This research investigates the influence of certain vitamins (A and D2) on the possibility of hydroxyapatite formation on polymer surfaces. A coating method based on biomimetic techniques was used to form a crystalline hydroxyapatite thin layer on porous polyurethane matrix. The method is based on a wet process of hydroxyapatite formation that involves porous polyurethane film soaking in a modified synthetic Simulated Body Fluid (SBF) solution. This

This work presents a study on the possibility of obtaining hydroxyapatite thin layers on porous polyurethane support using a modified coating method, which is based on a biomimetic technique. To investigate bone-like apatite coatings formation on polyurethane surface, two types of solutions such as supersaturated calcification solution (SCS) and modified SCS (M-SCS) were used. The modified supersaturated calcification solution was prepared with added

A chemical method for the production of thin ZnO films by using a chemical precipitation technique is presented in this paper. The method consists in obtaining the thin ZnO films (300-500 nm) by thermal decomposition of zinc hydroxide formed by the precipitating of zinc acetate from alkaline solution, in the presence of ethylenediamine on a solid support i.e. glass. The use of this method implies investment economies, and the simplicity of the work

Gentamicin–hydrotalcite-like anionic clays nanocomposites were synthesized by using the direct co-precipitation method. XRD, XPS and FTIR analysis reveal that for the hydrotalcite-like sample, the drug is adsorbed only on the anionic clay surface, whereas for copper, partially substituted hydrotalcite gentamicin is detected also in the clay interlayer. The affinity of gentamicin to form complexes with some transition metals such as iron and copper

Polymer–zeolite nanocomposite membrane separations represent a growing technological area with potentially high economic reward due to the low energy requirements. The use of polymer–zeolite nanocomposite membrane with incorporated zeolite nanocrystals has the potential to combine the advantages of polymers and zeolites while overcoming the shortcomings of both materials. This work focuses on the use of zeolite SAPO-5 nanocrystals for the preparation
