Degradation Properties

Nowadays, Mg based metals attract much attention because of their biodegradability and bioactivity. However, over fast degradation rate still restrict their widely medical application. Therefore, surface protection treatment is necessary to control the degradation rate. In this study, a ceramic coating was successfully fabricated on pure magnesium by Micro-arc oxidation (MAO) method. The surface quality was dramatically influenced by deposition parameters such as voltage and frequency. The composition of the sample was characterized by X-ray diffraction (XRD) and the surface morphology was characterized by scanning electron microscope (SEM) equipped with energy dispersive spectroscopy (EDS). The degradation behavior of MAO coated Mg was investigated. It is expected that pure Mg with MAO coating can be used for the orthopedic application especially as bone screw.

Magnesium is potential biodegradable implant materials due to its attractive biological property, degradability and possesses mechanical properties similar to bone. But cast magnesium has an unsatisfactory mechanical property. Microstructure, mechanical properties, and degradation properties of the extruded pure Mg have been investigated by use of optical microscope, tensile testing, and Hank's solution that simulates bodily fluids. Microstructure observation has shown that the extrusion significantly refined the grain size of the cast magnesium, which mainly contributes to the high tensile strength and good elongation. The degradation rate is shown to be significantly reduced by grain refinement produced by extrusion. The results of the present study showed that pure magnesium by extrusion treatment is a simple and promising way of enhancing the mechanical properties and corrosion resistance of pure Mg in Hanks' solution.

AbstractThe electrical reliability properties of PZT (54/46) thin films have been measured for the purpose of integrating this material with silicon-based microelectromechanical systems. Ferroelectric thin films of PZT were prepared by metal organic decomposition. The charge trapping and degradation properties of these thin films were studied through device characteristics such as hysteresis loop, leakage current, fatigue, dielectric constant, capacitancevoltage, and loss factor measurements. Several unique experimental results have been found. Different degradation processes were verified through fatigue (bipolar stress), low and high charge injection (unipolar stress), and high field stressing (unipolar stress).

Effective Use

In material science, green method for synthesis of nanomaterials is feasible, cheaper and eco-friendly protocol. To accomplish this phenomenon, present study was aimed to synthesize Copper oxide nanoparticles using leaf extract of Aloevera with two different precursors CuCl2.2H2O (Cupric chloride) and CuSo4.5H2O (Cupric sulfate). The extraction of Aloevera is employed as reducing and stabilizing agent for this synthesis.Copper oxide Nanoparticles is effective use of biomedical application due to their antibacterial function. The synthesized Copper oxide nanoparticles were characterized by X-Ray Diffraction Spectroscopy (XRD), Energy Dispersive Spectroscopy (EDX), FourierTransform Infrared Spectroscopy (FT- IR) and Scanning Electron Microscope(SEM). XRD studies reveal the crystallographic nature of Copper oxide nanoparticles. Furthermore the Copper oxide nanoparticles have good Antibacterial activity against both gram negative (E.Coli, Klebsiella pneumonia) and gram positive (Bacillus cereus, Staphylococcus aureus)bacteria.
