“…1-4. If the interactions between molecules of the components are relatively weak, the surface tension of the mixture is expected to deviate from linearity [5][6][7]. It is energetically more favourable for the component with the lower surface tension to be preferentially expelled from the bulk to the surface.…”

Results of measurement of surface tension on mixed solutions of methyl acetate and ethyl acetate with cyclohexanone and acetophenone are reported. The values are interpreted in terms of intermolecular interactions. Surface tension deviations from linear, additive values, show that the acetophenone interacts with either methyl or ethyl acetate less strongly as compared to cyclohexanone. Similarly ethyl acetate interacts less strongly with either acetophenone or cyclohexanone compared to methyl acetate. The results are interpreted in terms of the relative bulk and the polarizability of the interacting molecules.

“…[3] That information is useful for the study of intermolecular forces, molecular dynamics, process simulation and design of equipment. [4,5] Moreover, the accurate determination of n has afforded an increased interest in its theoretical and empirical correlation with properties that are difficult to measure experimentally, such as the dielectric permittivity. [6] Although there is an experimental simplicity involved in the study of refractive index, the majority of published works deals with binary mixtures.…”

The study of thermodynamic properties of solutions provides important information on existing molecular interactions between the components present in a solution. These studies are critical for testing, validation and development of theories and mathematical models. The refractometric study of a solution is a simple assessment that can contribute to the understanding of these interactions. In this context, the behaviour of the binary water and glucose mixture was studied as well as ternary mixtures of water, glucose and acetonitrile at five different temperatures in the range 293-333 K by the determination of the refractive index of the solution. Due to the weakening of the molecular interactions with the increasing of the temperature, a decreasing dependence of refractive index with temperature was observed. The addition of acetonitrile provides an increase in the refractive index indicating the formation of clusters in the solution. ARTICLE HISTORY

These mixing rule equations have been tested and validated by several researchers[17,85,86,92,93].In the present study we attempt to provide experimental measurements of the refractive indices of two ternary systems consisting of three hydrocarbon components of two-ringcomponent 1,2,3,4-Tetrahydronaphtalene (THN), one-ring component Isobutylbenzene (IBB), and an alkane n-Dodecane (C 12 ). Knowledge of THN-IBB-C 12 mixtures is of great interest for Differential Scanning Calorimetry (DSC) and Influence of Vibrations on diffusion in Liquid (IVIDIL) experiments currently taking place (on ground and in space) onboard the International Space Station (ISS) [31].…”

Optical interferometry is a non-contact method used for the imaging and measurement of the optical properties of small or large objects with nanoscale accuracy. Interferometers are essential optical systems in engineering and medical science and are generally used to measure refractive index changes, cell pathology and shape irregularities. The ability to provide quantitative, non-invasive measurements makes interferometers suitable candidates for the study of living cells in vivo and in vitro applications. In this study, a simple interferometric system capable of providing precise measurements of the refractive indices of transparent and semi-transparent mediums was designed and developed based on the Mach-Zehnder arrangement. During the development phase, the system was used to take precise measurements of the contrast factors of the three hydrocarbon components 1,2,3,4-Tetrtahydronaphtalenene (THN), Isobutylbenzen (IBB), and Dodecane (nC12), prepared in the laboratory. The results were also compared with the corresponding results obtained using the Abbemat refractometer. The results were in agreement with those obtained from both techniques as well as the results obtained from the literature, confirming the accuracy of the measurements obtained with the new system with deviations of ± 2.50×10-3. Blood analysis is a routine procedure used in medical diagnostics to confirm a patient’s condition. Measuring the optical properties of blood is difficult due to the non-homogenous nature of the blood itself. In addition, there is a lot of variation in the refractive indices reported in the literature. These are the reasons that motivated this research to develop an empirical model that can be used to predict the refractive index of human blood as a function of concentration, temperature and wavelength. The experimental measurements were conducted on mimicking phantom, that shows better stability compared to human blood, using the Abbemat Refractometer. The values obtained using the model was in substantial agreement with those obtained experimentally with standard deviations of ± 2.33×10-3. Once the accuracy of the interferometric system was confirmed, the system was used to study the refractive index and morphology of human red blood cells. The results of the analysis confirmed the system’s ability to determine refractive index and/or blood hematocrit values with appropriate clinical accuracy.
