title: Motion of water-immersed superparamagnetic microparticles on top of a topographically flat thin film substrate imprinted with engineered magnetic stripe domains of gradually increasing/decreasing stripe width and alternating head-to-head/tail-to-tail magnetization configuration

description: The controlled transport and fractionation of magnetic microparticles according to their structural and magnetic properties is of great importance for the realization of miniaturized Lab-on-a-chip devices, applicable, e.g., for medical point-of-care diagnostics. We designed a transport and pre-sorting system for superparamagnetic beads based on an engineered magnetic stray field landscape emerging from a magnetic stripe domain pattern inside an exchange-biased thin film system. The magnetic stripe domains were imprinted into the system via ion bombardment induced magnetic patterning. The pattern consists of stripe domains with gradually increasing and decreasing stripe width, periodically repeated across the whole substrate. Directed motion of superparamagnetic beads above the substrate inside a quiescent liquid (water) is induced by applying weak external magnetic field pulses, superposing the static magnetic stray field landscape. The beads are forced to perform a jumping motion with increasing/decreasing jump length owing to the arrangement of the underlying domain pattern. Our data shows a simultaneous fractionation of all particles into mobile and immobile units according to their magnetophoretic mobilities. The motion velocity of the particles is thereby a function of jump length (stripe domain width) and the magnitude of the external field pulses. Superparamagnetic beads of significantly different sizes can be spatially separated using a short sequence of constant field pulses. Videos of the particle motion were recorded using high-speed cameras attached to an optical microscope. The water-dispersed particles were placed on top of the magnetically patterned substrate inside a microfluidic chamber and motion was initiated by applying periodically repeated magnetic field pulses (pulse lengths in the ms-range; pulse magnitudes in the mT-range) using orthogonally arranged Helmholtz coils. The videos were analyzed qualitatively and quantitatively (particle velocity) using a custom Python code.

title: Agroecological pest control through mulch in potatoes - Delayed population development of Leptinotarsa decemlineata [Dataset]
title: Transfer mulch inhibits L. decemlineata

description: Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae) is one of the most relevant pests in potato cultivation and even in organic potatoes, it is often managed using pesticides. Mulching potatoes represents an alternative to reduce egg masses and larvae of L. decemlineata. In three 4-fold replicated field trials with unmulched control plots (a) in comparison to plots mulched with grass-clover (b) or triticale-vetch (c) the effects on L. decemlineata population dynamics were assessed. In 2020 and 2021, larvae and their respective developmental stage of L. decemlineata were recorded twice weekly on 30 marked potato plants per plot. In 2022 assessments took place 3 times during the season on 16 plants per plot. To examine the influence of changed microclimatic conditions due to mulching, temperature loggers were installed 15 cm above the canopy and belowground. The number of larvae of L. decemlineata was significantly reduced on average by 65 % in the mulched treatments and higher larval stages occurred later and in lower numbers compared to the unmulched plots. In 2022, also a significant reduction of second-generation adults of L. decemlineata could be observed. During warm and hot weather, the canopy temperatures in the mulched plots considerably exceeded those of the unmulched plots, often reaching peak temperatures well above the optimum for L. decemlineata development. Mulching leads either to delayed or reduced immigration of adult beetles as well as potentially to slower egg and larval development.

title: Pathways toward the Use of Non-Destructive Micromagnetic Analysis for Porosity Assessment and Process Parameter Optimization in Additive Manufacturing of 42CrMo4 (AISI 4140) [Dataset]

description: Laser-based powder bed fusion of metals (PBF-LB/M) is a widely applied additive manufacturing technique. Thus, PBF-LB/M represents a potential candidate for the processing of quenched and tempered (Q&T) steels such as 42CrMo4 (AISI 4140), as these steels are often considered as the material of choice for complex components, e.g., in the toolmaking industry. However, due to the presence of process-induced defects, achieving a high quality of the resulting parts remains challenging in PBF-LB/M. Therefore, an extensive quality inspection, e.g., using process monitoring systems or downstream by destructive or non-destructive testing (NDT) methods, is essential. Since conventionally used downstream methods, e.g., X-ray computed tomography, are time-consuming and cost-intensive, micromagnetic NDT measurements represent an alternative for ferromagnetic materials such as 42CrMo4. A system combining several micromagnetic NDT measurement methods is the micromagnetic multiparametric microstructure and stress analyzer (3MA), developed by the Fraunhofer Institute for Nondestructive Testing IZFP (Saarbrücken, Germany). The results of 3MA measurements have already been correlated with various material properties, however, the use of the 3MA technology for the quality inspection of AM components was missing. To investigate the potential of the 3MA technology in this context, potential relations between micromagnetic properties and the porosity of AM components was investigated in the study described in https://doi.org/10.3390/ma17050971. In the study, 42CrMo4 samples were manufactured by PBF-LB/M with different process parameters. The samples were analyzed using a 3MA system and porosity values determined by image analysis of micrographs. Using multiple regression modeling, relations between the PBF-LB/M process parameters and six selected micromagnetic variables and relations between the process parameters and the porosity were assessed. The results reveal first insights into the use of micromagnetic NDT measurements for porosity assessment and process parameter optimization in PBF-LB/M-processed components.
description: This dataset provides the PBF-LB/M process parameter combinations, the results of the micromagnetic NDT measurements, and the porosity values which were used to develop the predictive models using a data-driven approach. Moreover, meta data about the experimental design, the sample manufacturing, the micromagnetic NDT measurements, the image capturing, and the porosity determination are given.

title: Mechanical Properties of Ultra-High Performance Concrete (UHPC)

description: Ultra-high-performance concrete (UHPC) possesses mechanical characteristics that significantly outperform traditional concrete. However, replicating these properties consistently across different production batches—even when using the same recipe—remains a challenge. This dataset examines how variations in raw materials, environmental conditions, dosage variation, and both mixing and curing practices affect the mechanical properties of UHPC produced from a single reference formulation. Designed according to a three-phase design of experiments methodology, the dataset comprises 150 systematically planned experiments, offering a comprehensive view of the multiple factors influencing UHPC quality. Measurements of compressive and flexural strengths are provided at 24 hours and after 28 days post-mixing. Beside the mechanical properties, the dataset includes five characteristics of the fresh state, measured directly after each mixing process. All experiments are conducted in the laboratory of G.tec Engineering GmbH under controlled conditions, using the same mixer, same mixing tool, and the same team of technicians. The environment is maintained at a constant temperature of 20 °C throughout the experimental process. From each experiment, three specimens are cured under the designed conditions. First, the flexural strength is measured by carefully halving each of the three specimens. Then, the resulting six halves are used to measure the compressive strength. Finally, after a careful analysis of the results from each specimen, the averages for flexural and compressive strengths are reported. The dataset also includes outliers. After analysis by UHPC experts and the data science team, 11 data points (numbered 5, 17, 30, 36, 41, 47, 57, 99, 101, 128, and 148) were identified and removed as outliers to assure data quality. By offering a structured collection of high-dimensional data and a relatively small data size, this dataset is particularly suitable for advanced regression analyses, notably those addressing sparse data scenarios.

title: Impact of a single-side 100Cr6 clad layer on the tensile and fatigue properties of S550MC steel [Dataset]

description: The production of newly developed hot-rolled layered metal composites (LMC) leads to the availability of sheet materials with specifically adjustable, graded properties being cost-effective and suitable for large-scale production. As many of the envisaged applications of these LMC, e.g., clutch disc carriers, suffer from cyclic loading during service life, a fundamental knowledge of the fatigue behavior is required in order to ensure safe and reliable application of the components. Therefore, the study described in https://doi.org/10.1111/ffe.14383 focuses on the fatigue behavior of a hot-rolled two-layer LMC consisting of a S550MC substrate layer and a 100Cr6 clad layer. In order to investigate the influence of the clad layer, two conditions are directly compared, i.e., the two-layer laminate cladded steel and the single-layer substrate condition.
description: This dataset focuses on the fatigue and tensile behavior as well as the corresponding fracture surfaces, microstructure and hardness distribution of the two-layer cladded steel and the substrate.

title: Correlation of the crystalline structure, moisture content, texture and aging-induced degradation of polyamide 5.10 using wide-angle x-ray scattering analysis [Dataset]

description: This study provides a detailed analysis of the crystalline structure of polyamide 5.10 (PA5.10) and determines the effects of hydrothermal aging on its moisture content, crystallinity, and texture. Using wide-angle X-ray scattering (WAXS), the investigation revealed insights into both the amorphous boundary layer and the semi-crystalline core, with a Python script based on Bragg’s law enabling precise identification of crystalline phase planes. Gaussian fitting of crystalline peaks further refined the structural understanding. The effects of experimental parameters on WAXS measurements were examined to identify additional factors influencing PA5.10. Hydrothermal aging led to notable changes, including increased moisture absorption, volume expansion, enhanced crystallinity, and shifts in molecular structure and crystalline morphology. WAXS showed that moisture-induced scattering reduced intensity, which was reversible upon re-drying. Despite an increase in crystallinity observed by DSC, WAXS did not capture a corresponding shift, likely due to the combined effects of residual moisture and annealing processes. Overall, this study enhances the understanding of PA5.10's crystalline behavior under hydrothermal exposure and provides a basis for future investigations into its aging processes and structural evolution. These findings contribute to a broader understanding of the long-term degradation mechanisms and stability of bio-based polyamides under hydrothermal and humid conditions. Moreover, the insights gained are relevant for predicting material performance in moisture-sensitive applications and can inform the development of stabilization strategies for hygroscopic polymers.<br><br>This dataset consists of the measured data from the conducted experiments, python scripts as well as the data analysis.<br>In case you use the data please cite the corresponding article.

title: Data selection strategies for minimizing measurement time in materials characterization, measurement data

description: Every new material needs to be assessed and qualified for an envisaged application. A steadily increasing number of new alloys, designed to address challenges in terms of reliability and sustainability, poses significant demands on well-known analysis methods in terms of their efficiency, e.g., in X-Ray diffraction analysis. Particularly in laboratory measurements, where the intensities in diffraction experiments tend to be low, a possibility to adapt the exposure time to the prevailing boundary conditions, i.e., the investigated microstructure, is seen to be a very effective approach. The counting time is decisive for, e.g., complex texture, phase, and residual stress measurements. Traditionally, more measurement points and, thus, longer data collection times lead to more accurate information. Here, too short counting times result in poor signal-to-background ratios and dominant signal noise, respectively, rendering subsequent evaluation more difficult or even impossible. Then, it is necessary to repeat experiments with adjusted, usually significantly longer counting time. To prevent redundant measurements, it is state-of-the-art to always consider the entire measurement range, regardless of whether the investigated points are relevant and contribute to the subsequent materials characterization, respectively. Obviously, this kind of approach is extremely time consuming and, eventually, not efficient. All relevant data including the code are carefully assessed and will be the basis for a widely adapted strategy enabling efficient measurements not only in lab environments but also large scale facilities. <br><br>This data set consists of the fully measured data from the diffraction experiments as well as the manuscript for data analyzing.<br><br>IMPORTANT: In case you use the data please cite our corresponding article: https://doi.org/10.1038/s41598-025-96221-1
