  text: <jats:title>Abstract</jats:title><jats:p>The advantages of implementing demand
    side management (DSM) strategies in biogas production are explored. Specifically,
    the influence of agitation intervals on biogas production and the economic advantages
    of DSM in fermenter agitation are examined. The model‐based study highlights the
    detrimental effects of insufficient agitation, such as reduced active reaction
    volume and diminished biogas yield. The article further delves into the optimal
    agitation intervals corresponding to different electricity price levels and assesses
    the implications of DSM on biogas production. Results substantiate that such strategies,
    particularly at high and low electricity prices, can increase profit while reducing
    greenhouse gas emissions.</jats:p>

  text: Professionelle Entwicklung steht seit einigen Jahrzehnten im Fokus der Wissenschaft.
    Die Expertiseforschung geht der Frage nach, wie Personen das Vermögen erwerben,
    komplexe Situationen scheinbar mühelos zu bewältigen. Diese Arbeit reiht sich
    in diese Tradition ein und fokussiert mentale Simulation als besonderen Baustein
    zur Entwicklung von Intuition- eine zentrale Komponente von Expertise. Ergänzend
    wird ein Stufenmodell präsentiert, das die Qualität mentalen Simulierens als Entwicklungsprozess
    abbildet. Die empirische Untersuchung gedanklicher Auseinandersetzungen mit beruflich
    relevanten Herausforderungen erfolgt hierbei mittels eines Online-Fragebogens
    und durch Fall-Vignetten am Beispiel der Psychosozialen Notversorgung für Betroffene.
    Auf Basis der Ergebnisse werden Implikationen zukünftiger Intuitionsforschung
    aufgezeigt und anschließende Überlegungen zu unterschiedlichen Formen und Qualitäten
    mentaler Simulation angeregt.

  text: 'Füllstoffe erhöhen die Wärmeleitfähigkeit von im Fused Filament Fabrication
    (FFF) Verfahren hergestellten Strukturen. Neben der Füllstoffart ist dabei der
    Füllstoffvolumenanteil relevant. Der maximal verarbeitbare Füllstoffanteil ist
    hier gegenüber vergleichbaren Spritzgussmaterialien reduziert. An der Kunststofftechnik
    Paderborn (KTP) wurde untersucht, welchen Einfluss spezifische Füllstoffe auf
    die Materialeigenschaften haben. Die additive Fertigung (AM) gewinnt durch stetig
    steigende Anforderungen an die Bauteilkomplexität und Fertigungsflexibilität nicht
    nur im Prototypenbau an Bedeutung [1]. Eines der am weitesten verbreiteten additiven
    Fertigungsverfahren ist dabei das Fused Filament Fabrication (FFF) Verfahren [2].
    Bei diesem Verfahren wird ein Kunststofffilament in eine temperierte Düse gefördert,
    dort aufgeschmolzen und in einer charakteristischen, näherungsweise elliptischen
    Stranggeometrie ausgetragen. Durch die Verfahrbewegung der Plastifiziereinheit
    und der Bauplattform können dreidimensionale Strukturen gefertigt werden [3].
    Das FFF-Verfahren zeichnet sich unter anderem durch die Verarbeitung einer großen
    Bandbreite an thermoplastischen Kunststoffen aus [4]. Dies ermöglicht eine anwendungsspezifische
    Materialauswahl. In diesem Zusammenhang stellt auch die Modifizierung mit Füllstoffen
    eine Möglichkeit dar, die Materialeigenschaften gezielt einzustellen. Die Füllstoffe
    können dabei nach dem jeweiligen Aspektverhältnis in Kugeln, Plättchen oder Fasern
    unterteilt werden [5]. Die Steigerung der Wärmeleitfähigkeit von im FFF-Verfahren
    hergestellten Strukturen ist aktuell Stand der Forschung, gewinnt jedoch vor dem
    Hintergrund der aktuellen Herausforderungen, z. B. in der Elektrotechnik, an Bedeutung
    [6]. Die Kunststofftechnik Paderborn (KTP) befasst sich am Direct Manufacturing
    Research Center (DMRC) – Academic derzeit mit der Entwicklung und Verarbeitung
    wärmeleitfähiger Kunststoffe für das FFF-Verfahren. Der Fokus liegt dabei auf
    den material- und prozessseitigen Einflüssen auf die Materialeigenschaften. Für
    die Erzielung hoher Wärmeleitfähigkeiten sind dabei die Wahl der Füllstoffart
    und des Füllstoffvolumenanteils hervorzuheben. Kenntnisse über die Auswirkungen
    der Füllstoffzugabe und dem Zusammenspiel zwischen den mechanischen Eigenschaften
    und der Wärmeleitfähigkeit sind für die anwendungsgerechte Bauteilauslegung essenziell.
    Das Vorgehen Zur Analyse der Wärmeleitfähigkeit wurde eine am DMRC – Academic
    entwickelte Methode verwendet. Diese basiert auf der Fertigung von zylindrischen
    Probekörpern, welche im FFF-Verfahren entlang der Längsachse parallel zu den drei
    Koordinatenrichtungen X, Y und Z orientiert gefertigt werden. Im Anschluss werden
    die Probekörper spanend auf das für die Messung erforderliche Maß nachbearbeitet.
    Dadurch können fertigungsbedingte Einflüsse auf die Geometrie und Oberflächengüte
    reduziert und damit die Messgenauigkeit erhöht werden (Bild 2). Durch die Fertigung
    von drei unterschiedlichen Orientierungen kann weiterhin eine resultierende Anisotropie
    bewertet werden. Die auf einem Doppelschneckenextruder (Thermo Fisher Process11)
    hergestellten Filamente wurden nachfolgend mit einem Gewo HTP260 (Gewo Feinmechanik)
    verarbeitet. Die entsprechenden FFF-Prozessparameter sind in Tabelle 1 dargestellt.
    Dabei ist anzumerken, dass eine Bauraumtemperierung im Allgemeinen und der auf
    120 °C beheizte Bauraum für die Verarbeitung der betrachteten Materialien im Speziellen
    zur prozesssicheren FFF-Fertigung unerlässlich sind. Die Analyse der Wärmeleitfähigkeit
    erfolgte schließlich mittels der Laser-Flash-Analyse (LFA) (Netzsch LFA 467 HyperFlash)
    entsprechend der DIN EN ISO 22007-4 [7]. Für die Bewertung der mechanischen Eigenschaften
    wurden Probekörper entsprechend der DIN EN ISO 527-2 Typ 1BA unter Verwendung
    einer Kolben-Spritzgussmaschine (Thermo Fisher Mini Jet Pro) gefertigt und mit
    einer Zugprüfmaschine (Zwick/Roell ProLine Z 010) geprüft, um den grundlegenden
    Füllstoffeinfluss bewerten zu können [8]. Für die Untersuchungen wurde ein Kunststoff-Compound
    basierend auf Polybutylenterephthalat (PBT) ohne (PBTx) und mit (PBTxa) Verarbeitungshilfe
    verwendet. Als Füllstoffe kamen zwei wärmeleitfähige plättchenförmige Füllstoffe
    (Bezeichnung: F1 und F2) zur Anwendung, welche einen mittleren Partikeldurchmesser
    (d50) für F1 von 5,0 µm und für F2 von 7,9 µm aufweisen. Ergebnisse der Zugversuche
    Die Auswertung der mechanischen Eigenschaften zeigt den Einfluss des Füllstoffvolumenanteils
    anhand des Elastizitätsmoduls und der Bruchdehnung auf (Bild 3). Die resultierende
    Festigkeit wird durch die geringe Verstärkungswirkung der Plättchen hingegen nur
    geringfügig beeinflusst und ist folglich nicht gesondert aufgeführt. Im Gegensatz
    dazu erhöht sich die Steifigkeit mit steigendem Füllstoffvolumenanteil, was auf
    den erhöhten E-Modul der Füllstoffe gegenüber der Kunststoffmatrix zurückzuführen
    ist. So kann durch die Füllstoffzugabe mit einem Volumenanteil in Höhe von 22
    {%} der E-Modul für das Material PBTxa-F1 gegenüber der reinen Kunststoffmatrix
    um den Faktor 2,7 gesteigert werden. Hingegen nimmt die Bruchdehnung mit steigendem
    Füllstoffvolumenanteil ab. Diese mit dem Volumenanteil positiv korrelierende Versprödung
    stellt einen begrenzenden Faktor bei der Herstellung hochgefüllter Filamente dar.
    So neigen höher gefüllte Filamente eher zu einem Bruch bei der Herstellung und
    Verarbeitung. Dies resultiert in den vorliegenden maximalen Füllstoffvolumenanteilen,
    welche im Vergleich zu Spritzgussmaterialien deutlich reduziert sind. Eine weitere
    Erhöhung führt zu einer unzureichenden Prozessstabilität und damit zu einer unzureichenden
    Verarbeitungseignung für das FFF-Verfahren. Weiterhin zeigt sich, dass der Einfluss
    der verwendeten plättchenförmigen Füllstoffe für eine identische Kunststoffmatrix
    vergleichbar ist. Durch die Verwendung von Verarbeitungshilfen können die mechanischen
    Eigenschaften allerdings beeinflusst werden. Die Erhöhung des E-Moduls und der
    Bruchdehnung ist dabei auf die verbesserte Benetzung der Füllstoffpartikel und
    damit eine verbesserte Kunststoff-Füllstoff-Interaktion zurückzuführen. Bewertung
    der Wärmeleitfähigkeit Zur Darstellung der Ergebnisse der Wärmeleitfähigkeit wurden
    die Messergebnisse von je vier Probekörpern über die Prüftemperaturen zwischen
    30 °C und 180 °C in 30 °C Inkrementen gemittelt (Bild 4). Die Ergebnisse zeigen
    eine positive Korrelation zwischen einem zunehmenden Füllstoffvolumenanteil und
    der Wärmeleitfähigkeit. Diese Steigerung ist wiederum abhängig von der jeweilig
    verwendeten Füllstoffart. Hierbei liefert das Material PBTx-F2-X eine vergleichbare
    Wärmeleitfähigkeit wie die Materialien PBTx-F1 und PBTxa-F1 in der jeweiligen
    Y-Orientierung. Die Unterschiede zwischen den beiden Materialien PBTx-F1 und PBTxa-F1
    sind hingegen minimal und der Einfluss der Verarbeitungshilfe auf die Wärmeleitfähigkeit
    dementsprechend als vernachlässigbar anzusehen. Weiterhin ist eine anisotrope
    Wärmeleitfähigkeit für die mit Plättchen gefüllten Kunststoffe ersichtlich. Während
    die X-Orientierung (entlang der abgelegten Stränge) eine erhöhte Wärmeleitfähigkeit
    für alle Materialien liefert, ist diese für die Z-Orientierung (zwischen den Schichten)
    am geringsten. Gründe hierfür sind der Strangverbund sowie die Füllstofforientierung
    innerhalb der abgelegten Stränge. Dabei ist die aufgezeigte Anisotropie für den
    Füllstoff F2 im Vergleich zu F1 leicht reduziert und bestätigt den spezifischen
    Einfluss der Füllstoffart. Auf Basis der Ergebnisse können allgemein drei charakteristische
    Orientierungen zur Bewertung der Wärmeleitfähigkeit erfasst werden. Für die Bauteilauslegung
    ist der aufgezeigte Einfluss plättchenförmiger Füllstoffe auf die sich einstellende
    Anisotropie von im FFF-Verfahren gefertigten Strukturen zwingend zu beachten.
    Ausblick Die angeführten Untersuchungen zeigen, dass die Verwendung von plättchenförmigen
    Füllstoffen in Abhängigkeit von dem Füllstoffvolumenanteil zu einer Beeinflussung
    der Materialeigenschaften führt. Die dargelegten Ergebnisse stellen in diesem
    Kontext eine Grundlage zur Bewertung des Zusammenhangs zwischen den mechanischen
    Eigenschaften und der Wärmeleitfähigkeit dar. Insbesondere die Limitierung des
    Füllstoffvolumenanteils durch die erhöhte Versprödung ist hierbei anzuführen.
    Aktuelle Untersuchungen an der Kunststofftechnik Paderborn befassen sich mit der
    Betrachtung weiterer material- und prozessseitiger Einflussgrößen auf die Wärmeleitfähigkeit.
    Die generierten Daten sollen schließlich für die Entwicklung eines Modells zur
    Vorhersage der Wärmeleitfähigkeit von im FFF-Verfahren gefertigten Strukturen
    zusammengeführt werden.'

  text: Compounding is an important step in processing base polymers and is used to
    incorporate various additives into a polymer. For this purpose, different screw
    elements are used for dispersive and distributive mixing on a co-rotating twin-screw
    extruder. Optimising the screw configuration requires precise knowledge of the
    screw elements’ mixing properties, which have not been thoroughly investigated.
    This study analyses the mixing behaviour of individual screw elements regarding
    dispersive and distributive mixing using 3D CFD flow simulations with subsequent
    particle tracking. For distributive mixing, the particle distribution behind the
    screw elements in the XY plane is analysed and the mixing index MQ, which relates
    the standard deviation and the mean value of the triangular areas between the
    particles, is calculated. For dispersive mixing, the maximum shear stress on the
    particle path and the integral of the shear stress over the residence time of
    each individual particle are determined. The results show that screw element geometry
    and rotation speed have a significant influence on dispersive and distributive
    mixing. In addition, better dispersive mixing is achievable with highly viscous
    materials. These findings enable the optimisation of the mixing zone of a co-rotating
    twin-screw extruder for the efficient mixing of mineral fillers.

  text: Ferroelectric materials play a crucial role in a broad range of technologies
    due to their unique properties that are deeply connected to the pattern and behavior
    of their ferroelectric (FE) domains. Chief among them, barium titanate (BaTiO3;
    BTO) sees widespread applications such as in electronics but equally is a ferroelectric
    model system for fundamental research, e.g., to study the interplay of such FE
    domains, the domain walls (DWs), and their macroscopic properties, owed to BTO’s
    multiple and experimentally accessible phase transitions. Here, we employ Second
    Harmonic Generation Microscopy (SHGM) to in situ investigate the cubic-to-tetragonal
    (at ∼126°C) and the tetragonal-to-orthorhombic (at ∼5°C) phase transition in single-crystalline
    BTO via three-dimensional (3D) DW mapping. We demonstrate that SHGM imaging provides
    the direct visualization of FE domain switching as well as the domain dynamics
    in 3D, shedding light on the interplay of the domain structure and phase transition.
    These results allow us to extract the different transition temperatures locally,
    to unveil the hysteresis behavior, and to determine the type of phase transition
    at play (first/second order) from the recorded SHGM data. The capabilities of
    SHGM in uncovering these crucial phenomena can easily be applied to other ferroelectrics
    to provide new possibilities for in situ engineering of advanced ferroic devices.

  text: Ferroelectric domain walls (DWs) are promising structures for assembling future
    nano-electronic circuit elements on a larger scale since reporting domain wall
    currents of up to 1 mA per single DW. One key requirement hereto is their reproducible
    manufacturing by gaining preparative control over domain size and domain wall
    conductivity (DWC). To date, most works on DWC have focused on exploring the fundamental
    electrical properties of individual DWs within single-shot experiments, with an
    emphasis on quantifying the origins of DWC. Very few reports exist when it comes
    to comparing the DWC properties between two separate DWs, and literally nothing
    exists where issues of reproducibility in DWC devices have been addressed. To
    fill this gap while facing the challenge of finding guidelines for achieving predictable
    DWC performance, we report on a procedure that allows us to reproducibly prepare
    single hexagonal domains of a predefined diameter into uniaxial ferroelectric
    lithium niobate single crystals of 200 and 300 μm thickness, respectively. We
    show that the domain diameter can be controlled with an uncertainty of a few percent.
    As-grown DWs are then subjected to a standard procedure of current-limited high-voltage
    DWC enhancement, and they repetitively reach a DWC increase of six orders of magnitude.
    While all resulting DWs show significantly enhanced DWC values, their individual
    current–voltage (I–V) characteristics exhibit different shapes, which can be explained
    by variations in their 3D real structure reflecting local heterogeneities by defects,
    DW pinning, and surface-near DW inclination.

  text: Piezoresponse force microscopy (PFM) is one of the most widespread methods
    for investigating and visualizing ferroelectric domain structures down to the
    nanometer length scale. PFM makes use of the direct coupling of the piezoelectric
    response to the crystal lattice, and hence, it is most often applied to spatially
    map the three-dimensional (3D) near-surface domain distribution of any polar or
    ferroic sample. Nonetheless, since most samples investigated by PFM are at least
    semiconducting or fully insulating, the electric ac field emerging from the conductive
    scanning force microscopy (SFM) tip penetrates the sample and, hence, may also
    couple to polar features that are deeply buried into the bulk of the sample under
    investigation. Thus, in the work presented here, we experimentally and theoretically
    explore the contrast and depth resolution capabilities of PFM, by analyzing the
    dependence of several key parameters. These key parameters include the depth of
    the buried feature, i.e., here a domain wall (DW), as well as PFM-relevant technical
    parameters such as the tip radius, the PFM drive voltage and frequency, and the
    signal-to-noise ratio. The theoretical predictions are experimentally verified
    using x-cut periodically poled lithium niobate single crystals that are specially
    prepared into wedge-shaped samples, in order to allow the buried feature, here
    the DW, to be “positioned” at any depth into the bulk. This inspection essentially
    contributes to the fundamental understanding in PFM contrast analysis and to the
    reconstruction of 3D domain structures down to a 1 μm-penetration depth into the
    sample.

  text: <jats:p>A method for the construction of bijective volumetric maps between
    3D shapes is presented. Arbitrary shapes of ball-topology are supported, overcoming
    restrictions of previous methods to convex or star-shaped targets. In essence,
    the mapping problem is decomposed into a set of simpler mapping problems, each
    of which can be solved with previous methods for discrete star-shaped mapping
    problems. Addressing the key challenges in this endeavor, algorithms are described
    to reliably construct structurally compatible partitions of two shapes with constraints
    regarding star-shapedness and to compute a parsimonious common refinement of two
    triangulations.</jats:p>

  text: Promising cathode materials for fluoride-ion batteries (FIBs) are 3d transition
    metal containing oxides with Ruddlesden-Popper-type structure. So far, multi-elemental
    compositions were not investigated, but could alternate electrochemical performance
    similar to what has been found for cathode materials for lithium-ion batteries.
    Within this study, we investigate RP type La2Ni0.75Co0.25O4.08 as an intercalation-based
    active cathode material for all-solid-state FIBs. We determine the structural
    changes of La2Ni0.75Co0.25O4.08 during fluoride intercalation / de-intercalation
    by ex-situ X-ray diffraction, which showed that F- insertion leads to transformation
    of the parent phase to three different phases. Changes in Ni and Co oxidation
    states and coordination environment were examined by X-ray absorption spectroscopy
    and magnetic measurements in order to understand the complex reaction behaviour
    of the phases in detail, showing that the two transition metals behave differently
    in the charging and discharging process. Under optimized operating conditions,
    a cycle life of 120 cycles at a critical cut-off capacity of 40 mAh g-1 against
    Pb/PbF2 was obtained, which is one of the highest observed for intercalation electrode
    materials in FIBs so far. The average Coulombic efficiencies ranged from 85% to
    90%. Thus, La2Ni0.75Co0.25O4.08 could be a promising candidate for cycling-stable
    high-energy cathode materials for all-solid-state FIBs
