    Abstract Iron oxide nanomaterials are promising candidates for various electrochemical applications. However, under operating conditions high electric resistance is still limiting performance and lifetime. By incorporating the electronically conductive carbon into a nanohybrid, performance may be increased and degeneration due to delamination may be prevented, eliminating major drawbacks. For future applications, performance is an important key, but also cost-effective manufacturing suitable for scale-up must be developed. A possible approach that shows good potential for up-scale is magnetron sputtering. In this study, a systematic investigation of iron oxides produced by RF magnetron sputtering was carried out, with a focus on establishing correlations between process parameters and resulting structural properties. It was observed that increasing the process pressure was favourable with regard to porosity. Over the entire pressure range investigated, the product consisted of low-crystalline Fe

    Abstract Road traffic induced tire wear particles (TWP) attracted widespread attention due to their potential environmental impact. Here, the adsorption process of heavy metals like Pb²⁺ and Cd²⁺ on tire wear particles produced by filing (TWP-f) is studied to elucidate the underlying kinetics and thermodynamics. This work includes voltammetric experiments to investigate the concentration and temperature dependency of the adsorption. The adsorption kinetics in buffer solution spiked with heavy metals follows a pseudo-second-order rate equation involving rate-controlling boundary layer adsorption and a side-by-side intraparticle diffusion process. Meanwhile, the adsorption tendencies under the studied conditions for TWP-f were Pb²⁺ > Cd²⁺. The equilibrium adsorption data were modulated by the Langmuir, Freundlich, and Dubinin-Radushkevich (DR) isotherms. Both the Freundlich and DR isotherms were found to be feasible for describing the adsorption on TWP-f. The adsorption energy obtained from the DR isotherm is 1.6 kJ mol⁻¹ for Pb²⁺ and 2 kJ mol⁻¹ for Cd²⁺, indicating physisorption as the dominating force. According to the Freundlich isotherm, multilayer adsorption is proposed. The thermodynamic parameters show that the adsorption of Pb²⁺ and Cd²⁺ is endergonic. Due to small Gibbs enthalpy values near the thermodynamic equilibrium, the adsorption process is mainly dependent on the ambient conditions. So, close-to-nature experiments were conducted to verify the received results. Therefore, tire and road wear particles including road sediments (TRWP+RS) were added to prefiltered freshwater samples of the river Freiberger Mulde (having naturally elevated trace element concentrations). The adsorption kinetics were investigated by ICP-MS/MS emphasizing the pseudo-second-order rate equation. Moreover, it is suggested that the tire wear particles in the TRWP+RS sample are majorly responsible for the adsorption of at least Cd²⁺.

    Abstract Der Band will am Beispiel ausgewählter zeitgenössischer Gesellschaftstheorien, die bereits mehrheitlich auch in der Genderforschung rezipiert werden, zum stärker systematisierten Dialog zwischen Genderforschung und Gesellschaftstheorien einladen. Unter Bezugnahme auf gemeinsame Leitkategorien berücksichtigen die Beiträge den Entstehungskontext der behandelten Gesellschaftstheorien sowie den zeitdiagnostisch relevanten Rezeptionsrahmen und entwickeln Perspektiven, die Gender als selbstverständlichen Bestandteil von Gesellschaft(stheorien) in das jeweilige Theoriegerüst einflechten. Dabei werden der Ort von Gender in der jeweiligen Theorie ausgelotet und Ansatzpunkte für den Theorienvergleich wie auch den weiteren Dialog von Gesellschaftstheorien und Genderforschung aufgezeigt. Zielsetzungen sind, Leerstellen der Gesellschaftsanalyse hinsichtlich der komplexen Einbettung der Geschlechterverhältnisse fokussierter zu erarbeiten und Erkenntnisse und Potenziale der Genderforschung gesellschaftstheoretisch rückzubinden. Für die 2. Auflage wurden alle Texte durchgesehen und zum Teil aktualisiert.   Der Inhalt Rekonstruktionen; Integrationen; Revisionen   Die Zielgruppen Personen mit Interesse an Gesellschaftstheorien und Genderforschung   Die Herausgeberinnen Prof. Dr. Heike Kahlert ist Inhaberin des Lehrstuhls für Soziologie/Soziale Ungleichheit und Geschlecht an der Fakultät für Sozialwissenschaft der Ruhr-Universität Bochum.
