Electrocatalytic oxidation and amperometric determination of sulfasalazine using bimetal oxide nanoparticles-decorated graphene oxide composite modified glassy carbon electrode at neutral pH.

Cube-shaped samarium orthovanadate (SmVO) nanoparticles were interconnected with a graphene oxide sheet (GOS) using a simple and eco-friendly method to generate a SmVO@GOS nanocomposite. SmVO was characterized using various spectroscopic and microscopic techniques, which confirmed the wrapping of GOS around the SmVO nanoparticles. SmVO@GOS was then used to modify a glassy carbon electrode (GCE), which was evaluated for its electrochemical performance toward the assay of sulfasalazine (SSZ), an antibiotic drug.

Associations between Parental Factors and Children's Screen Time During the COVID-19 Pandemic in South Korea.

This study investigated how parental depression, parental self-care, family conflict, and parental fear of COVID-19 are associated with children's screen time during the COVID-19 pandemic. Data were collected online among South Korean families, resulting in 246 parents (59% fathers) with children between 6 and 12 years of age. Path analysis and multi-group structural equation modelling of fathers and mothers were conducted.

Deep eutectic solvent synthesis of iron vanadate-decorated sulfur-doped carbon nanofiber nanocomposite: electrochemical sensing tool for doxorubicin.

Detection of anticancer drug (doxorubicin) using an electrochemical sensor is developed based on a transition metal vanadate's related carbon composite material. With an environmentally friendly process, we have synthesized a metal oxide composite of iron vanadate nanoparticle assembled with sulfur-doped carbon nanofiber (FeV/SCNF). The FeV/SCNF composite was characterized using XRD, TEM, FESEM with elemental mapping, XPS and EDS.
