Here, we employ an operando approach, combining a fast electrochemical quartz crystal microbalance with dissipation monitoring (EQCM-D), electrochemical impedance spectroscopy (EIS), and Raman spectroscopy to investigate interfacial transformations of Co3O4 nanoparticle electrodes in alkaline electrolyte. We identify two distinct regimes during the anodic sweep prior to the macroscopic OER onset. At lower potentials, the catalyst interface remains mechanically rigid while reversibly associating several OH−/H2O species per oxidized cobalt site. At higher potentials, pronounced softening of the interface occurs alongside further uptake of electrolyte species. This indicates amorphization and a ‘swelling process’ beyond simple adsorption. Notably, an electrochemical conditioning treatment can suppress mass and compliance hysteresis without affecting OER activity, suggesting that most incorporated electrolyte species do not participate in the OER. EIS further reveals that OER intermediates form well below the apparent OER onset potential. These results advance our mechanistic understanding of interfacial transformations in cobalt-based OER catalysts and establish EQCM-D as a sensitive operando technique for probing electrocatalyst transformations."}],"publication":"ChemCatChem"},{"popular_science":"1","type":"book","status":"public","abstract":[{"lang":"eng","text":"Translated from German, The Handbook of Qualitative and Quantitative Content Analysis is a comprehensive handbook which offers an application-orientated introduction to qualitative and quantitative content analysis methods.\r\n\r\nThe book provides explanations for beginners from bachelor level onwards on how to select an appropriate qualitative or quantitative content analysis method and how to use the chosen method(s) depending on research interest and amount of data.

This inverse problem is implemented as a nonlinear regression-type optimization problem, in which the simulation signals are fitted to the measurement signals. These signals consist of displacement responses in waveguides, focusing on hollow cylindrical geometries to enhance the simulation efficiency. To accelerate the optimization and reduce the number of model evaluations and wait times, we propose two novel methods. First, we introduce an adaptation of the Levenberg–Marquardt method derived from a geometrical interpretation of the least-squares optimization problem. Second, we introduce an improved objective function based on the autocorrelated envelopes of the measurement and simulation signals. Given that this study primarily relies on simulation data to quantify optimization convergence, we aggregate the expected ranges of realistic material parameters and derive their distributions to ensure the reproducibility of optimizations with proper measurements. We demonstrate the effectiveness of our objective function modification and step adaptation for various materials with isotropic material symmetry by comparing them with the Broyden–Fletcher–Goldfarb–Shanno method. In all cases, our method reduces the total number of model evaluations, thereby shortening the time to identify the material parameters.","lang":"eng"}],"publication":"Mechanical Systems and Signal Processing","language":[{"iso":"eng"}],"keyword":["Material parameter estimation","Waveguide","Nonlinear optimization","Inverse problem","Least squares"],"year":"2026","title":"A modified Levenberg–Marquardt method for estimating the elastic material parameters of polymer waveguides using residuals between autocorrelated frequency responses","date_created":"2026-01-29T08:53:42Z"},{"publisher":"MDPI AG","date_created":"2026-02-02T07:18:03Z","title":"Approximating Incoherent Monochromatic Light Sources in FDTD Simulations","quality_controlled":"1","issue":"2","year":"2026","keyword":["tet_topic_opticalantenna","tet_topic_numerics","tet_topic_meta"],"language":[{"iso":"eng"}],"publication":"Photonics","abstract":[{"lang":"eng","text":"Light-emitting diodes (LEDs) are becoming increasingly important across various sectors of the lighting industry and are being used more frequently. In the field of symbolic projection, research is increasingly focusing on implementing light modulation using energy-efficient, incoherent LEDs rather than lasers. Since light modulation in micro- and nano-optics is typically achieved through phase modulation, Finite-Difference Time-Domain (FDTD) simulations are employed for analysis. The objective of this article is to investigate different approaches for approximating incoherent monochromatic light sources within FDTD simulations. To this end, two approaches based on dipole sources are considered, as well as a method involving plane waves with modulated wavefronts based on Cosine–Fourier functions and a method based on the superposition of Gaussian beams. These methods are evaluated in terms of their accuracy using a two-dimensional double-slit configuration and are compared against a fully incoherent analytical reference."}],"oa":"1","date_updated":"2026-02-02T21:38:34Z","author":[{"full_name":"Metzner, Dominik","last_name":"Metzner","first_name":"Dominik"},{"last_name":"Potthoff","full_name":"Potthoff, Jens","first_name":"Jens"},{"first_name":"Thomas","id":"30525","full_name":"Zentgraf, Thomas","orcid":"0000-0002-8662-1101","last_name":"Zentgraf"},{"first_name":"Jens","orcid":"0000-0001-7059-9862","last_name":"Förstner","id":"158","full_name":"Förstner, Jens"}],"volume":13,"main_file_link":[{"url":"https://www.mdpi.com/2304-6732/13/2/128","open_access":"1"}],"doi":"10.3390/photonics13020128","publication_status":"published","publication_identifier":{"issn":["2304-6732"]},"citation":{"mla":"Metzner, Dominik, et al. “Approximating Incoherent Monochromatic Light Sources in FDTD Simulations.” <i>Photonics</i>, vol. 13, no. 2, 128, MDPI AG, 2026, doi:<a href=\"https://doi.org/10.3390/photonics13020128\">10.3390/photonics13020128</a>.","bibtex":"@article{Metzner_Potthoff_Zentgraf_Förstner_2026, title={Approximating Incoherent Monochromatic Light Sources in FDTD Simulations}, volume={13}, DOI={<a href=\"https://doi.org/10.3390/photonics13020128\">10.3390/photonics13020128</a>}, number={2128}, journal={Photonics}, publisher={MDPI AG}, author={Metzner, Dominik and Potthoff, Jens and Zentgraf, Thomas and Förstner, Jens}, year={2026} }","short":"D.

Post-synthetic functionalization involves nitration of phenylene moieties, reduction to amines, and ring-opening of propane or butane sultones to graft sulfonic acid groups via flexible spacers, achieving homogeneous distribution along pore walls. Post-functionalization is confirmed by powder X-ray diffraction (PXRD), revealing preserved 2D hexagonal p6mm ordering and phenylene stacking. N2 physisorption shows type IV isotherms with reduced pore volumes and pore sizes. 1H NMR is used to quantify functionalization degrees. Impedance spectroscopy on pressed pellets demonstrates proton conductivities up to 2 × 10−3 S cm−1 at 30 °C and 90% RH, depending on the functionalization degree, confirming sulfonic acid-mediated conduction.","lang":"eng"}],"publisher":"MDPI AG","date_created":"2026-02-05T09:46:20Z","title":"Proton-Conducting Sulfonated Periodic Mesoporous Organosilica","quality_controlled":"1","issue":"3","year":"2026"},{"title":"In den Tag: Eine kurze Geschichte des Aufwachens","date_updated":"2026-02-05T10:59:58Z","publisher":"Insel","date_created":"2025-12-29T10:00:07Z","author":[{"first_name":"Christoph","last_name":"Ribbat","full_name":"Ribbat, Christoph","id":"426"}],"place":"Berlin","year":"2026","citation":{"ama":"Ribbat C. <i>In den Tag: Eine kurze Geschichte des Aufwachens</i>.

However, apps often use third-party code, complicating accurate disclosures. This paper investigates how accurately current Android apps fulfill these requirements. In this work, we present a multi-layered definition of privacy-related data to correctly report data collection in Android apps. We further create a dataset of privacy-sensitive data classes that may be used as input by an Android app. This dataset takes into account data collected both through the user interface and system APIs. Based on this, we implement a semi-automated prototype that detects and labels privacy-related data collected by a given Android app. We manually examine the data safety sections of 70 Android apps to observe how data collection is reported, identifying instances of over- and under-reporting. We compare our prototype’s results with the data safety sections of 20 apps revealing reporting discrepancies. Using the results from two Messaging and Social Media apps (Signal and Instagram), we discuss how app developers under-report and over-report data collection, respectively, and identify inaccurately reported data categories. A broader study of 7,500 Android apps reveals that apps most frequently collect data that can\r\n                    <jats:italic>partially identify</jats:italic>\r\n                    users. Although system APIs consistently collect large amounts of privacy-related data, user interfaces exhibit some more diverse data collection patterns. A more focused study on various domains of apps reveals that the largest fraction of apps collecting personal data belong to the domain of\r\n                    <jats:italic>Messaging and Social Media</jats:italic>\r\n                    .

However, it is often under-reported in app data safety sections. Our results highlight the need for greater consistency in privacy-aware app development and reporting practices.\r\n                  </jats:p>"}],"file":[{"content_type":"application/pdf","relation":"main_file","success":1,"date_created":"2026-02-11T18:32:52Z","creator":"khedkarm","date_updated":"2026-02-11T18:32:52Z","file_name":"s10515-025-00589-3-1.pdf","file_id":"64127","access_level":"closed","file_size":3363479}],"ddc":["006"],"language":[{"iso":"eng"}]},{"type":"book_chapter","publication":"Semantische Phänomene lehren und lernen.
