AB  - The protective abilities of composite coatings based on electrochemically and chemically formed polyaniline powder against the corrosion of mild steel were investigated. A polyaniline powder has been prepared in the form of an emeraldine base and benzoate salt through chemical dedoping and doping. The composite coatings using polyaniline powders, which were obtained through different routes, and base coatings, which were not corrosion-resistant, with different formulations were prepared and applied on mild steelsamples. The corrosion was investigated using an electrochemical impedance technique in 3% NaCl, andthe atmospheric corrosion was assessed in a humidity chamber. Emeraldine-benzoate salts, which area chemically synthesized polyaniline, offer the best protection with an optimal polyaniline concentration of approximately 5 wt%. The different corrosion behaviors were assessed relative to the presence of aniline oligomers in the samples after characterization using UV-vis spectrophotometry. Upon comparison between the corrosion behavior in 3% NaCl with commercial primer paint for iron and that with apaint containing 5 wt% PANI, the composite coating has superior anticorrosion characteristics. The mech-anism for the protection of mild steel from corrosion through composite polyaniline coatings was also considered. © 2014 Elsevier B.V. All rights reserved.

AB  - Multifunctional drug delivery system based on hydroxyapatite may be a research challenge in the treatment and reconstruction of bone tissue. Vitamin D3 has a positive effect on osteogenesis as it increases osteoblast differentiation and mineralization of bone tissue. The purpose of the study presented in this paper has been to examine the possibility of the synthesis of a new multifunctional nanoparticulate system for local delivery of vitamin D3 suitable for applications in bone engineering. The synthesis, characterization and application of three nano particle systems was shown: hydroxyapatite, hydroxyapatite/vitamin D3 and hydroxyapatite/PLGA/vitamin D3. The obtained vitamin D3-loaded nanoparticles based on hydroxyapatite. Characterization was performed with wide-angle X-ray structural analysis (XRD), infrared spectroscopy (FT-IR), field-emission scanning electron microscopy (FESEM), zeta potential (ZP) and particle sized distribution (PSD) methods. Basic in vitro studies were performed implantation of materials in rats. XRD and FT-IR analyses confirmed that the vitamin D3 is loaded hydroxyapatite and PLGA. Different values of zeta potential may refer to different phenomenological processes during in vivo studies.
