The purpose of the present study was to develop a nano-coating for fresh vegetables and fruits using a combination of curcumin, sesame oil, stearic acid, and dextran (CSSDNs). The anti-bacterial and nontoxic nature of nanoparticles were tested against Gram-positive bacteria (Staphylococcusaureus) and human fibroblast cells. Enhanced aqueous solubility of curcumin and its stability in the bloodstream were observed from the in vitro blood compatibility studies. The anti-cancer activity of curcumin-loaded nanoparticles was tested against SK-BR3 cells, demonstrating excellent antitumor activity. These findings indicate that the CSSDNs system can be used as an edible coating with strong antibacterial properties and as an effective means of delivering curcumin, which has proven to be successful in treating or preventing cancer.

The article reports the Satbayev University’s studies on deformation monitoring of engineering structures, in particular, the Abay Avenue/Saina Street interchange in the city of Almaty in the Republic of Kazakhstan. Almaty is situated in the region of increased seismic activity, including the main artery of the city—its subway that runs along the Abay Avenue. It is shown that the problem connected with safe operation of unique engineering structures can be solved using the integrated monitoring, encompassing all natural and manmade factors and their analysis, with the authorial procedure and equipment of geodetic surveying. The research utilized an integrated approach, including: geological and geotechnical analyses of rock mass structure and tectonics, instrumental geodetic surveying with the use of GPS technologies, electronic tacheometry and ground-based scanning, as well as assessment of measurement accuracy. The basic network deployment procedure is developed for the deformation monitoring of bridges, and geodetic monitoring of the test traffic interchange and above-ground buildings is performed. The use of electronic tacheometers and laser scanning with the satellite geodesy techniques in the geodetic monitoring is justified. For the installation of high-precision electronic and laser devices for the ground surface geomonitoring, the authors have designed a permanent station which provides fast and accurate centering without tripods. Based on the accomplished studies, the authors propose the subsidence and displacement determination methods for engineering structures. The research findings are included in a scientific project and in education and training courses. The obtained results are usable in enhancement of industrial safety at other objects for the minimiza-tion of seismic risks in the region.

The study is devoted to the analysis of soil pollution in the West Kazakhstan region with heavy metals and hydrocarbons as a result of intensive activities of the oil and gas and mining industries. The main attention is paid to the determination of pollutant concentrations, their spatial distribution and the impact on ecosystems. It has been established that the region’s soils are long-term accumulators of man-made pollutants, including heavy metals (lead, cadmium, arsenic, chromium, nickel) and hydrocarbons. Key industrial zones of the region, such as Khromtau, Aktobe, Karachaganak field and oil refineries, have been selected as objects of study. Field and laboratory studies were carried out using generally accepted sampling methods (GOST 17.4.4.02-2017) and chemical analysis (atomic absorption spectrophotometry, X-ray fluorescence analysis). Geostatistical data analysis was carried out using GIS technologies (ArcGIS), which made it possible to create spatial maps of the distribution of pollutants. The results showed that the concentrations of heavy metals in the studied soils exceed the maximum permissible values (MPC). For example, near large industrial facilities, the concentration of chromium reaches 7333.6 mg/kg, nickel – 2213.1 mg/kg, and arsenic – 19 mg/kg. It has been revealed that soil pollution is accompanied by a deterioration of their physico-chemical characteristics, a decrease in fertility and a threat to ecosystems. The problem is aggravated by the migration of toxic substances into reservoirs and their accumulation in biota, which poses a danger to public health. Monitoring methods, including chemical, bioindication, and geostatistical approaches, as well as innovative soil purification technologies such as bioremediation and the use of nanotechnology, are proposed to minimize environmental damage. The results of the study are important for the development of state programs for the restoration of polluted lands, reducing anthropogenic pressure and ensuring sustainable development of the region.

For effective adaptation to the rapidly changing conditions of the external environment and the implementation of economic activity, a necessary condition for the effective management of sustainable development is theoretical research into the mechanism of its provision according to the vector of innovation. Within the framework of this chapter, a systematic approach to the formation and implementation of the strategy of sustainable innovative development of transport enterprises is outlined, which allows determining the main methods and tools used in order to improve the efficiency of the enterprise's functioning, both in the current period and in the future. At the same time, it is important to note that the strategy of sustainable development includes two main directions-the mechanism of enterprise restructuring to achieve long-term sustainable development and the management policy of short-term sustainable development of enterprises. Methodological approaches have been developed to determine the mechanism of sustainable innovative development, which is a set of subsystems and elements that regulate the process of managing the innovative activity of the enterprise. It is substantiated that one of the most important conditions for the functioning of the mechanism of sustainable innovative development of the enterprise is the formation of the necessary volume of financial resources. In case of limited access to financial resources of developed countries, the main source is the company's own resources. This made it necessary to develop a methodology for the formation of funds for targeted financing, which, based on the characteristics of innovative transformations, are determined by the characteristics of internal investment and venture funds.
The accident at the Chornobyl Nuclear Power Plant (ChNPP) in Ukraine in 1986 became one of the largest technological disasters in human history. During the accident cleanup, a special protective structure called the Shelter Object was built to isolate the destroyed reactor from the environment. However, the planned operational lifespan of the Shelter Object was only 30 years. Therefore, with the assistance of the international community, a new protective structure called the New Safe Confinement (NSC) was constructed and put into operation in 2019. The NSC is a large and complex system that relies on a significant number of various tools and subsystems to function. Due to temperature fluctuations and the influence of wind, hydraulic processes occur within the NSC, which can lead to the release of radioactive aerosols into the environment. The personnel of the NSC prevents these leaks, including through ventilation management. Considering the long planned operational term of the NSC, the development and improvement of information technologies for its process automation is a relevant task. The purpose of this paper is to develop a method for managing the ventilation system of the NSC based on neuro-fuzzy networks. An investigation of the current state of ventilation control in the NSC has been conducted, and automation tools for the process have been proposed. Using an adaptive neuro-fuzzy inference system (ANFIS) and statistical data on the NSC's operation, neuro-fuzzy models have been formed, which allows to calculate the expenses of the ventilation system using the Takagi-Sugeno method. The verification of the proposed approaches on a test data sample demonstrated sufficiently high accuracy of the calculations, confirming the potential practical utility in decision-making regarding NSC’s ventilation management. The results of this paper can be useful in the development of digital twins of the NSC for process management and personnel training.

The pilot study is devoted to the assessment of both the accumulation and spatial distribution of microplastics in the snow cover of the Zhetysu region. The height of snow cover in the study area varied from 4.0 to 80.5 cm, with a volume of melt water ranging from 1.5 to 143 L. The analysis of 53 snow samples taken at different altitudes (from 350 to 1500 m above sea level) showed the presence of microplastics in 92.6% of samples in concentrations from 1 to 12 particles per square meter. In total, 170 microplastic particles were identified. The main polymers identified by Raman spectroscopy were polyethylene (PE), polypropylene (PP), and polystyrene (PS). These are typical components of plastic waste. The spatial distribution of microplastics showed elevated concentrations near settlements and roads. Notable contaminations were also recorded in remote mountainous areas, confirming the significant role of long-range atmospheric transport. Particles smaller than 0.5 mm dominated, having high aerodynamic mobility and capable of long-range atmospheric transport. Quantitative and qualitative characteristics of microplastics in snow cover have been realized for the first time both in Kazakhstan and in the Central Asian region, which contributes to the formation of primary ideas and future approaches about microplastic pollution in continental inland regions. The obtained results demonstrate the importance of atmospheric transport in the distribution of microplastics. They indicate the need for further monitoring and microplastic pollution analyses in Central Asia, taking into account its detection even in hard-to-reach and remote areas. © 2025 by the authors.

This study investigates photocatalytic cells based on cocatalyst-loaded SrTiO3:Al and nano-SiO2 as a porous binder, immobilized on frosted glass. Comprehensive analysis confirmed the successful incorporation of aluminum into SrTiO3, increasing oxygen vacancy concentration and enhancing charge transfer. The deposition of RhCr2O3 and CoOOH cocatalysts significantly improved photocatalytic activity, boosting hydrogen and oxygen evolution rates to 3.8401 and 1.6319 mmol g−1 h−1, respectively. The introduction of nano-SiO2 increased hardness (0.23–0.25 GPa) and Young’s modulus (5.27–5.40 GPa), reinforcing structural integrity. The development of efficient photocatalytic panels requires a multifaceted strategy that considers chemical, mechanical, and optical properties together with stability, durability, and energy efficiency. Future research should focus on optimizing these key parameters to enhance system performance for industrial applications.

Thin transparent films of SnO2 were obtained from aqueous–alcohol solutions of SnCl4 on a flexible polyethylene terephthalate (PET) substrate by spray pyrolysis at 100 °C. The influence of the addition of aqueous ammonia to the film-forming solution on the different properties has been studied. Properties studied include surface morphology, phase composition and transparency of the formed films and the crystallization processes and band gap of the film material. It was found that the addition of aqueous ammonia causes the formation of skeletal crystals (NH4)2[SnCl6] with a perovskite structure in the film structure. The resulting films are promising for use in the technology of manufacturing flexible solar cells. © 2024 by the authors.

With the increasing need for digitalization in mining production, the relevance of applying modern geodesy and surveying technologies, particularly using digital communication systems and satellite navigation, has significantly increased. Scientific and technical progress has enabled the development and implementation of high-precision measurement technologies that significantly surpass traditional methods in performance and accuracy. A differential correction base station utilizing GNSS (Global Navigation Satellite Systems) data for measurements is created as a part of the geodetic work automation at Kacharsk deposit. This article presents the development of a software and a technical facility for a high-precision satellite positioning system, which has successfully passed all testing stages and has been implemented in industrial operation. This integrated system allows measurement tasks to be performed in real-time and post-processing modes, taking into account the complex conditions of signal transmission at the depths of quarries and beyond the dumps. The work was conducted by the D.A. Kunayev Mining Institute in collaboration with the Institute of Space Technique and Technology. The project co-financing by a private partner JSC "SSGPO". The development includes creating a differential correction center, which facilitates the transmission of correction information and differential corrections to mobile devices at the site. This provides the increased measurement accuracy and optimized production management processes in the constantly changing geometry of the quarry. A software-based mathematical algorithm for processing and analyzing satellite data has been developed within the project, significantly enhancing the efficiency of geodetic measurements. The implementation of satellite technologies not only improves the accuracy and efficiency of geodetic works but also promotes the digital transformation of the entire production process at Kacharsk deposit. Such developments are a key element in the strategy of creating an "intelligent mine", where all processes are maximally automated and optimized to ensure safety, efficiency and sustainability of production. In the context of sustainable development, the adoption of these technologies also contributes to minimizing the environmental impact of mineral extraction through precise positioning and planning of mining, leading to reduced waste and optimized resource usage. Financing and support for such projects highlight the importance of integrating science and technology into the sustainable development of the industry.
