Summary: The measurement of density, viscosity, and ultrasonic speed was conducted to study the intermolecular interactions between p-chlorotoluene and alkanol. The derived excess properties and calculated partial molar volume provide insights into the extent and nature of the interactions. The results from theoretical models and correlations further illustrate the viscosity deviation and excess isentropic compressibility for these systems.

Summary: Water activities of CuCl2-MCl2-H2O (M=Mg, Ca) ternary systems and their sub-binary systems were measured at 298.15K, with results showing that the Reaction model successfully predicted the water activity and solubility in these systems. The Pitzer model and PSC model were found to be inconsistent in representing the thermodynamic properties of these systems. The study also demonstrated how the Reaction model accounted for the distribution of Cu-bearing species in relation to MgCl2 (CaCl2) molalities and the influence of electrolyte solution structure variation on macroproperties.

Summary: Density, viscosity, and ultrasonic speed of 2-chlorotoluene with methanol and ethanol binary mixtures were measured at various temperatures. The excess molar volume, deviation in viscosity, and deviation in ultrasonic speed were calculated based on the experimental data. The results showed negative excess molar volume values for the binary mixtures, but positive at higher concentrations of 2-chlorotoluene. The viscosity and ultrasonic speed deviations were positive throughout the composition range. Various correlations were analyzed to determine viscosity and ultrasonic speed values, and Nomoto's correlation was found to be highly predictive. The findings provide insights into molecular interactions and were further validated using the ab initio approach and Singh's viscosity model.

Summary: This study investigated the viscosity of (CH4 + C3H8 + C7H16) mixtures with varying heptane fractions, presenting accurate measurements and comparing them with the extended corresponding states (ECS) model. The residual entropy scaling (RES) model was also used to predict mixture viscosities, with relative deviations generally within 15% of measured values. The results highlight the need for high quality experimental data to improve current models for predicting mixture viscosities in natural gas processing.

Summary: In this paper, the co-precipitation method was used to prepare NaMgF3 and MgF2 using the leaching solution of SPL and magnesium sulfate as raw materials. The molar ratio of magnesium ion to fluorion (M/F) was found to be the decisive factor for the type of product. NaMgF3 was mainly produced when M/F < 0.33, while MgF2 gradually formed when M/F increased to 0.33-0.81, and the product became a mixture of NaMgF3 and MgF2. When M/F exceeded 0.81, MgF2 was the main product.

Summary: This study investigated the effect of PAA on viscosity by measuring the viscosity of VOSO4 + PAA + H2O ternary solution under different conditions. Various thermodynamic parameters of the PAA aqueous solution were calculated, and prediction equations based on the Eyring's theory were established to predict the viscosity of the ternary solution. The average relative deviation of 0.74% between predicted and experimental values suggests the potential use of the prediction function for the studied ternary solution.

Summary: This study analyzed and reported the variations in microstructure, diffusion of chloride ions, and chloride binding in concrete exposed to solutions containing MgSO4 and NaCl under wetting-drying cycles. The results showed that the amounts of ettringite, calcium hydroxide, gypsum, calcite, and calcium chloroaluminate varied with the depth of the concrete. The presence of MgSO4 reduced the amount of free chloride and apparent chloride diffusion coefficient due to the filling effect of ettringite. Concrete made with ordinary Portland cement exhibited higher chloride binding capacity compared to concrete made with fly ash and Portland pozzolana cement.

Summary: Pyrolytic kinetic and thermodynamic analyses of date seeds were conducted using TGA. The results showed that the pyrolysis process consists of three stages: dehydration, devolatilisation, and char formation. The kinetic evaluation was performed using the Coats-Redfern method, and the best-fit model was the Zhuravlev diffusion equation. The data obtained are valuable for understanding the pyrolysis mechanism of date seeds and can be used in the design of pyrolysis reactors.

Summary: The aim of this study was to assess the effects of ultrafiltration (UF) combined with high-pressure processing (HPP) or heat treatment on the quality of soft cheese produced from camel milk (CM) or bovine milk (BM). The results showed that UF combined with HPP at 550 MPa can increase the total solid content and gel structure of soft cheese. Compared with heat treatment, camel milk cheese is more susceptible to protein hydrolysis and has more low molecular weight bands.

Summary: Natural gums are commonly used in various industries as stabilizers, thickeners, gelling agents, and emulsifiers. They can also act as carriers for food additives and have good barrier characteristics. Microencapsulation, especially spray drying, is an effective technique for improving the dispersion of bioactive substances in food. Arabic gum is an effective and safe antimicrobial and antioxidant additive in food, but its utility in the industrial encapsulation process is currently limited.
