Influence of chain charge and complexation on the overlap and entanglements formation in poly(acrylic acid) salt-containing aqueous solutions
Article Abstract:
Light scattering and viscometry methods are used for studying dilute-semidilute regime crossover in aqueous solutions of partly neutralized poly(acrylic acid) and of its complex with tetradecyltrimethylammonium bromide. The results have shown that in semidilute entangled solutions the surfactant has acted as an effective structuring agent due to the binding of polyelectrolyte chains via surfactant micelles.

Fabrication of symmetric hierarchical hollow PbS microcrystals via a facile solvothermal process
Article Abstract:
Symmetric hierarchical hollow PbS structures consisting of nanowalls are successfully fabricated by a facile solvothermal process in ethylenediamine, employing lead acetate trihydrate and dithizone as precursors. The results have shown that the temperatures, solvent and sulfur sources play vital role on the morphologies and sizes of the symmetric hierarchical hollow PbS microcrystals.

Self-assembly synthesis of single-crystalline tin oxide nanostructures by a poly(acrylic acid)-assisted solvothermal process
Article Abstract:
Single-crystalline Sn[O.sub.2] nanocones in root size and their self-assembly morphologies are obtained through a solvothermal process in the presence of poly(acrylic acid). The as-synthesized Sn[O.sub.2] nanocones with the typical rutile phase has displayed preferential growth along the [001] direction and high chemical stability.
