Abstract:
Currently, the accumulation of thermal energy is an important task not only in traditional thermal energy systems to balance energy supply and demand, but also in renewable energy systems, where energy production can vary greatly. At the same time, special attention is paid to the latent accumulation of thermal energy. This is mainly due to the high energy density that can be stored at the time of its excess generation and the ability to maintain an isothermal regime during phase transitions. This property makes phase transition materials (PCMs) particularly valuable in various thermal energy storage applications. One of the main limitations to the overall efficiency of thermal energy storage systems based on PCMs is the relatively low thermal conductivity of the material used. This determines the rate of absorption and release of heat during the phase transition, which ultimately significantly limits the scope of such storage systems. This article not only examines the role of PCMs in thermal energy storage systems, but also identifies key advantages and several innovative strategies to increase the thermal conductivity of PCMs. These strategies include the addition of ribs, the use of nanoparticles, the implementation of heat pipes, and encapsulation techniques. It is expected that these developments will significantly improve the practice of sustainable energy management and contribute to more efficient use of renewable energy sources using thermal energy storage devices based on phase transition materials. The summary of the study highlights the importance of using phase transition materials to ensure a sustainable energy future where thermal energy storage is an integral part of the functioning of energy systems.

Abstract:
The aim of this review is to substantiate the fundamental feasibility of research and development related to archaeological and anthropological materials within the infrastructure previously utilized for work in physical chemistry, chemical, and biochemical physics. The assessment of capabilities is based on a literature analysis in the fields of archaeometry and archaeological analytics, as well as structural analysis for geoarchaeological and archaeomineralogical applications. On this basis, a plan for several research directions is proposed, where not only specialists in physical chemistry can be involved and trained, but also historians and archaeologists, among others. The user-friendly nature of the modern implementation of these methods allows for their mastery across various (non-physico-chemical) fields of study, starting from the early stages of university education. By not being overly complex in implementation, these research activities will not only enable achieving the standards of progressive foreign archaeometric laboratories but also contribute to DIY science/citizen science, engaging students in the humanities to address their challenges through rigorous scientific methods with higher technical and methodological organization. This will also enhance the methodological quality of certain archaeological publications.

Abstract:
The biographical sketch is dedicated to the 150th anniversary of the birth of the Russian chemist Sergei Vasilyevich Lebedev (1874–1934). The material was biographical research on the life path and scientific heritage of the Soviet academician. The methodology consists of the content analysis method, the synthesis method, etc. Lebedev became famous for his research in the field of synthesis of new polymers. In 1927, he received the world's first industrial synthetic rubber; this discovery played a crucial role in the development of industry in general, and the development of synthetic materials in particular. His work marked the beginning of many modern technologies that are used in the production of rubber and other polymer materials. The scientist actively participated in scientific public life, publishing the results of his research in a number of scientific publications. Lebedev also engaged in pedagogical activities, teaching future generations of chemists and researchers. Sergey Vasilyevich Lebedev became a pioneer in his field of knowledge, and his scientific achievements are widely used to this day. His name has become synonymous with innovations in chemistry and industry.
