Article Synopsis
- Phenols are common industrial pollutants found in sectors like pharmaceuticals and agriculture, often released untreated, necessitating effective detection methods.
- Current detection techniques like spectrophotometry and chromatography are costly and complex, highlighting the need for a simpler, affordable solution.
- This study presents a new method using low-cost colorimetric paper-based sensor strips to detect phenols in water using the Folin-Ciocalteu reagent, achieving high recovery rates with promising detection limits.
In this comprehensive study, Ce-doped ZnO nanostructures were hydrothermally synthesized with varying Ce concentrations (0.5%, 1.0%, 1.

- Advanced materials for energy storage and gas sensing are being developed, with a focus on PANI@MnO@rGO ternary nanocomposites synthesized through a multi-step process.
- * The nanocomposites showed impressive results as gas sensors, particularly for NH gas, with a peak response of 15.56 at a temperature of 100°C and quick response times.
- * For supercapacitor applications, the materials demonstrated pseudocapacitive behavior with a capacitance of 185 F/g and great stability over 4000 cycles, highlighting their potential in these technologies.
Herein, we report a facile hydrothermal synthesis of MnO₂ nanoparticles anchored multi walled carbon nanotubes (MnO₂@MWCNTs) as potential anode materials for lithium-ion (Li-ion) batteries. The prepared MnO₂@MWCNTs were characterized by several techniques which confirmed the formation of MnO₂ nanoparticles anchored MWCNTs. The X-ray diffraction and Raman-scattering analyses of the prepared material further revealed the effective synthesis of MnO₂@MWCNTs.
