Constitutive modeling of dilute wormlike micelle solutions: shear-induced structure and transient dynamics [PDF]
We present a reformulation of the 'reactive rod model' (RRM) of Dutta and Graham [Dutta, Sarit and Graham, Michael D., JNNFM 251 (2018)], a constitutive model for describing the behavior of dilute wormlike micelle solutions. The RRM treats wormlike micelle solutions as dilute suspensions of rigid Brownian rods undergoing reversible scission and growth ...

The surface adsorption, aggregate structure and antibacterial activity of Gemini quaternary ammonium surfactants with carboxylic counterions [PDF]
A group of Gemini quaternary ammonium surfactants with the formula CnH2n+1CONH(CH2)2N+(CH3)2(CH2)2N+(CH3)2(CH2)2 NHCOCnH2n+1 · 2Y (n = 11, 13 and 15, Y = HCOO−, CH3COO− and CH3CHOHCOO−) have been synthesized by a counterion conversion process and ...

Colloid-chemical properties of surfactant–nitric acid–water systems
The behavior of the surfactants Tween 80, SaS and alkyl betaine in aqueous and nitric acid environments as promising additives for nitrate leaching of hard-to-process ore concentrates of non-ferrous metals was studied.

Structure formation in binary mixtures of surfactants: vesicle opening-up to bicelles and octopus-like micelles [PDF]
Micelle formation in binary mixtures of surfactants is studied using a coarse-grained molecular simulation. When a vesicle composed of lipid and detergent types of molecules is ruptured, a disk-shaped micelle, the bicelle, is typically formed. It is found that cup-shaped vesicles and bicelles connected with worm-like micelles are also formed depending ...

Self-consistent field theory for obligatory coassembly [PDF]
We present a first-order model for obligatory coassembly of block copolymers via an associative driving force in a nonselective solvent, making use of the classical self-consistent field (SCF) theory.

Study of Micellar Behavior of Crown Ether and Tetraethylammonium Bromide in Aqueous Media
Conductivity measurements have been carried out to study the micellar behavior of tetraethylammonium bromide in presence of 15-crown-5 in aqueous media. The measurements were carried out at 298.15 K as a function of surfactant concentration with varying ...

Aerosol-OT surfactant forms stable reverse micelles in aploar solvent in the absence of water [PDF]
Normal micelle aggregates of amphiphilic surfactant in aqueous solvent are formed by a process of entropically driven self-assembly. The self-assembly of reverse micelles from amphiphilic surfactant in non-polar solvent in the presence of water is considered to be an enthalpically driven process.

Voltammetric determination of the critical micellar concentration of surfactants by using a boron doped diamond anode [PDF]
The electrochemistry of three surfactants has been studied by voltammetry at boron doped diamond (BDD) electrode in sodium sulphate solutions. The electrochemical behaviour of these surfactants is characterized by an oxidation signal (peak or wave ...
