“…8c. The silver nanoparticles exhibit tremendous thermal conductivity when added with the base fluids [14]. Further, nanoparticles decline the abrasion among the two contact surfaces due to rolling action of nanoparticles, resulting in decrease in wear at the inserts [4]; hence, a smooth surface with a small spiny teeth is identified as shown in Fig.…”

Nowadays industries are looking forward for a sustainable manufacturing. Nanofluid with minimum quantity lubrication is one technology in the areas of green manufacturing, which minimizes the pollution caused to the environments. The aim of this work was to examine the influence of silver nanoparticles-based cutting fluid with minimum quantity lubrication in turning on titanium (grade 2) by changing the environmental conditions. Taguchi's L 27 orthogonal array has been selected to execute the experimental trials. The responses considered are surface roughness, temperature and tool wear. The process parameters selected for this analysis were environment, cutting speed, feed and depth of cut. The principal component analysis was used to determine the optimal conditions in turning parameters. It was noticed that environment is the key parameter in defining the responses. Under optimal conditions, the surface roughness has been decreased by 89%, temperature has been reduced by 44% and wear on the tool has also been reduced. The tool wear and chip morphology were reviewed through scanning electron microscope for a complete study.

“…Godson et al [13,14] in their work found an increment in thermal conductivity of 80% with 0.9 vol% and 115% for 1.2 vol% of Ag nanoparticles in water. Iyahraja and Rajadurai [15], in the study on polyvinylpyrrolidone coated on silver nanoparticles dispersed in distilled water found an enhancement in thermal conductivity of 69 % with a low volume percentage of 0.1%. As proven by other researchers, Bashirnezhad et al [16] in their review article reported that the viscosity enhances with nanoparticle concentration and decreases with increase in the temperature.…”

The present work involves in determination of a suitable ratio of glycerol-water (GW) mixture for the preparation of nanofluid. The base liquid with 30% weight of glycerol is selected, based on the thermo-physical properties for dispersion of spherical cobalt (Co) nanoparticles of 80nm size, for a maximum concentration of 2% by weight. The stability investigation of prepared nanofluids is done by measuring Zeta potential and SEM imaging. The prepared cobalt nanofluid thermal conductivity is measured by maintaining 7.5pH as that concerned value has maximum Zeta potential. The maximum increment in thermal conductivity is found to be 38.4% for 2% nanofluid concentration is determined at a temperature of 60oC. The data obtained for the base liquid are in fine concurrence with the published data

“…For example, Chen et al [22] employed a seed mediated method to synthesize Au nanoparticles with different diameters and the results demonstrated that an enhanced light absorption at a low mass fraction of Au nanoparticles relative to working fluid was ascribed to LSPR. Compared to Au, Ag displayed a more attractive appeal in solar thermal energy owing to its lower price with comparable photo-thermal conversion performance [23][24][25][26]. As reported by Chen et al [27], Ag nanoparticles were fabricated by an effective seeded growth strategy with limited spaces, which promoted absorption of sunlight from the near-infrared region to the visible region.…”

Ag nanoparticles displayed a more attractive application in solar-driven interfacial evaporation for seawater desalination, but their synthesis process was expensive and detrimental to the environment due to the consumption of chemicals. In this work, we green-synthesized Ag nanoparticles using watermelon peel extract as reducing agent, while the membrane with Ag nanoparticles was prepared for solar-driven interfacial evaporation. Moreover, the evaporation performance of the membranes with different Ag nanoparticles loadings was investigated, as well as the reusability and desalination application was also explored. The experimental results showed that the membrane with Ag nanoparticles loading of 0.05 g exhibited superior evaporation performance, corresponding to the evaporation rate of 1.37 kg m −2 h −1 and the evaporation efficiency of 89.3%, respectively. In addition, the membrane with Ag nanoparticles possessed an excellent recyclability and concentration of ions in the desalinated seawater reached the potable water standard. Our research demonstrated that Ag nanoparticles green-synthesized by watermelon peel extract was an ideal candidate applied in solardriven interfacial evaporation for seawater desalination.
