The present review highlights the different types of nano ferrites and their surface modified composites as an alternative adsorbent in waste water treatment. In this review, the recent progresses and potential applications of SFNPs/SFNCs for the removal of organic and inorganic contaminants through adsorption routes are critically reviewed. There are number of water purification techniques but the adsorption is one of the simplest, effective and economical method for wastewater purification. Adsorption isotherm models, kinetic models, thermodynamic parameters and adsorption mechanism have also been discussed. The present article lists different type of adsorbents and reviews state-of-the-art of the removal of different pollutants from water. The efforts have been made to discuss the sources of contamination and toxicities of pollutants. The possible techniques of recovery and reuse, toxicity, research gaps and the future perspective of SFNPs are also discussed in brief. Based on this review, it is possible to conclude that SFNPs and their derivative composites have unlimited capacity in addressing array of problems encountered in water and wastewater treatment. The present study highlights the future areas of research for waste water treatment.

Hydroxyapatite (Ca10(PO4)6(OH)2, HAp), carbonated HAp and titanium oxide are of interest for bone-interfacing implant applications, because of their demonstrated osteoconductive properties. They were coated on the titanium implants and investigated the in vitro and in vivo performance. HAp coatings were performed by the thermal substrate method in aqueous solutions. Titanium oxide film was also formed on the titanium implants by gaseous oxidation, or by anodizing in the acidic solution. All the specimens covered with HAp, carbonated HAp or TiO2 (rutile or anatase). were characterized by XRD, EDX, FT-IR and SEM. In the in vitro testing, the mouse osteoblast-like cells (MC3T3-E1) were cultured on the coated and non-coated specimens for up to 30 days. Moreover, the osseointegration was evaluated from the rod specimens implanted in rats femoral for up to 8 weeks. In in vivo evaluations two weeks postimplantation, new bone formed on the coated and non-coated titanium rods in the cancellous bone and cortical bone, respectively. Bone-implant contact ratio, in order to evaluate of new bone formation, was significantly depended on the compound formed on the titanium implant.
