Lithium‐rich manganese‐based layered oxides (LRMOs) have been regarded as a promising category of cathode materials due to their high specific capacity on basis of joint anionic(oxygen) /cationic redox chemistry at a high voltage, thus high energy density. The anionic redox play the key and restive roles in LRMOs, contributing the extra capacity, meanwhile being associated with several unfavorable structural and electrochemical issues. This work systematically enumerates the oxygen redox mechanisms, and challenges associated with oxygen‐anion redox in LRMOs, including irreversible transition metal migration, phase transition, and the capacity/voltage decay, etc. The recent progress made in modification of LRMOs with particular emphasis to promoting the reversible oxygen redox reaction and inhibiting the irreversible oxygen release are summarized, followed by an outlook on the future rational design and development of LRMOs. This comprehensive review and perspective are expected to provide insights for the greater utilization of oxygen redox in LRMOs and other related materials. [ABSTRACT FROM AUTHOR]

Biomass three‐dimensional composite aerogels have garnered significant attention in the realm of wearable electronic skin owing to their favorable properties, including excellent human compatibility, environmentally benign degradability, and continuous porous architecture. However, conventional biomass aerogels suffer from inadequate mechanical flexibility, susceptibility to irreversible deformation under high compressive stress, and limited reusability, thereby constraining their applicability in sensing technologies. To address these limitations, this study presents the development of porous CCS/KH560/PEI/CNT‐COOH (CKPC) composite aerogels through a freeze–drying process. Chemical crosslinking was achieved using silane coupling agent (KH560) with carboxymethyl chitosan (CCS) and polyethyleneimine (PEI), while carboxylated carbon nanotubes (CNT‐COOH) were incorporated as conductive fillers. This approach successfully overcame the issues of poor mechanical properties, low elasticity, and unbalanced sensitivity‐sensing range trade‐off in chitosan‐based aerogel sensors. The results revealed that the porous CKPC aerogels exhibited a remarkable mechanical compressive strain of 86.3% while maintaining structural integrity post‐unloading. The CKPC composite aerogel‐based sensor demonstrated a high sensitivity of 42.9 within a wide strain range of 60%–76.3%, accompanied by a stable and repeatable electrical signal response across varying strains. The porous structure of the CKPC conductive aerogel sensor holds promising applications in human motion monitoring and flexible electronics. [ABSTRACT FROM AUTHOR]

Background: Maternity health management has always been the area of concern and considering, and considering its complexity and multidisciplinary, it is necessary to provide effective training for healthcare workers. Purpose: To evaluate the impact of a multidisciplinary experiential training model on the knowledge, attitude, and practice of healthcare workers in maternity health management. Patients and Methods: We conducted a novel educational model, Multidisciplinary Maternity Health Experiential Training based on Knowledge, Attitude and Practice (MMHET), which combined theoretical knowledge, practical skills, and human-centred humanistic care, offering a comprehensive offline education program supported by online teaching materials structured around knowledge graphs. Pre- and post-test surveys were used to assess the changes in participants' knowledge, attitudes, and practices. Results: From May to July 2023, a total of 322 participants attended the course, and only a small percentage had participated in experiential training. For all topics, the vast majority of participants endorsed the course, and the attitude content had the highest percentage of participants who said they agreed. Among the groups with different years of working life, the highest percentage of participants in the > 20 years group strongly endorsed the course. Conclusion: The preliminary findings indicate that the MMHET model is well-received and feasible, demonstrating its potential to enhance maternity health management education. [ABSTRACT FROM AUTHOR]

Titanium dioxide (TiO2) is an ideal photocatalyst candidate due to its high activity, low toxicity and cost, and high chemical stability. However, its practical application in photocatalysis is seriously hindered by the wide band gap energy of TiO2 and the prone recombination of electron-hole pairs. In this study, C, N doped TiO2 were supported on spent coffee grounds-derived carbon (ACG) via in situ formation, which was denoted as C, N–TiO2@ACG. The obtained C, N–TiO2@ACG exhibits increased light absorption efficiency with the band gap energy decreasing from 3.31 eV of TiO2 to 2.34 eV, a higher specific surface area of 145.8 m2/g, and reduced recombination rates attributed to the synergistic effect of a spent coffee grounds-derived carbon substrate and C, N doping. Consequently, the optimal 1:1 C, N–TiO2@ACG delivers considerable photocatalytic activity with degradation efficiencies for methylene blue (MB) reaching 96.9% within 45 min, as well as a high reaction rate of 0.06348 min−1, approximately 4.66 times that of TiO2 (0.01361 min−1). Furthermore, it also demonstrated greatly enhanced photocatalytic efficiency towards methyl orange (MO) in the presence of MB compared with a single MO solution. This work provides a feasible and universal strategy of synchronous introducing nonmetal doping and biomass-derived carbon substrates to promote the photocatalytic performance of TiO2 for the degradation of organic dyes.
