In solchen Gesprächen versuchen die Erklärenden (d. h. die sachkundigere Person), das Verständnis der Explainees (d. h. die Person, die eine Erklärung erhält) durch Interaktionsprozesse wie Monitoring, Scaffolding und gemeinsame Konstruktion zu verbessern (Buschmeier et al., 2023; Rohlfing et al., 2021). Während gemeinsame Konstruktionen aus dem bidirektionalen (non-)verbalen Austausch zwischen den Gesprächspartnern entstehen, bezeichnet Scaffolding den Prozess, durch den die Erklärenden eine Erklärung anpassen, indem sie unterschiedliche Verhaltensweisen als Reaktion auf das Verhalten der Explainees einsetzen, welches deren kognitive Verarbeitung signalisiert (Wood et al., 1976). Monitoring bezeichnet einen kontinuierlichen Prozess, in dem die Gesprächspartner auf Wahrnehmungssignale wie (non-)verbale Verhaltensweisen achten, um Hinweise auf (Miss-)Verständnisse zu erkennen und zu interpretieren (Clark & Krych, 2004).In der vorliegenden Arbeit berichte ich über fünf Studien zu dyadischen Erklärungen zwischen Menschen und diskutiere anhand empirischer Befunde die Interaktionsdynamiken, die bestimmten Formen verbalen und nonverbalen Erklärungsverhaltens zugrunde liegen. Zu diesem Zweck analysierte ich in den vorgestellten Studien Daten aus zwei Videokorpora zu verschiedenen Bereichen alltäglicher Erklärungen, beispielsweise medizinischen Erklärungen und Brettspielerklärungen. Das Korpus zu medizinischen Erklärungen umfasst elf naturalistische Interaktionen zwischen Ärzten und Bezugspersonen über eine bevorstehende chirurgische Operation von Kindern. Das Korpus zu Brettspielerklärungen besteht aus 87 dyadischen Brettspielerklärungen, von denen eine Teilstichprobe von 24 Interaktionen in den vorgestellten Studien spezifisch untersucht wurde.Um das verbale Erklärungsverhalten zu untersuchen, analysierte ich in zwei Studien, die sich mit medizinischen Erklärungen und Brettspielerklärungen befassten, den Zusammenhang zwischen Themenwechseln in Erklärungen und dem multimodalen Verhalten der Explainees, das von den Erklärenden beobachtet wurde. Die Analyse medizinischer Erklärungen legt nahe, dass der Wechsel von Elaborationen zu neuen Themen mit dem multimodalen Verhalten der Explainees einhergeht, welches Blickabwendung, Kopfnicken und verbale Rückkopplung umfasst. Der Wechsel zu Elaborationen hingegen ist mit einer anhaltenden Blickrichtung verbunden, unabhängig davon, ob zusätzliche Signale vorhanden sind oder nicht (Lazarov et al., 2024). Eine nachfolgende Studie zu Brettspielerklärungen (Lazarov & Grimminger, in Begutachtung) erweiterte diese Analyse durch die Einbeziehung des Blickverhaltens der Erklärenden. Die Studie untersuchte den Zusammenhang zwischen gegenseitigem Blickkontakt und Blickabwendung mit der Einleitung neuer Themen. Die Ergebnisse bestätigten die Ergebnisse aus dem medizinischen Kontext: Blickabwendungen der Explainees gehen Themenwechseln häufiger voraus als gegenseitiger Blickkontakt, was mit früheren Forschungsergebnissen von Rossano (2012, 2013) übereinstimmt. Die Analyse untersuchte zudem den Zusammenhang zwischen dem / der Gesprächspartner:in, der / die Blickabwendungen initiierte, und dem / der Gesprächspartner:in, der / die Themenwechsel initiierte.Um das nonverbale Erklärungsverhalten zu untersuchen, analysierte ich die Verwendung von sprachbegleitenden Gesten von verschiedenen Erklärenden in drei Studien zu Brettspielerklärungen, in denen das zu erklärende Objekt im gemeinsamen Referenzraum physisch nicht vorhanden war. Obwohl diese Abwesenheit ein fortwährendes Bedürfnis nach der Etablierung gemeinsamer imaginärer Räume impliziert (Kang et al., 2015; Kinalzik & Heller, 2021), beispielsweise durch kontinuierliches Zeigen auf unsichtbare Orte, zeigte die Studie von Lazarov & Grimminger (2025), dass Gestenikonizität und zeitliche Hervorhebung auch in Themen zu Objekteigenschaften, Handlungsprozessen und bedingten Regeln variabel auftreten.Motiviert durch die kontinuierliche Verwendung von der gestischen Deixis während der physischen Abwesenheit des Explanandums erforschten die letzten zwei Studien den kognitiven Mechanismus der Anpassung des Gebrauchs deiktischer Gesten in Bezug auf die Beobachtung des Verständnisses der Explainees. Unabhängig davon, ob die Erklärenden das Verständnis der Explainees in einer retrospektiven Video Recall Aufgabe interpretierten (Lazarov & Grimminger, 2024a) oder die verbalen Verständnissignale der Explainees wahrnahmen (Lazarov & Grimminger, 2024b), zeigten die Analysen, dass die Häufigkeit der gestischen Deixis während der Erklärungsphase, in der das Explanandum nicht im gemeinsamen Raum vorhanden war, stabil blieb. Zu den Ergebnissen der in dieser Dissertation präsentierten Studien diskutiere ich, wie die kontinuierliche Beobachtung des Feedbackverhaltens der Explainees Anpassungen sowohl im verbalen als auch im nonverbalen Erklärungsverhalten erläutern kann. Darüber hinaus verdeutlichen die von mir präsentierten Studien das Ausmaß der individuellen Variation innerhalb und zwischen den Erklärenden, von denen jeder / jede mit drei verschiedenen Explainees interagierte.","lang":"eng"},{"lang":"eng","text":"Explanations play a central role in everyday face-to-face interactions by helping people share knowledge, clarify ideas, and support understanding. In face-to-face explanations, explainers (i.e., the more knowledgeable part) seek to enhance explainees’ understanding of an explanandum through interactional processes such as monitoring, scaffolding, and co-constructions (Buschmeier et al., 2023; Rohlfing et al., 2021). While co-constructions emerge from the bidirectional (non-)verbal exchange between the interlocutors, scaffolding refers to the process by which the explainers tailor an explanation by employing different forms of behavior in response to the explainees' behavior signaling their cognitive processing (Wood et al., 1976). Monitoring denotes a continuous process in which the interlocutors attend to perceptual evidence, such as (non-)verbal behaviors, to identify and interpret cues of (mis)understanding (Clark & Krych, 2004).In the present thesis, I report five studies on dyadic human–human explanations, and based on empirical findings, I discuss the interactional dynamics underpinning some forms of the verbal and nonverbal explaining behavior. To this end, in the reported studies, I analyzed data from two video corpora on different domains of everyday explanations, such as medical and board game explanations. The corpus on medical explanations comprises eleven naturalistic interactions between physicians and caregivers about an upcoming pediatric surgery. The corpus on board game explanations consists of 87 dyadic board game explanations, from which a subsample of 24 interactions was specifically addressed in the reported studies.To explore the verbal explaining behavior, I examined the relation between topical shifts in explanations and the explainees’ multimodal behavior as monitored by the explainers in two studies addressing the domains of medical and board game explanations. The analysis of medical explanations suggests that shifts from elaborations to new topics are associated with the explainees' multimodal behavior that comprises gaze aversions, co-occurring with head nodding, and vocal backchanneling, whereas shifts into elaborations are associated with a sustained gaze direction, whether accompanied by additional cues or not (Lazarov et al., 2024). A subsequent study on board game explanations (Lazarov & Grimminger, under review) extended this analysis by incorporating the explainers’ gaze behavior. The study investigated the relation of mutual gaze and gaze withdrawals to the initiation of new topics. The findings corroborated those from the medical context: the explainees' gaze withdrawals precede topical changes more frequently than mutual gaze, which corresponds to prior research by (Rossano, 2012, 2013). The analysis further investigated the relation between the initiator of gaze withdrawals and the initiator of topical changes.To examine the nonverbal explaining behavior, I analyzed the use of co-speech gestures by different explainers in three studies on board game explanations, during which the explanandum was physically absent from the shared space. Although this absence implies a persistent need for establishing joint imagined spaces (Kang et al., 2015; Kinalzik & Heller, 2021), for example, by continuously pointing at invisible locations, the study by Lazarov & Grimminger (2025) revealed that gesture iconicity and temporal highlighting also occur variably across explanation topics about object features, action processes, and conditional rules.Motivated by the continuous use of gesture deixis during the physical absence of the explanandum, the last two studies explored the cognitive mechanism of adapting the use of deictic gestures in relation to the monitoring of the explainees' understanding. Whether the explainers interpreted the explainees' understanding in a retrospective video recall task (Lazarov & Grimminger, 2024a), or perceived the explainees' verbal signals of understanding (Lazarov & Grimminger, 2024b), the analyses demonstrated that the frequency of gesture deixis remains stable over the course of the explanation phase in which the explanandum was absent from the shared space.Building on the results from the studies presented in this thesis, I discuss how the continuous monitoring of the explainees' feedback behavior accounts for adaptations in both the verbal and the nonverbal modes of explaining behavior. Furthermore, the analyses I present illuminate the extent of individual variation within and across explainers, each of whom interacted with three different explainees."}],"project":[{"_id":"112","name":"TRR 318; TP A02: Verstehensprozess einer Erklärung beobachten und auswerten"}],"page":"167","_id":"62748","language":[{"iso":"eng"}],"publisher":"Universitätsbibliothek Paderborn","user_id":"90345","doi":"10.17619/UNIPB/1-2446","year":"2025","status":"public","title":"The reflection of interactional monitoring in the dynamics of verbal and nonverbal forms of explaining","author":[{"id":"90345","orcid":"0009-0009-0892-9483","first_name":"Stefan Teodorov","last_name":"Lazarov","full_name":"Lazarov, Stefan Teodorov"}],"publication_status":"published","date_updated":"2025-12-02T14:21:41Z"},{"citation":{"ieee":"F.

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."}],"date_created":"2025-12-02T19:21:33Z","department":[{"_id":"15"},{"_id":"623"},{"_id":"288"}],"type":"journal_article","publication_identifier":{"issn":["2469-9950","2469-9969"]},"author":[{"full_name":"Hempel, F.","last_name":"Hempel","first_name":"F."},{"id":"22501","orcid":"0000-0003-4682-4577","last_name":"Rüsing","first_name":"Michael","full_name":"Rüsing, Michael"},{"first_name":"F.","last_name":"Vernuccio","full_name":"Vernuccio, F."},{"last_name":"Spychala","first_name":"K.

Anisotropic organic single‐crystalline materials can induce abundant SOC phenomenon due to their flexible tunability of molecular geometries, however, the intrinsic relationship between molecular geometries/orientations in 3D space and photonic SOC is lacking. In this study, we design two kinds of 2D organic polymorphs for the construction of organic microcavities to investigate the structure‐performance relationships. In two polymorphic microcavities, two distinctive photonic SOC phenomena are observed regardless of the in‐plane anisotropy of organic polymorphs. Theoretical analysis indicates that the photonic SOC strength is strongly influenced by the synergies between the crystal anisotropy and the tilted collective molecular transition dipole moment. Our results uncover the correlation mechanism between the structure of molecules and photonic SOC and open an avenue to engineer complex photonic SOC by use of organic microstructures towards the development of diverse integrated photonic devices.","lang":"eng"}],"date_created":"2025-12-04T12:33:48Z","type":"journal_article","department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"705"},{"_id":"35"},{"_id":"230"}]},{"user_id":"79748","language":[{"iso":"eng"}],"_id":"62882","date_updated":"2025-12-04T14:13:30Z","author":[{"id":"79748","full_name":"Osnabrügge, Malin","last_name":"Osnabrügge","first_name":"Malin"},{"id":"67302","full_name":"Tenberge, Claudia","last_name":"Tenberge","first_name":"Claudia"}],"conference":{"location":"Postdam ","start_date":"2025-09-29","name":"Digitale Transformation für Schule und Lehrkräftebildung ","end_date":"2025-09-30"},"status":"public","year":"2025","title":"Digital-gestützt lehren lernen: Technikbezogenen Unterricht zukunftsfähig gestalten","type":"conference","date_created":"2025-12-04T13:58:04Z","citation":{"ama":"Osnabrügge M, Tenberge C.

Harnessing the spectral correlations also permits refinement of the emission and unraveling of previously hidden strong correlations in a plethora of quantum-optical systems under continuous-wave excitation. In this work, we investigate such correlations for time-dependent excitation and develop a methodology to compute efficiently time-integrated correlations, which are at the heart of the photon-counting theory, and subsequently apply it to analyze the photon emission of pulsed systems. By combining this formalism with the —which facilitates frequency-resolved correlations—we demonstrate how spectral filtering enhances single-photon purity and suppresses multiphoton noise in time-bin-encoded quantum states. Specifically, filtering the central spectral peak of a dynamically driven two-level system boosts temporal coherence and improves the fidelity of time-bin entanglement preparation, even under conditions favoring multiphoton emission. These results establish spectral filtering as a critical tool for tailoring photon statistics in pulsed quantum light sources.","lang":"eng"}],"issue":"3","publication":"Physical Review Research","type":"journal_article","date_created":"2025-12-05T08:47:30Z","date_updated":"2025-12-05T08:48:02Z","publication_status":"published","intvolume":" 7","title":"Spectral correlations of dynamical resonance fluorescence","year":"2025","publication_identifier":{"issn":["2643-1564"]},"author":[{"last_name":"Bermúdez-Feijóo","first_name":"Santiago","full_name":"Bermúdez-Feijóo, Santiago"},{"full_name":"Zubizarreta Casalengua, Eduardo","first_name":"Eduardo","last_name":"Zubizarreta Casalengua"},{"first_name":"Kai","last_name":"Müller","full_name":"Müller, Kai"},{"full_name":"Jöns, Klaus D.","first_name":"Klaus D.","last_name":"Jöns"}],"doi":"10.1103/jmy9-bd3l","article_number":"033296","language":[{"iso":"eng"}]},{"status":"public","publisher":"American Chemical Society (ACS)","_id":"61982","page":"18391-18403","volume":15,"user_id":"116779","citation":{"mla":"Kampermann, L., et al. “Operando Analysis of the Pre-OER Activation of Metal-Doped Co3O4 Nanoparticle Catalysts.” ACS Catalysis, vol. 15, no. 21, American Chemical Society (ACS), 2025, pp. 18391–403, doi:10.1021/acscatal.5c03900.","bibtex":"@article{Kampermann_Klein_Wagner_Kotova_Placke-Yan_Yasar_Jacobse_Lasagna_Leppin_Schulz_et al._2025, title={Operando Analysis of the Pre-OER Activation of Metal-Doped Co3O4 Nanoparticle Catalysts}, volume={15}, DOI={10.1021/acscatal.5c03900}, number={21}, journal={ACS Catalysis}, publisher={American Chemical Society (ACS)}, author={Kampermann, L. and Klein, J. and Wagner, T. and Kotova, A. and Placke-Yan, C. and Yasar, A. and Jacobse, L. and Lasagna, S. and Leppin, Christian and Schulz, S. and et al.}, year={2025}, pages={18391–18403} }","ama":"Kampermann L, Klein J, Wagner T, et al.

In the low potential regime up to 1.37 VRHE, a rise in the optical absorption signal of the [Co3+]oct d–d transition is observed and attributed to a structural change from [Co2+]tet to [Co3+]oct due to an electrochemically induced surface restructuring with water. For applied potentials higher than 1.37 VRHE an overall offset of the absorption spectra in the UV–vis range, equivalent to a darkening of the materials is detected. This is attributed to the formation of a CoOx(OH)y skin layer as supported by high-energy X-ray diffraction (HE-XRD) measurements. We found that the kinetics of the Co3+ states are heavily influenced by the type of dopant with V-doped Co3O4 exhibiting stable Co3+ states (>20 min) while the Mn-doped Co3O4 Co3+ states reduce within 36 s under reductive bias.

Here, a simulation technique is described, that predicts the shifts of frequency and half bandwidth, Δfn and ΔΓn, of a quartz resonator operating on different overtone orders, n, induced by structured samples in contact with the resonator surface in liquid. The technique, abbreviated as FreqD‐LBM, solves the Stokes equation in the frequency domain. The solution provides the complex amplitude of the area‐averaged tangential stress at the resonator surface, from which Δfn and ΔΓn are derived. Because the dynamical variables are complex amplitudes, the viscosity can be complex, as well. The technique naturally covers viscoelasticity. Limitations are linked to the grid resolution and to problems at large viscosity. Validation steps include viscoelastic films, rough surfaces, an oscillating cylinder in a viscous medium, and a free‐floating sphere above the resonator. Application examples are soft adsorbed particles, stiff adsorbed particles, and a large, immobile spherical cap above the resonator, which allows to study the high‐frequency properties of the material in the gap.

At the same time, most studies of the SEI apply ex situ characterization methods, which may introduce artifacts or misinterpretations as they do not investigate the SEI in its unaltered state immersed in liquid battery electrolyte. Thus, in this work, we focus on using the non-destructive combination of electrochemical quartz crystal microbalance with dissipation monitoring (EQCM-D) and impedance spectroscopy (EIS) in the same electrochemical cell. EQCM-D can not only probe the solidified products of the SEI but also allows for the monitoring of viscoelastic layers and viscosity changes of the electrolyte at the interphase during the SEI formation. EIS complements those results by providing electrochemical properties of the formed interphase. Our results highlight substantial differences in the physical and electrochemical properties between the SEI formed on copper and on amorphous carbon and show how formation parameters and the additive vinylene carbonate (VC) influence their growth. The EQCM-D results show consistently that much thicker SEIs are formed on carbon substrates in comparison to copper substrates.","lang":"eng"}],"extern":"1","issue":"7","publication":"Batteries","doi":"10.3390/batteries11070273","article_number":"273","language":[{"iso":"eng"}],"date_updated":"2025-12-18T17:47:08Z","publication_status":"published","intvolume":" 11","article_type":"original","title":"Comparing the SEI Formation on Copper and Amorphous Carbon: A Study with Combined Operando Methods","year":"2025","publication_identifier":{"issn":["2313-0105"]},"author":[{"full_name":"Stich, Michael","first_name":"Michael","last_name":"Stich"},{"full_name":"Leppin, Christian","last_name":"Leppin","first_name":"Christian","id":"117722"},{"full_name":"Krauss, Falk Thorsten","last_name":"Krauss","first_name":"Falk Thorsten"},{"first_name":"Jesus Eduardo","last_name":"Valdes Landa","full_name":"Valdes Landa, Jesus Eduardo"},{"full_name":"Pantenburg, Isabel","first_name":"Isabel","last_name":"Pantenburg"},{"first_name":"Bernhard","last_name":"Roling","full_name":"Roling, Bernhard"},{"first_name":"Andreas","last_name":"Bund","full_name":"Bund, Andreas"}]},{"volume":14,"user_id":"117722","publisher":"MDPI AG","_id":"63224","status":"public","citation":{"bibtex":"@article{Langhoff_Peschel_Leppin_Kruppert_Speck_Johannsmann_2025, title={Rapid Solidification of Plant Latices from Campanula glomerata Driven by a Sudden Decrease in Hydrostatic Pressure}, volume={14}, DOI={10.3390/plants14050798}, number={5798}, journal={Plants}, publisher={MDPI AG}, author={Langhoff, Arne and Peschel, Astrid and Leppin, Christian and Kruppert, Sebastian and Speck, Thomas and Johannsmann, Diethelm}, year={2025} }","ama":"Langhoff A, Peschel A, Leppin C, Kruppert S, Speck T, Johannsmann D.

A similar conclusion was drawn from optical videos, where the plants were injured and the milky fluid was stretched (sometimes forming fibers) after the cut. Rapid solidification cannot be explained with physical drying because physical drying is transport-limited and therefore is inherently slow. It can, however, be explained with coagulation being triggered by a sudden decrease in hydrostatic pressure. A mechanism based on a pressure drop is corroborated by optical videos of both plants being injured under water. While the liquid exuded by E. characias keeps streaming away, the liquid exuded by C. glomerata quickly forms a plug even under water. Presumably, the pressure drop causes an influx of serum into the laticifers. The serum, in turn, triggers a transition from a liquid–liquid phase separated state (an LLPS state) of a resin and hardener to a single-phase state. QCM measurements, optical videos, and cryo-SEM images suggest that LLPS plays a role in the solidification of C. glomerata."}],"extern":"1","publication":"Plants","issue":"5"},{"citation":{"bibtex":"@article{Leppin_Langhoff_Johannsmann_2025, title={A fast electrochemical quartz crystal microbalance (EQCM) evidences the presence of nanobubbles in alkaline water splitting}, volume={27}, DOI={10.1039/d5cp02691a}, number={37}, journal={Physical Chemistry Chemical Physics}, publisher={Royal Society of Chemistry (RSC)}, author={Leppin, Christian and Langhoff, Arne and Johannsmann, Diethelm}, year={2025}, pages={19733–19747} }","ama":"Leppin C, Langhoff A, Johannsmann D.

Im interdisziplinären Ansatz wurden Materialentwicklung und mechanische sowie elektromagnetische Optimierung verbunden. Im Projekt „AddFeRo-PM“ wurde der Rotor einer permanentmagneterregten Synchron- maschine (PMSM) untersucht. FeSi erwies sich als geeignete Legierung, konnte aber wegen Spannungsrissen nur bis zu 3 % Siliziumanteil (kurz: FeSi3) verarbeitet werden. Mechanische und elektromagnetische Untersuchungen ermöglichten eine 3D-Optimierung der Rotorgeometrie und -struktur. Der Demonstrator wurde additiv gefertigt und zeigt Leicht-baupotenziale sowie reduzierte Drehmomentwelligkeit. Im Folgeprojekt „AddFeRo-SR“ kam eine Hochtemperatur-Bauraumheizung (HTBH) zum Einsatz, die FeSi mit 6,5 % Siliziumanteil verarbeitbar machte, welches bessere elektro- magnetische Eigenschaften bietet. Sie wurde bei einer Synchron-Reluktanzmaschine (SynRM) getestet. Eine hybride Rotorfertigung erwies sich jedoch aufgrund von HTBH-Einschränkungen als ungeeignet, weshalb eine einteilige Fertigung mit FeSi3 umgesetzt wurde. Experimente bestätigten vergleichbare Betriebsergebnisse zur konventionellen Fertigung bei reduzierter Rotormasse. Zusätzlich wurde eine Methodik entwickelt, um additive Verfahren als Ergänzung zur konventionellen Fertigung zu integrieren. Beide Projekte zeigen das Potenzial additiver Fertigung für Leichtbau und Wirkungsgradsteigerung im Elektromaschinenbau und bieten wertvolle Grundlagen für industrielle Anwendungen.","lang":"ger"}]},{"abstract":[{"text":"Periodically poled thin-film lithium niobate (TFLN) crystals are the fundamental building block for highly-efficient quantum light sources and frequency converters. The efficiency of these devices is strongly dependent on the interaction length between the light and the nonlinear material, scaling quadratically with this parameter. Nevertheless, the fabrication of long, continuously poled areas in TFLN remains challenging, the length of continuously poled areas rarely exceeds 10 mm. In this work, we demonstrate a significant progress in this field achieving the periodic poling of continuous poled areas of 70 mm length with a 3 μm poling period and a close to 50 % duty cycle. We compare two poling electrode design approaches to fabricate long, continuous poled areas. The first approach involves the poling of a single, continuous 70 mm long electrode. The second utilize a segmented approach including the poling of more than 20 individual sections forming together a 70 mm long poling area with no stitching errors. While the continuous electrode allows for faster fabrication, the segmented approach allows to individually optimize the poling resulting in less duty cycle variation. A detailed analysis of the periodic poling results reveals that the results of both are consistent with previously reported poling outcomes for shorter devices. Thus, we demonstrate wafer-scale periodic poling exceeding chiplet-size without any loss in the periodic poling quality. Our work presents a key step towards highly-efficient, narrow-bandwidth and low-pump power nonlinear optical devices.","lang":"eng"}],"publication":"Nanophotonics","department":[{"_id":"15"},{"_id":"288"},{"_id":"623"}],"type":"journal_article","date_created":"2025-12-01T08:45:07Z","intvolume":" 14","article_type":"original","date_updated":"2026-01-07T12:06:29Z","publication_status":"published","publication_identifier":{"issn":["2192-8606","2192-8614"]},"author":[{"full_name":"Bollmers, Laura","first_name":"Laura","last_name":"Bollmers","id":"61375"},{"last_name":"Spiegelberg","first_name":"Noah","full_name":"Spiegelberg, Noah"},{"id":"22501","first_name":"Michael","orcid":"0000-0003-4682-4577","last_name":"Rüsing","full_name":"Rüsing, Michael"},{"first_name":"Christof","orcid":"https://orcid.org/0000-0002-5693-3083","last_name":"Eigner","full_name":"Eigner, Christof","id":"13244"},{"full_name":"Padberg, Laura","first_name":"Laura","last_name":"Padberg","id":"40300"},{"first_name":"Christine","last_name":"Silberhorn","full_name":"Silberhorn, Christine","id":"26263"}],"title":"Segmented finger electrodes to optimize ultra-long continuous wafer-scale periodic poling in thin-film lithium niobate","year":"2025","doi":"10.1515/nanoph-2025-0461","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://doi.org/10.1515/nanoph-2025-0461","open_access":"1"}],"quality_controlled":"1","citation":{"bibtex":"@article{Bollmers_Spiegelberg_Rüsing_Eigner_Padberg_Silberhorn_2025, title={Segmented finger electrodes to optimize ultra-long continuous wafer-scale periodic poling in thin-film lithium niobate}, volume={14}, DOI={10.1515/nanoph-2025-0461}, journal={Nanophotonics}, publisher={Walter de Gruyter GmbH}, author={Bollmers, Laura and Spiegelberg, Noah and Rüsing, Michael and Eigner, Christof and Padberg, Laura and Silberhorn, Christine}, year={2025}, pages={4761} }","ama":"Bollmers L, Spiegelberg N, Rüsing M, Eigner C, Padberg L, Silberhorn C.

Herein, a platform of carbon‐supported single‐atoms Au catalysts (Au/BC and Au/NC) with polarized charge characteristics are developed via engineering Au sites with hosted B, N configurations. The negatively charged Au/BC catalyst unlocks the low‐temperature inactivity (413–423K) of the Au/NC catalyst while exhibiting superior catalytic performance in the 433–473K operating temperature range. We confirm that the classical scaling relationships on acetylene can be broken by narrowing the adsorption capacity between acetylene and HCl on Au\r\n δ⁻\r\n sites via facilitating the back‐donation of\r\n d\r\n electrons into the antibonding orbitals of acetylene. Prolonging the durability of Au catalysts is achieved through preceding an additional robust Au\r\n δ⁻\r\n → Au\r\n δ⁺\r\n cycle prior to the classic Au\r\n δ⁺\r\n → Au\r\n 0\r\n route.
