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

Аннотация: The gas-sensing properties of nanostructured vanadium oxide doped with alkali-metal cations (MxV2O5 with M = Na, K, Rb, and Cs) have been studied by measuring the resistance of films as a function of analyte content using an impedance meter. The results show that the doped vanadium oxide is sensitive to hydrogen, carbon monoxide, and ammonia in the concentration ranges 0.1–80, 0.1–5, and 0.1–5 vol %, respectively. The strongest gas response is offered by Rb0.47V2O5, which is due to the smallest interlayer spacing in the structure of this nanomaterial and to its larger specific surface area

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

The electronic state, charge distributions, and parameters of interatomic interactions are analyzed in nanotubular composites M@NT depending on the NT structure ((9.0) or (4.4)) and position of the M atom (at the end or in the center of the NT) and depending on the cluster symmetry (Th or Td) and positions of M atoms in the metal–carbon cage for “substituted” metcars Ti7MC12. Possible changes in some physicochemical properties of the nanotubes and metallocarbohedrenes with the indicated 3d atoms are discussed

Аннотация: We have performed ab initio calculations to systematically investigate electronic properties and magnetism of insulating non-magnetic beryllium monoxide nanotubes (BeO NTs) induced by nonmagnetic sp impurities: boron, carbon and nitrogen, as well as by nanotube wall defects: Be or??O vacancies.We found that in the presence of these sp impurities, which replace oxygen atoms, the nonmagnetic BeO NTs transform into magnetic semiconductors, which acquire magnetization caused by spin splitting of (B, C, N) 2p states located in the forbidden gap of a BeO tube. The magnetic moments of the impurities vary from 0.65 to 1.60mB. It was also found that a beryllium vacancy leads to vacancyinduced magnetic moments (at about 0.6mB) arising on the nearest oxygen atoms and berylliumdeficient BeO nanotubes adopt half-metallic-like properties. On the contrary, when (B, C, N) dopants??substitute for Be atoms or in the presence of an oxygen vacancy, the non-magnetic state of the BeO??tubes is retained. The results obtained have been compared with theoretically predicted magnetization effects for doped and non-stoichiometric crystalline BeO

Аннотация: The electronic structures of undoped anatase and anatase doped with carbon and vanadium have been calculated using the ab initio tight binding linear muffin tin orbital (TB-LMTO) method in the LSDA + U approximation. It has been shown that the doping of TiO2 leads to the formation of narrow bands of the C and V impurity states in the band gap. The calculations of the imaginary part of the dielectric function have made it possible to estimate the intensity of the optical absorption. It has been established that the doping with vanadium and carbon leads to optical absorption in the visible range and to an increase in the absorption in the ultraviolet range up to 4 eV. This should result in an increase in the photocatalytic activity on the surface of the doped anatase. The experimental determination of the photocatalytic activity of whiskers of the anatase doped with carbon and vanadium in the reaction of hydroquinone oxidation has confirmed the increase in the activity of the doped materials under exposure to ultraviolet, visible, and blue light. The phenomenon of dark catalysis in the anatase doped with carbon and vanadium has been interpreted within the concept of low-energy electronic excitations between the impurity levels of carbon

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

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: 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

Аннотация: The band structure and thermal behavior of a coaxial C/BN nanocable (5,5)C@(17,0)BN consisting of a carbon nanotube and a boron nitride nanotube have been studied using a tight-binding approximation based on density functional theory. The system is stable up to T ~ 3500–3700 K. As the temperature increases, deformations of the BN tube begin earlier than those of the carbon tube. The near-Fermi states of the nanocable are formed by the overlapping p–p* bands of the carbon tube, and the outer BN nanotube (the nanocable sheath) is an insulator with a bandgap of ~4 eV. The electronic properties of the nanocable (the metallic-type conductivity of the C tube and the insulating character of the BN tube) are retained over the entire temperature interval

Аннотация: Atomistic simulations are performed to investigate the structural, mechanical and electronic properties of a coaxial C/BN nanocable under axial elongation using molecular dynamics. Our results show that the mechanism of the breaking process essentially differs from those for initial single-walled carbon and BN nanotubes. The formation of a carbon as well as a -C-B-N-atomic chain connecting two cable fragments before fracture is obtained, and due to such bridges the cable can be stretched until complete rupture up to epsilon max~29% as compared with epsilon max~23% for a single-walled carbon nanotube. After breakage the opposite tips of cable fragments form different individual atomic morphologies and compositions and can have promising potential as electron emitters. The Young moduli of the C/BN cable and C-NT are comparable. An analysis of the electronic structure shows that during tensile deformation the C/BN cable retains the basic electronic characteristics (metallic-like for the inner carbon nanotube and dielectric for the outer BN tube); however, the bandgap between the highest occupied N 2p and lowest unoccupied B 2p states decreases from 4.0 to 1.2 eV

The structural, elastic, and electronic properties and the energies of formation of these crystals were calculated using the density functional-based tight binding (DFTB) method. The crystals proposed were found to exhibit extreme compression moduli (550–650 GPa) and a minimum compressibility (0.0018–0.0015 GPa–1); in this case, the type of conduction of the parent nanotubes was retained. For this reason, the above crystals are of interest for the development of new superhard materials with controllable electrophysical properties

Аннотация: Using ab initio simulation of manganese, aluminum and carbon impurities in fcc Fe, we demonstrated the features in their distribution, which involves repulsion of interstitial carbon atoms, formation of Mn–C pairs as well as short range Al-ordering of the D03-type. We modeled the formation of stacking faults (SF) and analyzed the impurity effect on the intrinsic stacking fault energy (SFE), which controls the plasticity mechanism in austenitic alloys. First, we found that impurities have an influence on the SFE only when they are located within a few atomic layers near a stacking fault. As a result, the SFE is highly sensitive to the concentration of impurities in the vicinity of stacking fault defect. Aluminum and carbon as well as manganese for concentrations higher than 15 at.% increase the SFE, while the formation of Mn–C pairs and Al-ordering restrain the SFE growth. Short range Al-ordering strongly decreases the unstable stacking fault energy (USFE) making the formation of the stacking fault much easier, but does not affect the SFE that can explain the observed planar glide deformation before the occurrence of mechanical twinning regardless of the SFE.
