The present work reports the degradation of 4-nitrophenol using BiVO/CuO hybrid material synthesized by the precipitation of BiVO in the presence of CuO. Morphological and structural characterizations were performed using X-ray diffraction and scanning electronic microscopy coupled to energy dispersive X-ray spectroscopy. Through the calculation of the Kubelka-Munk function applied to diffuse reflectance spectrophotometry data, the hybrid material presented absorption edge of 1.

- A cost-effective, disposable microcell was developed for measuring creatinine levels using a modified screen-printed electrode that incorporates carbon black and iron (III) ions.
- The device requires only a tiny sample volume of 3 μL and works through a method involving the complexing of iron (III) ions with creatinine, followed by electrochemical analysis.
- The sensor demonstrated a reliable linear response for creatinine concentrations between 0.10 and 6.5 mmol/L, with a detection limit of 0.043 mmol/L, and successfully tested real urine samples for accuracy.
