Extraction of Palladium(II), Platinum(II), and Platinum(IV) by Bisacylated Diethylenetriamine from Hydrochloric Acid Solutions
Russian Journal of Inorganic Chemistry - Tập 53 - Trang 462-469 - 2014
The extraction properties of bisacylated diethylenetriamine are studied in the extraction of palladium(II), platinum(II), and platinum(IV) from hydrochloric acid solutions. Optimum extraction parameters are determined. The extraction of metal ions at these parameters follows an ion-associative mechanism. The concentration constants and thermodynamic parameters of extraction reactions are calculate...... hiện toàn bộ
Effect of Dopants on the Functional Properties of Lithium-Rich Cathode Materials for Lithium-Ion Batteries
Russian Journal of Inorganic Chemistry - Tập 66 - Trang 777-788 - 2021
A comparative study was made of the effect of the dopant nature on the electrochemical performance of lithium-rich oxides of the general composition 0.5Li2MnO3⋅0.5LiMn0.33Ni0.33Co0.31M0.02O2 (M = Mg, Cr, Zr). The obtained materials were tested as cathodes in CR2032 coin-type cells versus lithium metal. The results of the study attested to the fact that the main role in the degradation of the mater...... hiện toàn bộ
Classification system for fullerenes
Russian Journal of Inorganic Chemistry - Tập 53 - Trang 1384-1395 - 2008
The universal classification of nanoshells developed on the basis of group theory makes it possible to formulate new rules of the composition and structure of fullerenes. The classification shows the possible numbers of atoms for a given point group of symmetry, their arrangement at the symmetry elements, the number of nonequivalent groups of atoms in a structure, their coordination numbers, and t...... hiện toàn bộ
Structures of monomeric octahedral d 2 rhenium(V) oxo complexes with oxygen atoms trans to the oxo ligands: Complexes with ethoxo ligands trans to O(oxo)
Russian Journal of Inorganic Chemistry - Tập 59 - Trang 1715-1726 - 2014
Specific features of the structure of mononuclear octahedral rhenium(V) complexes with oxygen atoms of ethoxo ligands trans to the multiply bonded oxo ligands have been considered. The complexes contain inorganic or organic monodentate ligands, as well as organic bi-, tri-, and tetradentate ligands in the equatorial plane. It has been noted that the Re-O(OEt)

Mutual solubility between hexane and tri-n-butyl phosphate solvates of lanthanide(III) and thorium(IV) nitrates at various temperatures
Russian Journal of Inorganic Chemistry - Tập 52 - Trang 1144-1146 - 2007
The phase diagrams of binary liquid systems consisting of hexane and a tri-n-butyl phosphate (TBP) solvate of an Ln(III) (Ln = Nd, Gd, Y, Yb, Lu) or Th(IV) nitrate at various temperatures are considered. The diagrams show a field of homogeneous solutions and a two-phase field in which phase I is hexane-rich and phase II is rich in [Ln(NO3)3(TBP)3] or [Th(NO3)4(TBP)2]. The miscibility gap in the bi...... hiện toàn bộ

Sol–gel synthesis of iron yttrium garnet Y3Fe5O12 using metal acetylacetonates
Russian Journal of Inorganic Chemistry - Tập 62 - Trang 1135-1140 - 2017
The synthesis of hydrolytically active heteroligand complexes of the composition [M(O2C5H7)x(iOC5H11)y] (M = Fe3+ and Y3+) using iron and yttrium acetylacetonates was studied. Their reactivity was shown to be dependent on the degree of shielding of iron and yttrium cations in hydrolysis and polycondensation during the formation of a connected dispersion system. The crystallization temperature of i...... hiện toàn bộ
