Summary: In this study, a hypoeutectic Al-22.5 wt pctCu sample was processed using the Electro-Magnetic Levitator on board of the International Space Station. The density, surface tension, and viscosity of the liquid sample were measured, and the temperature evolution was recorded. The results were consistent with previous experimental results and theoretical predictions, highlighting the potential of this method for building a comprehensive database of thermophysical properties of pure metals and alloys.

Summary: A hypoeutectic Al-22.5 wt pctCu sample was processed using the Electro-Magnetic Levitator on board of the International Space Station to study its melting and cooling behavior. The density, surface tension, and viscosity of the liquid sample were measured using the oscillating drop method and a high-speed camera. The results are consistent with previous experimental results and theoretical predictions, showing the potential of this method to build a comprehensive and reliable thermophysical properties database for pure metals and alloys.

Summary: In this study, the properties of sunflower, soybean, olive, and canola oils were examined periodically at different elevated temperatures. It was found that the unsaturated triglyceride in oils reacts significantly with environmental oxygen or water vapor, leading to changes in optical absorbance, viscosity, electrical impedance, and acid value. Olive oil has the lowest rate of color center and dynamic viscosity among the four oils, with the smallest pre-exponential factor and the largest activation energy. The rate constants of the acid reaction in olive oil are the highest among the four oils, with the lowest pre-exponential factor.

Summary: Vegetable oils are mainly composed of triglycerides, with potential as fuel sources but with limited research on their physicochemical properties. This study conducted a regression analysis to determine the relationship between the fatty acids in vegetable oils and their density, kinematic viscosity, flash point, low and high heating values. The regression models were validated and showed good correspondence with experimental databases.

Summary: The present study investigated the effects of V2O3 on the thermophysical properties of CaO-SiO2-Al2O3-MgO-TiO2 slags. The results showed that increasing V2O3 content led to a decrease in viscosity, while the addition of TiO2 decreased viscosity and the addition of Al2O3 increased viscosity. Furthermore, increasing V2O3 content increased the density of the slags, while increasing Al2O3 content increased surface tension and increasing TiO2 and V2O3 content decreased surface tension.

Summary: Surface active ionic liquids (SAILs) with different cation and anion structures were studied for their physicochemical properties and gas absorption capacities. SAILs with linear alkyl chains exhibited smaller molar volumes and higher viscosity compared to those with branched alkyl chains. At the liquid-air interface, SAILs had low surface tensions similar to n-alkanes. The micelles formed by SAILs in water were spherical and had lower critical micelle concentrations with a larger number of ion pairs. SAILs with larger non-polar domains showed higher absorption capacities for CO2 and N-2.

Summary: Experimental measurements were carried out on the physical properties of aqueous tetrabutylammonium-based ionic liquids, showing that density and surface tension increase with higher concentration of [TBA][Br], while dynamic viscosity increases with increasing IL concentration. The interaction between [TBA][Br] and water was found to be stronger compared to other ILs, resulting in unique trends seen in the physical properties. Additionally, the experimental data was satisfactorily correlated and compared with the calculated model.

Summary: An aerodynamic levitation technique was used to measure the surface tension, density, and viscosity of liquid zirconia, a phase of corium, at temperatures ranging from 2,715°C to 2,900°C. A second camera placed on top of the sample improved the volume estimation, allowing for a more precise determination of density. A novel post-treatment method was developed to obtain surface tension by considering multimodal oscillation frequencies. The viscosity may be slightly overestimated due to the multimode oscillation. Measurement uncertainties were estimated for all three thermophysical properties.

Summary: Conventional methods are ineffective for processing high melting temperature oxides, resulting in limited knowledge of their thermophysical properties. The electrostatic levitation furnace on the International Space Station offers a solution by minimizing sample deformation and internal flows, allowing for more accurate measurements of thermophysical properties.

Summary: This study examines the effect of temperature on surface tension in liquid alloys with a positive or negative temperature coefficient and a gravity limitation of the surface concentration in the surface-active metal constituent. It is found that the temperature coefficient depends on the combined effects of increased surface tension due to diminished segregation. The study provides equations and analysis methods based on Butler's thermodynamics for ideal surface phases. The results are illustrated using specific alloys such as Al-Zn, Sn-Bi, Ga-Bi, Ga-Pb, and Cu-Pb. The theoretical prediction of specific concave down d gamma/dT curves of liquid alloys is also made, and good estimates are obtained for systems with positive and negative temperature coefficients. However, deviations may occur during phase transitions or for systems with non-ideal behavior. (c) 2023 Published by Elsevier B.V.

Summary: This study presents a comprehensive database for the viscosity, surface tension, and density of mixtures of the diphenylmethane-based liquid organic hydrogen carrier system and cyclohexylphenylmethane. The data was measured using optical and conventional methods and calculated through molecular dynamics simulations. The research also revealed surface enrichment and orientation effects influencing the surface tension, and successfully explained the nonlinear behavior of dynamic viscosity using the extended hard sphere theory.

Summary: The interaction between industrial ladle lining bricks and secondary metallurgical slag varied based on the slag composition and temperature, leading to different wear behavior and chemical reactions. The viscosity, MgO saturation, and carbothermal reactions in slag played key roles in infiltrating the lining material. Impurities in the lining material contributed to the formation of a liquid slag phase, compromising material strength and causing loss of MgO grains.
