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."}],"language":[{"iso":"eng"}],"keyword":["electrocatalysis","Co3O4","EQCM-D","OER"]},{"popular_science":"1","type":"book","abstract":[{"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.

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."}],"publication":"Nanomaterials","language":[{"iso":"eng"}]},{"author":[{"full_name":"Arango-Piñeros, Santiago","last_name":"Arango-Piñeros","first_name":"Santiago"},{"first_name":"Fabian","id":"100450","full_name":"Gundlach, Fabian","last_name":"Gundlach"},{"first_name":"Robert J.","last_name":"Lemke Oliver","full_name":"Lemke Oliver, Robert J."},{"first_name":"Kevin J.","full_name":"McGown, Kevin J.","last_name":"McGown"},{"first_name":"Will","last_name":"Sawin","full_name":"Sawin, Will"},{"last_name":"Serrano López","full_name":"Serrano López, Allechar","first_name":"Allechar"},{"last_name":"Shankar","full_name":"Shankar, Arul","first_name":"Arul"},{"full_name":"Varma, Ila","last_name":"Varma","first_name":"Ila"}],"date_created":"2026-02-09T07:48:05Z","date_updated":"2026-02-09T07:49:17Z","title":"Counting number fields of fixed degree by their smallest defining polynomial","citation":{"bibtex":"@article{Arango-Piñeros_Gundlach_Lemke Oliver_McGown_Sawin_Serrano López_Shankar_Varma_2026, title={Counting number fields of fixed degree by their smallest defining polynomial}, journal={arXiv:2602.06943}, author={Arango-Piñeros, Santiago and Gundlach, Fabian and Lemke Oliver, Robert J. and McGown, Kevin J. and Sawin, Will and Serrano López, Allechar and Shankar, Arul and Varma, Ila}, year={2026} }","mla":"Arango-Piñeros, Santiago, et al. “Counting Number Fields of Fixed Degree by Their Smallest Defining Polynomial.” <i>ArXiv:2602.06943</i>, 2026.","short":"S.

Using data from a real estate corporation, we simulate the effects of a wealth tax on cash flows from the rental operations. The level of detail of the data enables us to conduct analyses at the annual, regional and year of construction level. A comparison with real estate data from other sources supports external validity. The results of the simulation show that the introduction of a wealth tax can significantly reduce the cash flow from rental operations and lead to liquidity problems. On average over all observations, a wealth tax rate of 2% leads to a negative cash flow after all costs. In general, this finding implies that growth-oriented real estate is more affected by a wealth tax in terms of liquidity than rental yield-oriented real estate. Particularly in large cities with high market values but relatively low rents, the liquidity effects can be more than three times as high as in rural or industrial regions – potentially leading to a relative loss of investment attractiveness. As a wealth tax is decoupled from rental income, the tax burden is very sensitive to market developments, including the interest rate environment. As a result, investments in residential rental real estate are exposed to additional uncertainty. This additional tax uncertainty might impair the willingness to invest and should therefore be taken into account in political discussions on the reintroduction of a wealth tax."}],"status":"public","_id":"63835","user_id":"96670","series_title":"TRR 266 Accounting for Transparency Working Paper Series No. 221","department":[{"_id":"187"}],"language":[{"iso":"eng"}]},{"author":[{"first_name":"Johannes","last_name":"Hollenbach","orcid":"0009-0006-2008-0564","id":"94632","full_name":"Hollenbach, Johannes"},{"full_name":"Schmitz, Hendrik","id":"48879","last_name":"Schmitz","first_name":"Hendrik"},{"full_name":"Tawiah, Beatrice Baaba","last_name":"Tawiah","first_name":"Beatrice Baaba"}],"date_created":"2026-02-11T09:26:04Z","date_updated":"2026-02-11T09:27:18Z","publisher":"Springer Science and Business Media LLC","doi":"10.1007/s10198-025-01884-2","title":"Life-cycle health effects of compulsory schooling","publication_identifier":{"issn":["1618-7598","1618-7601"]},"publication_status":"published","citation":{"ama":"Hollenbach J, Schmitz H, Tawiah BB.

This reaction operates at very positive potentials, where the electrocatalyst is exposed to highly oxidative conditions and prone to potential-dependent transformation of the near-surface region. While substantial evidence for such surface restructuring exists, its extent and relevance for the catalyst’s activity are unclear. We address this topic for the case of Co3O4, one of the best-known electrocatalysts exhibiting surface restructuring, by studies of epitaxial (111)-ordered electrodeposited films with combined operando X-ray surface diffraction and absorption spectroscopy, electrochemical impedance spectroscopy, and electrochemical measurements on rotating disk electrodes. Comparison of the as-prepared and annealed state of the same samples, which both are stable even under long-term oxygen evolution conditions, provides clear insight into the role of surface defects. Our results show that defect-free annealed Co3O4(111) surfaces are structurally stable over a wide potential range and hydroxylate via adsorption at surface oxygen and Co sites. Potential-induced surface restructuring of the Co3O4 lattice occurs only in the presence of surface defects, leading to the formation of the well-known nanometer-thick oxyhydroxide skin layer. The presence of this skin layer promotes oxygen evolution at low overpotentials but results in higher Tafel slopes. As a result, highly ordered Co3O4(111) surfaces are more active at high current densities than defective Co3O4 surfaces that undergo surface restructuring. These results highlight that strategies for catalyst surface defect engineering need to be application-oriented.","lang":"eng"}],"keyword":["electrocatalysis","oxygen evolution reaction","cobalt spinel","operando characterization"],"language":[{"iso":"eng"}],"publication_identifier":{"issn":["2155-5435","2155-5435"]},"publication_status":"published","citation":{"ama":"Scharf CH, Chandraraj A, Dyk K, et al.

The model interpolates between Curie-Weiss model for $s_N=1$, multi-species mean field for fixed $s_N=s$, and the 1D Ising model for each spin in its own block at $s_N=N$.\r\n  Under mild growth conditions on $s_N$, we prove a law of large numbers and a multivariate CLT with covariance given by the lattice Green's function. For instance, the high temperature CLT essentially covers the optimal range up to $s_N=o(N/(\\log N)^c)$ and the low temperature regime is new even for fixed number of blocks $s > 2$.

In this study, a quinuclidine-based catalytic monomer (QMA) was synthesized to create polymer gel dots through the process of photopolymerization that serve as a support for the catalyst. The resulting gel-bound organocatalysts were assembled within a continuous microfluidic reactor to facilitate the Baylis–Hillman reaction between various aldehydes and acrylonitrile at a temperature of 50 °C. The conversion of the product was assessed using 1H NMR spectroscopy as an offline analytical method over a duration of 8 h. The findings indicated that highly reactive aldehydes achieved conversion rates exceeding 90%, in contrast to their less reactive counterparts. Furthermore, these results were juxtaposed with previously published data derived from alternative synthetic methodologies, revealing that the continuous microfluidic reactions employing integrated organocatalysts within polymer networks exhibited significantly higher conversions with reduced reaction times (8 h) at the same temperature (50 °C). Additionally, the influence of different geometries (round, triangular, and square) of the gel dots on catalytic activity was investigated, with round and square gel dots demonstrating slightly superior performance compared with triangular gel dots, attributed to their increased surface area. Moreover, an extended reaction period of 6 days was conducted using 4-bromobenzaldehyde and acrylonitrile, resulting in a conversion rate exceeding 70%, which remained stable for 5 days before experiencing a slight decline due to product accumulation on the gel dots.","lang":"eng"}],"publication":"ACS Omega","title":"Integrating an Organocatalyst into a Polymeric Gel Framework for the Continuous Microflow Baylis–Hillman Reaction","date_created":"2026-03-10T08:23:43Z","publisher":"American Chemical Society (ACS)","year":"2026","issue":"9","quality_controlled":"1"},{"year":"2026","place":"Münster","citation":{"ama":"Fröhleke C, Habig S, Fechner S.
