Item Polymer materials: bibliographic data analysis and trend detection(National Society of Enviromental Science and Engineeruing, 2021) Черниш, Єлізавета Юріївна; Черныш, Елизавета Юрьевна; Chernysh, Yelyzaveta Yuriivna; Balintova, M.; Рой, Ігор Олександрович; Рой, Игорь Александрович; Roi, Ihor Oleksandrovych; Demcak, S.Alternatives to waste management methods include the reorganization, recycling, and creation of environmentally friendly biodegradable polymer materials based on renewable resources, plant, and textile waste. The goal of this study is to analyze bibliographic data and identify trends in research on polymer materials of different genesis, with particular attention to research on the production and use of biopolymers. VOSviewer v.1.6.15 is used to present the analysis results. Environmental impact areas in the life cycle of traditional polymers have been analyzed. The network of main bioplastics clusters is visualized within the framework of modeling the dependencies on the main keywords in the analysis of the dynamics of publication activity, the main trends in the development of new biodegradable materials are revealed. A comparative review of the environmental impact of different types of bioplastics is made by the life cycle assessment method.Item Study of the Magnetic Water Treatment Mechanism(Bentus, 2020) Васькіна, Ірина Валеріївна; Васькина, Ирина Валерьевна; Vaskina, Iryna Valeriivna; Рой, Ігор Олександрович; Рой, Игорь Александрович; Roi, Ihor Oleksandrovych; Пляцук, Леонід Дмитрович; Пляцук, Леонид Дмитриевич; Pliatsuk, Leonid Dmytrovych; Васькін, Роман Анатолійович; Васькин, Роман Анатольевич; Vaskin, Roman Anatoliiovych; Яхненко, Олена Миколаївна; Яхненко, Елена Николаевна; Yakhnenko, Olena MykolaivnaThe main problem of widespread introduction of magnetic water treatment (MWT) in the processes of water and wastewater treatment is the lack of modern research aimed at studying the mechanisms of MWT effects, in particular the influence on the physicochemical properties of aqueous solutions. This study explains the effect of MWT taking into account the physical and chemical properties of aqueous solutions due to the presence of the quantum differences in water molecules. All the MWT effects are related to the change in the physicochemical properties of aqueous solutions. It is due to the presence of two types of water molecule isomers and their librational oscillations. The result of MWT is a violation of the synchronism of para-isomers vibrations, with the subsequent destruction of ice-like structures due to the receiving of energy from collisions with other water molecules (ortho-isomers). One of the most important MWT effects includes the change in the nature and speed of the physicochemical processes in aqueous solutions by increasing the number of more physically and chemically active ortho-isomers. The MWT parameters specified in the work allow explaining the nature of most MWT effects and require developing the scientific and methodological principles for the implementation of the MWT process and mathematical modeling of the MWT process in the water and wastewater treatment. It can be used in the design of the MWT devices taking into account the constructive and mode parameters of MWT devices.Item The magnetic water treatment(Сумський державний університет, 2013) Рой, Ігор Олександрович; Рой, Игорь Александрович; Roi, Ihor OleksandrovychThere are many intensification destinations for water purification. The most common is the use of effective technological schemes, modernization and development of new methods. Their implementation in practice is not always possible due to technical, economic and other reasons.
