Optimising the performance of electrocatalysts requires atomic-scale information, but it is difficult to obtain. Here, we use atom probe tomography to elucidate the 3D structure of 10 nm sized Co2FeO4 and CoFe2O4 nanoparticles during oxygen evolution reaction (OER). We reveal nanoscale spinodal decomposition in pristine Co2FeO4. The interfaces of Co-rich and Fe-rich nanodomains of Co2FeO4 become trapping sites for hydroxyl groups, contributing to a higher OER activity compared to that of CoFe2O4. However, the activity of Co2FeO4 drops considerably due to concurrent irreversible transformation towards CoIVO2 and pronounced Fe dissolution. In contrast, there is negligible elemental redistribution for CoFe2O4 after OER, except for surface structural transformation towards (FeIII, CoIII)2O3. Overall, our study provides a unique 3D compositional distribution of mixed Co-Fe spinel oxides, which gives atomic-scale insights into active sites and the deactivation of electrocatalysts during OER.","lang":"eng"}],"publication":"Nature Communications","keyword":["electrocatalysis","oxygen evolution reaction","cobalt spinel","electrochemical impedance spectroscopy"],"language":[{"iso":"eng"}]},{"publication":"Journal of Materials Chemistry A","abstract":[{"lang":"eng","text":"Nanostructured manganese oxides have a rich variety of morphologies and crystal phases which can undergo transformations during synthesis and application. Although these structural features are crucial for their performance, the mechanisms behind such transitions are not well understood. Herein, we describe the mechanism of transformation from layered 2D δ-MnO2 nanosheets to the scarcely reported γ-MnO2 nanocone morphology. Despite the common purpose of introducing Fe dopants to enhance the conductivity of layered manganese oxides, the Fe galvanic exchange reaction was found responsible for such coupled phase/morphology transition. Electrochemical characterization confirmed a distinct electrochemical behaviour of the nanocones, emphasizing the need to unravel the mechanism of 2D MnO2 transformation. Such mechanistic insights were gained by systematic and rigorous electron microscopy studies. The effect of the local chemical composition was determined by energy dispersive X-ray spectroscopy while electron energy loss spectroscopy unravelled the key influence of the oxidation state of Mn ions within nanosheets and nanocones. We propose and demonstrate a Mn2+-mediated oxidative mechanism of coupled morphology/phase transformation subjected to the equilibrium of Fe and Mn ions during galvanic exchange reaction. These findings contribute to the understanding of the growth and morphology/phase transformations of manganese oxide nanostructures, providing insights for the rational design of nanomaterials."}],"keyword":["manganese oxide","nanomaterials","TEM","supercapacitors"],"language":[{"iso":"eng"}],"quality_controlled":"1","issue":"45","year":"2022","publisher":"Royal Society of Chemistry (RSC)","date_created":"2025-12-03T16:02:15Z","title":"Mechanism of coupled phase/morphology transformation of 2D manganese oxides through Fe galvanic exchange reaction","type":"journal_article","status":"public","_id":"62813","user_id":"116779","department":[{"_id":"985"}],"article_type":"original","extern":"1","publication_status":"published","publication_identifier":{"issn":["2050-7488","2050-7496"]},"citation":{"ama":"Aymerich-Armengol R, Cignoni P, Ebbinghaus P, et al.

These preprocessor directives, however, challenge any static code analysis. SPLlift, a previously presented approach for analyzing software product lines, is limited to Java programs that use a rather simple feature encoding and to analysis problems with a finite and ideally small domain. Other approaches that allow the analysis of real-world C software product lines use special-purpose analyses, preventing the reuse of existing analysis infrastructures and ignoring the progress made by the static analysis community. This work presents <jats:sc>VarAlyzer</jats:sc>, a novel static analysis approach for software product lines. <jats:sc>VarAlyzer</jats:sc> first transforms preprocessor constructs to plain C while preserving their variability and semantics. It then solves any given distributive analysis problem on transformed product lines in a variability-aware manner. <jats:sc>VarAlyzer</jats:sc> ’s analysis results are annotated with feature constraints that encode in which configurations each result holds. Our experiments with 95 compilation units of OpenSSL show that applying <jats:sc>VarAlyzer</jats:sc> enables one to conduct inter-procedural, flow-, field- and context-sensitive data-flow analyses on entire product lines for the first time, outperforming the product-based approach for highly-configurable systems.</jats:p>"}],"publication":"Automated Software Engineering","language":[{"iso":"eng"}],"keyword":["inter-procedural static analysis","software product lines","preprocessor","LLVM","C/C++"]},{"type":"book_chapter","publication":"Wissenstransfer.

In this study, a variety of electron polarons, namely free, bound, and bipolarons, are analyzed using first-principles calculations. We perform a full structural optimization based on density-functional theory for selected intrinsic defects with special attention to the role of symmetry-breaking distortions that lower the total energy. The cations hosting the various polarons relax to a different degree, with a larger relaxation corresponding to a larger gap between the defect level and the conduction-band edge. The projected density of states reveals that the polaron states are formerly empty Nb 4d states lowered into the band gap. Optical absorption spectra are derived within the independent-particle approximation, corrected by the GW approximation that yields a wider band gap and by including excitonic effects within the Bethe-Salpeter equation. Comparing the calculated spectra with the density of states, we find that the defect peak observed in the optical absorption stems from transitions between the defect level and a continuum of empty Nb 4d states. Signatures of polarons are further analyzed in the reflectivity and other experimentally measurable optical coefficients."}]},{"publication":"Higher Education","abstract":[{"lang":"eng","text":"In Germany, dual learning programmes are increasingly offered by higher education institutions. These programmes’ main characteristic and greatest challenge is their integration of academic and vocational learning. So far, this challenge has frequently been stated without specifying its exact nature and consequences for learners. The present study addresses this pedagogical research gap and examines the extent of variation in the degree of integration among dual study programmes. With reference to curriculum theory, the study develops an empirical typology of curricular integration in dual programmes. The data sample consists of 152 programmes at (dual) universities and universities of applied sciences. Data is analysed using hierarchical cluster analysis. Results indicate that the currently prevailing forms of curricular integration should best be differentiated according to five types. The five overlapping types of integration are located on a continuum ranging from parallelism through organisational linking to full curricular integration targeted immediately at students’ personal integration. The analysis confirms that there are problems with complying with integration standards set on the policy level. Above all, the study offers new insights on what marks the diverse integration landscape of dual study programmes. It proves that approaches to integration are more differentiated than previous research has shown."}],"language":[{"iso":"eng"}],"keyword":["Dual study programmes · Curricular integration · Curriculum theory · Empirical typology · Cluster analysis · Germany"],"issue":"6","quality_controlled":"1","year":"2022","date_created":"2023-10-05T09:25:30Z","publisher":"Springer Science and Business Media LLC","title":"Curricular integration of academic and vocational education: a theory-based empirical typology of dual study programmes in Germany","type":"journal_article","status":"public","department":[{"_id":"282"},{"_id":"208"},{"_id":"640"}],"user_id":"71994","_id":"47627","article_type":"original","publication_identifier":{"issn":["0018-1560","1573-174X"]},"publication_status":"published","intvolume":"        85","page":"1257-1279","citation":{"chicago":"Mordhorst, Lisa, and Tobias Jenert. “Curricular Integration of Academic and Vocational Education: A Theory-Based Empirical Typology of Dual Study Programmes in Germany.” <i>Higher Education</i> 85, no. 6 (2022): 1257–79. <a href=\"https://doi.org/10.1007/s10734-022-00889-7\">https://doi.org/10.1007/s10734-022-00889-7</a>.","ieee":"L.

However, the material dispersion of integrated platforms constitutes an obstacle that limits the performance and precision of such interferometers. At the same time, two-colour nonlinear interferometers present an important tool for metrological applications, when measurements in a certain frequency range are difficult. In this manuscript, we theoretically developed and investigated an integrated multimode two-colour SU(1,1) interferometer operating in a supersensitive mode. By ensuring the proper design of the integrated platform, we suppressed the dispersion, thereby significantly increasing the visibility of the interference pattern. The use of a continuous wave pump laser provided the symmetry between the spectral shapes of the signal and idler photons concerning half the pump frequency, despite different photon colours. We demonstrate that such an interferometer overcomes the classical phase sensitivity limit for wide parametric gain ranges, when up to 3×104 photons are generated.</jats:p>","lang":"eng"}],"department":[{"_id":"15"},{"_id":"569"},{"_id":"170"},{"_id":"429"},{"_id":"230"},{"_id":"9"},{"_id":"27"}],"user_id":"16199","_id":"40371","project":[{"name":"TRR 142: TRR 142","_id":"53"},{"_id":"56","name":"TRR 142 - C: TRR 142 - Project Area C"},{"name":"TRR 142 - C2: TRR 142 - Subproject C2","_id":"72"},{"_id":"52","name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"language":[{"iso":"eng"}],"keyword":["Physics and Astronomy (miscellaneous)","General Mathematics","Chemistry (miscellaneous)","Computer Science (miscellaneous)"],"article_number":"552"}]
