“…In addition, the interacting forces between layers can be broken under both the high load and the friction heat, which is known as exfoliation [24]. This action releases numerous smaller particles that can be adsorbed onto the metal surface, reducing its effective roughness but increasing the real contact area [41,42]. Consequently, much higher friction coefficients were observed for Cloisite 15A at 40 N than at 10 N. In contrast, the sepiolite Pangel B20 may act Figures 5a,c and 6a,c shows the variation of the friction coefficient with sliding velocity within the normal load range studied for nanoclay-based ecolubricants made up of an oil mixture with a viscosity of 140.5 cSt and nanoclay concentrations of 0.5, 3.3, and 6.0 wt.%.…”

This manuscript describes a rheological and tribological study carried out on eco-friendly lubricants. These ecolubricants were made up of nanoclays as dispersed phase (a layered nanosilicate (montmorillonite Cloisite 15A) and a fiber-like nanoclay (sepiolite Pangel B20)) and vegetable-based oil as continuous phase (castor oil (CO), high oleic sunflower oil (HOSO) and their mixtures). A series of nanoclay-based ecolubricants were prepared by varying both nanoclay concentration and base oil, and thus, its viscosity. Friction and wear behaviors were assessed by using a ball-on-three plates tribometer cell. The results showed that the fiber-like sepiolite Pangel B20 yielded an important reduction in the wear scar diameter, thus revealing its potential as anti-wear and load-carrying additive in ecolubricant formulations, while Cloisite 15A proved to have friction improving properties. These anti-wear and friction reducing properties were found to be influenced by both nanoclay concentration and oil viscosity.

“…Over the past few years, there seems to be a developing interest in corn oil biodiesel as a renewable fuel option, which is increasingly being seen as a viable alternative to conventional fossil fuels. This shift in attention may be attributed to the environmental advantages associated with the use of corn oil biodiesel [1][2][3][4][5][6]. However, biodiesel is subject to many restrictions, such as insufficient cold flow properties, decreased oxidative stability, and poor electrical conductivity [7][8][9].…”

The main aim of this study is to assess the electrical characteristics pertaining to a biodiesel derived from corn oil and lubricant. The first step in the synthesis of biodiesel from corn oil involves the transesterification process. Subsequently, the biodiesel is combined with a base lubricant (20W-40T) in varying proportions, spanning from 5% to 40% of the overall volume. The measurement and analysis of biodiesel blends necessitate consideration of crucial electrical parameters, including breakdown voltage, resistivity, permittivity and electrical conductivity. The decrease in breakdown voltage, permittivity, and electrical conductivity that ensues from an increase in diameter may be attributed to the corresponding increase in diameter. Nevertheless, a positive association exists between the greater quantity of base lubricant and an elevation in resistivity. Despite the positive correlation between resistivity and diameter, this phenomenon persists. The potential cause for the enhancement of the electrical properties might be attributed to the dispersion of the fundamental lubricant.
