Background: This study aims to analyze the relationship between psychological resilience, perceived organizational support, and intention to stay among nurses. Additionally, it explores the mediating role of perceived organizational support in the relationship between psychological resilience and nurses' intention to stay. Methods: A cross-sectional survey was conducted between August and September 2023, involving 1,402 nurses from five Grade 3A hospitals in Guangdong. The survey utilized several instruments, including the General Information Questionnaire (GIQ), the Chinese version of the Connor-Davidson Resilience Scale (CD-RISC), the Chinese version of the Perceived Organizational Support Scale (POSS), and the Chinese version of the Intention to Stay Scale (ITSS). The obtained data were analyzed using descriptive statistics and Pearson's correlation coefficient, while the mediating effect of perceived organizational support was assessed using the PROCESS macro mediation model in SPSS. Results: The overall mean score for psychological resilience among nurses in the five Grade 3A hospitals in Guangdong was 60.54 ± 19.17, the overall mean score for perceived organizational support was 45.77 ± 11.49, and the mean score for intention to stay was 20.82 ± 4.65. The results of the statistical analysis revealed positive correlations between psychological resilience and intention to stay (r = 0.388, p < 0.01), between perceived organizational support and psychological resilience (r = 0.570, p < 0.01), and between perceived organizational support and intention to stay (r = 0.550, p < 0.01). Additionally, perceived organizational support was found to mediate the relationship between psychological resilience and intention to stay, with a mediation effect value of 0.067, accounting for 71.28% of the total effect. Conclusion: Psychological resilience of nursing staff directly impacts their intention to stay and indirectly influences their caring behaviors, with perceived organizational support serving as a key mediator in both relationships. Therefore, nursing managers should implement targeted interventions to enhance nurses' psychological resilience and perceived organizational support. Strengthening these factors can significantly increase nurses' intention to stay in their jobs, improve the quality of care, and contribute to building a strong and stable nursing workforce.

Developing efficient and sustainable pollution control technologies has become a research priority in the context of escalating global environmental pollution. Nano zero-valent iron (nZVI), with its high specific surface area and strong reducing power, demonstrates remarkable performance in pollutant removal. Still, its application is limited by issues such as oxidation, passivation, and particle aggregation. White rot fungi (WRF) possess a unique enzyme system that enables them to degrade a wide range of pollutants effectively, yet they face challenges such as long degradation cycles and low degradation efficiency. Despite the significant role of nZVI in pollutant remediation, most contaminated sites still rely on microbial remediation as a concurrent or ultimate treatment method to achieve remediation goals. The synergistic combination of nZVI and WRF can leverage their respective advantages, thereby enhancing pollution control efficiency. This paper reviews the mechanisms, advantages, and disadvantages of nZVI and WRF in pollution control, lists application examples, and discusses their synergistic application in pollution control, highlighting their potential in pollutant remediation and providing new insights for combined pollutant treatment. However, research on the combined use of nZVI and WRF for pollutant remediation is still relatively scarce, necessitating a deeper understanding of their synergistic potential and further exploration of their cooperative interactions.
