Item type: Item , Influence of the content of dispersed fillers of various nature in polyvinylidene fluoride on its structural parameters and thermal conductivity(E3S Web of Conferences APEC-VI-2023, 2023-08-10) Rakhmankulov, AlikulIn this work, a comprehensive study of the effect of graphite and bronze particles on the structure and thermal conductivity of polyvinylidene fluoride (PVDF) was carried out. Based on the experiments carried out, it was found that at the limit of a relatively small concentration of bronze, the melting point of PVDF exceeds, and this was confirmed by an increase in the longitudinal dimensions of the crystallites. With relatively small amounts of fillers contained in the polymer composite materials (PCM, it was written that the change in thermal conductivity occurs mainly due to changes in the polymer structure. It was found out that the change in the structure of the polymer component in the compound and the thermal conductivity largely depends on the nature of the fillers.Item type: Item , Modeling the efficiency of photovoltaic and photothermal batteries using python software(IV МЕЖДУНАРОДНАЯ НАУЧНО-ТЕХНИЧЕСКАЯ КОНФЕРЕНЦИЯ «АКТУАЛЬНЫЕ ПРОБЛЕМЫ СИСТЕМ ЭЛЕКТРОСНАБЖЕНИЯ», 2025-11-04) Xoliqov, Komil Nurmahmatovich; Турсунов, Мухаммад; Сабиров, Хабибулло; Холов, Уйгун; Эшматов, МансурAbstract. Photoelectric batteries have the ability to convert the flow of solar radiation directly falling from the sun to the earth's surface into electrical energy, and provide the needs of all production facilities and the population. However, external factors (air temperature, solar radiation and various types of dust) affect the efficiency of photoelectric batteries. By reducing the above-mentioned effects, it is possible to achieve an increase in the efficiency of the production of electric energy and an increase in the service life of photoelectric batteries. In this paper, to improve the performance of the photovoltaic battery, a study was conducted on cooling through a parallel channel cellular polycarbonate heat collector. In addition, studies were conducted using a reflector to increase the amount of solar radiation falling on the front surface of the photoelectric battery (close to the value in the reference of the photoelectric battery, i.e. 1000 W/m²) and to protect against night dusting.Item type: Item , FIZIKA FANINI O'QITISHNING VOSITALARI(O‘ZBEKISTON RESPUBLIKASI OLIY TA’LIM, FAN VA INNOVATSIYALAR VAZIRLIGI “TIQXMMI” MILLIY TADQIQOT UNIVERSITETI XALQARO ICARDA MARKAZI “TIQXMMI” MTUning QARSHI IRRIGATSIYA VA AGROTEXNOLOGIYALAR INSTITUTI GLOBAL IQLIM O‘ZGARISHI OQIBATLARI, SUV TANQISLIGINI YUMSHATISHNING HOZIRGI HOLATI VA ISTIQBOLLARI xalqaro ilmiy-amaliy anjumani, 2024-03-20) Shukurov, BegzodVosita deganda qandaydir bir harakatni yuzaga keltirish uchun kerak bo'ladigan jism yoki ularning to'plami tushuniladi.

Sulfur is produced in large quantities in gas processing plants and its rapid availability requires a comprehensive study of this substance and its use in various sectors of the national economy by turning it into environmentally friendly compounds. Purpose of work. Production of sulfur concrete based on melamine and modified sulfur and study of its physical and mechanical properties. Methodology. The microstructure of modified sulfur concretes was studied by SEM and IR spectroscopic methods, thermal characteristics were determined by differential thermogravimetric met hods in the DT-60 device. Originality. A new type of sulfur concrete was obtained based on melamine and modified sulfur; the physical and mechanical properties of the obtained concrete were determined to have high deformation stability and adhesion properties. Findings. Due to the unique structure of the melamine substance and the presence of active functional groups, the formation of a copolymer with modified sulfur showed that it participates as the main binding agent in the production of sulfur concrete.Item type: Item , NEFT MAHSULOTLARINI TOZALASHDA TABIIY SORBENTLARNING OQARTIRUVCHANLIK XOSSASINI О‘RGANISH(QarDU xabarlari, 2023-12-30) G.B.RaxmatovaAnnotatsiya.
