Rux oksidi nanokristallari mufel pechida 500 oC haroratda 1 soat qizdirilganda ularning tashqi sirtida diametri ~100 va chuqurligi ~30 nm atrofida bo‘lgan konussimon shakldagi chuqurchalar paydo bo‘lishi aniqlangan. Yuqori haroratda qizdirish natijasida sintez qilingan ZnO nanokristallarining kristallik darajasi va optik sifati sezilarli darajada pasayishi ko‘rsatilgan.

In this work, we studied the conditions for global solvability and unsolvability of a nonlinear filtration problem with a source and with a nonlinear boundary flow. The critical exponent of the global existence of the solution and the critical exponent of the Fujita type of the problem of nonlinear filtration in an inhomogeneous medium are established. An asymptotic representation of a compactly supported solution is obtained, which makes it possible to carry out a numerical experiment.

Today, the issue of video data processing is very urgent. For example, determining the purpose of human behavior, analyzing economic networks, identifying and eliminating traffic jams on the streets, etc. Nowadays, the increase in the number of vehicles moving on the roads creates traffic jams on the city streets. This makes it urgent to eliminate traffic jams, especially in tourist cities. First of all, the causes of traffic congestion should be identified, traffic congestion can have various causes, such as insufficient capacity, unrestricted demand, traffic light delays, pedestrians crossing the roads at the wrong place , wrong location of sidewalks and etc. Therefore, there is a need to simulate and optimize traffic control to better meet this growing demand. In this research paper, microscopic and macroscopic traffic flow models are reviewed and their properties are discussed to determine which one is suitable for use in this study.

In this work, high-performance CdS, CdSe and CdSe/ZnS nanocrystals with good luminescence were colloidally synthesized at high temperature and incorporated into micrometer-sized polymethylmethacrylate (PMMA) spheres formed by suspension polymerization reaction. CdS, CdSe and CdSe/ZnS quantum dots obtained by the colloid method were stabilized with oleic acid and their optical properties were studied. It was observed that the intensity peaks of quantum dots did not change after modification to PMMA polymer.
