The clouding behaviour of PEO–PPO based triblock copolymers in aqueous ionic surfactant solutions: A new approach for cloud point measurements
TL;DR: A novel approach for normalising the cloud points to their relative values has been carried out to see the clear effect of ionic surfactant in the presence of copolymer solutions.

Solution Behavior of Poly(n-Isopropylacrylamide) in Water: Effect of Additives
Abstract: The effect of different kinds of additives (electrolytes, nonelectrolytes, hydrotropes, and surfactants) on the cloud point (CP) of low molecular weight and narrow dispersed poly(n-isopropylacrylamide) (PNIPAM) synthesized via reversible addition-fragmentation chain transfer (RAFT) controlled radical polymerization was examined. The CP showed a concentration dependent variation and it is greatly modified in the presence of additives. The size of the random polymer coil at 30°C obtained from dynamic light scattering (DLS) measurements is often influenced by the presence of additives. We have explained the effects of different additives on PNIPAM in terms of their interaction with polymer and resultant changes in the coil structure.

Structural characteristics of the aqueous mixed nonionic–cationic surfactants: Effect of chain length, head group and temperature
TL;DR: In this paper, the micellar structural transition in cationic amphiphiles, viz. alkyltrimethylammonium bromides (C 12 -, C 14-, C 16 - and C 18 TABr), was studied using viscosity and scattering (dynamic light scattering (DLS) and small angle neutron scattering measurements (SANS)).

Micellar Behavior of Polystyrene-Poly(Ethylene Oxide) Diblock Copolymers in Aqueous Media: Effect of Copolymer Composition, Temperature, Salt, and Surfactants
TL;DR: In this paper, the formation and structure of micelles from two amphiphilic polystyrene-block-poly(ethylene oxide) (PS-PEO) diblock copolymers were examined by surface tension, viscosity, steady state fluorescence, dynamic light scattering (DLS), small angle neutron scattering (SANS), and cryo-transmission electron microscopy (cryo-TEM).

Conductometry and Thermodynamics Study of Metal Dodecyl Sulfates in Aqueous Solution
TL;DR: In this article, the aggregation behavior of metal dodecyl sulfates (MDS), [Na1+, Mg2+, Mn2+, Co2+, and Ni2+] in water has been studied by electrical conductivity (at 293.15-333.15 K), critical micelle concentrations (CMCs), degree of counterion dissociation (β), evaluated from conductivity data.
