“…The standard partial molar volume (Φ ν 0 ) was obtained by the following relation: , The behavior of Φ ν 0 is regarded with respect to solute–solvent interactions. , Values of Φ ν 0 represent the real volume of solute and changes of volume due to solute–solvent interactions. − From the data of Table it follows that values of Φ ν 0 are positive and increase with temperature indicating the existence of strong solute–solvent interactions. The increase of Φ ν 0 with increase of temperature can be due to the following: (1) in surfactant solutions molecules of the surfactant destroy the solvate layer of AA, therefore transfer of some molecules of solvent to bulk phase is possible; (2) at high temperatures surfactant–water interactions become weaker, which leads to positive changes of volume. ,, From the data of Table it also follows that values of Φ ν 0 increase in the order glycine–alanine–leucine due to an increase of AA hydrophobicity.…”

The effect of L-glycine, L-alanine, and L-leucine on micellization, surface activity, and colloidal parameters of an anionic surfactant sodium alpha olefin sulfonate C 14 −C 16 in aqueous solutions at different temperatures was studied. It was shown that the hydrophobicity of the studied amino acids had great influence on behavior of physicochemical parameters. In studied systems, the electrostatic interactions between zwitterionic groups of amino acids and ions of sodium alpha olefin sulfonate C 14 −C 16 were also important.

The densities and viscosities of glycine, l-alanine, l-valine, l-threonine, and l-arginine in (0.1 to 0.4) mol·kg–1 vitamin B6 aqueous solutions were measured and studied over the entire molality range at (293.15, 303.15, 313.15, and 323.15) K and atmospheric pressure. The apparent molar volume (V ϕ), limiting partial molar volume (V ϕ 0), and limiting partial molar volume of transfer (Δtr V ϕ 0) were obtained according to the experimental density data. The viscosity data were employed to determine the viscosity B coefficients, the free energies of activation per mole of solvent (Δμ1 0⇌) and solute (Δμ2 0⇌). The influences of temperature, molality, and solute structure on these parameters were discussed in terms of molecular interactions. The contributions of the charged end group (NH3 +, COO–) and CH2 group to the limiting partial molar volumes and viscosity B coefficients were obtained through their linear correlation as a function of the number of carbon atoms in the alkyl chains of the studied amino acids.

“…In recent years, it has been reported that a mixture of surfactants as cationic, anionic or non-ionic forms stochiometric complexion [ 28 ] which could show precipitation, coalescence or aggregation, while the presence of an excess of the other component may lead to formation of mixed micelles [ 29 , 30 ]. It has also been described that the interaction between opposite charge surfactants with aromatic or aliphatic tails generates higher exothermicity (Δ H ) with lower entropy (Δ S ) of the system [ 31 , 32 ]. These changes are reflected in the different electrostatic, aliphatic or aromatic chain interactions.…”

In this study, kaempferol (0.2 m/mmol kg −1 ) dispersed cationic surfactant micelles were prepared as a function of alkyltrimethylammonium bromide (C n TAB) hydrophobicity (C = 12 to C = 16). The dispersion study of kaempferol in different C n TAB, i.e. dodecyltrimethylammonium bromide (C = 12), tetradecyltrimethylammonium bromide (C = 14) and hexadecyltrimethylammonium bromide (C = 16), was conducted with the physico-chemical properties of density, sound velocity, viscosity, surface tension, isentropic compressibility, acoustic impedance, surface excess concentration and area occupied per molecule and thermodynamic parameters Gibbs free energy, enthalpy and activation energy measured at 298.15 K. These properties were measured with varying concentration of C n TAB from 0.0260 to 0.0305 mol kg −1 in a 10% (w/w) aqueous dimethyl sulfoxide solvent system. The variations in these measured properties have been used to infer the kaempferol dispersion stability via hydrophobic–hydrophilic, hydrophilic–hydrophilic, van der Waals, hydrogen bonding and other non-covalent interactions.
