However, the spectral information in CARS is often hampered by the presence of a nonresonant contribution to the scattering process that shifts and distorts the Raman peaks. In this work, we apply a method to obtain nonresonant background-free spectra based on time-delayed, broadband CARS (TD-BCARS) using an intrapulse excitation scheme. In particular, this method can measure the phononic dephasing times across the full phonon spectrum at once. We test the methodology on amorphous SiO2 (glass), which is used to characterize the setup-specific and material-independent response times, and then apply TD-BCARS to the analysis of single crystals of diamond and ferroelectrics of potassium titanyl phosphate (KTP) and potassium titanyl arsenate (KTA). For diamond, we determine a dephasing time of 𝜏=7.81 ps for the single 𝑠⁢𝑝3 peak.}}, author = {{Hempel, F. and Rüsing, Michael and Vernuccio, F. and Spychala, K.

However, in academic teacher education programmes often use assessment formats that are not well aligned with the demands of teachers' actual professional practice. Performance-based assessments can offer an alternative, for example in the form of role-play-based simulations with trained actors representing typical professional activities in environments of reduced complexity. We have developed such a performance-based assessment format for physics teacher education, analogous to the Objective Structured Teaching Examinations (OSTE) approach used in medical education. The OSTE prototype consists of seven short simulative assessments, reflecting four areas of competence (Instruction, Assessment, Pedagogy and Innovation) that form a 90-minute examination course. In order to investigate prospective physics teachers' perceptions of such an assessment format in terms of its suitability as a summative examination procedure, we piloted the OSTE prototype with N = 34 physics student teachers from three German universities using short questionnaires. The results show that participants perceived the OSTE prototype as authentic and relevant, but they also highlight the need for adequate new learning opportunities to prepare for such simulative examinations to be integrated into teacher education programmes.}}, author = {{Vogelsang, Christoph and Grotegut, Lea and Wotschel, Philipp and Janzen, Thomas}}, keywords = {{teacher education, physics, assessment, pre-service teachers}}, location = {{Copenhagen}}, title = {{{Prospective Physics Teachers' Perceptions of an Objective Structured Teaching Examination (OSTE)}}}, year = {{2025}}, } @inproceedings{62756, author = {{Janzen, Thomas and Wotschel, Philipp and Grotegut, Lea and Vogelsang, Christoph}}, location = {{Kassel}}, title = {{{„als Student hätte ich da mehr Bock drauf als auf eine [Fachdidaktikklausur]“ - Die Wahrnehmung von Studierenden hinsichtlich rollenspielbasierter Simulationen als handlungsorientiertes Prüfungsformat für die Englischlehrkräftebildung}}}, year = {{2025}}, } @inproceedings{62753, author = {{Janzen, Thomas and Grotegut, Lea and Wotschel, Philipp and Vogelsang, Christoph}}, location = {{Mannheim }}, title = {{{Validierung einer rollenspielbasierten Simulationsprüfung für angehende Englischlehrkräfte- Validitätsargumente zum Scoring und zur Testwertinterpretation}}}, year = {{2025}}, } @inproceedings{62754, author = {{Vogelsang, Christoph and Wotschel, Philipp and Janzen, Thomas and Grotegut, Lea}}, location = {{Heilbronn}}, title = {{{Auf die Prüfung kommt es an! - Handlungsnahe Prüfungsformate in Lehramtsstudiengängen}}}, year = {{2025}}, } @inproceedings{62757, author = {{Vogelsang, Christoph and Wotschel, Philipp and Janzen, Thomas and Grotegut, Lea}}, location = {{Essen}}, title = {{{Das Handeln prüfen - Performanzorientierte Prüfungsformate im Lehramtsstudium}}}, year = {{2025}}, } @article{60509, author = {{Vogelsang, Christoph and Scholl, Daniel and Meier, Jana and Küth, Simon}}, journal = {{Education Sciences}}, number = {{7}}, title = {{{Thoughts Are Free—Differences Between Unstructured and Structured Reflections of Teachers with Different Levels of Expertise}}}, doi = {{https://doi.org/10.3390/educsci15070820}}, volume = {{15}}, year = {{2025}}, } @article{62765, author = {{Strauß, Sara}}, issn = {{0947-0034}}, journal = {{Anglistik: International Journal of English Studies}}, number = {{1}}, pages = {{5--14}}, title = {{{Introduction: Irish Communities in a Glocal Context – Literary and Cultural Narratives}}}, doi = {{https://doi.org/10.33675/ANGL/2025/1/4}}, volume = {{36}}, year = {{2025}}, } @article{62798, abstract = {{We investigated electrodeposited nanoparticulate nickel selenide (pre)catalysts that transform into nickel oxides/oxyhydroxides under oxygen evolution reaction conditions in alkaline solutions. Previous studies of this transformation were conducted at lower current densities than those of industrial relevance (≥1 A cm–2). We used ultramicroelectrodes (UMEs) to achieve such current densities, benefiting from their small size, ensuring low absolute currents and low ohmic drop but high current densities. Morphological degradation of the catalyst material was only observed at current densities exceeding 1 A cm–2 but not for smaller ones. Using X-ray absorption, X-ray photoemission spectroscopy, and X-ray diffraction, we confirmed that the degradation was accompanied by the literature-known transformation of nanoparticulate Ni3Se2 (bulk)/NiSe (surface) into nickel oxyhydroxide. The transformation of the precatalyst goes along with a significant improvement in the charge transfer kinetics observed by decreasing Tafel slopes with ongoing experimental time extracted from cyclic voltammetry (CV) experiments and electrochemical impedance spectroscopy (EIS) in the high-frequency range. However, these kinetic improvements are accompanied by limitations in mass transport concluded from decreasing current responses at high overpotentials in CVs and increasing impedance in the low-frequency range of the EIS spectra after extended CV cycling. These mass transport limitations originated from morphological degradations at the UME exceeding 1 A cm–2 which we proved by applying identical location scanning electron microscopy. This has not been reported in studies that have been limited to lower current densities before. Our findings showcase how UMEs can be used to study (pre)catalysts (herein nickel selenides) under current densities of industrial relevance in the absence of ohmic drop-related ambiguities, combined with in-depth materials characterization studies, e.g., identical location microscopy and advanced spectroscopic methods. This approach enables direct evaluation and comparison of catalyst materials and thus demonstrates how to overcome long-standing limitations of electrocatalyst design and testing.}}, author = {{Hiege, Felix and Chang, Chun-Wai and Trost, Oliver and van Halteren, Charlotte E.

The isostructural heterometallic complex salts were characterized by single-crystal and powder X-ray diffraction, infrared and impedance spectroscopy, thermal analysis and magnetization measurements. The trinuclear anion [{Mn(bpy)(H2O)Cl(μ-C2O4)}2Cr(C2O4)]− consists of two [Mn(bpy)(H2O)Cl]+ units bridged by the [Cr(C2O4)3]3− anion, which acts as a bidentate ligand towards each of the manganese atoms. The anions are hydrogen bonded to each other via coordinated chloride anions, water molecules and oxygen oxalate atoms, resulting in two-dimensional (2D) hydrogen bonding layers. Compounds exhibit water-assisted proton conductivity behaviour, which was investigated at different temperatures and relative humidities (RH). At 25 °C, an increase in RH from 60% to 93% resulted in an obvious proton conducting switch from 9.1 × 10−11 to 5.6 × 10−5 S cm−1 for 1 and from 7.4 × 10−10 to 1.8 × 10−6 S cm−1 for 2, corresponding to high on/off ratios of about 106 for 1 and 104 for 2. In situ powder X-ray diffraction (PXRD) analysis showed that unit cell parameters of compounds 1 and 2 slightly increase when exposed to humid conditions. This confirmed that incorporation of water molecules into structures with pores and voids causes the proton conductivity switching phenomenon. Magnetic susceptibility measurements indicate a ferromagnetic interaction between Cr3+ and Mn2+ ions bridged by the bis(bidentate) oxalate group. The prepared compounds 1 and 2 were explored as single-source precursors for the formation of spinel oxide by their thermal treatment. With increasing temperature, the spinel composition changed according to the formula Mn1+xCr2–xO4 (0 ≤ x ≤ 1), where x = 0.7 at 500 °C and x = 1 at 900 °C when tet[MnII]oct[MnIIICrIII]O4 is formed. The (micro)structure, morphology, and optical properties of spinel Mn2CrO4 were characterized by PXRD, scanning electron microscopy and UV-Vis diffuse reflectance spectroscopy. The photocatalytic activity of this oxide in degradation of the methylene blue dye under Vis irradiation without and with the support of hydrogen peroxide was further investigated.}}, author = {{Lozančić, Ana and Burazer, Sanja and Wagner, Tobias and Molčanov, Krešimir and Pajić, Damir and Androš Dubraja, Lidija and Tiemann, Michael and Jurić, Marijana}}, issn = {{2050-7526}}, journal = {{Journal of Materials Chemistry C}}, number = {{41}}, pages = {{21179--21195}}, publisher = {{Royal Society of Chemistry (RSC)}}, title = {{{Water-assisted proton conductivity and a magnetic study of heterotrinuclear oxalate-bridged compounds: molecular precursors for the Mn2CrO4 spinel}}}, doi = {{10.1039/d5tc02569a}}, volume = {{13}}, year = {{2025}}, } @inproceedings{62818, author = {{Radtke, Sabine}}, editor = {{Belalcazar, Catalina}}, keywords = {{Sports Coaching, Diversity, Intersectionality}}, location = {{Athens}}, number = {{S1}}, pages = {{S4}}, publisher = {{Human Kinetics}}, title = {{{Ethical dilemmas in coaching: Diversity and inclusion and the role of the coach}}}, doi = {{https://doi.org/10.1123/iscj.2025-0112}}, volume = {{12}}, year = {{2025}}, } @article{62179, author = {{Koch, Leon and Baier, Dominik and Rajput, Satyendra and König, Benedikt and Tiemann, Michael and Ebbinghaus, Simon and Nayar, Divya and Huber, Klaus}}, issn = {{1520-6106}}, journal = {{The Journal of Physical Chemistry B}}, number = {{40}}, pages = {{10213--10228}}, publisher = {{American Chemical Society (ACS)}}, title = {{{Disaggregation at High Volume Exclusion: An “Overcrowding” Effect}}}, doi = {{10.1021/acs.jpcb.5c01245}}, volume = {{129}}, year = {{2025}}, } @inproceedings{60637, author = {{Weiser, David and Ditter, Rebecca and Ditter, David and Siepmann, Karin and Grandrath, Rebecca and Fechner, Sabine and Sommer, Katrin and Bohrmann-Linde, Claudia and Rubner, Isabel}}, booktitle = {{International conference New Perspective on Science Education}}, isbn = {{979-12-80225-83-2}}, location = {{Florence}}, number = {{14}}, publisher = {{Libreriauniversitaria.it}}, title = {{{Innovative teaching with actionbound: Digital pathways in chemistry education - a practical example from ComeNet Chemistry in the ComeMINT Project}}}, year = {{2025}}, } @inbook{61474, author = {{Habig, Sebastian and Großmann, Nadine and Schmid, Andrea M. and van Vorst, Helena and Fechner, Sabine and Wilde, Matthias}}, booktitle = {{Interesse revisited}}, isbn = {{9783658485412}}, publisher = {{Springer Fachmedien Wiesbaden}}, title = {{{Empirische Befunde der Interessenforschung der Fächer Biologie, Chemie und Physik im Primar- und Sekundarbereich seit 2012 – Ein systematisches Review}}}, doi = {{10.1007/978-3-658-48542-9_4}}, year = {{2025}}, } @inbook{61475, author = {{Zöchling, Sarah and Pletschacher, Laura and Maurer, Christian and Berger, Roland and Lindmaier, Kerstin and Fechner, Sabine and Wodzinski, Rita}}, booktitle = {{Interesse revisited}}, isbn = {{9783658485412}}, publisher = {{Springer Fachmedien Wiesbaden}}, title = {{{Interessenförderung im Physik- und Chemieunterricht – Eine Bestandsaufnahme}}}, doi = {{10.1007/978-3-658-48542-9_10}}, year = {{2025}}, } @article{62794, author = {{Hansmeier, Philipp and Althaus, Maike}}, journal = {{Journal of Service Management Research}}, number = {{2}}, title = {{{Visitor Revival Propositions for Cultural Institutions – A Service Science Perspective}}}, year = {{2025}}, } @inproceedings{60126, author = {{Hansmeier, Philipp and Schäfer, Jannika Marie}}, booktitle = {{Thirty-Third European Conference on Information Systems}}, location = {{Amman}}, title = {{{ARTIFICIAL INTELLIGENCE IN DIGITAL SERVICE ECOSYSTEMS – A TAXONOMY APPROACH}}}, year = {{2025}}, } @inproceedings{60127, author = {{Hansmeier, Philipp}}, booktitle = {{Thirty-Third European Conference on Information Systems}}, title = {{{CONCEPTUALIZING A CUSTOMER EXPERIENCE FRAMEWORK FOR HYBRID (PHYSICAL-DIGITAL) SERVICE ECOSYSTEMS}}}, year = {{2025}}, }
