    Lithiated polymer coating for interface stabilization in Li6PS5Cl-based solid-state batteries with high-nickel NCM
    (2025) Shi, Bing-Xuan; Weber, Franjo; Yusim, Yuriy; Demuth, Thomas; Vettori, Kilian; Münchinger, Andreas; Titvinidze, Giorgi; Volz, Kerstin; Henss, Anja; Berger, Rüdiger; Richter, Felix H.
    Li6PS5Cl-based solid-state batteries with high-nickel LiNi0.9Mn0.05Co0.05O2 (NCM) promise higher energy density and safety than lithium-ion batteries with liquid electrolyte. However, their cycling performance is often limited by interface degradation between NCM and solid electrolyte. Here, a sulfonated polyphenylene sulfone/polyvinylpyrrolidone (sPPSLi/PVP) coating on NCM particles is presented that mitigates this issue. This uniform coating impedes direct contact between NCM and solid electrolyte, which lessens interface degradation and improves cycling performance. Electrochemical impedance spectroscopy and chronoamperometry show a reduced interface resistance and Li+-ion transport length during cycling for sPPSLi/PVP-coated NCM in Li6PS5Cl-based solid-state batteries. Additionally, the coating effectively suppresses side reactions, particularly the formation of oxygenated species, at the NCM/SE interface. Overall, sPPSLi/PVP-coated NCM shows remarkable improvements in cycling stability and rate capability, emphasizing the significance of applying polymer coatings.

    Voices in the margins : exploring the link between discrimination and adolescents’ political involvement
    (2025) Kleer, Benedikt Philipp; Abendschön, Simone; García-Albacete, Gema; Núñez, Lidia; Sánchez, David
    Political interest is one of the main determinants of political participation. Understanding the development and the mechanisms involved in forming this crucial cognitive orientation is necessary for an enhanced understanding and a successful political integration of young people. We know that political interest starts forming at an early age and that this process depends on several social characteristics, i.e., socioeconomic and immigration background have proven to be a significant element. However, the direction of the differences in the political interest of adolescents with an immigrant background compared to native adolescents is disputed. At the same time, some studies present lower political interest levels for immigrant youth, and others found higher political interest levels. Our article explores whether these inconsistent findings are related to (a) different discrimination experiences and (b) the moderation effects of these discrimination experiences on one important correlate of political interest—social participation. We expect that experiences of discrimination represent an important determinant of political interest. Despite its importance, little attention has been paid to the mechanisms by which discrimination fosters political interest. We rely on data from the Children of Immigrants Longitudinal Survey in Four European Countries (CILS4EU), allowing us to account for a wide range of discrimination experiences of youth. We use linear regression models to examine the effect of discrimination experience on political interest. From our results, both discrimination experience and social participation positively affect youth’s political interest, but neither amplifies the other effect through suggested moderation.

    Evaluating participatory monitoring in mountainous tourist regions
    (2025) Zeballos, Jazmin Campos; Valencia, Jefferson; Codalli, Fabia; Mitze, Fabian; Shagega, Frank; Weeser, Björn; Jacobs, Suzanne
    In view of the considerable impact of climate change on water resources, it is crucial to promptly address the limited availability of consistent and reliable hydrometeorological data to enable timely decision-making. HydroCrowd employs a participatory monitoring approach to collect meteorological and hydrological data in vulnerable mountainous tourist areas. This paper presents an analysis of both non-frequent and regular volunteers who participated in the project, examines the motivation behind their participation, and evaluates the advantages and disadvantages of the project’s approach to data collection. The stations, smartphone application, and data collection process received, in general, a positive response. However, the lack of reliable internet connection in some regions hinders the observation upload process, which in turn hinders the participation of volunteers. The results suggest that such projects cannot solely rely on non-frequent volunteers, such as tourists. Communities and local stakeholders are instrumental in ensuring the continuous collection of data in a timely manner for projects of this nature.

    Effects of high-flow oxygen therapy on oxygenation in dogs undergoing diagnostic bronchoscopy
    (2025) Ortlieb, Julia; Bender, Hannah; Schneider, Matthias; Tacke, Sabine; Hassdenteufel, Esther
    Introduction: Hypoxemia is a common complication during bronchoscopy and bronchoalveolar lavage (BAL). High-Flow Oxygen Therapy (HFOT) has been used to improve oxygenation and prevent periods of hypoxemia in people undergoing bronchoscopy. Objective: The main objective of this study was to evaluate the effect of HFOT on oxygenation in dogs undergoing diagnostic bronchoscopy compared to a traditional oxygen supplementation method (TOT). A secondary objective was to assess potential HFOT-related complications. Methods: Prospective randomized clinical trial. Dogs presented for diagnostic bronchoscopy were randomly assigned to receive either HFOT or TOT using nasal cannulas during the bronchoscopic procedure. Oxygenation was monitored through PaO2 measurements taken at seven time points: baseline (t0), after preoxygenation (t1), post-induction (t2), pre- and post-BAL sampling (t3 and t4), at the end of the procedure (t5), and 1 h after bronchoscopy (t6). Pre- and post-procedure thoracic radiographs were assessed for air leak syndrome or aerophagia. Results: 20 privately owned dogs presented for diagnostic bronchoscopy were included in the study (HFOT group: n = 10, TOT group: n = 10). Baseline characteristics and physiological parameters did not differ significantly between groups. Five dogs in each group showed hypoxemia (PaO2 < 80 mmHg) at baseline with 1/5 in each group having PaO2 < 60 mmHg. HFOT improved oxygenation throughout the procedure, with a significant increase in PaO2 observed after preoxygenation (P = 0.001) and at the end of the procedure (P = 0.013). Additionally, only 1/10 dogs in the HFOT group experienced hypoxemia during bronchoscopy compared to 5/10 dogs in the TOT group, and patients in the HFOT achieved numerically higher PaO2 values across all time points during the procedure (t1–t5). No serious adverse events related to HFOT were observed, although aerophagia occurred in both groups without necessitating intervention. Conclusion: HFOT can improve oxygenation and prevent episodes of hypoxemia in dogs undergoing bronchoscopy compared to traditional oxygen supplementation methods.
