“…However, it is important to note that very high values of YP/PV can lead to an increase in annular frictional pressure losses and equivalent circulation density (ECD), potentially causing formation fractures. The literature suggests that YP/PV values in the range of 0.75-1 lbm/100 ft 2 /cp are ideal for good cutting transportation without causing unwarranted ECD [42,43]. The addition of DES in the mud improves the cutting carrying ability by decreasing the YP/PV value closer to the optimum range, this is due to the fact that, similar to ionic liquids, DESs alter the structure of clay platelets modifying the mud rheology.…”

During drilling, almost 70% of wellbore instability issues result from the encountering of shale formations. Various additives such as salts, silicates, and polymers are used in water-based mud to enhance its shale-inhibition capability; however, such additives have certain limitations. Lately, ionic liquids and deep eutectic solvents (DES) have been used by various research groups as shale inhibitors in drilling fluid due to their biodegradability and efficacy. However, their popularity faded when a natural derivative of DES, i.e., Natural Deep Eutectic solvent (NADES), came into the picture. This research utilizes the in-house-prepared Ascorbic acid and Glycerine (AA:Gly)-based NADES as a drilling fluid additive for shale inhibition and compares its efficacy with counterpart inhibitors such as KCl, imidazolium-based ionic liquid, and Choline Chloride-based DES. The results show that 3% NADES improved the overall Yield point to Plastic viscosity ratio, with a 39.69% decline in mud cake thickness and a 28% decline in the filtrate volume of drilling mud. Along with improved drilling fluid properties, 3% NADES resulted in 77.77% shale inhibition and 87% shale recovery. Surface tension, d-spacing, zeta potential, and FESEM have been conducted to justify and elucidate the inherent mechanism behind the working of NADES as a drilling fluid additive and clay stabilizer. Thus, Ascorbic acid-based NADES is recommended as a potential non-toxic and cheap drilling fluid additive to improve drilling fluid properties and clay stability.

“…Construction of experimental factorial designs and data analysis was performed using Design Expert Software (Version 12.0.3.0, Stat-Ease Inc., Minneapolis, MN). The experimental design included different combinations of two levels (i.e., high (+1) and low levels (-1)) of four independent variables and six additional replicates at the center point, leading to the 22 runs experimental design (Kania et al, 2021;Lavecchia et al, 2015). The minimum and maximum levels of each independent variable were determined based on recommendations from previous researchers (Deng et al, 2017a;Tibolla et al, 2019;Widaningrum et al, 2015).…”

“…The value of CA of the coasting formulation on a banana epicarp in a range from 18.08 o to 88.29 o is shown in Table 1. It is noted that to gain the best coating; it is important to select a coating formulation with a low contact angle (ɵ) to generate closer to completely wetting, strong adhesion, weak cohesion, and a lipophilic condition (Andrade et al, 2014;Deng et al, 2017a).The significance of each model, independent variables, and interactions to the responses were evaluated based on the p-value, in which a p-value less than 0.05 was considered statistically significant (Kania et al, 2021). The analysis of variance (ANOVA) evaluation (Table 2) for CA showed the linear model term was significant (p-value < 0,005).…”

This study aimed to produce new edible coatings based on the mixture of sago starch, cellulose nanofiber (CNF), glycerol, and tween-80.The effect of sago starch (5–10 g of starch/100 ml of distilled water), CNF (0.5–20% w/w), glycerol (10–30% w/w), and tween-80 (0.5–10% w/w) based on sago starch concentration on contact angle (CA), water vapor permeability (WVP), oxygen permeability (PO2) and tensile strength (TS) properties of the edible coatings were optimized using factorial experimental design (2k).The result showed that the linear model for all independent variables was significant (<i>P</i><0.05) on all responses (dependent variable).The sago starch concentration depicted a significant (p < 0.001) positive effect on contact angle; CNF showed a statistically significant effect on WVP, PO2, and TS; tween-80 showed a significant effect on all dependent variables, whereas glycerol only affected WVP. The optimum concentrations of sago starch, CNF, glycerol, and tween-80 were predicted to be 5 g/100 ml distilled water, 20% w/w, 10% w/w, and 0.5% w/w based on sago starch, respectively to obtain the minimum contact angle, WVP, PO2, and the maximum TS. The predicted data for the optimized coating formulation were in good agreement with the experimental value. This work revealed that the potential of sago starch/CNF based coating formulation could be effectively produced and successfully applied for coating of food.

The novel characteristics of ionic liquids (ILs) led to an improved tribological and thermal performance. This article discusses current progress in developing ILs as neat lubricants or additives in lube oils, with a focus on ILs chemistry, synthesis, miscibility, and other relevant rheological, thermal, and tribological properties at macro to nanoscales. This article also introduces a review of lubrication mechanisms based on the tribofilm formed on the rubbing interfaces owing to tribochemical reactions among the ILs, base oil, and solid bodies, which shows key insights into anti-wear properties. ILs exhibited superior anti-wear properties compared to fully formulated oils. Notably, there was no symmetry between the friction results of ILs and their wear counterpart. Furthermore, the main challenges to further improve ILs performance for tribological applications are highlighted. Eventually, prospects for ILs tribology are suggested, which will guide the development and synthesis of ILs-based lubricants for tribological applications.
