In this chapter, compounds of the lanthanide family are introduced, and their discovery, abundance, economic overview, and important chemical properties will be reviewed briefly. An interesting fact about the lanthanide family is that the elements are not as rare as their names might imply. Lant...

Calculations based on the density functional theory have achieved considerable reliability for the prediction of the properties of materials. In the present work, we have obtained enthalpies of formation of binary intermetallic compounds of boron with the rare-earth elements. These values have b...

A holmium boride HoB50 polycrystalline sample was synthesised by boron-thermal reduction from the elements at high temperature. The temperature dependencies of the heat capacity Ср(Т) and the unit cell parameters a(T), b(T), c(T) of holmium boride were determined experimentally in the tempera...

The specific heat, thermal expansion and magnetic properties of polycrystalline sample of nonstoichiometric dysprosium boride DyB50, that was synthesized by boron-thermal reduction of the metal from its oxide in vacuum, were studied at 2–300 K. The measurements revealed a heat capacity and magn...

The effect of oils and hardness on stability of foams made from solutions containing 0.01 wt% of three EO alcohol ethoxysulfate sodium salt of commercial anionic surfactant Neodol 25-3S was investigated. When dissolved calcium was present under alkaline conditions using Na2CO3 instead of NaOH as...

Steels with good machinability are required for the ever-increasing demand for machining efficiency in industry. The manganese sulfide (MnS) inclusions in lead-free resulfurized free-cutting steels act as stress raisers, lowering the shear strength of steel such that the cutting resistance is re...

A hybrid ion exchanger (HIX) containing manganese(IV) oxide based on a macroporous, strongly basic anion exchanger as supporting material was obtained. The introduced MnO2 (26.4% Mn) was amorphous and evenly distributed within the polymer matrix. The hybrid material was used for removal of sulfi...

Manganese corrole complexes catalyze the efficient oxidation of organic sulfides to sulfoxides with iodobenzene diacetate [PhI(OAc)2] as a mild oxygen source in the presence of small amounts of water. Various substituted thioanisoles can be efficiently oxidized to sulfoxides with quantitative co...

This study aims to investigate the durability and microstructure of cement-sodium silicate grouts with high water to binder ratios (w/b) of 1.1–2.5 upon exposure to sea water. Grout specimens were prepared by mixing ordinary Portland cement paste and 4.4–7.5 wt% sodium silicate (water glass so...

Flotation tests were performed on a skarn ore to attain the selective separation of scheelite (CaWO4) from fluorite, apatite, and silicates. Fluorite and apatite constitute common gangue minerals in scheelite ores. Due to their similar surface properties and good floatability, the separation of ...

Molecular dynamics was utilized to investigate ionic structure, dynamics and adsorption behaviors of the sulfate and sodium ions highly solvated in the nanometer channel of calcium silicate hydrate (C–S–H) with two different Ca/Si ratios. Due to H-bond connection from silicate oxygen sites and...
