Abstract

The micellization behavior of three cationic gemini surfactants, C16H33N+(CH3)(2)(CH2)(s)N+(CH3)(2)C16H33, 2Br(-) (s = 4, 6, 10) have been studied in the presence of 1% (w/v) and 5% (w/v) polyethylene glycol-600 (PEG-600) by conductivity measurements at 300-320 K. From the conductivity data the critical micelle concentration, the degree of counterion ionization (alpha) and the thermodynamics of micellization Delta G(m)(o), Delta H-m(o), Delta S-m(o), of the gemini surfactants have been determined. The micellar parameters show a significant dependence on the spacer length and as well as amount of polymer.

The micellization studies of cationic gemini surfactant, hexanediyl-1,6-bis(dimethylcetylammonium bromide solutions by conductometric, tensiometric, dye solubilisation, FTIR and 1H NMR: The influence of adenosine and temperature

Md. Sayem Alam, A. Mohammed Siddiq, Maroof Ali

Summary: This study reports the effect of adenosine and temperature on the micellization of a cationic gemini surfactant. The results show that the addition of adenosine increases the critical micelle concentration (CMC), and increasing temperature also leads to an increase in CMC. The evaluated energetics indicate lower stability of the surfactant solution in the presence of adenosine. Further analysis confirms that there is no chemical reaction during the interaction between the gemini surfactant and adenosine.

Interaction and micellar behavior of ternary mixture of amphoteric amino sulfonate surfactant with traditional anionic and nonionic surfactants: Effect of hydrophilicity

Qing Hua Zhang, Rui Sheng, Zhao Hua Ren, Jing Huang, Yun Xiao Wang, Ben Ru Wang, Xi Lei Huang, Qin Cheng, Xue Mei Wu, Tong Bo Wang

Summary: The micellization and molecular interaction behaviors of ternary mixtures consisting of two anionic surfactants and one nonionic surfactant in aqueous solution were studied. The effect of hydrophilicity on these behaviors was also discussed. The micellization parameters and thermodynamic parameters were estimated using models based on the pseudophase separation and regular solution theories. The results showed that the mixed critical micelle concentration (cmc) value is dependent on the composition and the hydrophilicity of the nonionic surfactant. The thermodynamic data indicated that the contribution of entropy or enthalpy played a vital role in the micellization process, depending on the amount of nonionic surfactant and its hydrophilicity.

Evidence for an L3 phase in ternary deep eutectics: composition-induced L3-to-Lα transition of AOT

Oliver S. Hammond, Naomi S. Elstone, James Doutch, Peixun Li, Karen J. Edler

Summary: This study demonstrates that pure and hydrated deep eutectic solvents (DES) can form self-assembled nanostructures similar to the bicontinuous L(3) phase in ionic liquids (ILs). The addition of surfactant AOT in the DES results in the formation of the L(3) sponge phase, characterized using the Teubner-Strey model. The local structure of the DES changes with increasing solvent water content, forming large, turbid lamellar phases and an L-3-to-L-alpha transition. Multi-contrast SANS fittings reveal that the surfactant headgroup region interacts primarily with poorly-soluble Na+ at low water contents and numerically-superior [cholinium](+) at higher water contents. The modified interfacial Gaussian curvature stabilizes the lamellar morphology, allowing for an increase in the bilayer aggregation number.

These surfactants were found to start forming aggregates at concentrations well below their critical micelle concentrations (CMC), and the effect of the number of isopropylol groups on micelle sizes was explored using dynamic light scattering (DLS) technique. Additionally, the obtained gemini cationic surfactants showed biocidal character.

Controlled synthesis of gemini surfactant-capped gold nanoparticles. Gemini structure-nanoparticle properties relationship study

Martin Pisarcik, Milos Lukac, Josef Jampilek, L'udmila Paskova, Frantisek Bilka, Andrea Bilkova, Ferdinand Devinsky, Jakub Val'ko, Renata Horakova, Jan Hosek, Matej Brezina, Tomas Opravil

Summary: Gold nanoparticles were prepared and stabilized using Gemini surfactants with varying lengths of poly-methylene spacer. The size of the nanoparticles was found to be influenced by the spacer length of the stabilizing surfactants. Short spacer lengths led to aggregation and larger particle clusters, while longer spacer lengths resulted in smaller nanoparticles. The shape of the gold nanoparticles was observed to be spherical and polyhedral. The nanoparticles exhibited positive zeta potential values and their biological activity was found to be dependent on the spacer length of the stabilizing molecules.

Using Polymer-Surfactant Charge Ratio to Control Synergistic Flocculation of Anionic Particulate Dispersions

Christopher Hill, Wasiu Abdullahi, Martin Crossman, Peter Charles Griffiths

Summary: This study investigates how the destabilization of particulate dispersions is influenced by oppositely charged polymer-surfactant complexes. The results show that complexes with a charge ratio greater than 1 enhance the destabilization, while complexes with a charge ratio less than 1 do not show adsorption and destabilization. This study highlights the possibility of controlling the interactions between polymer-surfactant complexes and particle surfaces by modulating the charge ratio.

Summary: This paper evaluates the stability of unencapsulated flexible perovskite solar cells against fast neutron irradiation at two different fluence levels. Both commercially available spiro-OMeTAD and an inhouse modified P3HT as the hole transport materials degrade under neutron irradiation. However, the modified P3HT cells show smaller voltage and current losses compared to spiro-OMeTAD cells, indicating their potential resilience. Further investigations are needed to improve the perovskite/polymer interface and promote the development of flexible perovskite solar cells for space and avionic applications.
