КАРБОНОВЫЕ НАНОТРУБКИ -- МАГНИТНЫЕ СВОЙСТВА
Аннотация: The structure and the properties of the quasi-one-dimensional composites, i.e., carbon nanotubes filled with nanowires or clusters of 3d metals (M=Ti, Fe, and Zn), have been studied in the framework of the density functional-based tight binding method. We show that the accommodation of nanosized metal species inside carbon nanotubes (CNTs) may lead to essential changes of the structural, magnetic, and electronic properties ofthe CNTs and the metal species. Especially, we examined the effect of interactions between iron and carbonatoms on the electronic and magnetic properties of the Fen@CNT composites by comparing with freestandingFe wires and clusters. Our calculations support the increasing of the magnetic moments for both wires as well as clusters encapsulated in CNTs in comparison with bulk bcc Fe and show a strong dependence of magnetic moments on the thickness of the wires and on the size of clusters

АНТИОКСИДАНТЫ -- ТУГОПЛАВКИЕ КАРБИДЫ
Аннотация: A study of boron-bcaring additives to periclase-carbon refractories is described. The special features of their oxidation and phase formation in heating ofpericlase-carbon compositions are investigated. It is shown that some of them can be used successfully as an antioxidant component that improves the operational characteristics of periclase-carbon ceramics. It is shown that the imported antioxidant boron-2000 is analogous to amorphous-boron (95 - 85%) preparations, and the latter are recommended for the creation of domestic grades of thermally stable periclase-carbon refractories

КАРБОНОВЫЕ НАНОЧАСТИЦЫ -- ФУЛЛЕРЕНЫ
Аннотация: The relative stability of alternative carbon nanoparticles with icosahedral symmetry, such as diamond-like nanocrystallites and multiwalled fullerenes (onions), is investigated using the parametric model and the density functional tight-binding (DFTB) method. It is demonstrated that an increase in the size of particles and their hydrogenation favor the stabilization of diamond-like nanocrystallites. The formation of “intermediate” nanostructures consisting of diamond-like nanocrystallites inside the fullerene cage is revealed. The electronic spectra of icosahedral carbon nanoparticles are calculated

НАНОПИПОДЫ -- ДИТИТАНОФУЛЛЕРЕНЫ -- КАРБОНОВЫЕ НАНОТРУБКИ
Аннотация: The atomic structure, charge and electronic parameters, and energies of formation of new “hybrid” nanostructures–nanopeapods Ti2@C80@C-NTs, regular linear ensembles of seven isomers of endohedral dititanofullerenes Ti2@C80 encapsulated into a carbon zigzag (19.0) nanotube—have been calculated by the selfconsistent density functional tight-binding method (DFTB). The results are discussed in comparison to the “free” isomers of C80fullerenes andTi2 @C80 endofullerenes, as well as to all-carbon nanopeapods, i.e., C80 isomers inside a carbon nanotube (C80@C-NT). It is demonstrated that the type of Ti2@C80 isomer determines the energy effect of its encapsulation into the tube (exo- or endothermic), the orientational arrangement of endofullerenes in the tube, the charge states of the Ti2@C80 and tube atoms, and the electronic properties of nanopeapods (semiconducting or metallic)

Аннотация: Density functional tight-binding calculations are used to investigate the structure, electronic properties, energy stability, and thermal behavior (0–1500 K) of extended monolithic (nanowires) and hollow (nanotubes) diamond-like carbon nanostructures. The results indicate that diamond-like nanowires and nanotubes may be both metallic and semiconducting, depending on their morphology and size. A new type of hybrid (sp3+sp2) nanostructure is identified, which has the form of a monolithic diamond-like (sp3) wire inside a graphite-like (sp2) shell. Diamond-like nanowires are shown to be more stable than nanotubes of comparable size

Аннотация: Atomic–vacancy ordering in the lowest tungsten carbide W2C with an L'3-type basic hexagonal structure has been studied by neutron diffraction and X-ray diffraction. In the temperature range 2700–1370 K, the only ordered phase of the lowest tungsten carbide is shown to be the trigonal ε-W2C phase (space group P1m). This trigonal ε-W2 C phase is found to form via a disorder–order phase transition channel, which includes three superstructure vectors (k15(1), k15(2), k17(1) ) of two Lifshitz stars ({k15}, {k17}, and to be described by two long-range order parameters (η15,η17). The distribution function of carbon atoms in the trigonal ε-W2C superstructure is calculated, and the orresponding region of the allowable values of the long-range order parameters η15 and η17 is found. Symmetry analysis of other possible superstructures of the lowest tungsten carbide W2C is performed, and the physically acceptable sequence of phase transformations in W2 C is determined

Аннотация: The structure of the nonstoichiometric trigonal (rhombohedral) carbide zeta--Ta4C3 –x forming in the tantalum–carbon system is studied by neutron diffraction, x-ray diffraction, and metallography. The unit cell parameters of the trigonal (space group ) carbide zeta-Ta4C3 –x(TaC0.67) are found to be ah= 0.3123 nm and ch= 3.0053 nm. It is shown that the metallic close-packed sublattice of the zeta-Ta4C3 –x phase consists of alternating blocks in which the metallic atoms are arranged in the same manner as on the fcc sublattice of the cubic carbide TaCy and the hcp sublattice of the hexagonal carbide Ta2C, respectively, and that the former sublattice is intermediate between the latter two sublattices. We are the first to establish experimentally that the distribution of carbon atoms and structural vacancies in the zeta-Ta4C3 – x carbide is ordered and to calculate the istribution function of carbon atoms over the nonmetallic-sublattice sites involved in the ordering. The results obtained for the zeta-Ta4C3 – x phase are used to refine the phase diagram of the Ta–C system

Аннотация: New opportunity to synthesize nano- and ultradispersed powdered materials by combining of two procedures, classical liquid-phase precipitation and low-temperature microwave calcination, at a rather simple instrumentation is described. It was found in precipitation of precursors that, pending on the synthesis conditions (solution pH, amount of carbon, synthesis on the vessel surface or in the solution bulk), particles of hydrated vanadium oxide have different morphologies. It was also found that precursor powders have an insignifi cant microporosity, which is reserved in the fi nal products in trace amounts upon thermal treatment of samples. Intermediate and fi nal vanadium products were synthesized in an electromagnetic fi eld in a fl ow of argon, their phase composition and structure were examined in the stages of thermolysis, reduction, and arbidization, and their lattice constants were calculated. The morphology, size, and particle size distribution in the samples under study were determined.

Аннотация: The ordering of nonstoichiometric VCxNy (x + y = 0.85) vanadium carbonitrides has been studied by x-ray diffraction and optical microscopy. The results indicate that the ordering of VCxNy carbonitrides leads to the formation of a V6(C,N)5 (V6C5 structure) or V8(C,N)7 (V8C7 structure) superstructure, depending on composition. The C and N atoms in the nonmetal sublattice of these superstructures form one sublattice, and structural vacancies form another sublattice. The C and N atoms are arranged at random in their sublattice. Thus, the ordering of vanadium carbonitrides leads to the formation of interstitial and vacancy sublattices, but the carbon and nitrogen atoms do not form separate sublattices. The formation of V6C5- and V8C7-type superstructures in vanadium carbonitrides is accompanied by the breakdown of the grains of the parent, disordered phase into 20- to 40-nm domains of the ordered phase and by the nanostructuring of the bulk material. The formation of the ordered domains begins at grain boundaries of the disordered phase

Аннотация: Structural, thermal, electronic, and energetic properties of cubic boron nitride (BN) nanowires are studied using the density-functional tight-binding method. The effect of the total or partial rearrangement of the cubic structure of nanowires into the hexagonal one depending on the size, morphology, and thermal treatment of the starting wire has been revealed. As distinct from the known homogeneous carbon diamond-like nanowires, stable BN nanowires are two-phase systems whose “shell” has a hexagonal structure and “core” has a cubic structure. The changes in the electronic properties of BN nanowires induced by their structural transformations are discussed. It is shown that boron–nitrogen nanowires can exhibit both semiconducting and metallic properties

Аннотация: The stability and electronic properties of complexes of single-walled carbon nanotubes wrapped by homopolymeric single-stranded DNA molecules (CNT@DNA) are considered using a quantum mechanical density-functional tight-binding method (DFTB). A phenomenological model of the CNT@DNA formation energy depending on the nanotube radii is developed,which shows that the decoration of a CNT by a few DNA chains leads to a high water solubility of CNT@DNA. Pyrimidine-based DNAs are found to be more effective to wrap the CNTs than other DNAs. The densities of states of the CNT@DNA complexes are close to the superposition of those of the ‘free’ components with some additional states below the Fermi level. The band gap in a hybrid CNT@DNA system is determined by the competition between the Fermi levels of the ‘free’ DNA and CNT. In a few specific cases a considerable charge transfer from the DNA to the CNT was observed, combined with an additional gain in the CNT@DNA formation energy
