A conformation study of polyelectrolyte-dendritic surfactant complexes in dilute solutions

Conformation and order in polyelectrolyte solutions

2014 The scattering factor of polyelectrolyte solutions in the absence of added salt presents a peak at a scattering vector qm which varies like C 1/2. This has been sometimes interpreted in terms of a local orientational order of cylinders. The variation holds however through many concentration regimes, and other explanations in term of correlation holes have been proposed. We evaluate the dif...

Simulation of Dilute Polymer and Polyelectrolyte Solutions: Concentration Effects

a study of baudrillards ideas in brian moores fiction

پیدایش مرحله ی جدیدی از نظام سرمایه داری بعد از جنگ جهانی دوم همزمان است با ظهور عصر اطلاعات و رسانه جمعی. در چنین جامعه ای سیر آزادانه ی نشانه ها در فضای بی اساس مجازی بر سرعت فرسایش واقعیت می افزاید. به اعتقاد بودریار، فقدان واقعیت به واسطه ی شبیه سازی آن و تولید حاد واقعیت (hyperreality) پنهان خواهد ماند. این پژوهش بر آن است که جامعه فرانوین توصیف شده در سه رمان بریان مور را با توجه به نظر...

Phase behavior of polyelectrolyte-surfactant complexes at planar surfaces.

We investigate theoretically the phase diagram of an insoluble charged surfactant monolayer in contact with a semidilute polyelectrolyte solution (of opposite charge). The polyelectrolytes are assumed to have long-range and attractive (electrostatic) interaction with the surfactant molecules. In addition, we introduce a short-range (chemical) interaction which is either attractive or repulsive....

Vesicles and onion phases in dilute surfactant solutions

We study theoretically the stability of phases of unilamellar and multilamellar vesicles in bilayer-forming surfactant solutions. It is argued that these are likely to arise, instead of a bicontinuous "sponge" phase, when the elastic constants of the bilayer are chosen so that the curvature energy of a sphere is small. At very low volume fractions we predict a phase of noninteracting vesicles; ...
