Аннотация: The article presents experiments on obtaining composite fibers based on Shubarkol coal tar (CT) and polycarlonitrile (PAN) by electrospinning in a laboratory setup. As a result of energy dispersive X-ray spectroscopy and SEM microscopy, the elemental composition (C-85.83%) and the diameter of the carbon fiber were determined, which ranged from 89.0 nm to 449.8 nm. The resulting CNF was subjected to oxidation in air at 300 °C, the holding time was 1 hour, after which the carbonization process was carried out at 800 °C, followed by cooling to room temperature.

Development of technology for extraction of lead and zinc oxides from dust and slags during the utilization of lead plant waste. [Текст] / K. Zhantassov // News of national academy of sciences of the republic of Kazakhstan. . - 2021. - №2. - P. 81-85

Аннотация: The article proposes methods for the extraction of lead and zinc from slag waste and selects the optimal method for the selective extraction of zinc and lead oxides from dust and slags of lead production. The proposed technology of continuous carbon-free selective extraction of zinc and lead from the dust of electric steelmaking production allows the use of lead production slag, which is fed into a rotating drum furnace in two oppositely directed streams. During the movement of lead slag in the furnace drum and the burning of the torch, lead and zinc are more completely extracted from the dust-like material, where the transporting object is compressed air, and the purified flue gas after the gas is further purified by means of a smoke pump is released into the atmosphere.

Аннотация: In the present paper, the issues of studying the influence of complex activation of grouting fluid on the structure and properties of the hardened cement paste and concrete are considered. The problem is relevant for manufacturing of building materials. In the paper, there was used the method of applying in the concrete mix composition of the elementary chemical substances undergone special physical treatment by means of mechanomagnetic activation. For more profound study of the structure formation processes in the hardened cement paste, the method of differential thermo gravimetric analysis has been used. As the research results have shown, the concrete samples on the activated electrolyte solutions are characterized by improved strength. In addition, on the base of differential thermo gravimetric analysis, it was proven that in the studied samples of the hardened cement paste on the electrolyte solutions activated by the method of mechanomagnetic treatment, the less calcium hydroxide and the more hydrated calcium silicate with amorphous and fine crystalline is formed. The obtained results for cement composites could be applied when manufacturing effective binder for concretes and mortars in the production of building materials and structures.

Аннотация: In the course of continuation of scientific research in the development of Kazakhstani technology for the production of trimanganese tetraoxide pigment, there have been proposed new methods of analysis which make it possible to investigate new nanostructural materials sourced from local deposits. The results obtained are of practical importance and serve as the foundation for developing new technologically advanced domestic production of a competitive product that is in demand both on the national and international markets. The available methods are not able to highlight the particularity and diversity of Kazakhstani manganese ores due to the uneven distribution of manganese minerals and host (waste) rock, the quantitative ratio of rock-forming components and their variation instability. Methods of energy-dispersive analysis of manganese ores from Kazakhstani Zhaksylyk and Bogach deposits have been put forward, electronic micrographs, spectrograms of samples, diagrams of normalized distribution of elements on the surface of samples have been obtained and a comparative analysis with raw analogue samples of some foreign manufacturers has been performed.

Аннотация: This scientific article is devoted to the problems associated with the flow of suspensions and emulsions and some simplifications of the real picture of the flow of a polydisperse medium are made. It is also stipulated that differential equations characterizing the motion of suspensions and emulsions should take into account the fundamental discontinuity of the medium and the physicochemical processes of heat and mass transfer occurring in it. Taking into account all these factors, a general equation for multiphase systems is proposed with certain simplifications that do not change.

Аннотация: Засоление почв является одним из самых общеизвестных процессов деградации земель. Антропогенное воздействие на почвенный покров и экосистемы Казахстана во всех географических зонах каждым годом возрастает. В данном исследовании была рассмотрена в базе данных HWSD картографические материалы по засоленным почвам Казахстана. Засоленные почвы преобладают в южных и центральных районах Казахстана. Галофитные растения могут являться одним из ресурсов, которые могут быть эффективными в борьбе с засоленной средой. В статье представлены результаты экспериментов при обработке семян Suaeda salsa Pall различными концентрациями солей (Na2SO4 и NaCl) и почвенными экстрактами (0%, 0.6%, 1.2%, 1.8%, 2.8%, 3.6%). Наблюдали реакцию проростков и молодых корней растений Suaeda salsa Pall, выращенных после обработки растворами солей и почвенными экстрактами. Кроме того, по результатам роста молодых корней и побегов, выращенных в условиях солевого стресса, было проведено сравнительное описание темпов роста проростков и молодых корней до и после солевого стресса. Результаты эксперимента показали, что семена сохраняют высокую всхожесть, не смотря на высокие стрессовые условия солей (Na2SO4 и NaCl) и растворов почвенных экстрактов, влияющих на семена Suaeda salsa Pall. Наблюдались значительные изменения в скорости роста молодых корней и побегов растения Suaeda salsa Pall во время и после солевого стресса, а также улучшении скорости прорастания семян после стресса. Выявлено, что темпы роста молодых корней и побегов Suaeda salsa Pall в разных солевых растворах (Na2SO4 и NaCl) различаются, солевые растворы значительно подавляют рост корней проростков Suaeda salsa Pall по сравнению с раствором почвенного экстракта, концентрация соли в большей степени оказывает влияние на корни растения. Установлено, что после снятия солевого стресса всхожесть и регенерационная способность проростков Suaeda salsa Pall повышаются.
