One of the methods of obtaining polymer films that exist today is electrospinning, the advantages of which are the relative simplicity of the technological process and the possibility of obtaining continuous nanofibers from both synthetic and natural polymers. In this work, the influence of various process parameters on the formation of nanofiber mats from a biodegradable synthetic polymer by electrospinning was studied.

When obtaining raw materials necessary for construction from quartz mineral, it is pre-crushed to the desired size. New methods and technologies are proposed to improve the processes of grinding solid materials. One of these methods is the electric pulse method. This method is designed for grinding solid materials with the formation of pulsed electrical discharges in a liquid volume. When processing natural ores by the electric pulse method, the resulting products are not contaminated with metal in the working chamber. The paper analyzes the granulometric composition of quartz powder and determines the degree of grinding of raw materials depending on the parameters of electrical pulse discharges. The investigations on the processing of raw materials were carried out at various parameters of the number of pulse discharges and discharge voltage. In experiments, quartz fractions with a diameter of 10 mm were crushed by the electric pulse method and a product with a diameter of 0.4-1 mm was obtained. Since quartz is crushed in a liquid medium, the amount of water consumed was studied to obtain the necessary granulometric composition of raw materials. The dependences of the degree of quartz grinding on the number of pulse discharges and the discharge voltage are obtained. The results of grinding the material by pulsed electrical discharges allow us to evaluate the main parameters of the process implemented in the electro-pulse method of destruction of solid material.","PeriodicalId":29904,"journal":{"name":"Bulletin of the University of Karaganda-Physics","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46301351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the model, the component contributions of each of the fields are determined to the total density and pressure of dark energy. We have considered the solution of the cosmological model for the scale factor with two functional time dependences. The Yukawa-type field does not give its input to the general pressure. In the power law case, there is a significant contribution to the total increase in pressure, to the exponential — the scalar field. There are many cases when the universe makes a transition between successive epochs in various models of cosmological expansion. These regularities impose some restrictions on the profile of the scalar- fermionic field interaction and the general cosmological dynamics. Energy conditions were found to check the model under the study. In the studied model, the null energy condition, the strong energy condition, the dominant energy condition are fulfilled, and the weak energy condition, which is not mandatory, is not fulfilled. It is shown how it is possible to connect the cosmographic parameters — parameters of deceleration q, jerk j and snap s with the power low the scale factor. We investigated these restrictions using cosmological solutions with an evolving equation of state, such that a smooth transition between different epochs can always occur in the universe. The scalar-fermionic model under study describes the accelerated modes of expansion of the universe. The obtained solutions correspond to the results predicted by the theory and observational data.","PeriodicalId":29904,"journal":{"name":"Bulletin of the University of Karaganda-Physics","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47412073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Zinc oxide (ZnO) is one of the most active semiconductor photocatalysts. In this paper, the influence of the morphology of nanostructured zinc oxide synthesized by effective methods on photocatalytic properties with respect to the rhodamine-B dye (RhB) was investigated, and the influence of the length-to-thickness ratio (aspect ratio AR) of ZnO samples on its structural and optical properties was studied. The results of the study showed that an increase in the annealing temperature of zinc acetate in the atmosphere leads to an increase in the size of zinc oxide crystallites, while an increase in the concentration of alkali in the growth solution (synthesis of ZnO by chemical deposition from 0.4 M to 0.7 M) makes it possible to synthesize thinner extended 2D plates.

It is known that the introduction of TiO2 addition to the BeOceramics after heat treatment in a reducing atmosphere is accompanied by a significant increase in electrical conductivity and the ability to absorb electromagnetic radiation in a wide range of frequencies. According to the results of the studies it was found that the addition of nanoparticles TiO2 into the (BeO + TiO2)-ceramics significantly reduces its static electrical resistance in comparison with the serial sample, and the specific conductivity of such ceramics significantly increases at high frequencies ~ 107 Hz. The addition of TiO2 nanoparticles significantly increases the dielectric losses of the sample sintered in the temperature range 1530 — 1550 °C. The values of real and imaginary parts of dielectric permittivity of such ceramics and the tangent of the angle of dielectric loss are two times higher compared to the serial sample — BT-30 (B — beryllium, T — titanium).
