In the present study, magnesium oxide (MgO) and chloride (MgCl) nanoparticles were phytosynthesized. Selected parameters like leaf extracts from Moringa oleifera, Vernonia amygadalina Occimum gratissimum, time of reaction, precursor salts at varying concentrations, plant to volume ratio, pH medium light sources optimized for a better production nanoparticles. The phytosynthesized MgO MgCl chara...

Since metals are cable of catalysing the free radical reactions, different metal (Mg, Mn, Zn) compounds were studied to determine their hydroxyl radical generating and/or scavenging abilities depending on ligand in a H2O2/OH -luminol system with or without microperoxidase. Magnesium oxide, magnesium gluconate and manganese gluconate increase the free radical reactions in the H2O2/OH -luminol sy...

There are more than 230 boron minerals which contain different amounts of boron oxide (B2O3) percentages. Magnesium borates are one of the boron mineral groups that have important properties of high elasticity coefficient, resistance to corrosion and high heat resistance. In this study, magnesium borate production is studied by hydrothermal synthesis method from a sodium borate mineral of tinca...

A new protocol for synthesizing different functionalized isoxazoles is provided. Carbamoylnitrile oxide generated from nitroisoxazolone underwent inverse electron-demand 1,3-dipolar cycloaddition with 1,3-dicarbonyl compounds in the presence of magnesium acetate that formed magnesium enolate in situ. Although electron-deficient trifluoroacetoacetate did not undergo this cycloaddition under the ...

An increase in magnesium intake has been suggested to lower blood pressure (BP). However, the results of clinical studies are inconsistent. We studied the effects of magnesium supplementation on office, home, and ambulatory BPs in patients with essential hypertension. Sixty untreated or treated patients (34 men and 26 women, aged 33 to 74 years) with office BP >140/90 mm Hg were assigned to an ...

In this experimental work, Manganese oxide (MnO2), Zinc oxide (ZnO), Iron oxide (Fe2O3) and Magnesium chloride (MgCl2) were used as activating flux to investigate the effects for SS 304 in tungsten inert gas (TIG) welding. Ultimate tensile strength, percentage elongation, Penetration depth and width were studied of material SS 304. The experimental results indicated that the MnO2 and Fe2O3 flux...

magnesium alloys in liquid-phase condition form surface oxide films due to their high rate of oxidation. oxide films enter the melt as a result of surface turbulence, and remain inside the workpiece after solidification. the incoherent nature of their interface causes decreases in mechanical properties and reliability of castings. the effect of critical velocity and greater velocities of enteri...
