The float current, IFloat , represents the recharge current required to maintain the cell at a fixed potential during calendar aging. This current arises as lithium is irreversibly consumed at the anode or inserted into the cathode, shifting the electrode potentials. To account for the asymmetric response of the electrodes, a voltage-dependent scaling factor, SF, is introduced, derived from the slopes of the electrode-specific voltage curves. Using this factor in combination with measured float currents and capacity loss rates from check-up tests, ISEIgrowth and ICL is quantified at 30 °C across various float voltages. Although the SF and capacity data are limited to 30 °C, the model is extended to a range of 5-50 °C using only float current measurements. The results show that using capacity loss rates alone underestimate ISEIgrowth and that ICL, contributes significantly to the observed float current at elevated voltages, indicating that cathode lithiation plays an increasingly important role in high-voltage calendar aging.}, language = {en} } @article{VolpatodeSouzaPintoPereiraNeumeieretal.2025, author = {Volpato, Guilherme and de Souza Pinto Pereira, Adriano and Neumeier, Steffen and Hotza, Dachamir and G{\"o}ken, Mathias and Tetzlaff, Ulrich and Fredel, M{\´a}rcio Celso}, title = {Influence of a Standard Heat Treatment on the Microstructure and Properties of Inconel X-750 Produced by Laser Powder Bed Fusion}, volume = {27}, pages = {2500306}, journal = {Advanced Engineering Materials}, number = {24}, publisher = {Wiley}, address = {Weinheim}, issn = {1527-2648}, doi = {https://doi.org/10.1002/adem.202500306}, year = {2025}, abstract = {The production of nickel-base superalloys through powder bed fusion using a laser beam (PBF-LB) offers a promising method for reducing the cost of aeronautical components, especially those with complex geometries. However, when these materials are processed using PBF-LB, the standard heat treatments developed for conventional manufacturing routes do not consistently yield predictable microstructures or mechanical properties. Thus, this study analyzes how PBF-LB affects the microstructure and mechanical behavior of Inconel alloy X-750 when compared to a hot-rolled counterpart after undergoing a standard precipitation-hardening heat treatment (solution annealing, stabilization, and precipitation). Microstructure is examined using analytical electron microscopy and high-energy X-ray diffraction, while mechanical behavior is assessed through microhardness. Significant differences between both manufacturing routes are detected, so that PBF-LB processing led to an increase in grain size, anisotropy, fraction of low-angle grain boundaries, mean angle of misorientation, and dislocation density. Moreover, PBF-LB promoted the formation of γ′-Ni3(Al,Ti) and η-Ni3Ti phases during solution annealing and stabilization, respectively. Notably, the formation of γ′ contributes to an anomalous microhardness increase observed between these steps. These findings suggest that PBF-LB may inhibit recrystallization and facilitate precipitation during heat treatment, thereby affecting the performance of components produced using this technology.}, language = {en} } @inbook{BauerGleissnerKotonski2025, author = {Bauer, Ingrid and Gleissner, Christian and Kotonski, Julia}, title = {On Rigid Manifolds of Kodaira Dimension 1}, booktitle = {Perspectives on Four Decades of Algebraic Geometry, Volume 1: In Memory of Alberto Collino}, editor = {Albano, Alberto and Aluffi, Paolo and Bolognesi, Michele and Casagrande, Cinzia and Colombo, Elisabetta and Conte, Alberto and Grassi, Antonella and Pedrini, Claudio and Pirola, Gian Pietro and Verra, Alessandro}, publisher = {Birkh{\"a}user}, address = {Cham}, isbn = {978-3-031-66229-4}, doi = {https://doi.org/10.1007/978-3-031-66230-0_2}, pages = {43 -- 71}, year = {2025}, language = {en} } @inbook{LozaAdaui2025, author = {Loza Adaui, Cristian Rolando}, title = {The Principle of Respect in Circular Economy: Recognising Worth and Boundaries}, booktitle = {Circular Economy in Sustainable Supply Chains: A Global Perspective on Challenges, Concepts and Cases}, editor = {Fr{\"o}hlich, Elisabeth and Steinbiß, Kristina Kristina and Schmiedeknecht, Maud Helene and Loza Adaui, Cristian Rolando}, publisher = {Springer}, address = {Cham}, isbn = {978-3-031-70749-0}, doi = {https://doi.org/10.1007/978-3-031-70749-0_2}, pages = {21 -- 33}, year = {2025}, language = {en} } @inbook{LozaAdaui2025, author = {Loza Adaui, Cristian Rolando}, title = {The Principle of Responsibility in Circular Economy: Between Freedom and Duty}, booktitle = {Circular Economy in Sustainable Supply Chains: A Global Perspective on Challenges, Concepts and Cases}, editor = {Fr{\"o}hlich, Elisabeth and Steinbiß, Kristina and Schmiedeknecht, Maud Helene and Loza Adaui, Cristian Rolando}, publisher = {Springer}, address = {Cham}, isbn = {978-3-031-70749-0}, doi = {https://doi.org/10.1007/978-3-031-70749-0_3}, pages = {35 -- 47}, year = {2025}, language = {en} } @inbook{LozaAdaui2025, author = {Loza Adaui, Cristian Rolando}, title = {The Principle of Regeneration in Circular Economy: Revitalising for Resilience}, booktitle = {Circular Economy in Sustainable Supply Chains: A Global Perspective on Challenges, Concepts and Cases}, editor = {Fr{\"o}hlich, Elisabeth and Steinbiß, Kristina and Schmiedeknecht, Maud Helene and Loza Adaui, Cristian Rolando}, publisher = {Springer}, address = {Cham}, isbn = {978-3-031-70749-0}, doi = {https://doi.org/10.1007/978-3-031-70749-0_4}, pages = {49 -- 60}, year = {2025}, language = {en} } @inbook{LozaAdauiSchmiedeknechtSteinbissetal.2025, author = {Loza Adaui, Cristian Rolando and Schmiedeknecht, Maud Helene and Steinbiß, Kristina and Fr{\"o}hlich, Elisabeth}, title = {Circular Economy in Sustainable Supply Chains: Presenting a Global Perspective on Challenges, Concepts and Cases}, booktitle = {Circular Economy in Sustainable Supply Chains: A Global Perspective on Challenges, Concepts and Cases}, editor = {Fr{\"o}hlich, Elisabeth and Steinbiß, Kristina and Schmiedeknecht, Maud Helene and Loza Adaui, Cristian Rolando}, publisher = {Springer}, address = {Cham}, isbn = {978-3-031-70749-0}, doi = {https://doi.org/10.1007/978-3-031-70749-0_1}, pages = {1 -- 18}, year = {2025}, language = {en} } @book{OPUS4-6688, title = {Circular Economy in Sustainable Supply Chains}, subtitle = {A Global Perspective on Challenges, Concepts and Cases}, editor = {Fr{\"o}hlich, Elisabeth and Steinbiß, Kristina and Schmiedeknecht, Maud Helene and Loza Adaui, Cristian Rolando}, publisher = {Springer}, address = {Cham}, isbn = {978-3-031-70749-0}, doi = {https://doi.org/10.1007/978-3-031-70749-0}, pages = {X, 349}, year = {2025}, language = {en} } @techreport{SchaefleDoelling2025, author = {Sch{\"a}fle, Claudia and D{\"o}lling, Hanna}, title = {Aktives Lernen in der Hochschullehre planen und f{\"o}rdern mit dem ICAP-Modell}, publisher = {BayZiel}, address = {M{\"u}nchen}, issn = {3053-2531}, doi = {10.57825/repo_in-6690}, pages = {39}, year = {2025}, abstract = {Aktivierende, studierendenzentrierte Lehr- und Lernmethoden k{\"o}nnen lernf{\"o}rderlich sein, doch ist es nicht von vornherein klar, welche Lehrmethoden sich f{\"u}r welches Lernziel am besten eignen und wie die Methoden zu vergleichen sind, so dass Studierende die Lernziele effektiv und effizient erreichen k{\"o}nnen.

SELFY is based on four pillars: Situational awareness, Resilience, Secure Data Sharing and Trust and provides three groups of tools. SACP (Situational Awareness and Collaborative Perception) tools aim at providing all CCAM actors with a comprehensive understanding of their environment, i.e., the perception of objects, such as other traffic participants and stationary objects. CRHS (Cooperative Resilience and Healing System) tools enable self-protection actions whenever a compromising situation is detected in relation to assets, vehicles, operations, or the system itself. TDMS (Trust and Data Management System) tools establish a secure and trusted environment for data in a collaborative and cooperative context, both for infrastructure and assets, as well as for citizen's data, such as drivers or pedestrians with special attention to privacy considerations. By defining a collaborative environment between the different tools to respond to new threats, risks and attacks SELFY facilitates the comprehension of new challenges in the cybersecurity aspect of CCAMs.}, language = {en} }
