A new installation for growing carbon nanotubes (CNT) by the chemical vapor deposition (CVD) method has been developed, which made it possible to obtain CNTs with a diameter of 2±0.5 nm at a temperature of 500°C using a nickel catalyst. The CNTs obtained were studied by the Raman spectroscopy method; the results show that they belong to single-walled ones.

The expediency of use of returning technologies in the processes of gas-phase production of silicon epitaxial structures for solar cells, which previously proved themselves well in the chloride production of raw…
The complex formation of Nile blue acetate (NSA) and oxazine 1 dyes with sodium dodecyl sulfate (SDS) and Triton X-100 (TX-100) has been studied by the steady state and picosecond resolved fluorescence spectroscopic…
The sequential generation of the 3-rd harmonic in quadratic nonlinear optical crystals with an inhomogeneous domain structure has been studied by a numerical method. The case is considered when the thicknesses of the…
The low efficiency of UV-laser ablation of transparent alkali-silicate glass has been increased by means of irradiation by 60Co γ-quanta to doses 104 −107 Gy to induce intensive UV-visible coloration. Varying the…

The ZnS crystal was irradiated by electron beam with an energy of 2 MeV and fluences from 0.5×1017 electron/cm2 to 1.5×1017 electron/cm2 . The initial structure of ZnS is in line with the cubic phase (sp.gr. F-43m)…
The paper presents the results of photometric processing of digital images of a new double gravitationally lensed quasar SDSS J2124+1632 observed at Maidanak observatory. The light curves showed that the brightness of…
It is determined that the spectral dependence of the photocurrent covers a wide range of incident photon energies from 1.07 eV to 3 eV. It is shown that with an increase in the temperature of the onset of…
The Praesepe open star cluster is studied in detail based on high-precision observational data. Processing and analysis of all astrometric, kinematic and photometric data are made in a wide area covering the Praesepe…
Sb2Se3 crystalline films were obtained by chemical molecular beam deposition (CMBD) from separate sources of the Sb2Se3 binary compound and the Se element, at a substrate temperature of 500°С. The main strong peaks…
