“…At each step of adding nanoparticles, the specimen was mixed by a magnetic stirrer for 22 min, and then, it was kept under ultrasonic vibration (Pars Nahand Co., Iran) for 22 min. In general, each nanofluid was both sonicated by ultrasonic vibrator and mixed by the stirrer for about 3 h. The procedure for preparing nanofluids has been explained extensively in our previous work (Manouchehrian Fard and Beiki 2016;Fard and Beiki 2017).…”

The solar pond is one of the usual tools used for solar energy harvesting in the world, although its low efficiency is still a big challenge. In this study, to enhance the thermal efficiency of the laboratory-scale salinity gradient solar pond, three different nanoparticles, i.e., SiO 2 , Fe 3 O 4, and ZnO, were dispersed into a salt-water solution as the based liquid. Nanoparticles' mass concentrations used in the based liquid were 0.012%, 0.036%, and 0.06%. The simulated sunlight thermal energy was supplied by a 500 W halogen lamp. The prepared nanofluids were used as lower layer of the pond. Approximately 3 days after filling the pond, the stable salinity gradient was formed and after almost 2 days of exposure to the simulated sunlight, the temperature of the pond layers reached thermal equilibrium. The results showed that lower layer temperature increased continuously with nanoparticles' concentration, for all nanofluids. Based on the measured temperature, the pond thermal performance was calculated, showing that all mentioned nanoparticles could enhance the thermal efficiency of the SGSP. The maximum lower layer temperature (~ 47 °C) and thermal efficiency enhancement ratio (35.13%) were obtained for the 0.06% ZnO nanofluid. This nanofluid showed the minimum light scattering (particle size parameter = 0.248) and transmittance (near zero) over the UV-Vis wavelength, leading to the increased thermal efficiency of the pond, as compared to the SiO 2 and Fe 3 O 4 nanofluids. In addition, using nanoparticles, the time required to reach equilibrium conditions in the pond was decreased, with the maximum of about 9 h.

In this research, the corrosion effect has been investigated on the high-cycle fatigue lifetime and the fracture behavior for the heat-treated aluminum-matrix nano-clay-composite and piston aluminum alloys. For this objective, after fabricating stir-casted nano-clay-composite, standard samples were machined and rotary bending fatigue tests were performed. To study the corrosion effect, some specimens were corroded in in the 0.00235% H 2 SO 4 solution after 200 hours and then, they were tested under cyclic bending loading. Due to increase in the hardness by adding nano-clay particles and the heat treatment, higher fatigue strength occurred, compared to the base material. Nano-clay particles shortened the fatigue lifetime; however, this effect was less in the corrosion-fatigue lifetime. Moreover, the failure mechanism was the brittle fracture behavior due to the observation of quasi-cleavage and cleavage marks.
