КАРБИД ТИТАНА -- НАНОКРИСТАЛЛЫ -- ЭЛЕКТРОННАЯ СТРУКТУРА
Аннотация: The electronic band structure and stability of extended nanocrystallites (NCs) of titanium monocarbide TiC were investigated by the electron density functional–tight binding (DFTB) technique. The stability of prismatic NCs increases with the number of atomic layers; the electronic spectrum of these compounds changes from semiconductor (for NC of minimal atomic size) to metallike type inherent in crystalline titanium carbide

КАРБИДЫ БИНАРНЫЕ -- КВАНТОВО-ХИМИЧЕСКИЕ ИССЛЕДОВАНИЯ
Аннотация: This paper reviews the results of electronic structure studies and investigations of the nature of chemical bonding and properties of binary d-metal carbides in the crystalline and molecular states. X-ray emission and X-ray photoelectron spectroscopy as well as quantum-chemical data are analyzed, and variations of the electronic properties and interatomic interactions are discussed for carbides of high-melting metals doped on the metal sublattice and a series of their reciprocal solid solutions: NbC–TaC, TiC–VC0.87, TiC–NbC, and NbC–MoC0.67 over a wide range of compositions. Prospects are discussed for application of quantum-chemical methods to structure and property modeling and forecasting for a new class of molecular clusters — binary metallocarbohedrenes M8−nMn ′C12 and related metal–carbon nanoparticles of “mixed” composition

МОЛИБДАТ ГАДОЛИНИЯ -- ДОМЕНЫ
Аннотация: Barkhausen pulses generated in stepped motion of a single plane domain boundary ~PDB! are investigated experimentally in single-crystalline wafers of the extrinsic ferroelastic ferroelectric gadolinium molybdate containing artificial pinning centers of the ‘‘field inhomogeneity’’ type near the edges of the sample. Two scenarios of the evolution of a PDB in interaction with ‘‘defects’’ are proposed on the basis of analyzing the shape of the pulses in a linearly increasing field: small changes of the pulse shape in a weak field and the generation of wedge domains in a strong field. The proposed mechanism of PDB motion due to the generation of steps near the edge of the sample and their longitudinal motion provides a means for explaining the experimentally observed linear field dependence of the PDB velocity and for determining the velocity of the steps

АЛМАЗОПОДОБНЫЕ КРИСТАЛЛЫ -- ФУЛЛЕРЕНЫ
Аннотация: Novel dense crystalline modifications of small Cn fullerenes (n= 28, 40), i.e., the so-called autointercalated hyperdiamonds with combined covalent and van der Waals types of Cn–Cn interatomic bonds, are proposed and simulated. The crystal structures of these modifications consist of Cn fullerene molecules forming diamond lattices in which holes are occupied by the same fullerene molecules. The crystal structures, elastic and electronic properties, and energies of formation of the Cn autointercalated hyperdiamonds are calculated using the ensity-functional-based tight-binding (DFTB) method. The bulk moduli of the autointercalated hyperdiamonds are found to increase abruptly as compared to those of the initial hyperdiamonds. It is established that the C28 and C40 autointercalated hyperdiamonds are semiconductors with the band gaps approximately equal to 1.30 and 0.94 eV, respectively

Аннотация: The crystal structure of thin lead sulfide (PbS) films fabricated by hydrochemical deposition is studied by X ray diffraction analysis. It is established that both the synthesized PbS films and the same films annealed in the temperature interval of 293–423 K have a cubic (space group Fm m) crystal structure different from the B1 type structure. In this structure, sulfur (S) atoms are located not only in positions 4(b) (octahedral interstices of the face centered sublattice of lead (Pb) atoms) but also in positions 8(c), i.e., in tetrahedral interstices. The occupations of positions 4(b) and 8(c) by S atoms are ~0.84 and ~0.08, respectively. Long range order in the location of S atoms in positions of each type is absent, but correlations may be present. The new revealed structure of PbS films remains stable under a prolonged annealing in the temperature interval from 293 to 423 K

Аннотация: Precipitation of crystalline ZrC in the surface region of dilute ZrC–NbC solid solutions (<1.0 mol % ZrC) was revealed by electron microscopy, x-ray microanalysis, laser mass spectrometry, and x-ray diffraction. The ZrC precipitation was shown to be a consequence of the diffusional decomposition of the dilute Zr1 – xNbxC solid solutions. The boundaries of the solid-miscibility gap in the ZrCy–NbCy system were calculated. The segregation energy of zirconium carbide was estimated at –33.3 kJ/mol

Аннотация: The electronic structure and bonding configuration of cubic (B1 type) Zr- and N-deficient zirconium nitride phases were investigated using self-consistent linearized muffin-tin-orbital calculations in the atomic-sphere approximation for a supercell containing eight atoms. Interatomic interactions were analyzed in terms of the crystalline orbital overlap population calculated by the semiempirical tight-binding method. The results are compared with earlier calculations and available experimental data on the electronic structure of nonstoichiometric ZrN

Аннотация: The band structure of new layered (AlB2 type) Ca(AlxSi1 – x)2 and Sr(GaxSi1 – x)2 superconductors is studied by the first-principle full-potential LMTO method. It has been shown that the superconducting properties of ternary silicides are due to the high density of (Ca,Sr)d states at the Fermi level, whereas the growth of TC in going from Sr(GaxSi1 – x)2 to Ca(AlxSi1 – x)2 is associated with the increase in phonon frequencies due to the decrease in atomic masses. Simulations are performed for the electronic properties of hypothetical (11,11) and (20,0) CaAlSi and SrGaSi nanotubes. In going from the crystalline to the nanotubular state, the silicide systems retain metal-like properties. The template and “film rolling” techniques can be used for obtaining silicide nanotubes

Аннотация: For the first time, the α-Ag2S (acanthite)–β-Ag2S (argentite) phase transformation in nanocrystalline and coarse-crystalline powders of silver sulfide has been observed in situ by the scanning electron microscopy method in real-time. The argentite crystals are formed on the surface of acanthite particles as a result of electron-beam heating. According to the differential thermal analysis data, the transformation occurs at a temperature of ∼449–450 K, and the enthalpy of transformation is equal to ∼3.7–3.9 kJ mol−1. The presence of α-Ag2S (acanthite)–β-Ag2S (argentite) phase transformation is confirmed in situ by high-temperature X-ray diffraction data.

НЕОРГАНИЧЕСКИЕ НАНОТРУБКИ -- ФУЛЛЕРЕНОПОДОБНАЯ СТРУКТУРА
Аннотация: Back in 1992 it was proposed that nanoparticles of layered compounds will be unstable against folding and will close up into fullerene-like structures (IF) and nanotubes. In the years that followed nanotubes and fullerene-like structures were synthesized from numerous compounds with layered structure. More recently, crystalline and noncrystalline nanotubes of compounds with a 3D, i.e., quasi-isotropic lattice have been intensively investigated. In view of their eminent applications potential, much effort and substantial progress has been achieved in the scaling-up of the synthesis of inorganic nanotubes and fullerene-like nanoparticles of WS2 and MoS2 and also other compounds. Early on it was suggested that hollow nano-octahedra consisting of a few hundred MoS2 moieties make the true analogs of C60, etc. This notion has been advanced considerably in recent years through a combined experimental–theoretical effort. tribological applications and lately for impact resilient nanocomposites. These tests indicated that IF-MoS2 and IF-WS2 are heading for large-scale applications in the automotive, machining, aerospace, electronics, defense, medical and numerous other kinds of industries. A few products based on these nanoparticles have been recently commercialized by “ApNano Materials, Inc” (“NanoMaterials, Ltd.”, see also www.apnano.com). Most recently, a manufacturing facility for the commercialization of these nanomaterials has been erected and sales of the product started. Novel applications of inorganic nanotubes and fullerene-like nanoparticles in the fields of catalysis; microelectronics; Li rechargeable batteries; medical and optoelectronics will be discussed

Аннотация: Nanocomposite coatings based on crystalline TiC phase with 3-8 nm grain size embedded in an amorphous hydrocarbon a-C:H matrix are deposited by pulsed magnetron sputtering of Ti-target in Ar/C 2H 2 gas mixture ionized by pulse (50 kHz, 10 μs) low-energy (100-400 eV) electron beam. The effects of acetylene flow rate, substrate bias and ion current density on composition and hardness of the coatings have been investigated by XRD, XPS and indentation tests. The hardness of TiC/a-C:H coatings raised by 20 % then ion current density increased by 30 % due to increasing of electron beam current up to 1 A. Adhesive coatings with 5 μm thick, hardness of ~ 5-35 GPa and deposition rate of 1.4 1.9 μm/h have been obtained.

Аннотация: An amorphous-nanocrystalline Gd2O3 powder with a specific surface area of 155 m2/g has been prepared using pulsed electron beam evaporation in vacuum. The nanopowder consists of 20- to 500-nm agglomerates formed by crystalline nanoparticles (3–12 nm in diameter) connected by amorphous-nanocrystalline strands. At room temperature, the Gd2O3 nanopowder exhibits a paramagnetic behavior. The phase transformations occurring in the powder have been investigated using differential scanning calorimetry and thermogravimetry (40–1400°C). The amorphous phase of the nanopowder is thermally stable up to a temperature of 1080°C. It has been found that the amorphous phase has an inhibitory effect on the temperature of the polymorphic transformation from the cubic phase into the monoclinic phase. It has been revealed that, compared with the microcrystalline powder, the Gd2O3 nanopowder is characterized by a complete quenching of photoluminescence.

Аннотация: The electronic structure and magnetic properties of the crystalline and fullerene-like forms of nickel dichloride NiC² are investigated in the framework of the local spin density functional theory. It is demonstrated that the band gap can be reproduced in the energy band spectrum of the NiCl² compound with inclusion of the magnetic ordering in the calculation of the band structure. The metamagnetic nature of the NiCl² dichloride (i.e., the transition from an antiferromagnetic phase to a ferromagnetic phase in a weak magnetic field) is explained in terms of a small difference (0.025 eV/cell) between the total energies of the ferromagnetic and antiferromagnetic phases. Polyhedral three-shell nanoparticles of the NiCl² compound exhibit magnetic properties (the magnetic moment of nickel lies in the range 2.0–2.3 µβ). For isostructural nanoparticles of the FeCl² dichloride, the magnetic moment of iron is larger and falls in the range 4.2–4.5 µβ, whereas nanoparticles of the CdCl² dichloride are found to be nonmagnetic. The results of analyzing the interatomic interactions indicate that the composition of fullerene-like nanoparticles of the dichlorides under investigation can deviate from the 1 : 2 stoichiometric composition

Аннотация: A comparative analysis of the stability factors and electronic structure of two possible crystalline forms of small fullerene C28 and endohedral fullerene Zn@C28 with diamond and lonsdaleite structures is performed using a cluster model. Atoms of elements that, when placed inside C28 cages, have no significant effect on the stability of free small-fullerene molecules are shown to be able to dramatically change the electronic properties and reactivity of the C28 skeleton and to be favorable for forming small-fullerene crystalline modifications, which are covalent crystals. In contrast, if the presence of foreign atoms inside C28 cages stabilizes the isolated nanoparticles, then molecular crystals (such as C60 fullerites) are formed due to weak van der Waals forces
