How does spacer length of imidazolium gemini surfactants control the fabrication of 2D-Langmuir films of silver-nanoparticles at the air–water interface?

Synergism between anionic double tail and zwitterionic single tail surfactants in the formation of mixed micelles and vesicles, and use of the micelle templates for the synthesis of nano-structured gold particles

“…Surfactants can play an important role in the synthesis and stabilization of metal nanoparticles (NP); they can as well control the size and shape of the NPs depending on their types and lengths [67][68][69][70][71][72]. Cationic surfactants have potential effect on the above process.…”

Effect of ionic liquid C2mimBr on rheological behavior of Gemini surfactant 12-2-12 aqueous solution

“…It seems that the cosolvent effect of C2mimBr is overwhelmed completely by other effects caused by introducing C2mimBr to the surfactant system. Correspondingly, these comprehensive effects (the strong compress effect of counter-ion Br − on the electrical double layer near hydrophilic head groups of 12-2-12, the π-π stacking among imidazole rings, the hydrogen bonding interaction between N + of [C2mim] + and water) promote the entanglement of these micelles and thus leading to the increase of shear viscosity [60].…”

Study on metal nanoparticles synthesis and orientation of gemini surfactant molecules used as stabilizer

“…It is already known that the spacer group of the gemini surfactant plays an important role for the synthesis of Au and Ag nanoparticles (NPs) and significantly controls their size and shape [9,10,15]. Yao and co-workers [10] have reported the formation of well separated spherical Au-NPs of different size in aqueous medium using alkanediyl-a,x-bis http://dx.doi.org/10.1016/j.jcis.2014.12.064 0021-9797/Ó 2014 Elsevier Inc.

“…A similar kind of bilayer formation has also been observed in CTAB. Bhattacharya and co-workers [9,15] found that shorter spacer groups in a gemini surfactant form elongated worm like micelles, whereas for longer spacer groups, a nearly spherical shape of micelles are formed, which finally determine the shape of the metal NPs.…”
