The densities of dodecyltrimethylammonium bromide in pure water and in methanol + water mixed solvent media containing (0.10, 0.20, 0.30, and 0.40) volume fractions of methanol were measured at (298.15, 308.15, 318.15, and 323.15) K. The concentrations are varied from (0.4 ×10-1 to 1.2 ×10-1) mol kg-1. The results showed almost increase on the densities with increasing surfactant concentration. Also, the densities are found to decrease with increasing temperature over the entire concentration range investigated in a given mixed solvent medium and these values are found to decrease with increasing methanol content in the solvent composition. The effects of concentration, solvent composition and temperature on the partial molar volumes are discussed.

“…A survey of the literature indicated that the influences of polyelectrolyte concentration, polyelectrolyte molecular weight, medium, and temperature on counterion condensation in salt-free polyelectrolyte solution have been fairly investigated [7][8][9][10][11][12][13][14][15][16][17][18].…”

In order to understand how live matter functions one needs to understand the interaction between polyelectrolytes. We discover a general dependence of polyelectrolyte conductivity valid in at least nine decades of polyelectrolyte concentration spanning dilute and semidilute pure water solutions. Furthermore, we showed that current state of the art theories can not explain polyelectrolyte conductivity and suggest the path in transport theories which needs to be taken in order to explain polyelectrolyte conductivity.
