“…In addition, the transfer molar volumes of considered vitamins have been observed to escalate with the increase in concentration of [C 4 mim][Cl] and with temperature. This can be attributed to the prevalence of effective interactions between polar groups of vitamins and [C 4 mim][Cl], thereby leading to the migration of H 2 O from hydration shells of vitamin molecules into the interior of the mixture and in turn causing an expansion in the volume of the mixture …”

“…The limiting apparent molar isentropic compressions, K 0 ϕ,s , have been estimated for domiphen bromide and semicarbazide hydrochloride in water and in aqueous maline by means of the below-manifested relation () where S k stands for the empirical slope, which indicates the nature of the assorted solute–solute interactions operating in the mixtures. The enumerated K 0 ϕ,s values are negative and are displayed in Table S4.…”

A comprehensive examination of the thermophysical properties of semicarbazide hydrochloride and domiphen bromide in water and aqueous maline solutions (maline, a deep eutectic solvent (DES) made by mixing choline chloride and malonic acid in 1:2 mol ratio) has been done by a combination of ultrasonic, volumetric, viscometric, and thermodynamic methods at the temperature range from 293.15 to 318.15 K. Exploration of molecular interactions through the procured thermophysical properties is very important because it provides an insight into the forces that are operating in the liquid mixtures. In the present study, thermophysical parameters such as apparent molar volume (V ϕ ), apparent molar isentropic compressibility (K ϕ,s ), viscosity coefficients, Hepler's constant, etc. are studied for the abovementioned drugs in water and aqueous maline solutions. The results revealed the dominance of solute−solvent interactions in the studied systems, which were found to escalate with elevation in temperature and with the concentration of maline. The results are discussed in terms of hydrophilic−hydrophilic and hydrophilic−hydrophobic interactions in these systems along with the structure breaking/making ability of the drugs. The co-sphere overlap model has been used to interpret the positive transfer values.

“…On examining the data, it is revealed that density values of the solutions increase on raising the concentration of HSA, which occurred because of an upsurge in mass per unit volume, but on raising the temperature, the values of density decrease because of thermal expansion of all of the solutions. The apparent molar volume ( V ϕ ) was calculated by means of the following equation where M signifies the molecular mass of the surfactant (kg·mol –1 ), m signifies the molal concentration of the surfactant, ρ represents the density of the solvent, and ρ° represents the solution. The empirically determined and already reported density data for (a) NLSS + H 2 O and (b) BC + H 2 O have been compared graphically in Figure a,b, respectively.…”

Density and speed of sound values of N-lauroyl sarcosine sodium salt (NLSS) and benzethonium chloride (BC) in mixed aqueous mixtures of human serum albumin (HSA) at three equidistant temperatures (298.15, 308.15, and 318.15 K) have been measured. Using density and speed of sound data, various thermodynamic and acoustic parameters like apparent molar volumes (V ϕ), partial molar volumes (V ϕ °), partial molar volumes of transfer (Δtr V ϕ °), dependence of partial molar volume on temperature, Helper’s constant, apparent molar isentropic compressibility (K ϕ,S), partial molar isentropic compressibility (K ϕ,S °), partial molar isentropic compressibility of transfer (Δtr K ϕ,S °), hydration number, and pair–triplet interaction coefficients have been determined. The cosphere overlap model was used to analyze several kinds of molecular interactions present in the studied systems, and it was found that two types of interactions were present in the studied system, i.e., ion–hydrophilic and hydrophilic–hydrophilic interactions. Negative values of Helper’s constant revealed that both NLSS and BC behave as structure breakers.
