Surface Activities of a Lipid Analogue Room-Temperature Ionic Liquid and Its Effects on Phospholipid Membrane.
Saheli Mitra,Ranajit Das,Anshu Singh,Mrinmay K. Mukhopadhyay,Gouriprasanna Roy,Sajal K. Ghosh +5 more
TL;DR: The molecule is found to be highly surface active as estimated from area-pressure isotherm of a monolayer of the molecules formed at air-water interface and its surface activities along with the effectiveness in restructuring of a model cellular membrane have been quantified.

Phase diagram study of sodium dodecyl sulfate using dissipative particle dynamics
Monika Choudhary,S. M. Kamil +1 more
TL;DR: This work proposes new models for SDS and demonstrates that they successfully produce a compendious SDS phase diagram, which can precisely overlay the experimental results.
Journal ArticleDOI
Relating the physical properties of aqueous solutions of ionic liquids with their chemical structures
TL;DR: These properties are found to systematically depend on the shape and size of the anion and the cation along with the solution concentration, and the ionic conductivity and viscosity behavior of the solutions do not strictly follow the Walden rule.

Theory of self-assembly of hydrocarbon amphiphiles into micelles and bilayers
TL;DR: In this paper, a simple theory is developed that accounts for many of the observed physical properties of micelles, both globular and rod-like, and of bilayer vesicles composed of ionic or zwitterionic amphiphiles.
