Relevance of the research topic is due to the global trend towards the development of clean energy, in particular, the utilization of carbon dioxide. Recently, electrocatalytic reduction of carbon dioxide has been considered as a promising way to utilize carbon resources and produce sustainable fuels. Due to the limited energy efficiency, uncontrolled selectivity, low stability, and uncertain mechanisms of electrocatalytic CO2 reduction, there are still many complex problems to be solved. In this regard, current research in the field of electroreduction of CO2 is relevant. Sustainable and cheap catalysts need to be developed for the electroreduction of carbon dioxide. This paper presents a review on sodium pectate with manganese as a catalyst in the carbon dioxide reduction reaction. It was experimentally proven that sodium pectate with manganese exhibits catalytic properties in carbon dioxide reduction as the overvoltage was reduced by 400 mV. The stability of this complex was also tested for some time, the current for 8 hours increases, which means that sodium pectate with manganese can maintain its catalytic activity in the carbon dioxide reduction reaction for a long time. In the future, this complex can replace other more expensive catalysts.

In recent years, there has been a significant increase in interest in spicy-aromatic and essential oil plants, which are used as natural plant raw materials in pharmacy, medicine, food, processing and perfumery-cosmetic industries. One of the very promising species of these plants is the Dracocephalum moldavica. The article presents the results of studies on the study of growth regulators and microfertilizers Siliplant, Zircon, Ferovit and Albit, on the productivity of the Dracocephalum moldavica. The best result of the application on experimental plots in the prevailing weather conditions in 2022 was the drug Ferovit. The average yield of dry raw materials was 4.26 t/ha and seeds 325.0 kg/ha, which is more than the control variant by 42% and 54%, respectively.

The long-term dynamics of the average annual and seasonal air temperature on the territory of the Moscow region is considered. To assess the significance of linear trends in annual and seasonal air temperature, the criterion “trend-to-noise ratio” was used, calculated according to the method of V.E. Chuba. In addition, statistical criteria were used the Spearman criterion and the correlation coefficient. It has been established that the highest value of annual air temperature, falls on the territory of the city of Moscow, where its own special microclimate is created, and the lowest value of the average annual air temperature is observed at the weather station Mozhaisk. When analyzing the trend in the rate of increase in annual air temperature, the following results were obtained. The increase in the average annual air temperature over the period for Moscow is 2,61 °C/74 years, for the southeastern part of the Moscow region (Kolomna) is 2,26 °C/97 years and for the western part of the region from Mozhaisk) is 2,36/90 years. Checking the significance of linear trends showed that in the dynamics of the average annual, seasonal and maximum and minimum air temperatures in the Moscow region, there is a positive statistically significant linear trend.

The environmental doctrine of the Russian Federation proclaims the principle of equal attention to the economic, social and environmental components of sustainable development and the recognition of the impossibility of the development of human society in the degradation of nature. Economic growth should not be accompanied by a deterioration in the state of natural environments, at the same time, environmental protection should not lead to the economic weakening of the city. The goal of environmental sustainability is to conserve natural resources and develop alternative energy sources while reducing pollution and harm to the environment. Existing sustainability challenges urgently call for new urban solutions, which in turn require experimentation at the right scale and with multiple stakeholders. This is where urban living labs have a key role to play. The article considers the possibilities of using Urban Living Labs in the implementation of the concept of sustainable development of cities, the problems of achieving environmental sustainability of the city.

This article proposes for comparison different concepts of approaches to urban planning: the experience of domestic urban planning in the form of a natural frame and a system of green areas is studied, the experience of foreign researchers is studied on the example of green and landscape infrastructure, productive landscapes and landscape urbanism. For comparison, three levels of perception of the territory are singled out: the macro-level (highest level), the meso-level and the micro-level (lowest level). The levels of large and small scale showed the difference in the approaches of domestic and foreign researchers. The experience of foreign researchers is based on the search for local solutions to environmental and urban problems. Domestic experience has a lot of knowledge in the organization of complex structures that link the city and nature around it. Urban green building trends are to find a balance on all three levels.

The article considers the problem of control systems for unmanned aerial vehicles reliability increasing, which are used for environmental monitoring and agricultural needs. Software systems reliability improving can be achieved through the use of N-version software, which often uses an algorithm for voting by an agreed majority. However, this algorithm can select the presumably correct answer of a entire module randomly. This happens when several groups of versions of the same amount give different answers. To solve this problem, the article proposes to modify the voting algorithm by an agreed majority by applying a common diversity metric. The paper describes the common diversity metric, as well as a couple of particular metrics included in it (the programming languages diversity metric and the algorithm diversity metric). The method of modifying the voting algorithm by an agreed majority is also given. In the article conclusion the results were summed up, and a conclusion was made about the expediency of using a common diversity metric to modify the vote algorithm by an agreed majority in order to increase the reliability of unmanned aerial vehicles for environmental monitoring and agricultural purposes.

The main problem of the modern world is the difficulty of obtaining high-quality water necessary to meet the needs and improve the quality of life of people. Many territories of our country have large reserves of groundwater with a huge mineralization of effluents that are not used in water supply, due to the large content of various impurities and salts in the water. To use this water in artesian water supply, it is necessary to remove salts from it. Among the many methods of desalination of wastewater, we compare two methods – electrodialysis and reverse osmosis, competing for the opportunity to prevail in the modern energy market. The most important criteria for comparing the effectiveness of water desalination methods are: preliminary preparation of the liquid; how often the membranes fail during operation of the equipment; energy savings of processes, reduction of current and capital costs for water filtration. Electrodialysis is a chemical process in which the number of electrolytes in a liquid changes under the influence of an electric current, more often this method is used at normal atmospheric pressure in industrial plants. Reverse osmosis is a method of desalting liquid to obtain purified water for the national economy.

Nitrogen dioxide causes great harm to the environment when it released into the atmospheric air. Therefore, it is necessary to monitor and determine the concentration of NO2 in the air with fast response gas sensors. In recent years, sensors based on semiconductor metal oxides have attracted ever-increasing attention. This interest is mainly related to their properties (magnetic, optical, electrical and catalytic). In this paper, we present a technique for obtaining oriented nickel oxide fibers for use as an active element in a nitrogen dioxide gas sensor. Obtaining oriented nickel oxide fibers was carried out by two-stage synthesis at a temperature of 70°C by reducing nickel chloride N𝑖𝑖𝑖𝑖𝑖𝑖2 ∙ 6𝐻𝐻2𝑂𝑂 in an alkaline medium in the presence of a magnetic field. The process was followed by thermal oxidation in air. A silicon substrate was used as the basis of the active element. The appearance of oriented nickel oxide fibers was studied using a confocal microscope.
