“…It was obtained from the intercept and slope from the extrapolation of the diagrams of v versus √c shown in Fig. (. The positive Sv values in Masson's equation for l-glutamine of aqueous 20% DMF + 80% water at each the temperatures, refer to consist a stronger zwitterion-zwitterion and weak solute-solute interactions [15], its means a bigger size of hydrated zwitterions of l-glutamine with low in electrostriction, on other hand, a higher positive value of v ͦ were founded with increasing temperature [3,15]. The observed positive value of v ͦ were higher than Sv, which indicate strong solute-solvent interactions than solutesolute interaction.…”

The densities () and kinematic viscosities (ν) which was converted to the absolute viscosity () from the product of the kinematic viscosity and the density of L-Glutamine have been measured at different temperatures 298.15, 303.15 and 313.15K in aqueous 20% (w/w) dimethyl formamide (DMF) under atmospheric pressure. The value of apparent molar volume (v), limiting apparent molar volume (v ͦ ) and viscosity data have been analyzed by using Jones-Dole equation, the Jones-Dole coefficients (A and B) were calculated and excess Gibbs free energy of activation of viscous flow (  ) has been obtained to throw light on the mechanism of viscous flow. The results were interpreted strong ion-solvent interactions in these systems and also structure-maker in 20% DMF + 80% water mixed solvents.

“…The model amino acids L-Valine and L-Isoleucine exist in zwitter ions in an aqueous solution under physiological conditions. These forms create synergy in an aqueous solution, on account of the possession of dipole moment in the zwitter ionic forms and influence the protein structure and stability therein [3,[16][17][18][19][20][21][22]. A series of sequential physicochemical methods and corresponding parameters namely density, molal refractive index, viscosity, surface tension, and conductance were reported for L-Valine, and L-Isoleucine in an aqueous drug solution respectively.…”

The diverse molecular interactions key to the system of the ternary composition of (Drug+ water + amino acids) were comprehended through the evaluation of physicochemical parameters namely density, viscosity, refractive index and conductance at four different (temperatures), and that of surface tension at (298.15K) held at atmospheric pressure. These aforementioned parameters were highly conclusive of the existence of significant molecular interactions in the experimental ternary system. This follows to establish that the extent of solutesolvent interactions is, but a function of solute concentration. An insight into such diverse interactions and gain in its understanding is the prime base for designing efficient drug deliveries and applications with similar interactions at its core.

“…From research points of view, it is observed that both density and ultrasonic velocity for aqueous as well non-aqueous medium [5][6][7][8][9] are very useful properties to measure the presence of solvent-solvent, solute-solute, solvent-solute interaction. For the thermo acoustical parameters and density, some works of literature are available [10][11][12][13]. Not only that recently Ankita et al [14] evaluated volumetric.…”

Density, ρ, and ultrasonic velocity, u of an anti-tuberculosis drug, isoniazid, INH in the aqueous solutions of potassium citrate, K3Cit, and sodium citrate, Na3Cit were determined at T= (298.15 to 318.15) K and, p =0.1MPa atmospheric pressure. The thermo-acoustic properties like isothermal compressibility (βT), heat capacity ratio (g), molar compression (W), acoustic impedance (Z), molar sound velocity(R), relative association (RA), intermolecular free length (Lf), relaxation time, coefficient of thermal expansion(α), and non-linearity parameters have been evaluated from ultrasonic velocity, u, and density, ρ at the studied temperature T= (298.15 to 318.15) K. The results obtained by these processes have been used to analyze the presence of intermolecular interactions existing in the solutions system (INH+Water+K3Cit/Na3Cit). The concentration and temperature effect of the solutions on intermolecular forces were studied at the same pressure
