The drainage and stability of thin liquids foam films from aqueous solutions of the nonionic surfactant hexaethyleneglycol monododecyl ether (C12E6) is studied as a function of surfactant concentration and film size. The thinning rate is investigated in the range of total surfactant concentrations from 10-5 M to 10-4 M, at electrolyte concentration of 0.025 M. The value of the drainage coefficient (α) is determined for each film from its “thickness vs. time” dependence. The film thickness was calculated using microinterferometric method.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
