A mixture of 10 wt% CuO-10 wt% FE2O3 supported on cordierite were prepared by wet impregnation. The as-prepared solids doped with Li2O (0. 75-3 mol %) were calcined at 500-900 º C. The crystalline phase, morphology, and surface area were investigated by XRD, HR-TEM and N2-adsoprtion-desorption. Moreover, their photocatalytic activities of samples calcined at 700° C on the degradation of phenol were evaluated under UV-irradiation. The catalytic activity of different solids toward H2O2 decomposition was studied. Nano-materials were used to adsorb dyes as Remazole-Red and Congo-Red from aqueous solution. The sorption process was in good agreement of pseudo-second order equation and the Langmuir equation through their adsorption kinetics and isotherms, respectively. The CuO-FE2O3/ cordierite doped with 0. 75% Li2O at 700 º C adsorbent was found to possess the highest removal efficiency of Remazole-Red and/or Congo-Red dyes and potentially lowering capital and operational costs for \practical applications. The highest removal efficiency of the anionic dyes over 0. 75% Li2O at 700 º C can be discussed by observing the appearance of new active phases as CuO, CuFe2O4 and LiCuO, decreasing the crystallite size of these active phases. 0. 75 mol% Li2O has the greatest activity in H2O2 decomposition reached 700 %. This result may be related to the lowest particle size and the highest surface area of this sample, which also produced a large number of electrons donating active sites for H2O2 decomposition.

This review discusses recent developments in the field of nanosized biomaterials and their use in tissue regeneration approaches. The aim is to provide an overview of the research focused on nanoparticle-based strategies to stimulate regeneration. In particular, nanoparticles improve the regenerative capabilities of biomaterials offering ways to control surface and mechanical properties. Moreover, incorporation of nanoparticles within biomaterials increases cellular adhesion, differentiation and integration of stem cells into the surrounding environment. Finally, the drug delivery capabilities of nanoparticles offer additional possibilities to increase the biological performance of biomaterials. As the development of nanoparticles continues, incorporation of this technology in the field of regenerative medicine will ultimately lead to new tools that can diagnose, track and stimulate the growth of new tissues and organs.

The photodegradation of Ponceau-S dye was investigated using UV radiation in presence of nanosized FE2O3.Removal efficiency of Ponceau-S was sensitive to the operational parameters such as dye concentration, catalyst dose, pH, contact time, TOC and COD. The photocatalytic treatment of red colored Ponceau-S dye by magnetic nano semiconductor (FE2O3) is an effective, economic and faster mode. The kinetics and isotherm studies were carried out. A simple kinetics model was proposed which confirmed pseudo second order reaction. Langmuir isotherm fitted this study. The optimum conditions for the degradation of the dye were initial concentration 50 mgL-1, pH 8, contact time 20 minutes and catalyst dose 5 gL-1 of FE2O3.The semiconductor photocatalyst was also carried out for SEM and XRD analysis which confirms the utilized semiconductor was nanosized.

One of the main problems of surface and underground water hazardous concentrations of heavy metals into the precious resources that are. The method this type of filtration to remove contaminants such that is used to capture the mentioned surface. In adsorption sorbent surface area and volume due to the high porosity is able to absorb pollutants and water to separate into their cavities. Because the surface area and volume of porous iron particles having a substantial ability to absorb pollutants from the water able to be. The ability of nano particles a-FE2O3Fe3O4, and  g-FE2O3 ion in the adsorption of heavy metals such as Cr6+, Cu2+, Cd2+ and Ni2+studied and compared.

In this study, the effect of FE2O3 particle concentration on the protective properties of the Ni-FE2O3 composite coating formed on AISI304 substrate was evaluated. The electrodeposition process was conducted in a plating bath without and with different concentration of FE2O3 particles. The surface morphology and structure was characterized using scanning electron microscope (SEM), Electronic diffraction line scans (EDS) and X-ray diffraction (XRD). The corrosion behavior of the coating was evaluated by measuring the variation of corrosion potential during the immersion time and electrochemical impedance spectroscopy (EIS) method. The results revealed that in pH=4 and a current density of 20 mA/cm2, The precipitation of FE2O3 particles in nickel matrix reached to its maximum value when the concentration of the particles in the electrolyte was 20 g/lit. However, the microhardness results and corrosion behavior of coated samples was revealed that the homogeneous dispersion of second phase particles in matrix plays a dominant role in the promotion of surface and protective properties of the coating. Nickel coating increased the corrosion resistance of AISI304 more than double. The addition of FE2O3 particles into the electroplating bath caused an increase in corrosion resistance of Nickel coating and the coating fabricated in the bath containing 15g/lit FE2O3 provided the highest corrosion resistant which was almost 5 times higher than corrosion resistance of the steel substrate.

In this paper we describe a facile method for the synthesis of Cu2O nanoparticles by reduction of Fehling's solution, using glucose as reducing agent. Copper sulfate is used as a precursor with potassium sodium tartarate in an alkaline media to produce Fehling's solution. The precipitation of Cu2O nanoparticles from this solution in the presence of glucose was controlled by addition of SLES or Triton-X 100 as surfactants. The reactions have been carried out at 60°C with high repeatability. The purification process of the Cu2O product does not require expensive methods, since a solid product is obtained from a reaction in liquid phase. The resulting Cu2O nanoparticles were characterized by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy-Dispersive X-ray spectroscopy (EDX), Transmission Electron Microscopy (TEM) and Fourier-transform infrared (FTIR) spectroscopy.
