“…Its intrinsic lubricity properties relate to the vast space and weak Van der Waals forces between the S-Mo-S sandwich layers and the pure positive charge on the surface, which results in the spread of electrostatic repulsion. Layers are located with the weak molecular forces and can easily slip on each other [11][12][13][14][15] . ZnO nanoparticles are highly regarded for its high surface energy, good dispersion properties, and unique electrical and thermal conductivity.…”

this study compares the tribological and thermophysical features of the lubricating oil using MoS 2 and Zno nano-additives. the average size of MoS 2 and ZnO nanoparticles were 90 nm and 30 nm, respectively. The nanoparticles were suspended using Triton X-100 in three different concentrations (0.1, 0.4 and 0.7 wt.%) in a commercial diesel oil. Tribological properties such as mass loss of the pins, friction coefficient, and worn surface morphologies and thermophysical properties such as viscosity, viscosity index, flash point and pour point of resulting nano lubricant were evaluated and compared with those of pure diesel oil. the tribological behavior of nano lubricants was evaluated using a pin-ondisc tribometer. the worn surface morphologies were observed by scanning electron microscopy. the overall results of this experiment reveal that the addition of nano-MoS 2 reduces the mass loss values of the pins in 93% due to the nano-MoS 2 lubricant effect. With 0.7 wt.% in nanoparticles content, the viscosity of MoS 2 and ZnO nano lubricants at 100 °C increased by about 9.58% and 10.14%, respectively. Pure oil containing 0.7 wt.% of each nanoparticle increased the flash point because of its small size and surface modifying behavior compared to the pure oil. Moreover, the addition of Zno nanoparticles with pure oil lubricant is more suitable than MoS 2 nanoparticles for improving the thermophysical properties of pure oil.

“…Other types of conventional nanofluids were also studied; Mousavi et al [141] conducted an experimental investigation into the viscosity measurements of MoS 2 /diesel oil nanofluid at particle concentration between 0.1 and 0.7%. The study observed that the viscosity increased by 7.04% when volume concentration was 0.7%.…”

The field of nanofluids has received interesting attention since the concept of dispersing nanoscaled particles into a fluid was first introduced in the later part of the twentieth century. This is evident from the increased number of studies related to nanofluids published annually. The increasing attention on nanofluids is primarily due to their enhanced thermophysical properties and their ability to be incorporated into a wide range of thermal applications ranging from enhancing the effectiveness of heat exchangers used in industries to solar energy harvesting for renewable energy production. Owing to the increasing number of studies relating to nanofluids, there is a need for a holistic review of the progress and steps taken in 2019 concerning their application in heat transfer devices. This review takes a retrospective look at the year 2019 by reviewing the progress made in the area of nanofluids preparation and the applications of nanofluids in various heat transfer devices such as solar collectors, heat exchangers, refrigeration systems, radiators, thermal storage systems and electronic cooling. This review aims to update readers on recent progress while also highlighting the challenges and future of nanofluids as the next-generation heat transfer fluids. Finally, a conclusion on the merits and demerits of nanofluids is presented along with recommendations for future studies that would mobilise the rapid commercialisation of nanofluids.

Nowadays, environmentally friendly lubricants are developed to meet the standards of biodegradability, toxicity and bioaccumulation potential that reduce the adverse consequences to the aquatic atmosphere compared to conventional mineral based lubricants. In this study, an attempt made to enhance the feasibility of utilizing the Mustard oil as a commercial lubricating agent by homogeneously dispersing MWCNTs as an additive. The average crystallite size, surface morphology and elements of MWCNT are characterized through XRD, SEM, EDS and FTIR techniques, respectively. The surface deformation rate of matrix material (Mg) lubricated by Mustard oil and different weight fractions of MWCNT-Mustard oil nanofluid are estimated through Nanoindentation technique. The hardness, Young's modulus and AFM topography of the interacting surface infers that the dispersed MWCNT significantly enhance the lubricating properties of Mustard oil through micro-chipping and micro-softening effect.
