Micellization of cetyltrimethylammonium bromide: effect of small chain Bola electrolytes.
Animesh Pan,Pallabi Sil,Sounak Dutta,Prasanta Kumar Das,Subhash Chandra Bhattacharya,Animesh Kumar Rakshit,Vinod K. Aswal,Satya P. Moulik +7 more
TL;DR: NMR study as well supported the non-mixing of bolas with the CTAB micelles, which interacted in solution like "amphiphilic electrolytes" to influence the surface and micelle forming properties of C TAB.

Small-angle X-ray scattering from micellar solutions of gemini surfactants
Vinod K. Aswal,Prem S. Goyal,Susmita De,Santanu Bhattacharya,Heinz Amenitsch,Sigrid Bernstorff +5 more
TL;DR: In this paper, the results of small-angle X-ray scattering (SAXS) experiments on the above system for spacer lengths of m=3, 4 and 12 were reported.

Structure and interaction in the polymer-dependent reentrant phase behavior of a charged nanoparticle solution.
TL;DR: The SANS data in polymer contrast-matched conditions have been modeled by a two-Yukawa potential accounting for both repulsive and attractive parts of total interaction potential between nanoparticles and both of these interactions are found to be long range.
Microstructure of copolymeric micelles modulated by ionic liquids: investigating the role of the anion and cation
Sadafara A. Pillai,Chin-Fen Lee,Debes Ray,Vinod K. Aswal,Haridas Pal,Li-Jen Chen,Pratap Bahadur +6 more
TL;DR: In this article, the influence of ionic liquids (ILs) on the physicochemical properties of an ethylene oxide-propylene oxide (EO-PO) star shaped block copolymer, Tetronic®1304, by employing cloud point (CP), viscosity, dynamic light scattering (DLS), small-angle neutron scattering (SANS), high sensitivity differential scanning calorimetry (HSDSC) and fluorescence measurements and 1H NMR spectroscopy.

Fluorescent complex coacervates of agar and in situ formed zein nanoparticles: Role of electrostatic forces.
TL;DR: Systematic decrease in storage modulus with ionic strength implied screened Coulomb interaction was responsible for the observed coacervation of zein nanoparticle with biopolymers, and polysaccharides in particular.
