Comparative experience of socio-pedagogical work with gifted children in the Russian Federation and Kazakhstan
The authors conduct a comparative analysis of the features and content of socio-pedagogical work with gifted schoolchildren in the educational space of Russia and Kazakhstan. The purpose of our study: to study and present the comparative experience of socio-pedagogical work with gifted children in the Russian Federation and Kazakhstan. Collection of empirical data was carried out by questionnaire survey of teachers of general educational organizations of the Russian Federation (n=225) and educational organizations of Kazakhstan (n=200). The survey of teachers and specialists of educational organizations was conducted in 2018 and 2019.The authors have studied the comparative experience of organizing socio-pedagogical work with gifted schoolchildren in Russia and Kazakhstan. The results allow us to see common and specific in the work with gifted children in the Russian Federation and the former post-Soviet republic. The identified features can be taken into account in the organization of socio-pedagogical work with gifted schoolchildren and improve the effectiveness of socio-pedagogical work and socio-pedagogical support of gifted schoolchildren. In conclusion, the study of comparative experience of socio-pedagogical work with gifted schoolchildren in two countries with a similar history of formation of educational systems allows us to see the difference in approaches to work with this non-standard category of children at the moment. The identified specificity in the programs, forms and methods, target benchmarks of socio-pedagogical work with gifted children in educational organizations can be taken into account when developing the content of this direction of work and will improve its effectiveness
Updating the content of education through the integration of seven modules
The article is devoted to the analysis of modern trends in the field of updating the content of school education of the Republic of Kazakhstan. The introduction of seven educational modules in the content of education will improve the quality of Kazakhstan's education. Finding ways to integrate the seven modules of education makes the study relevant. The author describes the educational modules and their impact on the content of education, focusing on ways to integrate seven modules in a single lesson, changing the content of education under the influence of educational modules
Particular Characteristics of the Synthesis of Titanium Nitride Nanopowders in the Plasma of Low Pressure Arc Discharge
The method of producing TiN nanopowders in the plasma of low pressure arc discharge in nitrogen atmosphere is discussed. The influence of gas pressure on nanopowder dispersion is studied. It is shown that the particles have nanometer size and a narrow particle size distribution
Plasma-chemical synthesis of Fe3O4 nanoparticles for doping of high-temperature superconductors
Abstract Ferrite nanoparticles (Fe3O4) have been produced
by the direct low-pressure plasma-chemical synthesis.
X-ray diffraction (XRD), high-resolution transmission
electron microscopy (HRTEM), vibration magnetometry
(VSM), and Mössbauer spectroscopy (NGR) were used
for measurements, showing that the produced nanoparticles
have an average size of 9.4 nm, a crystalline phase of magnetite,
possess a property of superparamagnetism at room
temperature, and have a blocking temperature of 89 K. The
peculiarities of nanoparticle behavior in the magnetic field,
related to a large specific surface area, are discussed

Investigation into the Peculiarities of Structure Formation and Properties of Copper-Based Powder Pseudoalloys Modified by ZnO and TiN Nanoparticle Additives
Текст статьи не публикуется в открытом доступе в соответствии с политикой журнала.Comprehensive investigations into Cu–ZnO (nano) and Cu–TiN (nano) copper-based materials
by standard methods in combination with metallographic and electron microscopy investigations using
energy-dispersive and thermal analyses make it possible to identify stable correlation relations between the
content of nanoparticle additives, microstructural parameters, and mechanical-and-physical properties of
pseudoalloys. Process procedures of increasing the distribution uniformity of modifying additives of ZnO and
TiN nanoparticles over the pseudoalloy bulk excluding their conglomeration are developed and substantiated.
Novel original methods of nanoparticle introducing into a matrix material in the form of a master alloy made
of Cu–Al–ZnO or copper powders coated with TiN nanoparticles are proposed. A high specific surface and
reactivity of nanopowders make it possible to lower the ceramic phase in electrocontact materials (down to
2.0–3.0% instead of 10–15% when compared with known commercial brands). This results in the conservation
of the main properties characteristic of the matrix material (copper) such as thermal and electrical conductivity
at a rather high level, while the general level of physicomechanical characteristics (hardness,
strength, and wear resistance) and operational properties of composite pseudoalloys simultaneously
increases. The main characteristics of copper-based composite materials are as follows: electrical resistance
(ρ = 0.025 μΩ m), bonding strength to the contact support material (σ ~ 2 MPa), and dispersed ceramic
phase inclusions. They reduce the electroerosive wear (up to a factor of 2.5) when compared with conventional
materials
