“…According to D'Olier-Lees et al ( 2023), the renewable energy sector is expected to grow significantly in the coming years, but some challenges need to be addressed. The transition to renewable energy will require significant investment, and the industry will need to navigate headwinds such as supply chain disruption, trade policy uncertainty, and interconnection delays (Alkaabi and King 2019;Dinzhos et al 2020). However, the deployment of renewable energy technologies is expected to mitigate the economic impact of the energy crisis and reduce wholesale electricity prices (Marino et al 2018;Fialko et al 2022).…”

“…Further discussions and research are needed on the duration of the use of VR and drones in student education to prevent possible misuse of technology and ensure sufficient efficiency of technology use. The development of drone technology is leading to the use of drones in various fields, including education [2], [41], [42], [43]. However, this necessitates training to ensure quality use and to consider the learning and perception of children of different ages.…”

Employment of various innovative tools for education in the post-epidemic era is an urgent issue of improving the quality and efficiency of education and the relevance of educational material. The study aims to investigate the impact of the use of drones and virtual reality in educational models of student learning in the post-pandemic period. The study was conducted using a quantitative method, a sociological survey, a pedagogical experiment, and mathematical processing of the results. The study involved fourth-year students (n=748) studying in the following specialties: geography and ecology (n=119), engineering, robotics (n=135), architecture and urban planning (n=120), agriculture, agronomy (n=118), information technology (IT) (n=139), journalism (n=117), and teachers (n=258) with more than 5 years of experience. For the educational process of students of each specialty, the scope of application of drones and virtual reality has been developed. Classes with the use of drones and virtual reality were held two times a week for one academic semester. Afterward, students were interviewed using an adapted questionnaire to study their attitudes toward virtual reality technologies and drones for learning. Students of all specialties positively evaluated various aspects of the use of drones and virtual reality in their educational process. The use of drones helps to improve student engagement and visual attention and has a positive impact on learning efficiency and student satisfaction with the learning process. Teachers approve of the use of drones and virtual reality in teaching but point out that further development of the methodology for training stakeholders in the educational process, infrastructure, improvement of curricula, and consideration of various aspects of technology use is needed to effectively implement drones and virtual reality in the learning process. The practical significance of this study is to present aspects of the use of drones in teaching students of certain specialties and to study the impact of the effectiveness of the use of these technologies on the opinions of students and teachers.

This paper reports the experimental study carried out to establish the dependence of the thermal conductivity of polypropylene-based nanocomposites filled with carbon nanotubes on the main parameter of the temperature regime of their manufacturing ‒ the level of overheating a polymer melt relative to its melting point. The study has been conducted for nanocomposites that were manufactured by applying a method based on the mixing of components in the polymer melt applying a special disk extruder. During the composite manufacturing process, the level of melt overheating varied from 10 to 75 K, with the mass share of filler ranging from 0.3 to 10.0 %. It is shown that increasing the overheating of a polymer melt causes an increase in the thermal conductivity of the composites. However, when the overheating has reached a certain value, its further growth does not increase the thermal conductivity of nanocomposites. Based on the established pattern, the rational level of this overheating has been determined. That resolves the tasks of manufacturing highly heat-conducting nanocomposites and implementing appropriate energy-saving technology. Data have been acquired on the effects of the impact of the amount of polymer melt overheating on the values of the first and second percolation thresholds for the examined nanocomposites. It is established that the value of the first percolation threshold is more sensitive to the specified amount of overheating. The dependences of the density of the examined composites on the level of polymer melt overheating have been derived. The correlation between a given dependence and the nature of a corresponding change in the thermal conductivity of the composites has been established. Applying the proposed highly heat-conducting nanocomposites is promising for micro and nanoelectronics, energy, etc.
