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.

Empathy is not only a vital emotion in interpersonal relationships, but also a core component of social consciousness, culture, and interpersonal intelligence. The student age is a particularly active period for the development of this ability. A pressing issue today is the low level of empathy among students and the need to develop effective psychological approaches to enhance it.

Hozirgi vaqtda ion implantatsiya usuli materiallarning sirt xususiyatlarini maqsadli o'zgartirishning keng qo'llaniladigan usullaridan biridir. Ion implantatsiyasini qo'llashning asosiy sohasi yarimo'tkazgich kristallariga aralashmalarni kiritishdir. Ushbu maqolada Kremniy kristallini Bor bilan implantatsiya qilgandan keyingi strukturasining eksperimental tadqiqotlari natijalari keltirilgan. Yorug`likning kombinatsion sochilishi usulining yarimo'tkazgich kristallarining sirt tuzilishidagi buzilishlarga yuqori sezgirligi ko'rsatilgan. Spektrometr yurug`likning kombinatsion sochilish spektroskopik metodi yoki Romanov spektroskopiyasiga asoslangan.

Атрофдаги оламни билиш - унинг моделларини яратишдан иборат. Улар ушбу олам объектлари билан бизнинг ўзаро таъсиримиз оқибатларини кўриш имконини беради. Моделларни яратиш инсон тафаккурининг ташкилий тузилишини такомиллаштириш жараёни ҳисобланади. Мазкур психологик ташкилий тузилиш мақсадга йўналган ҳаракатлар кўринишида моддийликка айланади, уларни инсон ўзида мавжуд моделлар асосида амалга оширади. Ушбу мақолада математик моделлаштиришнинг асосий масалалари ҳақида фикрлар ёритилган.

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.
