The field of carbon nanofibers has been growing in terms of technological development and seeking attention because of their dominant chemical properties, mechanical strength, and electrical conductivity. Catalytic and electrospinning techniques are currently the conventional methods for fabrication of carbon nanofibers in a two-step process that includes stabilization and carbonization of polyacrylonitrile (PAN) nanofibers, respectively. Recently, the industrial and medical sectors dealing with nanofibrous materials are not having ample options but to accept the use of already approved materials which are quite expensive and lack the flexibility in manipulating their surface and chemical properties for specific applications. To overcome these limitations, carbon nanofibers are being validated for their multifunctional role in various forms. This article reviews the recent advancements in the fabrication of carbon nanofibers and additionally pointing out their significance for applications in the industrial and biomedical sector for their potential role in the future. In this article, we explicitly focus on the recent breakthroughs in the field of carbon nanofibers, especially in the area of their commercial applications. Our goal is to depict ways for enhancing the chemical and structural properties of these nanofibers and providing beneficiary, low-cost alternatives to the currently available materials in the medical field as well as the industrial area.

Recent policy changes highlight the need for citizens to take adaptive actions to reduce flood-related impacts. Here, we argue that these changes represent a wider behavioral turn in flood risk management (FRM). The behavioral turn is based on three fundamental assumptions: first, that the motivations of citizens to take adaptive actions can be well understood so that these motivations can be targeted in the practice of FRM; second, that private adaptive measures and actions are effective in reducing flood risk; and third, that individuals have the capacities to implement such measures. We assess the extent to which the assumptions can be supported by empirical evidence. We do this by engaging with three intellectual catchments. We turn to research by psychologists and other behavioral scientists which focus on the sociopsychological factors which influence individual motivations (Assumption 1). We engage with economists, engineers, and quantitative risk analysts who explore the extent to which individuals can reduce flood related impacts by quantifying the effectiveness and efficiency of household-level adaptive measures (Assumption 2). We converse with human geographers and sociologists who explore the types of capacities households require to adapt to and cope with threatening events (Assumption 3). We believe that an investigation of the behavioral turn is important because if the outlined assumptions do not hold, there is a risk of creating and strengthening inequalities in FRM. Therefore, we outline the current intellectual and empirical knowledge as well as future research needs. Generally, we argue that more collaboration across intellectual catchments is needed, that future research should be more theoretically grounded and become methodologically more rigorous and at the same time focus more explicitly on the normative underpinnings of the behavioral turn.

The purpose of this study is to investigate the brand hate phenomenon for service products in a cross-channel setting (offline/online environment). To reach this objective, structural equation modeling was employed on a sample of 265 consumers. Findings reveal that brand hate positively influences offline negative word-of-mouth (NWOM), online complaining, and non-repurchase intention. Furthermore, while offline NWOM has a positive effect on non-repurchase intention, online complaining has a negative one. Finally, a mediated path was identified, which starts from brand hate and ends with non-repurchase intention through online complaining and offline NWOM. The study provides implications for firms’ marketers and practitioners.

Electrospinning can be used to prepare nanofiber mats from diverse polymers, polymer blends, or polymers doped with other materials. Amongst this broad range of usable materials, biopolymers play an important role in biotechnological, biomedical, and other applications. However, several of them are water-soluble, necessitating a crosslinking step after electrospinning. While crosslinking with glutaraldehyde or other toxic chemicals is regularly reported in the literature, here, we concentrate on methods applying non-toxic or low-toxic chemicals, and enzymatic as well as physical methods. Making gelatin nanofibers non-water soluble by electrospinning them from a blend with non-water soluble polymers is another method described here. These possibilities are described together with the resulting physical properties, such as swelling behavior, mechanical strength, nanofiber morphology, or cell growth and proliferation on the crosslinked nanofiber mats. For most of these non-toxic crosslinking methods, the degree of crosslinking was found to be lower than for crosslinking with glutaraldehyde and other common toxic chemicals.

Air pollution is one of the biggest health and environmental problems in the world and a huge threat to human health on a global scale. Due to the great impact of respiratory viral infections, chronic obstructive pulmonary disease, lung cancer, asthma, bronchitis, emphysema, lung disease, and heart disease, respiratory allergies are increasing significantly every year. Because of the special properties of electrospun nanofiber mats, e.g., large surface-to-volume ratio and low basis weight, uniform size, and nanoporous structure, nanofiber mats are the preferred choice for use in large-scale air filtration applications. In this review, we summarize the significant studies on electrospun nanofiber mats for filtration applications, present the electrospinning technology, show the structure and mechanism of air filtration. In addition, an overview of current air filtration materials derived from bio- and synthetic polymers and blends is provided. Apart from this, the use of biopolymers in filtration applications is still relatively new and this field is still under-researched. The application areas of air filtration materials are discussed here and future prospects are summarized in conclusion. In order to develop new effective filtration materials, it is necessary to understand the interaction between technology, materials, and filtration mechanisms, and this study was intended to contribute to this effort.

Optimization algorithms are widely employed for finding optimal solutions in many applications. Stochastic optimization algorithms including nature-inspired optimization algorithms are simple and easy to implement, and this is the reason why there is a growing interest in this research area. Recently, many nature-inspired optimization algorithms have been proposed for solving many optimization problems. Moreover, with the aim of improving the performance of optimization algorithms, some modifications were applied such as combining different algorithms and employing some sampling techniques for replacing critical parameters in the optimization algorithms. This paper compares five different widely used PSO-style optimization algorithms to investigate if there is a significant difference between them or not. Theoretically, we explain different PSO-style algorithms and discuss the similarities and differences between them. Practically, a number of experiments were conducted to compare these algorithms. Theoretical analysis and practical results prove that there is not any significant difference between the PSO-style algorithms regarding their performance. • Nature-inspired optimization algorithms are used to solve optimization problems. • Many comparisons are presented to compare PSO-style optimization algorithms. • Under the same metaheuristic framework, the algorithms perform similarly.

The exchange bias (EB) is an effect occurring in coupled ferromagnetic/antiferromagnetic materials of diverse shapes, from core–shell nanoparticles to stacked nanostructures and thin films. The interface coupling typically results in a horizontal—often also vertical—shift of the hysteresis loop, combined with an increased coercivity, as compared to the pure ferromagnet, and the possibility of asymmetric hysteresis loops. Several models have been developed since its discovery in 1956 which still have some drawbacks and some unexplained points, while exchange bias systems are at the same time being used in hard drive read heads and are part of highly important elements for spintronics applications. Here, we give an update of new theoretical models and experimental findings regarding exchange bias phenomena in thin films during the last years, including new material combinations in which an exchange bias was found.

Microelectromechanical systems (MEMS) are of high interest for recent electronic applications. Their applications range from medicine to measurement technology, from microfluidics to the Internet of Things (IoT). In many cases, MEMS elements serve as sensors or actuators, e.g., in recent mobile phones, but also in future autonomously driving cars. Most MEMS elements are based on silicon, which is not deformed plastically under a load, as opposed to metals. While highly sophisticated solutions were already found for diverse MEMS sensors, actuators, and other elements, MEMS fabrication is less standardized than pure microelectronics, which sometimes blocks new ideas. One of the possibilities to overcome this problem may be the 3D printing approach. While most 3D printing technologies do not offer sufficient resolution for MEMS production, and many of the common 3D printing materials cannot be used for this application, there are still niches in which the 3D printing of MEMS enables producing new structures and thus creating elements for new applications, or the faster and less expensive production of common systems. Here, we give an overview of the most recent developments and applications in 3D printing of MEMS.

Fused deposition modeling (FDM) is one of the most often-used technologies in additive manufacturing. Several materials are used with this technology, such as poly(lactic acid) (PLA), which is most commonly applied. The mechanical properties of 3D-printed parts depend on the process parameters. This is why, in this study, three-point bending tests were carried out to characterize the influence of build orientation, layer thickness, printing temperature and printing speed on the mechanical properties of PLA samples. Not only the process parameters may affect the mechanical properties, but heat after-treatment also has an influence on them. For this reason, additional samples were printed with optimal process parameters and characterized after pure heat treatment as well as after deformation at a temperature above the glass transition temperature, cooling with applied deformation, and subsequent recovery under heat treatment. These findings are planned to be used in a future study on finger orthoses that could either be printed according to shape or in a flat shape and afterwards heated and bent around the finger.

AbstractPrecise control of pore size and surface properties is crucial for effective and efficient membrane separation, yet it remains challenging with conventional polymer‐based membranes. In this study, this gap is addressed by integrating atomic layer deposition (ALD) of Al2O3 with nanometer‐thin carbon nanomembranes (CNMs) to achieve ultra‐selective separation properties. Structural characterizations confirm uniform Al2O3 deposition and the preservation of the CNM structure. The ALD process allows for precise modulation of the nanopore structure. Despite the pore shrinkage upon ALD, the increased hydrophilicity offered by Al2O3 enhances water permeance, achieving an exceptionally high water vapor permeation rate of 1.9  ×  10−5 mol · s−1 · m−2 · Pa−1 and a water vapor/nitrogen selectivity higher than 1  ×  104, surpassing that of conventional polymer and graphene oxide‐based membranes. These results demonstrate the potential of Al2O3‐functionalized CNMs for advanced applications in gas separation and air dehumidification.

Since 2005, The Nature and Biodiversity Conservation Union (NABU, Germany) has called upon people in Germany to count birds in their gardens during a defined time (Friday to Sunday) in May. This “Stunde der Gartenvögel” (hour of the garden birds) aims at obtaining a yearly overview of the birds in villages and towns. While this birdwatching action gives a broad overview due to the large number of gardens and parks involved (around 40,000 in the year 2024), several drawbacks must be mentioned that may impede the comparability of the counted bird numbers from one year to another. Here we give an overview of the chronological development of the overall numbers of species and specifically of the most frequent garden birds. We discuss correlations with external factors, such as weather and numbers of participants, and compare the results with ornithological studies in the same period as well as with the results of the yearly Birdrace in Germany, where ornithologically interested people count birds in a defined area on the full first Saturday in May. The main drawback of the citizen science project was found to be misidentifications of birds, especially evident in the case of the Tree Sparrow, combined with birds not being recorded because they could not be identified. The main advantage, on the other hand, is the large amount of data from the “Stunde der Gartenvögel”, which is important for measuring especially the trends of well-known, frequent species much better than the Birdrace. Ideally, all data taken in different ways should be combined, and misinterpretations should be reduced by showing male and female birds of species with strong gender dimorphism.

Zusammenfassung Hintergrund Der digitale Wandel beeinflusst die Prävention und Gesundheitsförderung insbesondere für Menschen in benachteiligten Lebenslagen. Digitale Gesundheitskompetenz ist notwendig, um gesundheitsrelevante Informationen in Bezug auf digitale Anwendungen und Informationsangebote zu finden, zu verstehen, zu beurteilen und anzuwenden. Zielgruppengerechte Angebote zur Förderung der digitalen Gesundheitskompetenz bei benachteiligten Bevölkerungsgruppen sind rar. Ziel des Workshops während der 58. Jahrestagung der DGSMP war es, Herausforderungen und Potenziale der Förderung digitaler Gesundheitskompetenz bei benachteiligten Gruppen zu identifizieren und interdisziplinäre Ansätze zu diskutieren. Methode Der Workshop kombinierte interaktive Methoden wie Perspektivwechsel und Zukunftswerkstatt, um verschiedene Sichtweisen und Lösungsansätze zu erarbeiten. Teilnehmende aus unterschiedlichen Fachbereichen diskutierten entlang problembasierter Beispielszenarien spezifische Herausforderungen für unterschiedliche Zielgruppen. Ergebnisse Für Menschen mit zugeschriebener geistiger Behinderung zeigte sich die Notwendigkeit, digitale Angebote an ihre Fähigkeiten anzupassen und einfache, zugängliche Plattformen zu entwickeln. Für ältere Menschen/Pflegebedürftigen wurden ethische Fragen und die Notwendigkeit, Technologie verständlich zu machen, diskutiert. Für Schüler:innen zeigte sich die Dringlichkeit, Medienkompetenz in den Schulalltag zu integrieren, um Fehlinformationen entgegenzuwirken und gesunde Entscheidungen zu fördern. Die Diskussionen betonten die Bedeutung von spezifischen, auf die jeweilige Zielgruppe zugeschnittenen Maßnahmen. Schlussfolgerungen Ein Community-orientierter Ansatz, der Menschen in ihren spezifischen Lebenskontexten anspricht, wurde als effektiv hervorgehoben. Die Ergebnisse unterstreichen die Notwendigkeit, digitale Gesundheitsangebote und Kompetenzförderung zielgruppenspezifisch zu gestalten. Es bedarf weiterer Forschung und praktischer Erprobung von Konzepten, die sowohl digitale als auch präsentische Elemente integrieren, um die Gesundheitskompetenz effektiv zu stärken und alle Bevölkerungsgruppen adäquat zu unterstützen.

The MaterialDigital initiative represents a major driver toward the digitalization of material science. Next to providing a prototypical infrastructure required for building a shared data space and working on semantic interoperability of data, a core focus area of the Platform MaterialDigital (PMD) is the utilization of workflows to encapsulate data processing and simulation steps in accordance with findable, accessible, interoperable, and reusable principles. In collaboration with the funded projects of the initiative, the workflow working group strives to establish shared standards, enhancing the interoperability and reusability of scientific data processing steps. Central to this effort is the Workflow Store, a pivotal tool for disseminating workflows with the community, facilitating the exchange and replication of scientific methodologies. This article discusses the inherent challenges of adapting workflow concepts, providing the perspective on developing and using workflows in the respective domain of the various funded projects. Additionally, it introduces the Workflow Store's role within the initiative and outlines a future roadmap for the PMD workflow group, aiming to further refine and expand the role of scientific workflows as a means to advance digital transformation and foster collaborative research within material science.

Background/Objectives: Plyometrics is a widely used method to enhance the physical performance of athletes. Studies have demonstrated that the effectiveness of plyometrics increases when combined with other training methods. This study aims to determine whether the direct combination of plyometric and sprint training improves linear sprint speed and change-of-direction speed in youth soccer players. Methods: Twenty-eight male youth soccer players were randomly assigned to an intervention group (INT, n = 14, 12.9 ± 0.4 years) and a control group (CON, n = 14, 12.9 ± 0.7 years). The INT group performed two sessions per week, each including nine drop jumps, followed by a hurdle jump and one sprint. The CON group only performed nine sprints without any jumps. Both groups continued their regular soccer training over the 20-week intervention period. Pre- and post-intervention tests included 5 m, 10 m, and 30 m linear sprints and a modified agility t-test for change-of-direction speed. Results: Largest improvements were observed in the INT group (5 m = 6.7%, 10 m = 4.8%, 30 m = 2.7%, change-of-direction speed = 3.6%, 3.1%). A significant difference between the groups was noted for the 10 m sprint distance (p = 0.02). Furthermore, moderate to large correlations between linear sprint speed and change-of-direction speed were found in both groups (r = 0.33–0.82). Conclusions: Results suggest that the direct combination of plyometric training and sprint training over a 20-week period can improve both linear sprint speed and change-of-direction speed in youth soccer players, thus enhancing physical performance.

Zusammenfassung: Dieser Beitrag untersucht anhand einer Sekundärauswertung der bundesweiten TrEiKo-Trägerbefragung den Zusammenhang zwischen Steuerungsstilen von Kita-Trägern und der Umsetzung struktureller Veränderungen, die als Indikatoren für Organisationsentwicklungsprozesse interpretiert werden. Mittels Clusteranalyse werden drei Steuerungsstile identifiziert, die auf Basis von Mintzbergs Strukturkonfigurationen als „professionelle Bürokratie“, „Adhokratie“ und „Maschinenbürokratie“ klassifiziert werden. Die Ergebnisse zeigen, dass Träger, die eine zentralisierte Steuerung („Maschinenbürokratie“) bevorzugten, häufiger strukturelle Veränderungen vornahmen, während Träger mit partizipativen Ansätzen („professionelle Bürokratie“, „Adhokratie“) seltener solche Veränderungen umsetzten. Dies deutet auf ein mögliches Spannungsfeld zwischen Agilität und Nachhaltigkeit hin.

In Kap. 6 wird die Sorgearbeit von Mädchen diskutiert. Mädchen sind durch ihre Verhütungsarbeit in Care-Ökonomien auf der Herrschaftsebene eingebunden. Auf der symbolischen Ebene zeigt sich eine unterschiedliche Bedeutung von Verhütungsmitteln in Relation zum Alter. Auf der Ebene der Geschlechtersozialisation liegt das Bestimmungsmoment der Sorge: Das Austarieren von divergenten Anforderungen (Ambitendenz) als unsichtbare Sorgearbeit, die Mädchen bereits in ihrer Jugend verrichten.

In Kap. 3 werden die fünf Analysedimensionen der Geschlechterordnung nach Gudrun-Axeli Knapp als heuristischer Horizont herangezogen. Dadurch wird deutlich, dass Sorgetheorien auf verschiedenen Analyseebenen operieren: Care- und Sorge-Arbeit wird innerhalb der Geschlechtersoziologie sowohl unter einer feministisch-marxistischen als auch soziokulturellen Perspektive theoretisiert. Durch dieses Vorgehen wird die Fragestellung der vorliegenden Studie verdichtet und präzisiert.
