Using qualitative content analysis, the study summarizes how coopetition is calibrated, what results it produces, and what challenges are associated with it. The resulting Data Ecosystem Coopetition (DECo) model specifies four management levers, as well as the associated outcomes and common challenges. In addition, six cycles were identified that link levers, challenges, and outcomes.

The aim is to determine the relevant range of punch velocities based on material properties, such as strain rate dependence, and to assess whether punch velocity can be utilized as a control variable for versatile joining processes. To this aim, similar joints made of steel (HCT590X+Z), aluminum (EN AW-6014), and mixed joints of these materials are examined. The resulting joining forces are analyzed using force-displacement curves to evaluate the influence on the joining process. The form closure is examined using micrographs of the joints' geometric parameters.

Alternatively, semiconductor surface chemistry can enable O2 detection. However, these approaches are often limited by slow response and recovery times and low selectivity, restricting their practical applications. The metal-organic framework MOF-76(Eu) and its yttrium-modified variant, MOF-76(Eu/Y) are reported to exhibit highly reversible and fast optical responses to varying O2 concentrations. Time-resolved emission measurements are performed over short (seconds) and long (hours) timescales using N2 and synthetic air mixtures. Cross-sensitivity to humidity is analyzed. Multichannel scaling photon-counting experiments confirm quenching at the linker level, as the emission lifetime remains nearly constant. Yttrium significantly improves stability and performance at room temperature. Structural and optical changes induced by yttrium are investigated.

Despite a substantial amount of research on pupils’ basic psychological needs for autonomy, competence and social relatedness (Ryan et al., 2022), strategies that technology education teachers apply in this regard are not yet well understood. Besides interventional studies on technology education, indicating effectiveness of self‑directed and action‑oriented teaching and learning, there is a dearth of research on how teachers address different needs as a routine. The purpose of the presented study is therefore to investigate and systematize actions and strategies teachers apply, and to specify how pupils' needs are considered when teaching technology education on a given topic. The overall study used a mixed-methods approach to the question how pupils’ needs are characterized by themselves and by their teachers, and how they were taken into account in a lesson adapted and delivered by the teachers. In the sub-study presented here, participating primary school teachers were interviewed about their consideration of pupils’ needs whilst planning and conducting a technology education unit on the functionality of robots. The results gained from qualitative content analysis of the interviews indicate that although the anticipation of different needs is considered challenging, teachers possess a substantiate amount of practices and strategies to take them into account.

By immobilizing the glycopeptide antibiotic vancomycin on DONs, DON binding to Gram‐positive and Gram‐negative bacteria can be facilitated. Here, we investigate how this multivalent binding is affected by the number and arrangement of the vancomycin modifications on two‐dimensional DONs. We find that for both Gram‐positive Bacillus subtilis and Gram‐negative Escherichia coli , binding increases with the number of vancomycin modifications per DON. In general, binding to E. coli is stronger than to B. subtilis , which may be attributed to differences in the architectures of the cell envelopes. Interestingly, for both bacteria, the total number of vancomycin modifications appears to be more important than their arrangement, as DONs with 18 vancomycin molecules on one side show similar binding as DONs with 18 vancomycin molecules distributed over both sides. This enables the attachment of multiple probe molecules to the vancomycin‐free side of the DONs for enhancing detection efficiency without compromising binding affinity. These results may thus provide guidelines for the design and synthesis of vancomycin‐modified DONs for antimicrobial drug delivery and pathogen detection. }}, author = {{Coşkuner Leineweber, Özge and Hofmann, Ulrike and Grundmeier, Guido and Zhang, Yixin and Keller, Adrian Clemens}}, issn = {{1439-4227}}, journal = {{ChemBioChem}}, number = {{13}}, publisher = {{Wiley}}, title = {{{Vancomycin‐Mediated Binding of DNA Origami Nanostructures to Gram‐Positive and Gram‐Negative Bacteria}}}, doi = {{10.1002/cbic.70436}}, volume = {{27}}, year = {{2026}}, }
