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 ...

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 effects of magnesium stearate, sodium lauryl sulphate (SLS) and talc as lubricants on some powder and tablet properties of silicified microcrystalline cellulose (SMCC) were studied. Single and binary blends of talc, magnesium stearate and SLS at 1% concentration were evaluated as flow modulators on SMCC. Influence of the lubricants on the powder and tablet properties of metronidazole was al...

Magnesium based metal matrix composites (MMCs) have been extensively studied as an attractive choice for automotive and aerospace applications due to their low density and superior specific properties including strength, stiffness and creep resistance. Xi et al [1] studied the Ti6Al-4V particulate (TAp) reinforced magnesium matrix composite which is fabricated by powder metallurgy route. The te...

Magnesium (Mg), present in every cell of all living organisms, is an essential nutrient and primarily responsible for catalytic reaction of over 300 enzymes. The aim of present study was to evaluate the effect of biofield treatment on atomic and physical properties of magnesium powder. Magnesium powder was divided into two parts denoted as control and treatment. Control part was remained as unt...

The intensive production of various biomedical composites made from different biomaterials showed a huge volume of information on properties of composite materials for appropriate research field. The matrix of composite materials is very important but the reinforcement materials known as fillers play an important role for the final properties of biomedical composites like mechanical properties ...

The nitro group in aromatic nitro compounds containing reducible substituents such as methyl, carboxylic acids and phenols, and halogens are selectively and rapidly reduced at room temperature to the corresponding amines in good yield by employing hydrazine glyoxylate in the presence of zinc powder or magnesium powder. It has been observed that hydrazine glyoxylate is more effective than hydraz...

Lamotrigine is a substituted asymmetric triazine. It is a white to pale cream-coloured powder. It is slightly soluble in ethanol and chloroform, and very slightly soluble in water. The pKa of lamotrigine at 25°C is 5.7. Each Lamictal Dispersible/Chewable tablet also contains calcium carbonate, hydroxypropyl cellulose, aluminium magnesium silicate, sodium starch glycollate, povidone, saccharin s...

Here, we report on near-infrared and ATR/FT-IR spectroscopic measurements of magnesium stearate and potato starch powder blends. In the pharmaceutical and food industries, magnesium stearate is commonly used as a supplement in powder blends or granules for the purpose of lubrication and to minimize aggregation and adherence. However, excessive blending of magnesium stearate (MgSt) may lead to u...
