“…161,162 In recent research, most research laboratories prefer the Wilhelmy plate method to analyze the surface tension of liquid samples through a Kru ¨sh K11 tensiometer at room temperature. 163 The critical concentration and particle size of nanoparticles have been executing a significant effect due to the integration of surface tension. Besides, the heightening of surface tension is mainly responsible for the van der Waals interaction between the interfaces of gas or, liquid, and is also accountable to increase the surface free energy.…”

Two new classes of gemini cationic surfactantshexanediyl-1,6-bis[(isopropylol) alkylammonium] dibromide {in the abbreviation form: C n C 6 C n [iPr-OH] and C n C 6 C n [iPr-OH] 2 ; alkyl: C n H 2n + 1 with n = 9, 10, 12 and 14}-have been synthesized by interaction of alkyl bromides with N,N 0 -di-(isopropylol)-1,6-diaminohexane and N,N,N 0 ,N 0 -tetra-(isopropylol)-1,6-diaminohexane. The surface tension, electrical conductivity, and dynamic light scattering (DLS) techniques were used to investigate the aggregation properties of the gemini cationic surfactants in aqueous solution. The formation of critical aggregates at two concentrations in an aqueous solution from obtained gemini cationic surfactants were determined via the tensiometric method. Thus, these gemini cationic surfactants start to form aggregates at concentrations well below their critical micelle concentrations (CMC). The surface properties and the binding degree (β) of the opposite ion were tested against the length of the surfactant hydrocarbon chain and the number of the isopropylol groups in the head group. By applying the DLS technique, it was explored that how the number of isopropylol groups in gemini cationic surfactants with C 12 H 25 chain affects the sizes of micelles at concentrations greater than CMC. It was discovered that the obtained gemini cationic surfactants have a biocidal character.

The electrical conductivities of aqueous solutions of the azo dye methyl orange (sodium salt) were measured at 25.0 °C in the concentration range between 2.103 × 10 -4 and 9.255 × 10 -4 mol L -1 . Molar conductivity values t the Debye-Hückel-Wager equation for a symmetric electrolyte. The value of the molar conductivity of the sodium salt of methyl orange at in nite dilution is 77.93 ± 0.38 S cm 2 mol -1 . For the anions of methyl orange, the ionic conductivity at in nite dilution was calculated to be 27.82 S cm 2 mol -1 . Using the same methodology, a thermodynamic analysis of the association between methyl orange anion and α-cyclodextrin was conducted at 20.0, 25.0, 32.0, and 40.0 °C. The measured molar conductivities decreased as the mole ratio of α-cyclodextrin to methyl orange went below 3. The conductivity measurements were analysed using a model using 1:1 stoichiometry at the four different temperatures. The values of AH o and AS o are determined, as well as a discussion of their relevance.
