--- _id: '58163' abstract: - lang: eng text: Fibre-reinforced polymers are increasingly used due to their high specific strength, making them suitable for local sheet metal reinforcement. This allows improved overall mechanical properties with reduced wall thickness of the sheet metal part and, thus, lower weight of the components. One of the main focuses of research into such hybrid structures is on the adhesive properties and the respective failure behaviour of the interfaces. Generally, the failure behaviour under the influence of mechanical loads can be divided into adhesive, cohesive and mixed-mode failure. The correlation between observed failure behaviour and adhesion properties of the hybrid composite materials is analysed in detail in this work. The hybrid composite consists of an aluminium sheet of the alloy EN AW‑6082 T6 and thermoset carbon fibre-reinforced plastic (CFRP) prepreg. The aluminium sheet was laser pretreated before hybrid production to improve the adhesion properties. The specimens studied were produced by the prepreg pressing process, in which the components are cured and joined simultaneously. The influences of the thickness of the CFRP part, the layup, the fibre orientation at the boundary layer, and the laser pretreatment parameters on the properties of the hybrid joints were investigated. article_type: original author: - first_name: Shuang full_name: Wu, Shuang id: '48039' last_name: Wu orcid: 0000-0001-8645-9952 - first_name: Alexander full_name: Delp, Alexander last_name: Delp - first_name: Jonathan full_name: Freund, Jonathan last_name: Freund - first_name: Frank full_name: Walther, Frank last_name: Walther - first_name: Jan full_name: Haubrich, Jan last_name: Haubrich - first_name: Miriam full_name: Löbbecke, Miriam last_name: Löbbecke - first_name: Thomas full_name: Tröster, Thomas id: '553' last_name: Tröster citation: ama: Wu S, Delp A, Freund J, et al.

It focuses on approval processes and criteria set by the 16 federal states, arguing that these have the potential to influence the development of DCR. Using qualitative content analysis, the study explores three research questions: which DCR require official approval, the criteria applied for approval, and the extent to which these criteria are mathematics-specific. Findings indicate that 10 federal states maintain official approval systems, covering digital equivalents of printed textbooks and selected supplemental materials. However, most DCR fall outside these regulated processes, leaving their evaluation largely to individual schools and teachers. The study identifies 17 categories of quality criteria, but reveals a lack of detailed, mathematics-specific requirements. Instead, many criteria are broad references to didactical principles and educational goals, leaving the interpretation and application of these quality standards open-ended. Subject-specific criteria are included but remain limited in specificity. The study underscores the need for research-informed, mathematics-specific quality standards to guide DCR development and approval, emphasizing their importance amidst challenges like artificial intelligence. Policymakers are urged to adopt clearer criteria to ensure high-quality DCR to be used in schools.' article_type: original author: - first_name: Sebastian full_name: Rezat, Sebastian id: '31132' last_name: Rezat citation: ama: Rezat S.

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. author: - first_name: Lilia full_name: Schuster, Lilia last_name: Schuster - first_name: Viktoria full_name: Olfert, Viktoria id: '5974' last_name: Olfert - first_name: Oleksii full_name: Sherepenko, Oleksii last_name: Sherepenko - first_name: Clemens full_name: Fehrenbach, Clemens last_name: Fehrenbach - first_name: Shiyuan full_name: Song, Shiyuan last_name: Song - first_name: David full_name: Hein, David id: '7728' last_name: Hein - first_name: Gerson full_name: Meschut, Gerson id: '32056' last_name: Meschut orcid: 0000-0002-2763-1246 - first_name: Elliot full_name: Biro, Elliot last_name: Biro - first_name: Sebastian full_name: Münstermann, Sebastian last_name: Münstermann 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. article_number: '117' author: - first_name: Dennis full_name: Milaege, Dennis id: '35461' last_name: Milaege - first_name: Niklas full_name: Eschemann, Niklas last_name: Eschemann - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: Milaege D, Eschemann N, Hoyer K-P, Schaper M.

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. article_type: original author: - first_name: Xiaokun full_name: Ge, Xiaokun last_name: Ge - first_name: Marten full_name: Huck, Marten last_name: Huck - first_name: Andreas full_name: Kuhlmann, Andreas last_name: Kuhlmann - first_name: Michael full_name: Tiemann, Michael id: '23547' last_name: Tiemann orcid: 0000-0003-1711-2722 - first_name: Christian full_name: Weinberger, Christian id: '11848' last_name: Weinberger - first_name: Xiaodan full_name: Xu, Xiaodan last_name: Xu - first_name: Zhenyu full_name: Zhao, Zhenyu last_name: Zhao - first_name: Hans-Georg full_name: Steinrueck, Hans-Georg last_name: Steinrueck citation: ama: Ge X, Huck M, Kuhlmann A, et al.

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. article_type: original author: - first_name: Ulises full_name: Acevedo-Salas, Ulises last_name: Acevedo-Salas - first_name: Boris full_name: Croes, Boris last_name: Croes - first_name: Yide full_name: Zhang, Yide last_name: Zhang - first_name: Olivier full_name: Cregut, Olivier last_name: Cregut - first_name: Kokou Dodzi full_name: Dorkenoo, Kokou Dodzi last_name: Dorkenoo - first_name: Benjamin full_name: Kirbus, Benjamin last_name: Kirbus - first_name: Ekta full_name: Singh, Ekta last_name: Singh - first_name: Henrik full_name: Beccard, Henrik last_name: Beccard - first_name: Michael full_name: Rüsing, Michael id: '22501' last_name: Rüsing orcid: 0000-0003-4682-4577 - first_name: Lukas M. full_name: Eng, Lukas M. last_name: Eng - first_name: Riccardo full_name: Hertel, Riccardo last_name: Hertel - first_name: Eugene A. full_name: Eliseev, Eugene A. last_name: Eliseev - first_name: Anna N. full_name: Morozovska, Anna N. last_name: Morozovska - first_name: Salia full_name: Cherifi-Hertel, Salia last_name: Cherifi-Hertel citation: ama: Acevedo-Salas U, Croes B, Zhang Y, et al.

Moreover, strain plays a key role, e.g., in the physics of ferroelectrics and, in particular, of their domain walls. μ-Raman spectroscopy is a well-suited technique for the investigation of such strain effects as it allows to measure the lattice dynamics locally. However, quantifying and reconstructing strain fields from Raman maps requires knowledge on the strain dependence of phonon frequencies. In this paper, we have analyzed both theoretically and experimentally the phonon frequencies in the widely used ferroelectrics lithium niobate and lithium tantalate as a function of uniaxial strain via density functional theory and μ-Raman spectroscopy. Overall, we find a good agreement between our ab initio models and the experimental data performed with a stress cell. The majority of phonons show an increase in frequency under compressive strain, whereas the opposite is observed for tensile strains. Moreover, for E-type phonons, we observe the lifting of degeneracy already at moderate strain fields (i.e., at ±0.2%) along the x and y directions. This paper, hence, allows for the systematic analysis of three-dimensional strains in modern-type bulk and thin-film devices assembled from lithium niobate and tantalate. article_number: '024420' article_type: original author: - first_name: Ekta full_name: Singh, Ekta last_name: Singh - first_name: Mike N. full_name: Pionteck, Mike N. last_name: Pionteck - first_name: Sven full_name: Reitzig, Sven last_name: Reitzig - first_name: Michael full_name: Lange, Michael last_name: Lange - first_name: Michael full_name: Rüsing, Michael id: '22501' last_name: Rüsing orcid: 0000-0003-4682-4577 - first_name: Lukas M. full_name: Eng, Lukas M. last_name: Eng - first_name: Simone full_name: Sanna, Simone last_name: Sanna citation: ama: Singh E, Pionteck MN, Reitzig S, et al.

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. article_number: '1423' author: - first_name: Sergej full_name: Neufeld, Sergej last_name: Neufeld - first_name: Uwe full_name: Gerstmann, Uwe id: '171' last_name: Gerstmann orcid: 0000-0002-4476-223X - first_name: Laura full_name: Padberg, Laura id: '40300' last_name: Padberg - first_name: Christof full_name: Eigner, Christof id: '13244' last_name: Eigner orcid: https://orcid.org/0000-0002-5693-3083 - first_name: Gerhard full_name: Berth, Gerhard id: '53' last_name: Berth - first_name: Christine full_name: Silberhorn, Christine id: '26263' last_name: Silberhorn - first_name: Lukas M. full_name: Eng, Lukas M. last_name: Eng - first_name: Wolf Gero full_name: Schmidt, Wolf Gero id: '468' last_name: Schmidt orcid: 0000-0002-2717-5076 - first_name: Michael full_name: Rüsing, Michael id: '22501' last_name: Rüsing orcid: 0000-0003-4682-4577 citation: ama: Neufeld S, Gerstmann U, Padberg L, et al.

Elemental composition of Nb and Ta was investigated using XRF analysis, and small samples with homogeneous and well known composition were used for the DSC measurements.

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. article_number: '1592' author: - first_name: Sudipta full_name: Pramanik, Sudipta last_name: Pramanik - first_name: Dennis full_name: Milaege, Dennis last_name: Milaege - first_name: Maxwell full_name: Hein, Maxwell id: '52771' last_name: Hein orcid: 0000-0002-3732-2236 - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: 'Pramanik S, Milaege D, Hein M, Hoyer K-P, Schaper M.

In this work, a cutting-edge nano-lithography-based method to control the local orientation of a thermotropic liquid crystal is applied to easily available commercial standard materials and evaluated. Parallel nanogrooves on a substrate, created through 3D nanoprinting in a negative-tone photoresin optimized for two-photon polymerization are used for this purpose. Azimuthal anchoring energies of the order from 10−6 J/m2 to 10−5 J/m2 are found, depending on the spacing, width and depth of the grooves. In part, these values are larger than those reported previously for another photopolymer. Both uniform alignment and spatial patterns of different alignment directions can be realized. Electro-optic studies confirm the suitability of the method for electrically addressable photonic applications and indicate strong polar anchoring. article_number: '3467' author: - first_name: Bingru full_name: Zhang, Bingru last_name: Zhang - first_name: Malte full_name: Plidschun, Malte last_name: Plidschun - first_name: Markus A. full_name: Schmidt, Markus A. last_name: Schmidt - first_name: Heinz-Siegfried full_name: Kitzerow, Heinz-Siegfried id: '254' last_name: Kitzerow citation: ama: Zhang B, Plidschun M, Schmidt MA, Kitzerow H-S.
