The nature of the metal (Mg and/or Fe) salts, used as precursors during the synthesis process of layered double hydroxides, is used as a controlled variable synthesis parameter to obtain iron-containing anionic clay matrices with specific properties. The XRD and N2 adsorption at 77 K analyses indicate that the structural and the textural features of the synthesized clays are influenced by the use of chloride, sulphate or nitrate, as different salts

This work presents a study on an alternative coating method based on biomimetic techniques which are designed to form a crystalline hydroxyapatite layer very similar to the process corresponding to the formation of natural bone. The HA formation on the surface of titanium alloy pretreated with NaOH solution is investigated. Two types of solutions such as supersaturated calcification solution (SCS) and modified SCS (M-SCS) were used to investigate
