Mental health and its determinants among adolescents living in families with separated or divorced parents in an urban area of Vietnam.

Background: We assessed the prevalence of stress, anxiety, and depression among adolescents living in families with separated or divorced parents in Hue City, Vietnam and identified factors associated with these conditions.

Methods: This cross-sectional study enrolled 309 adolescents, aged 12 to 17 years, living in families with separated or divorced parents in Hue City, Vietnam. The depression anxiety stress scale-21 (DASS-21) was used to measure stress, anxiety, and depression.

Synthesis and Characterization of Novel Core-Shell ZnO@SiO Nanoparticles and Application in Antibiotic and Bacteria Removal.

A novel core-shell nanomaterial, ZnO@SiO, based on rice husk for antibiotic and bacteria removal, was successfully fabricated. The ZnO@SiO nanoparticles were characterized by X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX), Fourier transform infrared (FTIR) spectroscopy, transmission electron microscopy (TEM), photoluminescence spectroscopy (PL), Brunauer-Emmett-Teller (BET) method, diffuse reflectance ultraviolet-vis (DR-UV-vis) spectroscopy, X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, and ζ-potential measurements. β-Lactam antibiotic amoxicillin (AMX) was removed using ZnO@SiO nanoparticles with an efficiency greater than 90%, while removal was higher than 91%.
