Diese sind in der Lage, umfangreiche Daten während ihres Betriebs zu sammeln und über digitale Netzinfrastrukturen zur Verfügung zu stellen. Gemeinsam mit weiteren Daten aus der Betriebsphase versprechen sie wertvolle Erkenntnisse über das Produkt und dessen Nutzer, welche für die Hersteller der CPS insbesondere für die Planung zukünftiger Produktgenerationenrelevant sind. Die zielgerichtete Nutzung von Betriebsdaten in der strategischen Produktplanung stellt produzierende Unternehmen jedoch noch vor zahlreiche Herausforderungen, z. B. hinsichtlich der Identifizierung Erfolg versprechender Use Cases. Das vorliegende Buch greift diese Herausforderungen auf und stellt ein Instrumentarium vor, das produzierende Unternehmen zur datengestützten Produktplanung befähigt. Neben der Vorstellung praxiserprobter Methoden und Werkzeuge werden Einblicke in vier Pilotprojekte gegeben. Das Instrumentarium entstand im Forschungsprojekt „DizRuPt“, das vom Bundesministerium für Bildung und Forschung (BMBF) gefördert wurde.","lang":"eng"}],"place":"Paderborn","date_created":"2023-11-07T14:11:00Z","department":[{"_id":"563"}],"type":"book_editor"},{"citation":{"apa":"Mombeck, M.

At the same time, the biggest challenge in education systems worldwide is the social inclusion of students. In a pre–post design, 30 heterogeneous students (16 f/14 m) from four different school classes (grades 5–8) of two secondary schools and one grammar school were interviewed (in a problem-centered interview) about their social inclusion and their social climate in class before and after being taught selected subjects with a school dog for one school term. At the second measurement point, participants were also asked about their perception of animal-assisted pedagogy. The qualitative data analysis (Kuckartz) showed that the presence of a dog leads to an improved social climate, more social integration and to a change in social roles; therefore, we discussed our findings in the context of role theory (Krappmann). In addition, we found that the mutual perception of the other students and the teacher changes to a more positive and friendlier image. Through animal-assisted pedagogy, a new social role is added to the classroom, where caring and bonding are prioritized. Social interaction and norms are influenced and stereotypical and individual roles can be changed. Therefore, animal-assisted pedagogy can be key to promoting social inclusion in the school environment.</jats:p>"}],"date_created":"2024-05-28T08:25:29Z","type":"journal_article","year":"2023","title":"The Impact of a School Dog on Children’s Social Inclusion and Social Climate in Class","author":[{"full_name":"Mombeck, Mona Maria","first_name":"Mona Maria","last_name":"Mombeck","id":"29268"},{"first_name":"Timm","last_name":"Albers","full_name":"Albers, Timm"}],"publication_identifier":{"issn":["2254-9625"]},"publication_status":"published","date_updated":"2026-01-20T15:16:30Z","intvolume":"        14","language":[{"iso":"eng"}],"doi":"10.3390/ejihpe14010001"},{"project":[{"_id":"53","name":"TRR 142: TRR 142 - Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen"},{"name":"TRR 142 - C: TRR 142 - Project Area C","_id":"56"},{"name":"TRR 142 - C10: TRR 142 -  Erzeugung und Charakterisierung von Quantenlicht in nichtlinearen Systemen: Eine theoretische Analyse (C10*)","_id":"174"},{"_id":"52","name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"citation":{"chicago":"Scharwald, Dennis, Torsten Meier, and Polina Sharapova. “Phase Sensitivity of Spatially Broadband High-Gain SU(1,1) Interferometers.” <i>Physical Review Research</i> 5, no. 4 (2023). <a href=\"https://doi.org/10.1103/physrevresearch.5.043158\">https://doi.org/10.1103/physrevresearch.5.043158</a>.","ama":"Scharwald D, Meier T, Sharapova P.

This leads to the insight that an autoethnographic approach may be a much better fit for such an experience, where complex and inexpressible things can be found. This is especially the case since autoethnographic texts include and immerse the reader in the experience. Even though in the case of meditation this can hardly be achieved, this quadrologue aims at conveying some of the struggles and peculiarities of meditation practice. It focuses on the research process leading to the decision to employ an autoethnography paradigm. Thus, the focus of this article is the differentiation of autoethnography from other methodological approaches and the conscious decision in favour of this method, which is rather unusual in German-speaking countries. The authors develop the thesis that both the meditation experience and the decision to employ an autoethnographic paradigm led to the experience of “wandering off the beaten track” and crossing the boundaries of what is usually done in society and social science respectively.</jats:p>","lang":"eng"}],"date_created":"2025-05-25T12:44:13Z","type":"journal_article","title":"Crossing Boundaries: Autoethnography of Subjective Experiences During Meditation","year":"2023","status":"public","author":[{"full_name":"Kothe, Anna-Katharina","first_name":"Anna-Katharina","last_name":"Kothe"},{"id":"95153","full_name":"Vochatzer, Stefanie","last_name":"Vochatzer","first_name":"Stefanie"},{"first_name":"Christian","last_name":"Oesterle","full_name":"Oesterle, Christian"},{"full_name":"Ruf, Steffen Philipp","first_name":"Steffen Philipp","last_name":"Ruf"}],"publication_identifier":{"issn":["2160-3715"]},"publication_status":"published","date_updated":"2026-02-03T10:43:27Z","_id":"60035","language":[{"iso":"eng"}],"publisher":"Nova Southeastern University","user_id":"95153","doi":"10.46743/2160-3715/2023.5510"},{"editor":[{"full_name":"von Elbwart, Katharina","first_name":"Katharina","last_name":"von Elbwart"},{"first_name":"Bernhard","last_name":"Fisseni","full_name":"Fisseni, Bernhard"},{"first_name":"Katja","last_name":"Winter","full_name":"Winter, Katja"},{"full_name":"Wodtke, Eva","last_name":"Wodtke","first_name":"Eva"}],"user_id":"87912","_id":"63387","publisher":"Aschendorff Verlag","language":[{"iso":"eng"}],"date_updated":"2026-02-03T14:37:21Z","author":[{"id":"87912","last_name":"Elbwart","first_name":"Katharina","full_name":"Elbwart, Katharina"},{"full_name":"Winter, Katja","last_name":"Winter","first_name":"Katja"},{"first_name":"Matthias","last_name":"Keidel","full_name":"Keidel, Matthias"}],"year":"2023","title":"Podcasts in der Hochschullehre: mittelalt & literarisch.","status":"public","type":"book_chapter","date_created":"2025-12-19T16:04:39Z","place":"Münster","citation":{"mla":"Elbwart, Katharina, et al. “Podcasts in Der Hochschullehre: Mittelalt &#38; Literarisch.” <i>Beackerte Felder: Kultur, Bildung, Erinnerung.

The cell set-up is suitable for using powder electrode materials. Reproducibility of our cell assembly is analyzed by preparing two cells containing hard carbon (HC) powder as working electrode and sodium metal as reference electrode. Electrochemical storage properties of HC powder electrode derived from carbonization of sustainable cellulose are studied by ssNMR. 23Na in-situ ssNMR monitors the sodiation/desodiation of a Na{\\textbar}NaPF6{\\textbar}HC cell (cell 1) over a period of 22?days, showing high cell stability. After the galvanostatic process, the HC powder material is investigated by high resolution 23Na ex-situ MAS NMR. The formation of ionic sodium species in different chemical environments is obtained. Subsequently, a second Na{\\textbar}NaPF6{\\textbar}HC cell (cell 2) is sodiated for 11?days achieving a capacity of 220?mAh/g. 23Na ex-situ MAS NMR measurements of the HC powder material extracted from this cell clearly indicate the presence of quasi-metallic sodium species next to ionic sodium species. This observation of quasi-metallic sodium species is discussed in terms of the achieved capacity of the cell as well as of side reactions of sodium in this electrode material."}],"extern":"1","publication":"Chemsuschem","doi":"10.1002/cssc.202301300","language":[{"iso":"eng"}],"date_updated":"2026-02-17T16:13:10Z","intvolume":"        17","title":"Electrochemical Sodium Storage in Hard Carbon Powder Electrodes Implemented in an Improved Cell Assembly: Insights from In-Situ and Ex-Situ Solid-State NMR","year":"2023","author":[{"last_name":"Šić","first_name":"Edina","full_name":"Šić, Edina"},{"last_name":"Schutjajew","first_name":"Konstantin","full_name":"Schutjajew, Konstantin"},{"full_name":"Haagen, Ulrich","last_name":"Haagen","first_name":"Ulrich"},{"full_name":"Breitzke, Hergen","first_name":"Hergen","last_name":"Breitzke"},{"first_name":"Martin","last_name":"Oschatz","full_name":"Oschatz, Martin"},{"full_name":"Buntkowsky, Gerd","last_name":"Buntkowsky","first_name":"Gerd"},{"last_name":"Gutmann","first_name":"Torsten","full_name":"Gutmann, Torsten","id":"118165"}],"publication_identifier":{"issn":["1864-5631"]}},{"publication":"Chemsuschem","extern":"1","abstract":[{"lang":"eng","text":"Abstract Polymer-derived silicon oxycarbide ceramics (SiCO) have been considered as potential anode materials for lithium- and sodium-ion batteries.

In this study, we elucidate the mechanism of the propane ODH reaction over VOx/TiO2, using P25 and ALD (atomic layer deposition) synthesized TiO2/SBA-15 as a support, with X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), 51V solid-state (ss)NMR, operando multiwavelength Raman, operando UV–vis, and transient IR spectroscopies. Bare titania shows a small conversion, leading to carbon formation, and the reaction occurs at the interface between anatase and rutile. In comparison, in VOx/TiO2 catalysts, the activity shifts from titania to vanadia sites. UV-Raman spectroscopy and structural characterization data revealed the reaction to involve preferentially the V═O bonds of dimeric species rather than doubly bridged V–O–V bonds, which leads to higher propene selectivities. The active vanadium site shows a nuclearity-dependent behavior; that is, at higher loadings, when oligomeric vanadia is present, it shifts from V═O bonds to linear V–O–V bonds in oligomers, leading to less selective oxidation due to the better reducibility. Our operando/transient spectroscopic results demonstrate the direct participation of the titania support in the reaction by influencing the degree of vanadia oligomerization and enabling rapid hydrogen transfer from propane to vanadia via Ti–OH groups on anatase, accelerating the rate-determining step of the initial C–H bond breakage. The broader applicability of the results is confirmed by the behavior of the ALD-synthesized sample, which resembles that of P25.

Our results highlight the detailed level of mechanistic understanding accessible from multiple spectroscopic approaches, which can be readily transferred to other materials and/or reactions.","lang":"eng"}],"extern":"1","citation":{"chicago":"Schumacher, Leon, Johannes Pfeiffer, Jun Shen, Torsten Gutmann, Hergen Breitzke, Gerd Buntkowsky, Kathrin Hofmann, and Christian Hess. “Collaborative Mechanistic Effects between Vanadia and Titania during the Oxidative Dehydrogenation of Propane Investigated by Operando and Transient Spectroscopies.” <i>ACS Catalysis</i> 13, no. 12 (2023): 8139–8160. <a href=\"https://doi.org/10.1021/acscatal.3c01404\">https://doi.org/10.1021/acscatal.3c01404</a>.","short":"L.

Employing this solvent-free approach allows to minimize the ecological impact of the synthesis by bypassing hazardous wastes, while simultaneously observing the reactions between the individual starting materials separately for the first time. Especially the role of dichloromethane needs to be reconsidered, functioning as a linker between the nitrogen-containing node cyanuric chloride and the aromatic monomer 1,3,5-triphenylbenzene, as proven by X-ray photoelectron spectroscopy and 1H â†’ 13C Cross-Polarization magic-angle-spinning nuclear magnetic resonance spectroscopy. This results in a drastic enhancement of the reaction rate, reducing the synthesis time down to 1 minute. Additionally, this linkage over a C1 bridge enables the incorporation of nitrogen into already synthesized polymers by post polymerization functionalization. The variation of the synthesis building blocks, namely the linker, node, and monomer, results in a variety of nitrogen-containing polymers with specific surface areas of up to 1500 m2 gâˆ’1. Therefore, the presented approach is capable to target the synthesis of various CTNs with a minimal use of chlorinated linker, rendering the concept as a sustainable alternative to the classical solution-based synthesis.","lang":"eng"}]},{"intvolume":"        52","date_updated":"2026-02-17T16:16:51Z","author":[{"last_name":"Hoffmann","first_name":"Markus M.","full_name":"Hoffmann, Markus M."},{"first_name":"Nathaniel P.","last_name":"Randall","full_name":"Randall, Nathaniel P."},{"first_name":"Miray H.","last_name":"Apak","full_name":"Apak, Miray H."},{"first_name":"Nathaniel A.","last_name":"Paddock","full_name":"Paddock, Nathaniel A."},{"id":"118165","full_name":"Gutmann, Torsten","last_name":"Gutmann","first_name":"Torsten"},{"full_name":"Buntkowsky, Gerd","last_name":"Buntkowsky","first_name":"Gerd"}],"status":"public","year":"2023","title":"Solute–Solvent Interactions of 2,2,6,6-Tetramethylpiperidinyloxyl and 5-Tert-Butylisophthalic Acid in Polyethylene Glycol as Observed by Measurements of Density, Viscosity, and Self-Diffusion Coefficient","volume":52,"user_id":"100715","doi":"10.1007/s10953-023-01265-4","language":[{"iso":"eng"}],"_id":"63984","page":"685–707","extern":"1","abstract":[{"text":"This study is seeking a better understanding of polyethylene glycol (PEG) as a solvent to promote its use in chemical synthesis. The effect of adding two solutes of interest, 2,2,6,6-tetramethylpiperidinyloxyl (TEMPO) and 5-tert-butylisophthalic acid (5-TBIPA) to PEG200 (average molar weight of 200 g·mol−1) on the solution density, viscosity, and self-diffusion coefficients is monitored in a temperature range of 298.15–358.15 K to deduce how these solutes interact with the PEG200 solvent. The effect of water, the most common impurity in PEGs, is also monitored and found to be nearly negligibly small. Addition of (5-TBIPA) increases solution density and viscosity. Combined with the observation that 5-TBIPA consistently self-diffuses at about half the rate as PEG200 at all investigated experimental conditions, this suggests strong attractive solute–solvent interactions likely through hydrogen bonding interactions. In contrast, addition of TEMPO causes lower solution densities and viscosities suggesting that the solute–solvent interactions of TEMPO lead to an overall weakening of the intermolecular interactions present compared to neat PEG200. Inspection of the viscosity and self-diffusion temperature dependence reveals slight deviations from the Arrhenius equation. Interestingly, the activation energies obtained from the viscosity and the self-diffusion data are essentially identical in values suggesting that the same dynamic processes and thus the same activation barriers govern translational motion and momentum transfer in these PEG200 solutions.","lang":"eng"}],"citation":{"bibtex":"@article{Hoffmann_Randall_Apak_Paddock_Gutmann_Buntkowsky_2023, title={Solute–Solvent Interactions of 2,2,6,6-Tetramethylpiperidinyloxyl and 5-Tert-Butylisophthalic Acid in Polyethylene Glycol as Observed by Measurements of Density, Viscosity, and Self-Diffusion Coefficient}, volume={52}, DOI={<a href=\"https://doi.org/10.1007/s10953-023-01265-4\">10.1007/s10953-023-01265-4</a>}, number={6}, journal={Journal of Solution Chemistry}, author={Hoffmann, Markus M. and Randall, Nathaniel P. and Apak, Miray H. and Paddock, Nathaniel A. and Gutmann, Torsten and Buntkowsky, Gerd}, year={2023}, pages={685–707} }","ama":"Hoffmann MM, Randall NP, Apak MH, Paddock NA, Gutmann T, Buntkowsky G.
