Optimising the performance of electrocatalysts requires atomic-scale information, but it is difficult to obtain. Here, we use atom probe tomography to elucidate the 3D structure of 10 nm sized Co2FeO4 and CoFe2O4 nanoparticles during oxygen evolution reaction (OER). We reveal nanoscale spinodal decomposition in pristine Co2FeO4. The interfaces of Co-rich and Fe-rich nanodomains of Co2FeO4 become trapping sites for hydroxyl groups, contributing to a higher OER activity compared to that of CoFe2O4. However, the activity of Co2FeO4 drops considerably due to concurrent irreversible transformation towards CoIVO2 and pronounced Fe dissolution. In contrast, there is negligible elemental redistribution for CoFe2O4 after OER, except for surface structural transformation towards (FeIII, CoIII)2O3. Overall, our study provides a unique 3D compositional distribution of mixed Co-Fe spinel oxides, which gives atomic-scale insights into active sites and the deactivation of electrocatalysts during OER.","lang":"eng"}],"extern":"1","publication":"Nature Communications","issue":"1","department":[{"_id":"985"}],"type":"journal_article","keyword":["electrocatalysis","oxygen evolution reaction","cobalt spinel","electrochemical impedance spectroscopy"],"date_created":"2025-12-03T15:22:16Z"},{"page":"24190-24198","_id":"62813","publisher":"Royal Society of Chemistry (RSC)","user_id":"116779","volume":10,"status":"public","oa":"1","citation":{"short":"R.

Although these structural features are crucial for their performance, the mechanisms behind such transitions are not well understood. Herein, we describe the mechanism of transformation from layered 2D δ-MnO2 nanosheets to the scarcely reported γ-MnO2 nanocone morphology. Despite the common purpose of introducing Fe dopants to enhance the conductivity of layered manganese oxides, the Fe galvanic exchange reaction was found responsible for such coupled phase/morphology transition. Electrochemical characterization confirmed a distinct electrochemical behaviour of the nanocones, emphasizing the need to unravel the mechanism of 2D MnO2 transformation. Such mechanistic insights were gained by systematic and rigorous electron microscopy studies. The effect of the local chemical composition was determined by energy dispersive X-ray spectroscopy while electron energy loss spectroscopy unravelled the key influence of the oxidation state of Mn ions within nanosheets and nanocones. We propose and demonstrate a Mn2+-mediated oxidative mechanism of coupled morphology/phase transformation subjected to the equilibrium of Fe and Mn ions during galvanic exchange reaction. These findings contribute to the understanding of the growth and morphology/phase transformations of manganese oxide nanostructures, providing insights for the rational design of nanomaterials."}]},{"date_created":"2022-11-16T12:29:11Z","type":"journal_article","keyword":["Physics and Astronomy (miscellaneous)"],"department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"705"},{"_id":"230"},{"_id":"429"},{"_id":"35"}],"publication":"Applied Physics Letters","issue":"20","article_number":"201103","language":[{"iso":"eng"}],"doi":"10.1063/5.0093908","year":"2022","title":"Tilting nondispersive bands in an empty microcavity","author":[{"first_name":"Ying","last_name":"Gao","full_name":"Gao, Ying"},{"full_name":"Li, Yao","first_name":"Yao","last_name":"Li"},{"id":"59416","first_name":"Xuekai","last_name":"Ma","full_name":"Ma, Xuekai"},{"full_name":"Gao, Meini","first_name":"Meini","last_name":"Gao"},{"full_name":"Dai, Haitao","first_name":"Haitao","last_name":"Dai"},{"id":"27271","first_name":"Stefan","orcid":"0000-0003-4042-4951","last_name":"Schumacher","full_name":"Schumacher, Stefan"},{"last_name":"Gao","first_name":"Tingge","full_name":"Gao, Tingge"}],"publication_identifier":{"issn":["0003-6951","1077-3118"]},"publication_status":"published","date_updated":"2025-12-05T13:50:49Z","intvolume":"       121","citation":{"ieee":"Y.

In this study, a variety of electron polarons, namely free, bound, and bipolarons, are analyzed using first-principles calculations. We perform a full structural optimization based on density-functional theory for selected intrinsic defects with special attention to the role of symmetry-breaking distortions that lower the total energy. The cations hosting the various polarons relax to a different degree, with a larger relaxation corresponding to a larger gap between the defect level and the conduction-band edge. The projected density of states reveals that the polaron states are formerly empty Nb 4d states lowered into the band gap. Optical absorption spectra are derived within the independent-particle approximation, corrected by the GW approximation that yields a wider band gap and by including excitonic effects within the Bethe-Salpeter equation. Comparing the calculated spectra with the density of states, we find that the defect peak observed in the optical absorption stems from transitions between the defect level and a continuum of empty Nb 4d states. Signatures of polarons are further analyzed in the reflectivity and other experimentally measurable optical coefficients."}],"date_created":"2022-03-13T15:28:47Z","department":[{"_id":"296"},{"_id":"230"},{"_id":"429"},{"_id":"295"},{"_id":"15"},{"_id":"170"},{"_id":"35"},{"_id":"790"}],"type":"book_chapter","publication_identifier":{"eisbn":["978-3-0365-3339-1"],"isbn":["978-3-0365-3340-7"]},"author":[{"last_name":"Schmidt","orcid":"0000-0002-5071-5528","first_name":"Falko","full_name":"Schmidt, Falko","id":"35251"},{"last_name":"Kozub","orcid":"https://orcid.org/0000-0001-6584-0201","first_name":"Agnieszka L.","full_name":"Kozub, Agnieszka L.","id":"77566"},{"id":"171","full_name":"Gerstmann, Uwe","first_name":"Uwe","orcid":"0000-0002-4476-223X","last_name":"Gerstmann"},{"last_name":"Schmidt","first_name":"Wolf Gero","orcid":"0000-0002-2717-5076","full_name":"Schmidt, Wolf Gero","id":"468"},{"last_name":"Schindlmayr","first_name":"Arno","orcid":"0000-0002-4855-071X","full_name":"Schindlmayr, Arno","id":"458"}],"title":"Electron polarons in lithium niobate: Charge localization, lattice deformation, and optical response","year":"2022","publication_status":"published","date_updated":"2025-12-05T14:00:04Z","language":[{"iso":"eng"}],"doi":"10.3390/books978-3-0365-3339-1","citation":{"mla":"Schmidt, Falko, et al. “Electron Polarons in Lithium Niobate: Charge Localization, Lattice Deformation, and Optical Response.” <i>New Trends in Lithium Niobate: From Bulk to Nanocrystals</i>, edited by Gábor Corradi and László Kovács, MDPI, 2022, pp. 231–48, doi:<a href=\"https://doi.org/10.3390/books978-3-0365-3339-1\">10.3390/books978-3-0365-3339-1</a>.","ama":"Schmidt F, Kozub AL, Gerstmann U, Schmidt WG, Schindlmayr A.

However, the material dispersion of integrated platforms constitutes an obstacle that limits the performance and precision of such interferometers. At the same time, two-colour nonlinear interferometers present an important tool for metrological applications, when measurements in a certain frequency range are difficult. In this manuscript, we theoretically developed and investigated an integrated multimode two-colour SU(1,1) interferometer operating in a supersensitive mode. By ensuring the proper design of the integrated platform, we suppressed the dispersion, thereby significantly increasing the visibility of the interference pattern. The use of a continuous wave pump laser provided the symmetry between the spectral shapes of the signal and idler photons concerning half the pump frequency, despite different photon colours. We demonstrate that such an interferometer overcomes the classical phase sensitivity limit for wide parametric gain ranges, when up to 3×104 photons are generated.</jats:p>"}],"article_number":"552","language":[{"iso":"eng"}],"doi":"10.3390/sym14030552","title":"Two-Colour Spectrally Multimode Integrated SU(1,1) Interferometer","year":"2022","author":[{"first_name":"Alessandro","last_name":"Ferreri","full_name":"Ferreri, Alessandro"},{"id":"60286","first_name":"Polina R.","last_name":"Sharapova","full_name":"Sharapova, Polina R."}],"publication_identifier":{"issn":["2073-8994"]},"date_updated":"2025-12-16T11:27:11Z","publication_status":"published","intvolume":"        14"},{"citation":{"bibtex":"@article{Ebers_Ferreri_Hammer_Albert_Meier_Förstner_Sharapova_2022, title={Flexible source of correlated photons based on LNOI rib waveguides}, volume={4}, DOI={<a href=\"https://doi.org/10.1088/2515-7647/ac5a5b\">10.1088/2515-7647/ac5a5b</a>}, journal={Journal of Physics: Photonics}, publisher={IOP Publishing}, author={Ebers, Lena and Ferreri, Alessandro and Hammer, Manfred and Albert, Maximilian and Meier, Cedrik and Förstner, Jens and Sharapova, Polina R.}, year={2022}, pages={025001} }","ama":"Ebers L, Ferreri A, Hammer M, et al.

To properly use these components in the implementation of different quantum protocols, photons with different properties are required. In this paper, we theoretically demonstrate a flexible source of correlated photons built on the LNOI waveguide of a special geometry. This source is based on the parametric down-conversion (PDC) process, in which the signal and idler photons are generated at the telecom wavelength and have different spatial profiles and polarizations, but the same group velocities. Distinguishability in polarizations and spatial profiles facilitates the routing and manipulating individual photons, while the equality of their group velocities leads to the absence of temporal walk-off between photons. We show how the spectral properties of the generated photons and the number of their frequency modes can be controlled depending on the pump characteristics and the waveguide length. Finally, we discuss special regimes, in which narrowband light with strong frequency correlations and polarization-entangled Bell states are generated at the telecom wavelength.","lang":"eng"}],"date_created":"2022-03-07T09:51:50Z","type":"journal_article","keyword":["tet_topic_waveguide"],"department":[{"_id":"61"},{"_id":"230"},{"_id":"429"},{"_id":"15"},{"_id":"569"},{"_id":"170"},{"_id":"287"},{"_id":"35"},{"_id":"34"}],"year":"2022","title":"Flexible source of correlated photons based on LNOI rib waveguides","publication_identifier":{"issn":["2515-7647"]},"author":[{"full_name":"Ebers, Lena","first_name":"Lena","last_name":"Ebers","id":"40428"},{"id":"65609","full_name":"Ferreri, Alessandro","last_name":"Ferreri","first_name":"Alessandro"},{"id":"48077","full_name":"Hammer, Manfred","first_name":"Manfred","last_name":"Hammer","orcid":"0000-0002-6331-9348"},{"full_name":"Albert, Maximilian","last_name":"Albert","first_name":"Maximilian"},{"full_name":"Meier, Cedrik","orcid":"https://orcid.org/0000-0002-3787-3572","first_name":"Cedrik","last_name":"Meier","id":"20798"},{"id":"158","orcid":"0000-0001-7059-9862","first_name":"Jens","last_name":"Förstner","full_name":"Förstner, Jens"},{"id":"60286","first_name":"Polina R.","last_name":"Sharapova","full_name":"Sharapova, Polina R."}],"date_updated":"2025-12-16T11:31:04Z","publication_status":"published","intvolume":"         4","language":[{"iso":"eng"}],"doi":"10.1088/2515-7647/ac5a5b"},{"date_created":"2025-12-18T11:55:16Z","type":"journal_article","department":[{"_id":"35"},{"_id":"302"},{"_id":"321"}],"issue":"1","publication":"npj Materials Degradation","abstract":[{"lang":"eng","text":"<jats:title>Abstract</jats:title><jats:p>Pure iron is very attractive as a biodegradable implant material due to its high biocompatibility. In combination with additive manufacturing, which facilitates great flexibility of the implant design, it is possible to selectively adjust the microstructure of the material in the process, thereby control the corrosion and fatigue behavior. In the present study, conventional hot-rolled (HR) pure iron is compared to pure iron manufactured by electron beam melting (EBM). The microstructure, the corrosion behavior and the fatigue properties were studied comprehensively. The investigated sample conditions showed significant differences in the microstructures that led to changes in corrosion and fatigue properties. The EBM iron showed significantly lower fatigue strength compared to the HR iron. These different fatigue responses were observed under purely mechanical loading as well as with superimposed corrosion influence and are summarized in a model that describes the underlying failure mechanisms.</jats:p>"}],"article_number":"18","language":[{"iso":"eng"}],"doi":"10.1038/s41529-022-00226-4","title":"Corrosion fatigue behavior of electron beam melted iron in simulated body fluid","year":"2022","publication_identifier":{"issn":["2397-2106"]},"author":[{"first_name":"Steffen","last_name":"Wackenrohr","full_name":"Wackenrohr, Steffen"},{"last_name":"Torrent","first_name":"Christof Johannes Jaime","full_name":"Torrent, Christof Johannes Jaime"},{"last_name":"Herbst","first_name":"Sebastian","full_name":"Herbst, Sebastian"},{"full_name":"Nürnberger, Florian","last_name":"Nürnberger","first_name":"Florian"},{"full_name":"Krooss, Philipp","last_name":"Krooss","first_name":"Philipp"},{"full_name":"Ebbert, Christoph","last_name":"Ebbert","first_name":"Christoph","id":"7266"},{"id":"15182","first_name":"Markus","last_name":"Voigt","full_name":"Voigt, Markus"},{"full_name":"Grundmeier, Guido","last_name":"Grundmeier","first_name":"Guido","id":"194"},{"last_name":"Niendorf","first_name":"Thomas","full_name":"Niendorf, Thomas"},{"last_name":"Maier","first_name":"Hans Jürgen","full_name":"Maier, Hans Jürgen"}],"publication_status":"published","date_updated":"2025-12-18T11:56:57Z","intvolume":"         6","citation":{"bibtex":"@article{Wackenrohr_Torrent_Herbst_Nürnberger_Krooss_Ebbert_Voigt_Grundmeier_Niendorf_Maier_2022, title={Corrosion fatigue behavior of electron beam melted iron in simulated body fluid}, volume={6}, DOI={<a href=\"https://doi.org/10.1038/s41529-022-00226-4\">10.1038/s41529-022-00226-4</a>}, number={118}, journal={npj Materials Degradation}, publisher={Springer Science and Business Media LLC}, author={Wackenrohr, Steffen and Torrent, Christof Johannes Jaime and Herbst, Sebastian and Nürnberger, Florian and Krooss, Philipp and Ebbert, Christoph and Voigt, Markus and Grundmeier, Guido and Niendorf, Thomas and Maier, Hans Jürgen}, year={2022} }","ama":"Wackenrohr S, Torrent CJJ, Herbst S, et al.
