“…Numerous works have reported a biolubricant filled with cellulose [24][25][26]. Recent research which is relatively similar to our present investigation has quantified the characterization of biolubricant mixed with cellulose from plant [12,27,28]. However, the study on tribology performance and viscosity of POE-based biolubricant mixed with NDCt as an additive and Span 60 as a surfactant is yet to be explored.…”

This research is aimed at studying the stability and tribology properties of the polyol ester oil- (POE-) based biolubricant mixed with various filler loadings from microparticle of TEMPO-oxidized bacterial cellulose (NDCt) as an additive and sorbitan monostearate (Span 60) as a surfactant. Morphology, rheology, and tribology tests were conducted. The addition of NDCt and Span 60 to pure POE as a base fluid showed elevated viscosity, lower value of coefficient friction (COF), and a remarkable decrease in the wear rate (WR). The presence of 0.6 wt% NDCt and 1.8 wt% Span 60 in POE (N2S4) decreased the COF value by 79% in comparison to POE. At room temperature, this N2S4 biolubricant sample showed a higher thermal conductivity by 4% and lower WR value by 49% compared to POE. This study introduced the preparation of the ecofriendly biolubricant filled with NDCt improving the tribology properties remarkably.

“…Capturing. The stability of the biolubricant (NDCt/Span 60 in POE) as a function of time was observed using the same method that is used in the literature, photo capturing [28,30]. A conventional camera was used to capture each sample (20 ml) in a glass bottle at various time intervals for 0, 24, 48, 120, 240, and 720 h.…”

“…The most important advantage of using nano-additives in lubricants is their small size, which acts as a roller on the interface, leads to an increase in contact surfaces and reduces the wear and friction 6 . Depending on their structural properties, their size and concentration in the base fluid, nano-additives can improve the tribological and thermophysical properties of the base fluid [7][8][9] . The major problem with the use of nano-additives is agglomeration in lubrication mechanisms 10 .…”

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.

“…They can be applied as fuel substitutes for power generation [18], enhancement of mechanical properties [19], thermal conductivity, and high-voltage (HV) insulation [20]. Natural fibres have been used as fillers in lubricant oil to improve its physicochemical properties, such as viscosity [21]. However, there are not many studies on applying natural fibres as insulating oil fillers [20].…”

This study uses natural fibre, which is moisture absorbent, as an innovative and economical filler for insulating oil. Rice husk (RH) is a natural fibre known to have water-absorbing properties and used as a supplementary cementitious material. This research utilises the water-absorbing properties of RH to improve the physicochemical and dielectric properties of insulating oil. RH was refined into a fine powder at a diameter of less than 63 µm. Palm oil (PO) was synthesised with RH at concentrations of 0 g/L, 0.01 g/L, and 0.1 g/L. The moisture-absorbent properties of RH were analysed by using Fourier-transform infrared (FTIR) spectroscopy. The particle size and distribution of RH in PO were also obtained using a scanning electron microscope (SEM) and a Zeta particle analyser. The breakdown voltage (BDV) strength of PO with RH was measured according to IEC 60156, and the dielectric frequency response was investigated in the range of 102–105 Hz. RH is proven to absorb moisture from PO, as the O–H band intensity at the 3350 cm−1 is increased from the experimental results. Therefore, the mean BDV and dielectric insulation properties of PO dispersed with RH also increased accordingly.
