In this research, Li1.25Mn0.125Ni0.125Co0.5O2 Nano powders, were synthesized using sol-gel method at different temperatures, lithium nitrate, manganese nickel cobalt nitrate as raw materials. Thermal and thermal gravimetric of TGA/DTA, characterization structure properties samples prepared by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) performed. Also, with scheme, i...

Variation in microstructural features of 2024 aluminum alloy plastically deformed by equal channel angular pressing (ECAP) at room temperature, was investigated by X-Ray diffraction in this work. These include dislocation density dislocation characteristic and the cell size of crystalline domains. Dislocations contrast factor was calculated using elastic constants of the alloy such as C 11, C 2...

storage of hydrogen is one of the key challenges in developing hydrogen economy. magnesium hydride (mgh2) is an attractive candidate for solid-state hydrogen storage for on-board applications. in this study, 10 wt.% zrb2 was co-milled with magnesium hydride at different milling times to produce nanocrystalline composite powder. the effect of milling time and additive on the hydrogen desorption ...

It is crucial to find effective solutions environmental contamination that are also ecologically friendly. Zinc oxide (ZnO) well-known as a good photocatalyst. In this work, ZnO microspheres were synthesized using the solvothermal technique. X-ray diffraction (XRD), UV-Vis, and scanning electron microscopy(SEM) used evaluate structural, optical, morphological features of . The hexagonal structu...

Aluminum-based composites reinforced with ceramic particles have been used for many applications because of their high hardness, good wear resistance, low weight, and thermal expansion coefficient. The Al-MgO/Mg composite was prepared in the present study. effects milling time amounts initial Mg MgO were studied on properties composite. milled powder mixtures subsequently analyzed by XRD SEM te...

In this report, ZnO nanoparticles (NPs) was synthesized by chemical method using Zinc Acetate dehydrate [Zn(CH3COO)2.2H2O)] as precursors and Ethanol distilled water solvent. Sodium hydroxide (NaOH) used to maintain the pH helps establish NPs. The NPs are characterized XRD, UV-visible spectroscopy SEM image analysis. XRD characterization gives polycrystalline nature of with size ~23 nm ~27 calc...
