Magnesium Sulfate-doped L-Leucinium oxalate (MSLO) single crystal was grown using slow evaporation method. Structure of the determined by single-crystal X-Ray Diffraction (XRD). Lattice parameters MSLO were determined. Optical transmittance study done to find various linear optical like band gap, reflectance, refractive index, absorption coefficient, extinction conductivity. Vickers Micro hardn...

Objective(s): So far, extensive research has been conducted on the preparation and characterization of nano ceramics based on Ca-Si by sol- gel method and bioactivity was evaluated, but, a few researches have paid attention to the preparation of materials by mechanical activation (MA). The aim of this study was the preparation of akermanite nano powder by mechanical activ...

Natural Akermanite (NAM) has been successfully prepared by a modified sol-gel method. Optimization in calcination temperature and mechanical ball milling resulted in a pure and nano-sized powder which characterized by means of scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM) and Fourier transform infrared Spectroscopy (FT–IR). Calcium nitrate, ...

Recently, magnesium and its alloys have attracted great attention for use as biomaterial due to their good mechanical properties and biodegradability in the bio environment. In the present work, nanocomposites of Mg - 5Zn - 0.3Ca/ nHA were prepared using a powder metallurgy method. The powder of Mg, Zn and Ca were firstly blended, then four different mixtures of powders were prepared by adding ...

A new mucoadhesive tablet, which releases natural active agents for pain reduction and rapid healing of canker sores, has been prepared and characterized. Adhesive tablets were prepared by compression molding of mixed powders of crosslinked polyacrylic acid and hydroxypropyl cellulose, absorbed with citrus oil and magnesium salt. The rate of tablet erosion and the rates of citrus oil and magnes...

Magnesium is considered one of the most promising materials for reversible hydrogen storage, because it has high storage capacity. However, the high thermodynamic stability of magnesium hydride is unfavorable for dehydrogenation processes. Understanding the bonding nature of Mg and H is essential for improving its dehydrogenation performance. Therefore, the charge density distribution in MgH2 w...

Attempts to synthesize solvent-free MgB12H12 by heating various solvated forms (H2O, NH3, and CH3OH) of the salt failed because of the competition between desolvation and dehydrogenation. This competition has been studied by thermogravimetric analysis (TGA) and temperature-programmed desorption (TPD). Products were characterized by IR, solution- and solid-state NMR spectroscopy, elemental analy...

Magnesium and its alloys are among the important research topics in terms of low density, large damping capacity, recyclability, dimensional stability. The contact with oxygen easily causes formation oxide. In this study, metal purchased powder form was grinded by mechanical milling method for various hours. effect times on Mg/MgO composite investigated. Scanning electron microscope (SEM) image...

Milk is an important food; it supplies our body with the essential mineral’s requirements. In this study, some major (Calcium, magnesium, phosphorus) and minor (copper, iron, zinc) minerals were determined in seventy-eight random processed milk samples. These samples collected from different markets Benghazi city, Libya during 2017. The order of elements concentrations all was calcium> phosp...
