Review of the measurement of zeta potentials in concentrated aqueous suspensions using electroacoustics

“…4 (d, e and f) show that the absorbance depends linearly on the MgO nanoparticle concentration and the data obeyed the Beer's law. A zeta potential value of (±30 mV) is the acceptable threshold value for a stable suspension [26]. Therefore, nanofluid sample with zeta potential value (absolute value) greater than or equal to the threshold is considered stable.…”

Desirable effective viscosity behaviour is an essential transport property required for the effective utilisation of nanofluids in industrial systems as well as other applications. Viscosity influences significantly the pumping power and heat transfer effectiveness in a thermal system since Reynolds and Prandtl numbers are functions of viscosity. In this study, the optimum energy required for the preparation of MgO-ethylene glycol (MgO-EG) nanofluids was determined by varying the ultrasonication energy input into the preparation process. The uniformly dispersed nanofluids were characterised and the viscosity measurements were carried out as a function of temperature (20 to Therefore, new correlation is proposed using the method of dimensional analysis and considering essential factors, including nanoparticle size, volume fraction temperature, capping layer thickness, viscosity of the base fluid, the density of base fluid and the density of nanofluid as input parameters.Furthermore, genetic algorithm-polynomial neural network (GA-PNN) and fuzzy C-means clusteringbased adaptive neuro-fuzzy inference system (FCM-ANFIS) was used to model the effective viscosity of the MgO-EG nanofluids considering the parameters mentioned above. The results of all the modelling techniques showed good agreement with the experimental data.

“…Among these methods, sonochemical preparation method is used to break the chemical bond of the solution compound. In general, formation, development, and implosive collapse of microcavities are the three steps involved in the production of nanoparticles through sonochemical method (Gandhi et al 2010 (Greenwood 2003). These are the solvents used to readily dissolve in water and they are normally added at approximately 1 wt %.…”

In this study, cupric oxide (CuO) nanoparticles were synthesized via sonochemical method. The samples were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscope, and transmission electron microscopy. The spherical CuO nanoparticles were dispersed in sodium hexametaphosphate under sonication (25 kHz) to analyze the particle size distribution and UV absorption spectra. Using these absorption spectra, we further examined the CuO nanoparticle to explore the possibility of using them as a material for applications such as solar cell and textile production.
