  text: 'Erklärungen spielen eine zentrale Rolle in alltäglichen persönlichen Gesprächen,
    indem sie den Wissensaustausch fördern, Ideen klären und das Verständnis unterstützen.
    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 &amp; 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 &amp; 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 &amp; Heller,
    2021), beispielsweise durch kontinuierliches Zeigen auf unsichtbare Orte, zeigte
    die Studie von Lazarov &amp; 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 &amp; Grimminger, 2024a) oder die
    verbalen Verständnissignale der Explainees wahrnahmen (Lazarov &amp; 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.'

  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 &amp; 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 &amp; 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 &amp; Heller, 2021), for example, by continuously
    pointing at invisible locations, the study by Lazarov &amp; 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 &amp; Grimminger, 2024a), or perceived
    the explainees'' verbal signals of understanding (Lazarov &amp; 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.'

  text: "Coherent Raman scattering techniques as coherent anti-Stokes Raman scattering
    (CARS), offer significant advantages in terms of pixel dwell times and speed as
    compared to spontaneous Raman scattering for investigations of crystalline materials.
    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 \U0001D70F=7.81 ps for the
    single \U0001D460⁢\U0001D45D3 peak."

  text: "<jats:title>ABSTRACT</jats:title>\r\n                  <jats:p>Effective
    manipulation of photonic spin–orbit coupling (SOC) in microcavities is of fundamental
    importance within topological photonics and applications. 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.</jats:p>"

  text: <jats:p>Frequency-filtered photon correlations have been proven to be extremely
    useful in grasping how the detection process alters photon statistics. 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.</jats:p>

  text: Doped Co3O4 nanoparticles are investigated via spectro-electrochemistry in
    the (pre-) oxygen evolution reaction (OER) regime by tracing the absorption signal
    of the Co3+ d–d transition under applied bias for getting insight into the catalysts
    activation and the formation of catalytically active phases. 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. We conclude that doping Co3O4 with transition
    metals affects the formation and potential-dependent thickness of the CoOx(OH)y
    skin layer as the catalytically active phase and the formation of long-time stable
    surface Co3+ states after activation in the first OER cycle.

  text: <jats:title>Abstract</jats:title><jats:p>The quartz crystal microbalance with
    dissipation monitoring (QCM‐D) is routinely used to investigate structured samples.
    Here, a simulation technique is described, that predicts the shifts of frequency
    and half bandwidth, Δ<jats:italic>f<jats:sub>n</jats:sub></jats:italic> and ΔΓ<jats:italic><jats:sub>n</jats:sub></jats:italic>,
    of a quartz resonator operating on different overtone orders, <jats:italic>n</jats:italic>,
    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 Δ<jats:italic>f<jats:sub>n</jats:sub></jats:italic>
    and ΔΓ<jats:italic><jats:sub>n</jats:sub></jats:italic> 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.
    FreqDLBM runs on an office PC and does not require expert knowledge of numerical
    techniques. It is accessible to an experimentalist.</jats:p>

  text: <jats:p>The solid electrolyte interphase (SEI) on the anode of lithium-ion
    batteries (LIBs) has been studied thoroughly due to its crucial importance to
    the battery’s long-term performance. 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.</jats:p>

  text: <jats:p>By monitoring the solidification of droplets of plant latices with
    a fast quartz crystal microbalance with dissipation monitoring (QCM-D), droplets
    from Campanula glomerata were found to solidify much faster than droplets from
    Euphorbia characias and also faster than droplets from all technical latices tested.
    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.</jats:p>

  text: 'Die DFG-Projekte AddFeRo-PM (406108415) und AddFeRo-SR (465089065) untersuchten
    die Potenziale des LB-PBF/M-Verfahrens zur Herstellung von Rotoren für unterschiedliche
    elektrische Maschinen. 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.'

  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.

    gold catalyzed acetylene hydrochlorination represents a classical landmark in
    eliminating global mercury pollution, but their sustainable implementation is
    hindered by acetylene‐dependence design criteria and high operating temperatures.
    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                    <jats:sup>δ⁻</jats:sup>\r\n
