For a more sustainable future, development of competitive base metal dyads is mandatory. However, the electron transfer mechanisms from the photosensitizer to the proton reduction catalyst in base metal dyads remain so far unexplored. We study a Fe-Co dyad that exhibits photocatalytic H2 production activity using femtosecond X-ray emission spectroscopy, complemented by ultrafast optical spectroscopy and theoretical time-dependent DFT calculations, to understand the electronic and structural dynamics after photoexcitation and during the subsequent charge transfer process from the FeII photosensitizer to the cobaloxime catalyst. Using this novel approach, the simultaneous measurement of the transient Kalpha X-ray emission at the iron and cobalt K-edges in a two-colour experiment is enabled making it possible to correlate the excited state dynamics to the electron transfer processes. The methodology, therefore, provides a clear and direct spectroscopic evidence of the Fe->Co electron transfer responsible for the proton reduction activity.","lang":"eng"}],"year":"2023","status":"public","citation":{"mla":"Nowakowski, Michał, et al. “Ultrafast Two-Colour X-Ray Emission Spectroscopy Reveals Excited State Landscape in a Base Metal Dyad.” <i>Arxiv</i>, 2023.","short":"M.

The technique is illustrated on the example of symmetric linear multistep methods with matrix coefficients.","file_size":827030,"title":"Backward error analysis for conjugate symplectic methods","content_type":"application/pdf","relation":"main_file"}],"external_id":{"arxiv":["2201.03911"]},"keyword":["variational integrators","backward error analysis","Euler--Lagrange equations","multistep methods","conjugate symplectic methods"],"ddc":["510"],"language":[{"iso":"eng"}]},{"issue":"6","year":"2023","date_created":"2023-01-20T09:10:06Z","publisher":"AIP Publishing","title":"Hamiltonian Neural Networks with Automatic Symmetry Detection","publication":"Chaos","file":[{"content_type":"application/pdf","relation":"main_file","date_updated":"2023-04-26T16:20:56Z","date_created":"2023-04-26T16:20:56Z","creator":"coffen","file_size":5200111,"description":"Incorporating physical system knowledge into data-driven\nsystem identification has been shown to be beneficial.

Increasing resource efficiency is a major challenge and affects almost every aspect of social and economic life. The mobility sector in particular is responsible for a large share of primary energy consumption and is increasingly in the focus of public interest. One possibility to adress these challenges is to reduce the vehicle weight by means of lightweight construction technologies such as multi-material systems. These assemblies consist of workpieces with different mechanical and geometrical properties, which poses a major challenge for joining technology. Mechanical joining processes such as semi-tubular self-piercing riveting are often used in the production of these assemblies, but due to their process characteristics, they are rigid and can only react to changing process variables to a limited extent. One way to increase the versatility of self-piercing riveting is to superimpose a tumbling kinematics on the punch. During tumbling, an angular offset of the punch axis to the tool axis is set and the contact area between punch and workpiece is reduced. In this work, investigations were carried out to determine how the tumbling strategy, consisting of the parameters tumbling angle, tumbling onset and tumbling kinematics, affects the material flow of the rivet element.

Complex applications with high demands on safety and reliability, such as autonomous driving, are simultaneously driving the requirements for test and diagnosis of VLSI circuits. Throughout the life cycle of a microchip, uncertainties occur that affect its timing behavior. For example, weak circuit structures, aging effects, or process variations can lead to a change in the timing behavior of the circuit. While these uncertainties do not necessarily lead to a change of the functional behavior, they can lead to a reliability problem.\r\nWith modular and hybrid compaction two test instruments are presented in this work that can be used for X-tolerant test response compaction in the built-in Faster-than-At-Speed Test (FAST) which is used to detect uncertainties in VLSI circuits. One challenge for test response compaction during FAST is the high and varying X-rate at the outputs of the circuit under test. By dividing the circuit outputs into test groups and separately compacting these test groups using stochastic compactors, the modular compaction is able to handle these high and varying X-rates.\r\nTo deal with uncertainties on logic interconnects, a method for distinguishing crosstalk and process variation is presented. In current semiconductor technologies, the number of parasitic coupling capacitances between logic interconnects is growing. These coupling capacitances can lead to crosstalk, which causes increased current flow in the logic interconnects, which in turn can lead to increased electromigration. In the presented method, delay maps describing the timing behavior of the circuit outputs at different operating points are used to train artificial neural networks which classify the tested circuits into fault-free and faulty."},{"lang":"ger","text":"Immer größere Anforderungen an die Leistungsfähigkeit von Mikrochips führen zu Halbleitertechnologien mit immer kleiner werdenden Strukturgrößen. Anwendungen mit hohen Ansprüchen an Sicherheit und Zuverlässigkeit, wie z.B. das autonome Fahren, treiben gleichzeitig die Anforderungen an den Test hochintegrierter Schaltungen an. Während des gesamten Lebenszyklus eines Mikrochips kommt es zu Unsicherheiten im Zeitverhalten. So können z.B. schwache Schaltungsstrukturen, Alterungseffekte oder Prozessvariationen zu einer Veränderung des Zeitverhaltens führen. Während diese Unsicherheiten nicht zu einer Veränderung des funktionalen Verhaltens führen müssen, können sie jedoch zu einem Zuverlässigkeitsproblem führen.\r\nMit der modularen und der hybriden Kompaktierung werden in dieser Arbeit zwei Testinstrumente vorgestellt, die für die X-tolerante Testantwortkompaktierung im eingebauten Hochgeschwindigkeitstest verwendet werden können. Eine Herausforderung für die Testantwortkompaktierung während des Hochgeschwindigkeitstests ist die hohe und variierende X-Rate an den Ausgängen der zu testenden Schaltung. Durch die Einteilung der Schaltungsausgänge in Prüfgruppen und die separierte Kompaktierung der Prüfgruppen mithilfe von stochastischen Kompaktierern, können die vorgestellten Verfahren diese hohen und variierenden X-Raten verarbeiten.\r\nFür den Umgang mit Unsicherheiten auf Verbindungsleitungen der Logik-Schaltung wird ein Verfahren zur Unterscheidung von Übersprechen und Prozessvariation vorgestellt. In aktuellen Halbleitertechnologien kommt es vermehrt zu parasitären Koppelkapazitäten zwischen den Verbindungsleitungen. In dem vorgestellten Verfahren werden künstliche neuronale Netze trainiert, um die Schaltungen in fehlerfrei und fehlerhaft zu klassifizieren."}],"title":"Testinstrumente und Testdatenanalyse zur Verarbeitung von Unsicherheiten in Logikblöcken hochintegrierter Schaltungen","date_created":"2023-08-12T09:10:38Z","publisher":"Universität Paderborn","year":"2023"},{"title":"Dispersion control with integrated plasmonic metasurfaces","conference":{"location":"San Jose, USA","end_date":"2023-05-12","start_date":"2023-05-07","name":"CLEO: Fundamental Science 2023"},"doi":"10.1364/cleo_fs.2023.fth4d.3","publisher":"Optica Publishing Group","date_updated":"2023-08-14T08:22:31Z","author":[{"first_name":"René","full_name":"Geromel, René","last_name":"Geromel"},{"full_name":"Georgi, Philip","last_name":"Georgi","first_name":"Philip"},{"id":"46170","full_name":"Protte, Maximilian","last_name":"Protte","first_name":"Maximilian"},{"last_name":"Bartley","full_name":"Bartley, Tim","id":"49683","first_name":"Tim"},{"full_name":"Huang, Lingling","last_name":"Huang","first_name":"Lingling"},{"first_name":"Thomas","last_name":"Zentgraf","orcid":"0000-0002-8662-1101","full_name":"Zentgraf, Thomas","id":"30525"}],"date_created":"2023-08-14T08:19:22Z","year":"2023","citation":{"apa":"Geromel, R., Georgi, P., Protte, M., Bartley, T., Huang, L., &#38; Zentgraf, T.
