This study investigates the utilization of nano-composite hydrogels for the removal of methyl violet from aqueous solutions, leveraging a Fenton-like reaction mechanism. The nano-composite hydrogel demonstrated exceptional efficiency in dye removal, attributed to the synergistic effects of the hydrogel matrix and the catalytic activity of embedded nano-particles. This process generates hydroxyl radicals under mild conditions, leading to the effective breakdown of various industrial dyes. The kinetics of dye removal, the reusability of the nano-composite, and the influence of operational parameters such as different amounts of nano-composite, pH, , temperature, and dye concentration were systematically explored. The findings underscore the potential of nano-composite hydrogel as a promising, environmentally friendly solution for wastewater treatment and dye removal.

In our study, we examined white laboratory rats born from control and experimental mothers with hypothyroidism. As a result of morphological analysis of the pancreas in different periods of postnatal ontogenesis, significant changes in the delay in the development and formation of individual components of the vascular wall were revealed compared to the control group. From the first days after the start of the experiment, changes in the arterial wall were noted in all experimental animals. The results show that morphological changes in the cells of the pancreas and its blood vessels occur in the offspring born from mothers with hypothyroidism.

Reading plays a vital role in English language acquisition as it helps learners improve vocabulary, grammar, and comprehension skills. Through reading, students are exposed to various sentence structures, idiomatic expressions, and contextual usage of words, which enhances their language proficiency. It also increases motivation and interest in learning, especially when learners choose materials that match their interests and level. Reading not only develops language input but also supports other language skills such as writing and speaking. Furthermore, it encourages independent learning and critical thinking. Effective reading strategies and regular reading habits can significantly speed up the process of acquiring English. Therefore, reading is considered one of the most effective and accessible tools in second language learning.
