Liquid temperature gradient estimation for screen channel liquid acquisition device bubble point tests in liquid nitrogen

The LAD screen utilizes surface tension forces in microgravity environments to allow liquid to flow through the screen while blocking vapor ingestion up to a certain pressure differential across the screen. The limiting pressure differential of LAD screen operation prior to bubble breakthrough is known as the bubble point pressure (ΔPBP). Previous cryogenic ΔPBP studies have identified how noncondensable pressurization decreases the interface temperature within the pores of a LAD screen via evaporative cooling and how autogenous pressurization increases the interface temperature within a LAD screen via condensation heating. The temperature gradient in the liquid side boundary layer near the screen caused by these effects has not been previously quantified. This study provides an order of magnitude analysis to show how certain variables can influence the liquid side temperature gradient during ΔPBP tests in liquid nitrogen (LN2) using noncondensable pressurization. Furthermore, cryogenic LN2ΔPBP data is taken for a 325x2300 Dutch Twill and 200x600 Dutch Twill screen with liquid side temperature measurements collected at varying distances away from the screen using dewar pressures ranging from ∼0-8psig (∼101.3-156.5kPa absolute). It has been shown that measuring the liquid screen side temperature 1/8″ (3.2 mm) away from the screen can result in a liquid side surface tension value that is ∼10-12.5% lower than the actual surface tension value at the interface for GHe tests in LN2. An empirical correlation is provided based on experimental temperature gradient data to correct historical and future ΔPBP data for the liquid screen side diode placement.

Experimental insights into the adsorption of newly synthesized Gemini ethoxylated surfactant on C-steel in different acidic media accompanied by DFT and MCs studies

Abstract Bis ethoxylated cationic surfactant (BOECS) is synthesized. The prepared surfactant’s structure configuration was verified through a variety of spectral and physicochemical techniques, including FT-IR, MS,1HNMR, and surface activity evaluations. BOECS applications as a C-steel corrosion inhibitor in 1.0 N HCl and 1.0 N H2SO4 and sulfate reducing bacteria (SRB) mitigations have been investigated thoroughly. Physical properties of the BOECS indicate its potential adsorption affinity at the air/water interface. The electrical conductivity determines the CMC value in accordance with the surface tension value. Electrochemical kinetic parameters indicate the BOECS is sorted as a mixed-type inhibitor and has an inhibition efficacy of 91.22 % and 81.26% for HCl and H2SO4, respectively. Active centers of BOECS structure enhance its adsorption at the electrolyte/C-steel. Calculated adsorption energy change (∆G ads) and theoretical adsorption energy (E ads) values suggest strong and spontaneous BOECS adsorption. The cytotoxic performance of the synthesized BOECS exhibited a potent inhibitory potential against the SRB. The outcomes of this research exhibit that the BOECS can lower SRB growth from 106 to 102 cell/mL.

Computation of thermodynamic and thermoacoustical properties of binary mixtures of ionic liquids – Applications of Flory’s statistical theory

For the first time, widely employed Flory’s statistical theory of binary liquid mixtures has been successfully applied to six binary ionic liquid mixtures. Only density and sound speed data have been used to compute a number of useful and important thermodynamic and thermoacoustical properties of DEAA + H2O, DEAS + H2O, TEAA + H2O, TEAS + H2O, TMAA + H2O and TMAS + H2O at 298.15 K. Experimental values of density and sound speed were taken from the recent work of Venkatesu et al [J P C 118B (2014) 5971].Their data are rare, very precise and accurate. The validity of FST for pure ionic liquids (RTIL’s) and their binary mixtures has been tested from the theoretical values of surface tension and sound speed. The magnitudes of sound speed, internal pressure, energy and heat of vaporization, cohesive energy density, solubility parameter and polarity factor obtained from FST demonstrate the excellent agreement with the available values of the experimental properties.

Dynamic surface stress field of the pure liquid-vapor interface subjected to the cyclic loads.

We demonstrate a methodology for computationally investigating the mechanical response of a pure molten lead surface system to the lateral mechanical cyclic loads and try to answer the following question: how does the dynamically driven liquid surface system follow the classical physics of the elastic-driven oscillation? The steady-state oscillation of the dynamic surface tension (or excess stress) under cyclic load, including the excitation of high-frequency vibration mode at different driving frequencies and amplitudes, was compared with the classical theory of a single-body driven damped oscillator. Under the highest studied frequency (50GHz) and amplitude (5%) of the load, the increase of in (mean value) dynamic surface tension could reach ∼5%. The peak and trough values of the instantaneous dynamic surface tension could reach (up to) 40% increase and (up to) 20% decrease compared to the equilibrium surface tension, respectively. The extracted generalized natural frequencies seem to be intimately related to the intrinsic timescales of the atomic temporal-spatial correlation functions of the liquids both in the bulk region and in the outermost surface layers. These insights uncovered could be helpful for quantitative manipulation of the liquid surface using ultrafast shockwaves or laser pulses.

The Effect of Ultrasound Pretreatment on Pectin Extraction from Watermelon Rind Using Microwave-Assisted Extraction

Ultrasound pretreatment and microwave-assisted extraction (MAE) techniques were used to extract pectin from watermelon rind. This work investigated the effect of the power and time of pretreatment on the yield and characteristics of the extracted pectin. Imaging studies showed that ultrasonic pretreatment changed the morphology of the raw powder, leading to a greater porosity, and facilitated the extraction process. The highest extraction yield of pectin was 19.08% (w/w), for 5 min of extraction at 500 W ultrasonic pretreatment. Ultrasonic pretreatment affected the degree of esterification and the galacturonic acid content of pectin. The galacturonic acid content of all samples was higher than 69.0%. Extraction pretreatment reduced the surface tension value of the aqueous solution of pectin and affected the foam capacity of pectin and its monosaccharidic composition. The ultrasonic pretreatment caused significant changes in pectin characteristics, such as intrinsic viscosity, viscosity average, molecular weight, ratio of homogalacturonan to rhamnogalacturonan and the water holding capacity. In addition, kinetic studies showed that a kinetic empirical model adequately describes the effect of ultrasonic pretreatment on foam stability and its half-time.

Study on the synthesis and properties of cardanol sulfonate

Abstract In this work, using the natural product cardanol and chlorosulfonic acid as the main raw materials, the anionic surfactant cardanol sulfonate (CDS) was synthesised and investigated for its surface properties and thermodynamic properties using surface tension, conductivity and fluorescence methods. In addition, the application properties of CDS, such as foaming and cleaning ability were investigated and compared with those of sodium dodecylbenzene sulfonate (SDBS). The structure of the surfactant was characterised by FTIR, 1H NMR and MS. The Krafft point of the surfactant was below 25 °C, indicating good water solubility. The CMC values were determined by surface tension, conductivity and micropolarity measurements. The obtained CMCs agreed well within the measuring accuracy. The CMC increased with increasing temperature. As a function of temperature, the following CMC values were obtained: 5.13 × 10−3 mol L−1 (25 °C), 5.63 × 10−3 mol L−1 (35 °C) and 5.77 × 10−3 mol L−1 (45 °C). The values of surface tensions at the respective CMCs were γ CMC = 44.47 mN m−1 (25 °C), 43.53 mN m−1 (35 °C), and 42.45 mN m−1 (45 °C). The application property results showed that the foaming capacity, foam stabilisation and cleaning ability of CDS and SDBS were similar to each other, indicating that CDS can be used as a raw material for commercial detergent production.

Propiedades tensoactivas y actividad emulsionante del exudado gomoso de Prosopis juliflora (Sw.) DC.

Gums exudates are macromolecules consisting of carbohydrates (majority fraction), proteins and lipids (minority fraction), with variable concentrations of minerals, polyphenols, flavonoids, tannins and other bioactive phytochemical compounds. These natural products are used as emulsifying agents in multiple industries. The surfactant properties of a new source of gum exudate produced by Prosopis juliflora (Sw.) DC. were evaluated. Additionally, water-oil dispersions prepared with this natural polymer were tested for their emulsifying capacity and stability. A Du Noüy ring tensiometer was used to determine the amphipathic behavior of the investigated gum. The gum exudate of P. juliflora tested at 0.5 % m/v, decreases the values of surface tension (49.35 dyne.cm-1) and interfacial tension (12.78 dyne.cm-1), which evidences the potential emulsifying activity (EA) of this polysaccharide. EA values of 95 % and emulsion stability of 95.8 % were obtained, suggesting that P. juliflora gum contributes to improve the capacity and speed of adsorption of molecules between the dispersed phase and continues to form a stable emulsion. The surfactant and emulsifying activity of the investigated gum is associated with the high protein content (16.89 %) and the presence of methyl groups in its structure. Therefore, the gum exudate of P. juliflora constitutes a promising source of hydrocolloids as an emulsifier that could be evaluated in the manufacture of pharmaceuticals, food and even cosmetics. Additionally, it constitutes an unexploited natural resource that would contribute to the development of the South American regional economies where this species grows.

ВЛИЯНИЕ ПОВЕРХНОСТНОГО НАТЯЖЕНИЯ НА СТРУКТУРНО-ПОВЕРХНОСТНЫЕ СВОЙСТВА ГИДРАТИРОВАННОГО ОКСИДА АЛЮМИНИЯ, ПОЛУЧЕННОГО ВЗАИМОДЕЙСТВИЕМ СОЛЕЙ АЛЮМИНИЯ С ГАЗООБРАЗНЫМ АММИАКОМ

As a result of the conducted studies, it was found that the replacement of an aqueous medium with an organic one (acetone), which has a lower value of surface tension, makes it possible to obtain a product with a significantly more developed specific surface area and specific pore volume. So, replacing water with acetone allows you to increase both Itching and Spores by almost ~ 4 times. It was found that with the initial presence of water in the pores of GOA, the average pore diameter of the dried product is 34 nm. Treatment of the synthesized sample with acetone leads to an increase in the average pore diameter of the dried product to 510 nm.

Vajinal İlaç Taşıyıcı Sistem Olarak Polivinil Alkol Nanoliflerinin Mekanik ve Mukoadezif Özelliklerinin Değerlendirilmesi

Electrospinning is a versatile and inexpensive technique to produce nanofibers. Nanofibers can be a good alternative to classical dosage forms in vaginal applications due to high surface area/volume ratio, high encapsulation efficenciacy and mucoadhesive properties. Polyvinyl alcohol (PVA) is a biocompatible, easily degradable and flexible polymer with mucoadhesive properties used in industrial, commercial and medical applications. The scope of this study is to characterize electropsun nanofibers produced with different PVA types for vaginal use. PVA nanofibers were produced using the electrospinning method. Nanofiber formulations were prepared by dissolving PVA in dimethylformamide (DMF):distilled water (1:1) solvent system. Nanofibers were produced with three different types (PVA M 13/140, PVA G 26/140 and PVA G 40/140) PVA at 5%, 7.5% and 10% concentrations. The surface tension, viscosity and conductivity properties of the polymer mixtures were measured for electrospinning process and these parametres were found suitable for nanofiber production. While the viscosity increased with increasing polymer concentration, the surface tension values were found to be close to each other since the solvent system was the same. The mechanical and the mucoadhesive properties of nanofibers were examined and compared. Mucoadhesive and mechanical properties of nanofiber formulations differed depending on molecular weight and electrospinning process. The nanofiber formulations produced with PVA M 13/140 were found suitable for vaginal applications in terms of their mechanical and mucoadhesive properties. PVA nanofibers can be a good alternative as a drug delivery system in vaginal applications.

Surface Tension of Organophosphorus Compounds: Sarin and its Surrogates

While the production and stockpiling of organophosphorus chemical warfare agents (CWAs), such as sarin, was banned three decades ago, CWAs have remained a threat. New approaches for decontamination and destruction of CWAs require detailed knowledge of their various physicochemical properties. In particular, surface tension is needed to describe the formation and evolution of hazardous aerosols when CWA liquids are dispersed in the air. Due to the extreme toxicity of sarin, most experimental studies are carried out using its surrogates─organophosphorus compounds which, while having similar structures, are much less toxic, e.g., dimethyl methylphosphonate (DMMP) and diisopropyl methylphosphonate (DIMP). However, not only for sarin, but also for its surrogates, literature data on the surface tension are scarce. Here we present experimental measurements and computational predictions of the surface tension of DMMP and DIMP. Classical molecular dynamics simulations using the Transferable Potentials for Phase Equilibria (TraPPE) force field produced an excellent agreement with the experimental results in the temperature range from 3 to 60 °C, validating the predictive capability of TraPPE. Consequently, we applied the TraPPE force field to sarin. Our modeled values for the sarin surface tension cover the range of temperatures from 0 to 85 °C, and the four experimental data points from the literature measured between 20 and 35 °C agree perfectly with our predictions. The temperature-dependent surface tension values for sarin and its surrogates obtained in our study can be used in models predicting the formation and evolution of aerosols made of these chemicals. Furthermore, our results justify the use of the TraPPE force field to derive the thermodynamic properties of other organophosphorus compounds with structures similar to the ones studied here.

Similarity characteristics in the morphology of radial viscous fingers

We conduct nonlinear simulations to investigate the radial growth of viscous fingers in a Hele–Shaw cell by performing a wide parametric study on the two dimensionless parameters that govern the dynamics. These are the viscosity contrast, A, and the effective surface tension, B, which compares the influence of surface tension with the injection rate that drives instability. It is well known that the surface tension between the fluids has a stabilizing influence on pattern formation leading to slower fingering growth and a reduced number of fingers. Moreover, the current results show that, for fixed A values, larger values of the effective surface tension lead to the formation of fingering patterns that are similar to each other. As such, the calculated interfacial shapes are larger and take longer to develop. Furthermore, the calculated shapes offer a visually striking portrait of instability evolution, and comparison to our experimental measurements highlights the close resemblance between the two with a few discrepancies pointed out. Finally, we observe how changes to the initial nearly circular interface affect both the morphology of viscous fingers and the timescale for pattern formation.

Dilute hydrochloric acid induced switching from antagonism to synergism in the binary mixed systems of cocamidopropyl betaine (CAPB) and sodium dodecyl benzene sulfonate (SDBS)

Abstract A synergism is reported in the binary mixtures of cocamidopropyl betaine (CAPB) and sodium dodecyl benzene sulfonate (SDBS) at mole fractions of 0.25, 0.50, and 0.75, in dilute hydrochloric acid solutions (∼0.05 M) HCl, at 25 °C. Such synergism is confirmed by surface tension values, critical micelle concentration (CMC), and interaction parameter values according to Holland and Rubingh’s model and the satisfaction of Hua and Rosen conditions. Surface excess (Γ) at air/water interface and the minimum area occupied by surfactant molecule (A min) also indicated a reduction in the A min of mixed CAPB/SDBS compared to single surfactants that is due to the strong electrostatic interaction between surfactants heads. The composition of CAPB/SDBS mixed micelles, the interaction parameter (β) and the micellar activity coefficients (f 1 and f 2) were evaluated from the regular solution model for these binary amphoteric/anionic mixed systems. It is clear the CAPB surfactants are converted to the cationic form by charging in the presence of HCl, which enhances the interaction between the oppositely charged CAPB and SDBS heads and overcomes the unfavourable packing between the tails predicted in pure water. Such strong interaction was also reflected on the phase behavior of CAPB/SDBS binary mixed system. Accordingly, a switching from antagonism to synergism is reported for CAPB/SDBS binary mixed system in the presence of dilute hydrochloric acid.

Experimental Investigation of the Synergistic Effect of Two Nonionic Surfactants on Interfacial Properties and Their Application in Enhanced Oil Recovery.

In chemically enhanced oil recovery (EOR), surfactants are conventionally used to lower the interfacial tension (IFT) at the water-oil interface, alter the rock wettability, and help in the emulsification of trapped oil after primary and secondary modes of recovery. A mixture of surfactants is usually more effective than a single surfactant with enhanced surface or interfacial properties. The primary objective of this study is to examine the synergistic effects of two nonionic surfactants (Tergitol 15-S-12 and PEG 600) on surface properties, such as surface tension, IFT, and wettability alteration, in the context of EOR. The optimum composition of the surfactant mixture was obtained by surface tension measurement, and it has been found that the Tergitol 15-S-12 and PEG 600 mixture shows better synergistic effect with a minimum surface tension value of 30.3 mN/m at 225 ppm concentration of Tergitol 15-S-12 and 1 wt % of PEG 600. The surfactant mixture with optimum composition shows an ultra-low IFT of 0.672 mN/m at optimum salinity. The wettability alteration study was conducted in a goniometer by observing the change of the contact angle of an oil-wet sandstone rock in the presence of the formulated chemical slugs at different concentrations, and the results show a shift in the wettability of rock from the oil-wet to the water-wet region. The wettability alteration behavior of oil-wet rock is established using X-ray diffraction analysis of sandstone rock and zeta potential measurements of the chemical slugs. The efficacy of the optimized chemical slug for EOR was checked by a core flooding experiment, and an additional recovery of 17.73% of the original oil in place was observed.

Modeling of surface phenomena of liquid Al–Ni alloys using molecular dynamics

This work presents a study on the surface tension of liquid Aluminum–Nickel (Al–Ni) alloys. Obtaining adequate values of surface tension for this system is not a simple task as these alloys present the formation of atomic clusters with short-range order at certain compositions, which dramatically influences surface tension. The Compound Forming Model predicts the influence of these clusters on surface tension, but experimental limitations have obstructed its validation due to deficient thermodynamic data. This work attempts to overcome some of these limitations by using Molecular Dynamics (MD). By comparing the obtained results from MD simulations with those of an equivalent system without clusters, it was possible to infer the role of the atomic clusters on Al–Ni surface tension. It was found that these clusters increase surface tension by decreasing the Al content at the surface. They achieve this reduction in Al content at the surface by trapping Al atoms and hindering their travel to the surface.

Hydrodynamics and gas-liquid mass transfer in an oscillatory flow reactor: Influence of liquid properties

Liquid properties, such as, surface tension and viscosity are important parameters as they control gas-liquid mass transfer in bioprocesses. An oscillatory flow reactor provided with smooth periodic constrictions (OFR-SPC) was considered to evaluate its potential for mass transfer performance in non-pure gas-liquid systems. The effect of surface tension and viscosity on the volumetric (kLa) and liquid-side mass transfer coefficients (kL), interfacial area, (a), gas holdup (εG) and bubbles’ dynamics were investigated under different operational conditions (oscillation amplitude (x0) and frequency (f) and superficial gas velocity (ug)). Two liquid phases, ethanol and sucrose aqueous solutions covering a range of surface tension and viscosity values were used. For the bubble size distribution (BSD) measurements an image analysis technique was used. A Design of Experiment (DoE) methodology was implemented in this work to establish the relation of x0, f, ug, surface tension and viscosity with kLa. According to the results, changes in the liquid properties and operational conditions showed marked effects on bubble’s size and mass transfer. However, surface tension and viscosity had no significant influence on εG, contrary to the reported for common contactors, where εG increased in the presence of ethanol and decreased at moderate/high viscosities. Moreover, it was found that increasing the oscillatory movement notably improved kL, and kLa (2–6-fold), either in ethanol or sucrose solutions, compared to common reactors, even with moderate power consumption (∼105 W m−3). This improvement resulted from the bubbles’ breakage, which originates bubbles with small and approximately the same size (homogeneous regime) enhancing a, instead, lower oscillations resulted in large bubbles (heterogeneous regime). The results demonstrate that the OFR-SPC can ensure outstanding mass transfer rates, with potential and feasibility for use in gas-liquid bioprocesses, where mass transfer and liquid properties are important.

Free energy of critical droplets-from the binodal to the spinodal.

Arguably, the main challenge of nucleation theory is to accurately evaluate the work of formation of a critical embryo in the new phase, which governs the nucleation rate. In Classical Nucleation Theory (CNT), this work of formation is estimated using the capillarity approximation, which relies on the value of the planar surface tension. This approximation has been blamed for the large discrepancies between predictions from CNT and experiments. In this work, we present a study of the free energy of formation of critical clusters of the Lennard-Jones fluid truncated and shifted at 2.5σ using Monte Carlo simulations, density gradient theory, and density functional theory. We find that density gradient theory and density functional theory accurately reproduce molecular simulation results for critical droplet sizes and their free energies. The capillarity approximation grossly overestimates the free energy of small droplets. The incorporation of curvature corrections up to the second order with the Helfrich expansion greatly remedies this and performs very well for most of the experimentally accessible regions. However, it is imprecise for the smallest droplets and largest metastabilities since it does not account for a vanishing nucleation barrier at the spinodal. To remedy this, we propose a scaling function that uses all relevant ingredients without adding fitting parameters. The scaling function reproduces accurately the free energy of the formation of critical droplets for the entire metastability range and all temperatures examined and deviates from density gradient theory by less than one kBT.

Investigations on wetting and structural behavior using CaF2-SiO2-CaO-22.5%TiO2 SMAW electrode coating for AUSC applications

This study investigates the structural behavior and high-temperature wettability of a CaF2-SiO2-CaO-22.5%TiO2 shielded metal arc welding electrode coating for advanced ultra-supercritical power plant applications. The wettability parameters were measured, including contact angle, spread area, adhesion energy, and surface tension. Extreme vertices mixture design approaches were used to develop 13 different electrode coatings. To determine the contact angle at solid/liquid interface, circular pellets were made from powder samples and heated inside the furnace at 1125°C at a constant heating rate. Young's and Boni's equations are used to calculate the surface tension value for 13 coated samples using the calculated contact angle. Adhesion energy for 13 coated samples is calculated using Dupre's equation. Phases and structural behavior of coating samples were measured by Fourier transform infrared spectroscopy and X-ray diffraction. The developed regression model estimates the impact of primary ingredients and their interaction on the calculated wettability characteristics. CaF2.SiO2, CaO.SiO2, and CaO.CaF2 binary mixture is the more favorable and substantially impacts contact angle, whereas ternary interactions of CaO.SiO2.CaF2 shows an opposite effect on contact angle. Coating numbers 2 and 10 give better wetting behavior and spread area due to the low value of contact angles. Individual ingredient shows an increasing effect on surface tension and adhesion energy. Ternary component of CaO.CaF2.SiO2 is favorable and shows an increasing impact on adhesion energy.

Analysis of a Thermodynamic Determination of the Surface Tension of a Two-Component Vapor–Liquid System

A numerical analysis is performed of a thermodynamic determination of the surface tension (ST) of a vapor–liquid binary mixture and interfacial tension (IT) between two liquid phases as the excess value of free energy ΔF of a two-phase system with and without for a phase boundary. Calculations are made in the simplest version of the lattice gas model (LGM), allowing for the interaction of nearest neighbors in a quasi-chemical approximation. Each node of a two-component mixture in the LGM system can be occupied by mixture components A + B and vacancy V. The two main ways of calculating ST, expressed in terms of different partial contributions Miq to excess free energy ΔF (where i = A, B, V are vacancies; 1 ≤ q ≤ κ, q is the number of the monolayer inside the boundary; and κ is its width), are compared, as are calculations of ST and IT as excess free energy ΔF for a lattice model with no vacancies. The ambiguity of ST and IT values depending on the type of Miq functions is obtained by calculating the temperature dependence for a flat boundary and the dependence of ST and IT on droplet size at a fixed temperature. The role of vacancies in the LGM as the main mechanical characteristic of the system under the condition of strict phase equilibrium in three equilibria (mechanical, energy, and chemical) is discussed.

Recommended Correlations for the Surface Tension of Ethers

Surface tension values for 82 ethers have been compiled from databases, books, and papers in the literature. The data were carefully screened, and finally, 2122 values were selected. Each fluid dataset has been fitted with the Guggenheim–Katayama correlation with two, four, or six adjustable parameters, except diphenyl ether, for which the data taken from different sources clearly disagree. Thus, recommended correlations are proposed for 81 ethers. The proposed correlations provide mean absolute deviations equal to or below 0.5 mN/m and mean absolute percentage deviations below 2.6% for 79 ethers. Moreover, percentage deviations below 9.5% are obtained for all the selected data of 78 ethers. The highest deviations found are due to the disagreement between the data obtained from different sources and not to an inadequate mathematical form of the correlation model. These correlations are added to the collection of those previously proposed for different fluids, including common substances, alcohols, refrigerants, organic acids, n-alkanes, and esters.

A comparative study on surface tension, diffusion coefficient and shear viscosity coefficient of liquid transition metals

Surface tensions of liquid transition metals of the 3d, 4d and 5d series have been calculated using modified Mayer’s formula involving hard sphere (HS) interaction of liquids derived from first and second order approximations of Percus–Yevick (PY) solutions of isothermal compressibility. Effective HS diameter and packing fraction are key ingredients of this study. To determine them, we have used effective pair potential derived from both Bretonnet–Silbert (BS) pseudopotential model and many body potential obtained from embedded atom method (EAM) in conjunction with variational modified hypernetted chain (VMHNC) integral equation theory of liquid structure. Calculated values of surface tension are used to evaluate transport coefficients such as diffusion and shear viscosity coefficients. Comparing with experimental and simulated data, calculated results suggest that expression derived from second order approximation of PY solution with the combination of EAM potential and VMHNC theory works better than any other combinations for the concerned systems.
