The effect of doping transition metal disulfide nanotubes on their structural and electronic properties was studied for the first time using self-consistent band-structure calculations by the density functional tight-binding method (DFTB). The influence of partial Nb → Mo substitution in the walls of MoS2 nanotubes of various diameters and atomic c...

The computer modeling of the eutectic parameters for the Li,NaCa∥F and K,Li,Sr∥F three-component systems is considered. The modeling allows automated computation of the eutectic parameters (temperature and composition) with an accuracy sufficient for scientific and applied purposes. The time consumed for the conventional investigation of the system...

The CaCl2-(NH4)2HPO4-C8H11O7Na-NH3-H2O system was studied at 25°C using the solubility method (Tananaev’s residual concentration method) and pH measurements. The solid phases isolated from the system were characterized using chemical analysis, X-ray powder diffraction, IR spectroscopy, and thermogravimetry. Nanocrystalline carboxymethylcellulose-co...

Layered compounds based on hydrous manganese dioxides (hereafter, Mn-phases) saturated with alkaline-earth cations were synthesized at 3–6°C. These phases are analogues of manganese minerals from oceanic iron-manganese sediments (vernadite, birnessite, buserite-I, an asbolan-like phase, and a hybrid phase). All the Mn-phases, as a rule, had poorly ...

Double complex salts (DCSs) with [M(NH3)5Cl]2+ (M = Rh, Ir, Co, Cr, Ru) cations and [PtBr4]2− anions were prepared in high yields. The salts were two-phase mixtures of the anhydrous and monohydro DCSs. Anhydrous analogues containing [PdBr4]2− anions with M = Cr or Ru were synthesized. All the compounds were characterized using a set of physicochemi...

Nanosized copper-containing particles stabilized on the surface of polymer nanograins were obtained by thermal decomposition of copper-containing precursors in a fluidized bed of ultradispersed polytetrafluoroethylene. Transmission electron microscopy showed that the average size of nanoparticles is 10–12 nm. The structure of the particles was dete...

Porosity and density in water are studied for xerogels prepared by drying iron(III), chromium(III), and zirconium(IV) hydroxide oxide (HO) hydrogels. The hydrogels are either freshly precipitated at pH 7–11 or aged in sodium chloride or sodium sulfate solutions. The space distribution in the xerogels between the volume occupied by the constituent i...
