"Michael","orcid":"0000-0003-4682-4577","last_name":"Rüsing","id":"22501","full_name":"Rüsing, Michael"},{"first_name":"Lukas M.","full_name":"Eng, Lukas M.","last_name":"Eng"},{"last_name":"Hertel","full_name":"Hertel, Riccardo","first_name":"Riccardo"},{"last_name":"Eliseev","full_name":"Eliseev, Eugene A.","first_name":"Eugene A."},{"first_name":"Anna N.","full_name":"Morozovska, Anna N.","last_name":"Morozovska"},{"first_name":"Salia","last_name":"Cherifi-Hertel","full_name":"Cherifi-Hertel, Salia"}],"volume":23,"doi":"10.1021/acs.nanolett.2c03579","publication_status":"published","publication_identifier":{"issn":["1530-6984","1530-6992"]},"citation":{"mla":"Acevedo-Salas, Ulises, et al. “Impact of 3D Curvature on the Polarization Orientation in Non-Ising Domain Walls.” <i>Nano Letters</i>, vol. 23, no. 3, American Chemical Society (ACS), 2023, pp. 795–803, doi:<a href=\"https://doi.org/10.1021/acs.nanolett.2c03579\">10.1021/acs.nanolett.2c03579</a>.","bibtex":"@article{Acevedo-Salas_Croes_Zhang_Cregut_Dorkenoo_Kirbus_Singh_Beccard_Rüsing_Eng_et al._2023, title={Impact of 3D Curvature on the Polarization Orientation in Non-Ising Domain Walls}, volume={23}, DOI={<a href=\"https://doi.org/10.1021/acs.nanolett.2c03579\">10.1021/acs.nanolett.2c03579</a>}, number={3}, journal={Nano Letters}, publisher={American Chemical Society (ACS)}, author={Acevedo-Salas, Ulises and Croes, Boris and Zhang, Yide and Cregut, Olivier and Dorkenoo, Kokou Dodzi and Kirbus, Benjamin and Singh, Ekta and Beccard, Henrik and Rüsing, Michael and Eng, Lukas M. and et al.}, year={2023}, pages={795–803} }","short":"U.

The fabrication of low-loss optical waveguides, as well as high-grade periodically poled ferroelectric domain structures, requires a profound understanding of the material properties and crystal structure. In this regard, Raman spectroscopy offers the possibility to study and visualize domain structures, strain, defects, and the local stoichiometry, which are all factors impacting device performance. However, the accurate interpretation of Raman spectra and their changes with respect to extrinsic and intrinsic defects requires a thorough assignment of the Raman modes to their respective crystal features, which to date is only partly conducted based on phenomenological modelling. To address this issue, we calculated the phonon spectra of potassium titanyl phosphate and the related compounds rubidium titanyl phosphate (RbTiOPO4) and potassium titanyl arsenate (KTiOAsO4) based on density functional theory and compared them with experimental data. Overall, this allows us to assign various spectral features to eigenmodes of lattice substructures with improved detail compared to previous assignments. Nevertheless, the analysis also shows that not all features of the spectra can unambigiously be explained yet. A possible explanation might be that defects or long range fields not included in the modeling play a crucial rule for the resulting Raman spectrum. In conclusion, this work provides an improved foundation into the vibrational properties in the KTiOPO4 material family."}],"publication":"Crystals","title":"Vibrational Properties of the Potassium Titanyl Phosphate Crystal Family","date_created":"2023-10-11T09:10:53Z","publisher":"MDPI AG","year":"2023","issue":"10","quality_controlled":"1"},{"year":"2023","quality_controlled":"1","issue":"1","title":"Solid solutions of lithium niobate and lithium tantalate: crystal growth and the ferroelectric transition","publisher":"Informa UK Limited","date_created":"2023-10-11T09:10:08Z","abstract":[{"lang":"eng","text":"Specific heat capacity measurements by differential scanning calorimetry (DSC) of single crystals of solid solutions of LiNbO3 and LiTaO3 are reported and compared with corresponding ab initio calculations, with the aim to investigate the variation of the ferroelectric Curie temperature as a function of composition.

To mitigate the narrowing of coronary artery atherosclerosis (stenosis), the computational modelling of auxetic and non-auxetic stents was performed in this study to minimise or even avoid these deposition agents in the future. Computational modelling was performed in unrestricted (open) conditions and restricted (in an artery) conditions. Finally, stent designs were produced by additive manufacturing, and mechanical testing of the stents was undertaken. Auxetic stent 1 and auxetic stent 2 exhibit very little foreshortening and radial recoil in unrestricted deployment conditions compared to non-auxetic stent 3. However, stent 2 shows structural instability (strut failure) during unrestricted deployment conditions. For the restricted deployment condition, stent 1 shows a higher radial recoil compared to stent 3. In the tensile test simulations, short elongation for stent 1 due to strut failure is demonstrated, whereas no structural instability is noticed for stent 2 and stent 3 until 0.5 (mm/mm) strain. The as-built samples show a significant thickening of the struts of the stents resulting in short elongations during tensile testing compared to the simulations (stent 2 and stent 3). A modelling framework for the stent deployment system that enables the selection of appropriate stent designs before in vivo testing is required. This leads to the acceleration of the development process and a reduction in time, resulting in less material wastage. The modelling framework shall be useful for doctors designing patient-specific stents.</jats:p>"}],"publication":"Crystals","doi":"10.3390/cryst13111592","volume":13,"author":[{"full_name":"Pramanik, Sudipta","last_name":"Pramanik","first_name":"Sudipta"},{"full_name":"Milaege, Dennis","last_name":"Milaege","first_name":"Dennis"},{"first_name":"Maxwell","orcid":"0000-0002-3732-2236","last_name":"Hein","full_name":"Hein, Maxwell","id":"52771"},{"full_name":"Hoyer, Kay-Peter","id":"48411","last_name":"Hoyer","first_name":"Kay-Peter"},{"first_name":"Mirko","last_name":"Schaper","id":"43720","full_name":"Schaper, Mirko"}],"date_updated":"2023-11-21T15:30:57Z","intvolume":"        13","citation":{"chicago":"Pramanik, Sudipta, Dennis Milaege, Maxwell Hein, Kay-Peter Hoyer, and Mirko Schaper. “Additive Manufacturing and Mechanical Properties of Auxetic and Non-Auxetic Ti24Nb4Zr8Sn Biomedical Stents: A Combined Experimental and Computational Modelling Approach.” <i>Crystals</i> 13, no. 11 (2023). <a href=\"https://doi.org/10.3390/cryst13111592\">https://doi.org/10.3390/cryst13111592</a>.","ieee":"S.

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."}],"status":"public","_id":"43391","user_id":"7828","department":[{"_id":"728"},{"_id":"145"},{"_id":"393"},{"_id":"9"}],"keyword":["Physical and Theoretical Chemistry","Condensed Matter Physics"],"language":[{"iso":"eng"}]},{"publisher":"Walter de Gruyter GmbH","date_created":"2023-03-16T19:06:49Z","title":"Development of an adaptive coaxial concrete rheometer and rheological characterisation of fresh concrete","quality_controlled":"1","issue":"1","year":"2023","keyword":["Condensed Matter Physics","General Materials Science"],"language":[{"iso":"eng"}],"publication":"Applied Rheology","abstract":[{"lang":"eng","text":"<jats:title>Abstract</jats:title>\r\n               <jats:p>The accessibility to rheological parameters for concrete is becoming more and more relevant. 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 <jats:inline-formula>\r\n                     <jats:alternatives>\r\n                        <jats:inline-graphic xmlns:xlink=\"http://www.w3.org/1999/xlink\" xlink:href=\"graphic/j_arh-2022-0140_eq_001.png\" />\r\n                        <m:math xmlns:m=\"http://www.w3.org/1998/Math/MathML\">\r\n                           <m:msub>\r\n                              <m:mrow>\r\n                                 <m:mi>d</m:mi>\r\n                              </m:mrow>\r\n                              <m:mrow>\r\n                                 <m:mi mathvariant=\"normal\">max</m:mi>\r\n                              </m:mrow>\r\n                           </m:msub>\r\n                           <m:mo>=</m:mo>\r\n                           <m:mn>5.5</m:mn>\r\n                           <m:mspace width=\".5em\" />\r\n                           <m:mi mathvariant=\"normal\">mm</m:mi>\r\n                        </m:math>\r\n                        <jats:tex-math>{d}_{{\\rm{\\max }}}=5.5\\hspace{.5em}{\\rm{mm}}</jats:tex-math>\r\n                     </jats:alternatives>\r\n                  </jats:inline-formula>. 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.</jats:p>"}],"oa":"1","date_updated":"2023-04-27T11:19:08Z","author":[{"first_name":"Sebastian","id":"38243","full_name":"Josch, Sebastian","last_name":"Josch"},{"first_name":"Steffen","last_name":"Jesinghausen","orcid":"https://orcid.org/0000-0003-2611-5298","id":"3959","full_name":"Jesinghausen, Steffen"},{"last_name":"Schmid","orcid":"000-0001-8590-1921","full_name":"Schmid, Hans-Joachim","id":"464","first_name":"Hans-Joachim"}],"volume":33,"main_file_link":[{"open_access":"1","url":"https://www.degruyter.com/document/doi/10.1515/arh-2022-0140/html"}],"doi":"10.1515/arh-2022-0140","publication_status":"published","publication_identifier":{"issn":["1617-8106"]},"citation":{"ama":"Josch S, Jesinghausen S, Schmid H-J.

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.","lang":"eng"}],"status":"public","_id":"40981","department":[{"_id":"35"},{"_id":"306"}],"user_id":"89054","keyword":["Materials Chemistry","Electrochemistry","Surfaces","Coatings and Films","Condensed Matter Physics","Renewable Energy","Sustainability and the Environment","Electronic","Optical and Magnetic Materials"],"article_number":"010526","language":[{"iso":"eng"}]},{"year":"2023","issue":"8","quality_controlled":"1","title":"Compact Metasurface-Based Optical Pulse-Shaping Device","date_created":"2023-04-18T05:47:22Z","publisher":"American Chemical Society (ACS)","file":[{"content_type":"application/pdf","relation":"main_file","success":1,"creator":"zentgraf","date_created":"2023-04-18T05:50:19Z","date_updated":"2023-04-18T05:50:19Z","access_level":"closed","file_name":"acs.nanolett.2c04980.pdf","file_id":"44045","file_size":1315966}],"abstract":[{"lang":"eng","text":"Dispersion is present in every optical setup and is often an undesired effect, especially in nonlinear-optical experiments where ultrashort laser pulses are needed. Typically, bulky pulse compressors consisting of gratings or prisms are used\r\nto address this issue by precompensating the dispersion of the optical components. 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."}],"publication":"Nano Letters","language":[{"iso":"eng"}],"keyword":["Mechanical Engineering","Condensed Matter Physics","General Materials Science","General Chemistry","Bioengineering"],"ddc":["530"],"intvolume":"        23","page":"3196 - 3201","citation":{"ama":"Geromel R, Georgi P, Protte M, et al.

So, the surface dissolution of additively manufactured FeCo samples is investigated in a quasi-<jats:italic>in situ</jats:italic> manner, in particular, the pitting corrosion in 5.0 wt pct NaCl solution. The local dissolution of the same sample region is monitored after 24, 72, and 168 hours. Here, the formation of rectangular and circular pits of ultra-fine dimensions (less than 0.5 <jats:italic>µ</jats:italic>m) is observed with increasing immersion time. In addition, the formation of a corrosion-inhibiting surface layer is detected on the sample surface. Surface dissolution leads to a change in the surface structure, however, no change in grain shape or grain size is noticed. The surface topography after local dissolution is correlated to the grain orientation. Quasi-<jats:italic>in situ</jats:italic> analysis shows the preferential dissolution of high-angle grain boundaries (HAGBs) leading to a change in the fraction of HAGBs and low-angle grain boundaries fraction (LAGBs). For the FeCo sample, a potentiodynamic polarisation test reveals a corrosion potential (E<jats:sub>corr</jats:sub>) of − 0.475 V referred to the standard hydrogen electrode (SHE) and a corrosion exchange current density (i<jats:sub>corr</jats:sub>) of 0.0848 A/m<jats:sup>2</jats:sup>. Furthermore, quasi-<jats:italic>in situ</jats:italic> experiments showed that grains oriented along certain crystallographic directions are corroding more compared to other grains leading to a significant decrease in the local surface height.

The Laser-Powder-Bed-Fusion (L-PBF) and Laser-Metal-Deposition (LMD) processes are considered, as they differ fundamentally in the way a part is manufactured. (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.</jats:p>"}],"publication":"Crystals"}]
