Phase and aggregation behaviour of double-chain cationic surfactants from the class of N -alkyl- N -alkyl?- N , N -dimethylammonium bromide surfactants

A novel viscoelastic system from a cationic surfactant and a hydrophobic counterion

“…7. The micrograph looks similar to other micrographs from the other systems, which form multilamellar vesicles [36][37][38][39][40][41][42][43][44][45]. As it appears from Fig.…”

Novel viscoelastic systems from cationic surfactants and hydrophobic counter-ions: Influence of surfactant chain length

“…5A-5D, all for the same system but with different magnifications, the vesicles have diameters ranging from 100 to about 2000 nm. The micrograph looks similar to other micrographs from other systems, which form multilamellar vesicles [20][21][22][23][24][25][26][27][28][29]. For the system C 16 TAOH/2,1-HNC [5], multilamellar vesicles have diameters ranging from 100-1200 nm, and interlamellar spacing about 60 nm.…”

“…11. To explain the dependency of storage modulus on chain length we can use the theory of Princen [25], who established a model to calculate the moduli of vesicle phases.…”

Effect of the spacer length on the association and adsorption behavior of dissymmetric gemini surfactants

“…1). To better understand the influence of molecular structure on the Krafft point, k c and k i for different homologs (our data and the data taken from the literature [29][30][31][32][33][34]) are summarized in Table 1.…”
