Numerical investigation of heat transfer and fluid flow characteristics of ternary nanofluids through convergent and divergent channels.

The characteristics of nanomaterials have garnered significant attention in recent research on natural and forced convection. This study focuses on the forced convection characteristics of ternary nanofluids within convergent and divergent channels. The ternary nanofluid comprises titanium oxide (TiO), zinc oxide (ZnO), and silver suspended in water, which serves as the base fluid.

Iron/vanadium co-doped tungsten oxide nanostructures anchored on graphitic carbon nitride sheets (FeV-WO@g-CN) as a cost-effective novel electrode material for advanced supercapacitor applications.

In this work, we studied the effect of iron (Fe) and vanadium (V) co-doping (Fe/V), and graphitic carbon nitride (g-CN) on the performance of tungsten oxide (WO) based electrodes for supercapacitor applications. The lone pair of electrons on nitrogen can improve the surface polarity of the g-CN electrode material, which may results in multiple binding sites on the surface of electrode for interaction with electrolyte ions. As electrolyte ions interact with g-CN, they quickly become entangled with FeV-WO nanostructures, and the contact between the electrolyte and the working electrode is strengthened.

Application of ZnO-NRs@Ni-foam substrate for electrochemical fingerprint of arsenic detection in water.

Arsenic (As) is the most carcinogenic and abundantly available heavy metal present in the environment. Vertically aligned ZnO nanorod (ZnO-NR) growth was achieved on metallic nickel foam substrate a wet chemical route and it was used as an electrochemical sensor towards As(iii) detection in polluted water. Crystal structure confirmation, surface morphology observation and elemental analysis of ZnO-NRs were conducted using X-ray diffraction, field-emission scanning electron microscopy and energy-dispersive X-ray spectroscopy, respectively.
