Morphology, particle size distribution, and composition in one- and two-salt metal oxinate liesegang patterns

Article Abstract:

Investigating the various aspects of the pattern formation, spanning the morphology of the bands, the patterning schemes in two-precipitate systems, and mainly the particle size distribution (PSD) and its variation with initial supersaturation and the time evolution of the pattern is presented. In cobalt oxinate liesegang patterns with the same initial concentration difference, the average particle size increases while the number of bands and the number of particles (within a given band) decrease as the initial supersaturation increases.

Structure of proton-conducting anhydrous gel electrolytes based on poly(glycidyl methacrylate)

Article Abstract:

A study of phosphoric acid-solvent-methacrylate-based polymer gel electrolytes is reported that have ionic conductivities above 5 x 10(super -4) S.cm(super -1) at ambient temperature. The objective is to understand better the interaction of orthophosphoric acid with the solvent and the polymer gel to gain information on possible proton-conduction mechanisms.

Simulation of Liesegang patterns: effect of reversible complex formation of precipitate

Article Abstract:

Formation of ID Liesegang patterns is investigated numerically by assuming precipitation and reversible complex formation. The numerical simulations show that the correlation between the position of the first and last bands is strongly linear.
