Rare earth metals are used in semiconductors, solar cells and catalysts. This review focuses on the background of oxide metallurgy technologies, the chemical and physical properties of rare earth (RE) metals, the background of oxide metallurgy, the functions of RE metals in steelmaking, and the influences of RE metals on steel microstructures. Future prospects for RE metal applications in steel...

Abstract In 90 Sr analysis, determining its daughter Y improves the sensitivity of radiometric methods. We found that to imprint a cavity made [Y(6-(4-Vinylphenylcarbamoyl)pyridine-2-carboxylate) 3 ] into polystyrene skeleton yields solid phase extraction resin with high selectivity for and Ln(III) over transition metals, alkaline, alkaline-earth cations. used this in an automated chromatograph...

With the increasingly strict environmental protection regulations and improvement of people’s awareness protection, serious pollution caused by soot particles from diesel vehicle exhaust has attracted attention. Catalytic purification technology is one most effective ways to eliminate research development highly catalysts key factors for determining application this technology. In...

In response to the Letter Editor on “Base saturation is an inadequate term for Soil” (), editors of RBCS, Reinaldo Bertola Cantaritti and José Miguel Reichert, would like thank issues raised discussion provided by authors terms “sum bases” “base saturation” . The theoretical fundamentals presented characterize alkali metals (Na K) alkaline earth (Ca Mg), Group 1 2 in [...]

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...

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...

Bond-length distributions have been examined for 55 configurations of alkali-metal ions and 29 configurations of alkaline-earth-metal ions bonded to oxygen, for 4859 coordination polyhedra and 38 594 bond distances (alkali metals), and for 3038 coordination polyhedra and 24 487 bond distances (alkaline-earth metals). Bond lengths generally show a positively skewed Gaussian distribution that ori...

We extend the application of electron capture dissociation (ECD) (which requires at least two charges) to oligosaccharides without basic functionalities by utilizing alkali, alkaline earth, and transition metals (Na+, K+, Ca2+, Ba2+, Mg2+, Mn2+, Co2+, and Zn2+) as charge carriers in electrospray ionization. Both linear and branched oligosaccharides were examined, including maltoheptoase, p-lact...
