Salicylic acid was intercalated into ZnAl-layered double hydroxides lamella as an inorganic host by ion exchange technique. The intercalation compound was examined by X-ray diffraction (XRD), FTIR spectroscopy, differential thermal analysis and thermo gravimetric analysis. Powder X-ray diffractogram shows that the basal spacing of the ZnAl layered double hydroxide with salicylate as the intergallery anion expanded from 8.7 Ǻ to 15.4 Ǻ. The - 3 NO peak located at 1385 cm-1 in FTIR spectra was displaced in the sample with peaks characteristic to the intercalated salicylate. The thermal stability of the intercalated salicylic acid is significantly enhanced compared with the pure form before intercalation.

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.
