Аннотация: A methodology to evaluate the kinetic stability of carbon nanostructures is presented based on the assumption of the independent and random nature of thermal vibrations. The kinetic stability is directly correlated to the cleavage probability for the weakest bond of a given nanostructure. The application of the presented method to fullerenes and carbon nanotubes yields clear correlation to their experimentally observed relative isomer abundances. The general and simple formulation of the method ensures its applicability to other nanostructures for which formation is controlled by kinetic factors.

Аннотация: The electron concentration and temperature are measured when elements having various ionization potentials are introduced into the carbon-helium plasma that forms in a high-frequency atmospheric-pressure arc discharge. The effect of the introduced elements on the relative fullerene content in a carbon condensate is also studied. The plasma parameters are determined by in situ emission spectral analysis during the synthesis of fullerene derivatives with scandium, sodium, and silicon. The variation of the atomic and molecular line intensities of the plasma radiation with the distance from the carbon-arc axis is investigated upon the introduction of various doping substances. The optimal temperature conditions for the synthesis of fullerene derivatives with Sc, Na, and Si are found.

Аннотация: Fullerenes containing manganese and iron atoms are synthesized in a high-frequency carbon-helium plasma at atmospheric pressure. The electron paramagnetic resonance (EPR) spectrum of the synthesized compound contains not only lines attributed to iron atoms but also the lines of a manganese ion pair with an additional hyperfine structure. The latter lines are assigned to the endohedral complex Mn-2@C-n (n 70). The possible existence of these structures is evaluated from quantum-chemical calculations of the optimum geometry of the endohedral fullerene Mn-2@C-84 with C-2V symmetry. It is found that the manganese atoms are spaced similar to 2.72 angstrom apart at the center of the molecule.

Аннотация: The influence of the carbon cluster charge on their coagulation kinetics has been studied. The equations of kinetics have been solved and it is established that allowance for the cluster charging leads to an increase in the rate of fullerene formation under otherwise equal conditions. In connection with this, the role of minor impurities with a low ionization potential in carbon-containing plasma is discussed. (C) 2003 MAIK "Nauka/Interperiodica".

Аннотация: A new scheme of fullerene formation is proposed on the basis of the similarity between the experimentally detected carbon structures. According to experimental data, the microclusters of C(2) and C(10) are synthesized first and then either an intermediate nucleus cluster or an obtainable lower fullerene is assembled from them. A high-symmetry fullerene can be assembled with a high probability from a nucleus cluster with a "good" symmetry. The atomic and electronic structures of molecules such as C(36), C(60), C(70), and C(76) are analyzed. For C(36), the NMR spectra are calculated and compared with the experimental data.

Аннотация: The electronic structures of all the possible isomers of endohedral and exohedral C(60) fullerene complexes with two lithium atoms are theoretically investigated. It is found that the electronic structures of these compounds are characterized by an impurity filled-level state determining the band gap. The location of the impurity state and, correspondingly, the band gap of the exohedral fullerene complexes depend on the coordination mode and the distance between the alkali metal ions. A similar dependence is observed for the total energy of the exohedral fullerene complex under investigation. (C) 2001 MAIK "Nauka/ Interperiodica".

Аннотация: The atomic and electronic structure of some endo-, exo-, and endo-exohedral complexes of the fullerene C-60 with various guest atoms and molecules (He-n, H-2, and Li-2) are investigated using semiempirical and nonempirical quantum-chemical methods. The atomic core dynamics is studied by the method of molecular dynamics. It is shown that guest atoms and molecules in fullerene polyhedra acquire an orbital angular momentum due to the correlated motion of nuclei above the low-energy barriers of the potential surface within the carbon polyhedron even at low temperatures (from 4 to 78 K). The emergence of orbital angular momenta of nuclei of guest atoms and molecules is attributed to a change in the contribution of the orbital angular momentum of electrons to the potential surface of the complexes. The motion of Li ions in a polyhedron leads to blurring of the top of the valence band and to the emergence of a charge polarization wave in the carbon polyhedron.

Аннотация: Calculations for a one-dimensional model of RF heating of a cylindrical graphite conductor have been carried out. The heating dynamics are analyzed in the general form. Conductor temperature profiles and the times for heating up to the graphite sublimation temperature as a function of current and frequency have been obtained. A model of conductor heating with partial return of the energy irradiated by the conductor surface has been considered. Frequency and current ranges have been determined to carry out this graphite sublimation method in a chamber with reflecting walls. The problem is associated with carbon vapor production and subsequent synthesis of fullerenes and other carbon structures. (C) 2000 MAIK "Nauka/ Interperiodica".
