“Background The societal challenges presented by fear related to the coronavirus disease (COVID-19) pandemic may present unique challenges for an individual's mental health. However, the moderating role of compassion in the relationship between fear of COVID-19 and mental health has not been well-studied. The present study aimed to explore the association between fear of COVID-19 and mental health, as well as test the buffering role of compassion in this relationship. Methods The participants in this study were 325 Iranian undergraduate students (228 females), aged 18–25 years, who completed questionnaires posted on social networks via a web-based platform. Results The results showed that fear of COVID-19 was positively related with physical symptoms, social function, depressive symptoms, and anxiety symptoms. The results also showed that compassion was negatively associated with phy...

The purpose of this study was to eliminate phosphate (P) from wastewater using MnFe2O4 nanoparticles. BET, TGA/DTG, FTIR, SEM, TEM, VSM, XRD and EDX/Map analyses were used to determine the MnFe2O4 surface properties. The specific surface area of the adsorbent was 196.56 m2/g and VSM analysis showed that the adsorbent has a ferromagnetic property. The maximum P sorption efficiency using MnFe2O4 (98.52%) was achieved at pH 6, temperature of 55 °C, P concentration of 10 mg/L, time of 60 min, and sorbent dosage of 2.5 g/L, which is a significant value. Also, the thermodynamic study indicated that the P sorption process is spontaneous and endothermic. Moreover, the utmost sorption capacity of P using MnFe2O4 was 39.48 mg/g. Besides, MnFe2O4 can be used for up to 6 reuse cycles with high sorption efficiency (>91%). Also, MnFe2O4 was able to remove phosphate, COD, and BOD5 from municipal waste...
