“…In other words, the inconsistency between M s and the intensity of defect-related PL emission or oxygen vacancies arises from the fact that the surfaces/GBs rather than lattice defects are responsible for high M s . In this context, note the universal behavior of the photoluminescence and of the intrinsic RT ferromagnetic order induced by the surfaces or near-surfaces disordering/defects when comparing the results of nanosized ceria system studied in this work as well as reported by others [e.g 58]. with the one of the most studied oxides, ZnO, in very different forms and preparation conditions, e.g metal ion implanted ZnO crystals[59,60 ], un-doped ZnO nanopowders prepared by hydrothermal rout[61], un-doped ZnO thin films[62], gas ion implanted ZnO single crystals[63], etc.).…”

“…In the recent years, synthesis of magnetic thin films and nanostructures have been investigated for various applications due to their unique structural, electrical, optical and magnetic properties [1][2] [3][4] [5]. The versatile properties and its abundance make iron oxide an interesting material suitable for a wide range of applications [6] [7].…”

Iron oxide films were synthesized by pulsed-DC magnetron sputtering from a metallic target in Ar and O2 gas mixtures. Plasma emission monitoring was implemented to accurately control the metalto-oxygen ratio in the coating through the chemical state of the iron target. The intensity of the Fe* emission line was maintained at a given value (setpoint) in regulating the introduced oxygen flow rate. In addition, the oxidation rate of the growing film was adjusted by controlling the oxidationto-deposition rate ratio as a function of the position of the substrates relative to the magnetron axis.The iron oxide films were characterized by X-ray diffraction, UV-VIS spectrophotometry, electrical measurement and vibrating sample magnetometry. In addition to the crystallization of 2 pure hematite and magnetite phases, both phases coexist in a transition domain for a short range of setpoint depending on the oxidation-to-deposition rate ratio. The electrical, optical and magnetic behaviors of the FeOx films suggest that the relative proportion of phases can be tailored in this range. The FeOx film behaviors can then be tuned from the hematite semi-conductor properties to the semi-metallic magnetite properties.

“…9a. A recent study [38] showed the anticancer activity of TiO 2 nanoparticles against A549 cells, which confirmed that cell viability got decreased only after 72 hrs of treatment. But in the present study, the results illustrated that TiO 2 -ZrO 2 nanoparticles impart cytotoxic effect towards the A549 cell line with 24 hrs treatment.…”

This article reports the synthesis, characteristics and biomedical applications of CeO2-ZrO2 and TiO2-ZrO2 nanoparticles. The nanoparticles are synthesized by Green combustion method. Aloe Vera, dates and pomegranate extracts are used as mediators to avoid toxicity instead of chemical reagents. Hence it is biocompatible, non-toxic and avoiding adverse effect in biomedical applications. The nanoparticles are characterized by XRD to confirm the physical structure. The FTIR, Raman and SEM with EDAX analyses the chemical composition and their morphology. The antibacterial activity of these nanoparticles is assayed by well diffusion method against the bacterial pathogens of Stephylococcusaureus, Shigillaflexneri and Bacillus sp. The anticancer effect of the nanoparticles is investigated on A549 cell line by In Vitro assay. The conceivable purpose is the hydroxyl radicals which are easily produced by oxidizing more hydroxide ions in alkaline solution. Thus the competence of the development is rationally improved at pH is 9.
