The effect of alkaline earth metals (Magnesium and Calcium) on Hydrogen storage efficiency of alanate nanopowders
Different Aluminum: alkaline earth metal atomic weight ratios effects on structure transformations in alanates nanopowders were studied. Changes in crystal structures from alane to alanates by increasing alkaline earth metals dopants in the mixture with slight changes in crystal structures from rhombohedral centered – trigonal (alane) to trigonal (magnesium alanate), and monoclinic (calcium ala...

متن کاملPromoting alkali and alkaline-earth metals on MgO for enhancing CO2 capture by first-principles calculations.
Developing next-generation solid sorbents to improve the economy of pre- and post-combustion carbon capture processes has been challenging for many researchers. Magnesium oxide (MgO) is a promising sorbent because of its moderate sorption-desorption temperature and low heat of sorption. However, its low sorption capacity and thermal instability need to be improved. Various metal-promoted MgO so...
متن کاملacute toxicity of alkali and alkaline earth metals on rohu, labeo rohita (hamilton) egg and hatchlings
the acute toxicity of salts of alkali and alkaline earth metals, such as sodium (na), potassium (k), calcium (ca) and magnesium (mg) were studied on the egg and larval stages of indian major carp labeo rohita (hamilton). the acute toxicity experiments were conducted followed by the range finding bioassay tests. the experiments were conducted in triplicates. the cumulative percentage of dead or ...
متن کاملFirst-principles solubilities of alkali and alkaline-earth metals in Mg-B alloys
In this article, we present a comprehensive theoretical study of solubilities of alkali Li, Na, K, Rb, Cs and alkaline-earth Be, Ca, Sr, Ba metals in the boron-rich Mg-B system. The study is based on first-principles calculations of solutes formation energies in MgB2, MgB4, MgB7 alloys and subsequent statisticalthermodynamical evaluation of solubilities. The advantage of the approach consists i...
