Wastewater from chemical, metallurgical, processing, enrichment and galvanic industries is characterized by increased content of heavy metal ions (HM), extremely high salt organic pollutants content. Heavy metals in industrial wastewater are hazardous for ecosystems due to their non-biodegradability and toxicity. Various methods have been developed to remove HM ions from industrial wastewater. The adsorption method remains one of the effective ones due to its ease of operation, cost-effectiveness, wide range of available adsorbents and ability to remove both organic and inorganic pollutants. In this paper the background salinity effect on the copper, nickel and zinc ions removal from model wastewater by adsorption process was studied. Activated carbon BAU-A was used to extract HM ions from a model wastewater solution. Sodium chloride and sodium sulfate were used in different concentrations (up to 200 g/L) at pH 2.5. We found that maximum Cu(II) removal efficiency was 97% with 50 g/L NaCl content. The maximum Ni(II) and Zn(II) adsorption (58 and 75% respectively) was in solution with 50 g/L and 150 g/L NaCl+Na2SO4 (1:1), respectively, after 2-hour sorption process in the reactor. The study examined the effect of time on sorption on the efficiency of the metal ion extraction process. The maximum Cu(II) sorption was after 3 hours of the sorption process and it was 98% in Na2SO4 solution (100 g/L). The study showed that the extraction efficiency by sorption decreases in the Cu – Zn – Ni series. The salt content and sorption time has significant effect on adsorption of HM ions.

The effectiveness of plasma-chemical air purification technology was studied in comparison with some technologies for suppressing waste gases (adsorption, catalysis). We use proven approaches (environmental-economic, expert, hierarchical evaluation procedure and the criterion of relative overall benefit) to selecting systems for neutralizing volatile pollutants. Thus, environmental-economic and expert approaches, as well as the criterion of relative overall benefit, make it possible to compare technologies based on operating costs (technological risk, energy efficiency, reliability and cost of production assets). At the same time, the hierarchical evaluation procedure, in addition to the listed indicators, takes into account ergonomics and resistance to external influences. It is shown that plasma-chemical cleaning technology is not a priority when choosing systems for neutralizing waste gases from formaldehyde, since 3 out of 4 approaches indicate the ineffectiveness of this technology relative to the adsorption method. When cleaning air from formic acid vapors, plasmachemical technology in 2 out of 4 cases is as effective as the adsorption method. The effectiveness of plasma-chemical, catalytic and adsorption technologies is considered from the point of view of the methodology for assessing the “carbon footprint”, which makes it possible to quantitatively study the emission of “greenhouse gas” not only at the stage of equipment operation, but also at the stages of production, transportation and disposal. However, the obtained carbon footprint values for low-temperature plasma are the best among comparable available technologies, because the total amount of CO2 emissions when using it is reduced by 80% (on average) due to the fact the relative total energy costs are lower.

The phytoremediation potential of species of the genus Salix L. (Willow) was studied during the remediation of the industrial landfill of the OJSC “Karelsky Okatysh”. A plantation was created at this landfill in 2014. 7 species of the genus Salix were used for this purpose. The technogenic soil of the landscape was contaminated with iron up to 56 g/kg and was poor in basic macro- and microelements. Biomorphological (growth, organ weight) and physiological indicators (photosynthetic pigments content, leaf cell wall composition), as well as metal accumulation (biological absorption coefficient of metals (BAC)), were analyzed for willow plants during 4 years. We found that S. schwerinii (93%), S. phylicifolia (80%), and S. viminalis (70%) had the maximum survival rate after planting. The photosynthetic pigments content and the special leaf index (SLA) of S. phylicifolia and S. shcwerinii leaves allowed us to evaluate the photosynthetic function of plants as optimal in conditions of soil iron contamination and a lack of macro-microelements. The average series of metal accumulation by a whole plant in species of the genus Salix is as follows: Zn (31.92) > Cd (11.83) > Mn (5.10) > Pb (4.64) > Cu (4.40) > Cr (1. 47) > Co (1.45) > Li (0.41) > Fe (0.17). Due to the high ion exchange capacity of the willow leaf tissues cell wall (1120–2050 µmol/g of dry cell wall weight), metals can µind in the plant µody. Phenolic and pectin suµstances dominate in the structure of the cell wall of willow leaves. Willows will continue to perform the function of afforestation of technogenic territory and create conditions for the development of a productive forest phytocenosis.

The study was conducted to identify the effects of elevated concentrations of PM2.5 and PM10 particles in the air on the morphometric parameters of erythrocytes in children. Two areas with similar geoclimatic conditions but different exposure to these particles were selected. The concentrations of PM2.5 and PM10 were measured using scanning electron microscopy. In-depth investigations were conducted on 360 children, and general clinical indicators of whole blood were analyzed. Statistical analysis tools in the Python programming environment were used for data analysis, and a two-layer neural network was employed to predict morphometric changes in erythrocytes. Evans models and a complex surface model were also applied to simulate erythrocyte shape. The average daily concentration of PM10 exceeded the observed level but did not reach the permissible limit (MPC=0.060 mg/m3). The content of PM2.5 was significantly higher in the comparison area and exceeded the average daily permissible concentration (MPC=0.035 mg/m3). The research results revealed significant differences (р=0,0001) between the observation and comparison groups in the indicators of whole blood, especially in color index and mean erythrocyte volume. Correlation analysis established a connection between various blood parameters, hemoglobin concentration, and the level of PM2.5 and PM10 particle concentrations in the air. Based on neural network modeling, a mathematical model was developed to predict the influence of various factors on the mean erythrocyte volume. The model showed that increased PM2.5 concentration is associated with a decrease in mean erythrocyte volume, which may indicate premature aging. Overall, this study contributes to new scientific findings on the relationship between air pollution and morphometric parameters of erythrocytes in children. It can aid in the development of more effective health protection strategies and the reduction of the negative impact of air pollution on the population.

The parameters of vegetation cover – a tool for capturing carbon from the atmosphere – vary widely depending on the latitudinal-zonal conditions of the area and local microclimate features. In this regard, the most promising approach to assessing the carbon balance of the territory is the analysis of net primary productivity and, accordingly, the possibilities of capturing carbon from the atmosphere by landscapes of various natural zones, differing in the types of vegetation cover, soil, microclimate and other landscape-ecological characteristics. The aim of the study is to assess the possibilities and patterns of carbon sequestration by vegetation of mountain-forest, mountain-steppe and steppe landscapes of Russia. The research was carried out at seven study plots in the Chechnya Republic and the Orenburg region. At the first stage, the indicators of net carbon sequestration by vegetation for 2000–2020 were calculated on the basis of MOD17A3 products that allow estimating gross primary productivity and net primary productivity. At the second stage, the regularities of the formation of the ability to capture carbon by the vegetation cover of each study plot, depending on climatic and meteorological conditions, on the basis of regression modeling were revealed. It was found that the foothill plot with a multi-year mixed forest and the absence of anthropogenic impact demonstrates the maximum ability to capture carbon from the atmosphere – from 2.6 to 3.5 kg/m2/year. The plot of a natural perennial dry steppe is characterized by a minimum carbon capture capacity – from 0.5 to 1.5 kgF/m2/year. Regression models of the dependence of the sequestration carbon indicators on climatic and meteorological characteristics have been created. These models demonstrate the relative stability of the ability of long-term natural vegetation cover to absorb carbon from the atmosphere.

Forests occupy a dominant position in the vegetation cover of the Komi Republic and play a key role in maintaining ecological balance in the Subarctic region. In recent decades they have been subjected to intensive development and technogenic impact, which leads to degradation and destruction of significant areas of taiga forests. The main factors affecting the composition, structure and condition of these forests are logging, fires, windthrow, pests, diseases, aerotechnogenic emissions from industrial enterprises and energy facilities. Application of the landscape approach to monitoring and protection of taiga forests implies assessment of vitality structure of stands. The aim of this work was to assess the vital state of stands of coniferous and deciduous forests at the test site “Lyalsky”, organized in 2023 in the middle taiga of the Komi Republic. The research was carried out on 29 permanent sample plots created in the most common forest types in the region. The test site territory is covered with mature and ripe spruce and pine formations, as well as overmatures birch and aspen forests. These stands form mixed, medium- and low bonitet, mixed-age stands representing different types of plant communities with different moisture levels. The results show that the stands on the site are generally characterized as healthy, with high tree vigour. Only in some areas with deciduous species (birch, aspen) there is a slight weakening of their condition, which is due to the preservation of old specimens of trees or competitive relationships between young individuals. The results obtained will be used to compare data on the vital state of trees with estimates of phytomass and carbon stocks in forests in specially protected areas, and will also serve as a basis for long-term monitoring at the landscape level.

Disintegration of water nanodroplet in oil: Impact of amphiphile self-assembly, surface heterogeneity, and protrusions
Authors: Kumar Nitesh
Published: January 2025

Amphiphiles self-assemble around water-in-oil nanodroplets, increasing interfacial heterogeneity, reducing droplet size, and stabilizing the system through microemulsion formation. We present molecular dynamics simulations investigating how amphiphiles modulate the heterogeneity and disintegration of water nanodroplets. Utilizing network theory-based sub-ensemble analysis and curvature analysis, we characterize the amphiphile self-assembly process and the disintegration of water nanodroplets into smaller daughter droplets. We detail the microscopic mechanism of water transport from the water droplet to the oil phase, facilitated by the formation of sharp, finger-like protrusions on the droplet surface. Our results demonstrate a direct correlation between the rate of droplet disintegration and temperature-induced thermal fluctuations.
Precise PBAEs: A Highly Efficient Single-Molecularly Defined Gene-Delivery System

Published: January 2025

Gene-delivery polymers have wide therapeutic applications. The structures (e.g., molecular weight, polymer sequence, end groups, and topology) of gene-delivery polymers are of crucial importance to their properties including transfection efficiency, toxicity, and targeting capability. Thus, precise control over the structures of gene-delivery polymers is extremely beneficial for property optimizations and manufacturing reproducibility. However, sequence-defined gene-delivery polymers with high efficiency and low toxicity are rare, limited by synthetic strategies. In this work, we developed a method that enables poly(beta-amino esters), one of the most promising gene-delivery polymers, to be synthesized with precisely controlled and vastly variable molecular weight, end group, and topology. The precise PBAEs exhibited advantages over the corresponding random PBAEs (i.e., the same high level of transfection efficiency at a much lower molecular weight), and their defined structures unambiguously revealed new design principles for gene-delivery polymers.
Kinetics of Carboxylic Acid Enolization on Metal Oxides in Vapor Phase

Published: January 2025

An invisible, reversible, previously overlooked catalytic reaction — enolization — occurs consistently when carboxylic acid vapors contact metal oxide surfaces. A relatively strong acidity of the CO2H group in carboxylic acids is responsible for the formation of the conjugate base, carboxylate, adsorbed on Lewis acid centers of metal oxide surfaces. Acidity of the alpha C-H group is much weaker and hidden from direct observations during carboxylic acids interaction with metal oxide surfaces, but it is detectable through hydrogen – deuterium isotopic exchange. Subsequent condensation of the enolized carboxylate with another surface carboxylate comes into play in the mechanism of ketones formation with decarboxylation, an important part of oxygen removal during upgrading of biofuels. In this kinetic study, the rate of approaching equilibrium was measured for H/D isotopic exchange on alpha-carbon of isobutyric acid used in various concentrations in a vapor phase mixture with D2O as well as for the reversed H/D exchange between alpha-deuterated isobutyric acid and H2O upon contact with monoclinic zirconia and anatase titania catalysts. Faster rate for H/D vs. D/H exchange points to alpha-deprotonation, i.e., enolization, as the rate determining step of the exchange mechanism. The intrinsic rate of the enolization was deduced using McKay equation for equilibrium reactions. The kinetic activation parameters were obtained through the temperature dependence of the rate constant for both exchange directions, H/D and D/H. KOH doping on ZrO2 changes the geometry of the transition state leading to higher rates of enolization and increasing H/D kinetic isotope effect from 1.4 to 8.3. The opposite effect of KOH doping is observed on anatase TiO2 – enolization rates are slightly decreased, the kH/kD remains relatively constant at 2.7-2.8 indicating that the nature of basic centers on TiO2 is unaffected. These kinetic study results confirm that C-C coupling, not enolization, is the rate limiting step of the decarboxylative ketonization mechanism.
A Fast Computational Framework for the Design of Solvent-Based Plastic Recycling Processes

Published: January 2025

Multicomponent plastics cannot be processed using mechanical recycling technologies, hindering efforts to deal with plastic waste. Multicomponent plastics include multilayer plastic films, which are widely used for food and healthcare packaging. Multilayer films combine several layers (potentially dozens) of different polymers to protect products from external factors (e.g., oxygen, water, temperature, shock, and light). Solvent-based separation processes have emerged as a promising alternative to recycle these complex materials. For instance, the Solvent-Targeted Recovery and Precipitation STRAP (TM) process uses sequential solvent washes to selectively dissolve and separate constituent polymers from multicomponent plastic waste, including films. STRAP (TM) process design (separation sequence, type of solvents, and operating conditions) changes significantly depending on the design of the multilayer plastic film (e.g., number, types, and proportions of polymers). The ability to quickly quantify the economic and environmental benefits of diverse STRAP (TM) process designs is essential to accelerate the development of sustainable recycling processes and more recyclable multilayer film products. In this work, we present a fast computational framework that integrates molecular-scale models, process modeling, and techno-economic and life cycle analysis to quickly evaluate STRAP (TM) designs. The computational framework is general and can be used to study the processing of complex multilayer plastic waste streams that contain many layers. We highlight the different uses of the framework via targeted case studies.
El migrante ambiental en el contexto de los estudios de seguridad. Niveles de (in) seguridad y vulnerabilidad
Authors: Ruiz Guzman Lucero De Jesus
Published: January 2025

Percibir a la migración por causas ambientales desde la perspectiva de la seguridad nacional atenta contra la dignidad y seguridad del migrante ambiental, toda vez que éste se encuentra en un escenario de vulnerabilidad distinto al resto de los migrantes forzados. Por tal, desde una metodología cualitativa a través del método deductivo y del sistema de indicadores sociales para medir situaciones de vulnerabilidad social de Bauer, se sustenta que el migrante ambiental se halla en un escenario de vulnerabilidad particular, ello al confrontar conceptos/indicadores como (in) seguridad, amenaza y riesgo. Así, se concluye que a través de la norma y/o política que regula un fenómeno considerado como amenaza (migración ambiental), se puede llegar a escenarios adversos, que provoquen mayor inseguridad para los migrantes, por lo que es necesario retomar las bases de la seguridad humana.

Montages in the peri-urban palimpsest. Echographies for Leuven
Authors: Gerrits Yuri , De Meulder Bruno
Published: January 2025

This article delves into the debate on the peri-urban condition that surrounds Belgium’s cities and towns. It uses the case of Leuven as an example to unravel the territory’s unique though confusing structure that until this day remains largely tailored to its rural basis. This article moves in the slipstream of Corboz’ writing on “the land as a Palimpsest” and puts the focus on the intricate duality of vernacular and urban orders.  More than relying on the ideals of postulated models, it explores the use of a method that seeks to rationalise the imperfection and alleged chaos, unveiling recurrent, emergent patterns of a hybrid order instead. A cartography of “Echographies” is proposed as a new tool to facilitate the indispensable deep reading and interpreting of the peri-urban condition. But it is also instrumentalised in support of a more customized approach of “architectural urbanism” that considers design as a continued transformation of what is already in place.

Penelitian ini menganalisis pengaruh profitabilitas, leverage, pertumbuhan penjualan, dan ukuran perusahaan terhadap penghindaran pajak pada perusahaan sektor industri, basic materials, dan consumer non-cyclical di Bursa Efek Indonesia (BEI) periode 2021-2023. Metode analisis yang digunakan adalah Multiple Regression Analysis (MRA). Hasil penelitian menunjukkan bahwa profitabilitas dan leverage memiliki pengaruh signifikan terhadap penghindaran pajak, sedangkan pertumbuhan penjualan dan ukuran perusahaan tidak. Profitabilitas berpengaruh negatif, artinya semakin tinggi profitabilitas, semakin rendah penghindaran pajak. Sebaliknya, leverage berpengaruh positif, menunjukkan semakin tinggi leverage, semakin tinggi penghindaran pajak. Hasil ini sesuai dengan teori keagenan dan teori legitimasi, di mana perusahaan dengan profitabilitas tinggi cenderung mematuhi pembayaran pajak untuk menjaga reputasi, sedangkan perusahaan dengan leverage tinggi cenderung menghindari pajak untuk mengurangi beban keuangan. Penelitian ini memberikan wawasan bagi pembuat kebijakan, akademisi, dan praktisi bisnis tentang dinamika penghindaran pajak di Indonesia.

Comprehensıve analysıs of the opportunıtıes of ecotourısm ın the lıberated regıons
Authors: Ibadulla Isa Muradov
Published: January 2025

Ecocultural tourism, a new type of tourism brought about by the relationship between cultural and nature tourism, aims to develop cultural and ecological resources by presenting the ecological and cultural components of the landscape together. Sustainability and participation are two key factors crucial to the long-term future of tourism. Appropriate strategies should be defined to realize the potential of ecotourism, which carries all the principles of sustainability, and ecocultural tourism, where nature is valued together. Within the framework of these strategies, the concept of "eco-museum" that preserves the natural and cultural environment as a whole comes to the fore in international practice. The joint use of eco-cultural heritage in the liberated territories allows for the creation of this strategy. In particular, the wide potential of territories freed from occupation for the use of cultural and natural heritage creates favorable conditions for the development of eco-cultural tourism.

The article investigates the definition of indicators of effective assessment of energy security of Ukraine in the implementation of renewable energy technologies based on SWOT analysis. Priority of implementation of technologies using energy of renewable sources on leveling of threats to energy supply of the country is defined. The scientific and methodological approach to assessment of innovative development of Ukraine in the system of energy security using a modified model of SWOT analysis is substantiated. The advantage of the model is compactness of development due to the use of a single platform and efficiency of use due to the absence of the need to reload data into a specialized system. With the help of fractal analysis, a graphical interpretation of the comparison of SWOT analysis components in the innovative development of Ukraine in the system of energy security is built. The peculiarity of the proposed model lies in the fact that the data, having both qualitative and quantitative characteristics, are subject to analysis. As a conclusion, it is proposed to carry out an economic analysis of the factors influencing the prioritization of key technologies in the Ukrainian industry.

Strengthening of environmental standards of agricultural management, environmentally oriented modernization of industrial enterprises, including the traditionally dirtiest ones, modernization of transport allow to improve the quality of environmental management. Considering the transition to the paradigm of sustainable development in all spheres of social life, especially in tourism, the study of the potential for the development of rural green tourism is particularly relevant, especially under the conditions of the need to support agriculture. Approaches to state and legal regulation of rural tourism are considered on the example of leading European countries and Ukraine. Characteristics of rural tourism as a separate field of tourist activity are identified. It is shown that rural tourism is an important tool for achieving the goals of sustainable development, and its development requires simplification of bureaucratic procedures and harmonization of European and national legislation. On the example of Petrykivka municipality of Dniprovsky district ( Dnipropetrovsk Оblast) the expediency of creating a single network of green farms, connecting them with cycling, horseback riding and hiking trails, and further organizing a cluster of rural and ethnographic tourism for promotion of tourist products under a single brand of the local hromada is considered. The importance of cluster development of tourism enterprises in Dnipropetrovsk Oblast and Petrykivka hromada is based on the need to create more flexible structures capable of satisfying the growing demand for quality and environmentally friendly services. In recent years, small and medium-sized enterprises in the field of tourism have been among the leaders of growth in terms of services and goods provided in the region. At the same time, these green tourism enterprises have not only significant tourism potential, but also experience in cooperation and interaction.
The effect of the advanced construction projects implemented in the Karabagh region during the post-occupation period on the perspective development of tourism in Azerbaijan
Authors: Elshad Masim Yusifov
Published: January 2025

After the end of the 30-year period of occupation, the restoration and rebuilding of the liberated lands has become one of the most important and urgent problems facing the country. In the post-occupation period, that is, in the last two years, important steps have been taken by the Azerbaijani state in the development of Karabakh. Great work has been done in the direction of ensuring security, infrastructure construction, agriculture and tourism. The projects implemented, in progress and planned to be implemented in the future in the liberated lands will have a significant impact on the development of tourism in the Karabakh region. It should be noted that the correct assessment of the potential of these areas, their future development and, most importantly, the development of tourism will make a significant contribution to the restructuring and development of Karabakh, as well as to the development of the Azerbaijani economy towards the non-oil sector. Karabakh region is a region with rich tourism potential. Here there are opportunities for the establishment and development of various types of tourism. Simply, the destruction of these lands by Armenians and the destruction of infrastructure during the occupation are rapidly slowing down the development of tourism in Karabakh. The total reconstruction value of the liberated Karabakh region is measured in billions. It is not possible to carry out these works and to revive Karabakh and to carry out these works quickly at the expense of the country's economy. It should be noted that last year, 4,4 billion manats were allocated from the state budget for the implementation of the work in Karabakh. However, the estimated appropriation for the complete restructuring of Karabakh is more than 50 billion manats. Therefore, ensuring and increasing the investment flow to this region is one of the other urgent issues. In Karabakh, which has the opportunity to develop at the world level in the next 10-15 years with its own tourism potential, it is very important to research and apply the world tourism management in terms of methodology in order to benefit from these opportunities of the tourism sector. If the experiences of many developed countries in this field are applied correctly and in a planned manner in Karabakh, the region will become one of the leading regions of the world tourism sector.
