Heavy metals contamination is a serious threat to all life forms. Long term exposure of heavy metals can lead to different life-threatening medical conditions including cancers of different body parts. Phytoremediation and bioremediation offer a potential eco-friendly solution to such problems. Different microbes can interact with heavy metals in a variety of ways such as biotransformation, oxidation/reduction, and biosorption. Phytoremediation of the heavy metals using plants mostly involves rhizofilteration, phytoextraction, phytovolatization, and Phyto stabilization. A synergistic approach using both plants and microbes has proven much more efficient as compared to the individual applications of microbes or plants. This article aims to highlight the synergistic methods used in bioremediation, emphasizing the potent collaboration between bacteria and plants for environmental cleaning, along with the discussion of the importance of site-specific variables and potential constraints. While identifying the necessity for all-encompassing solutions, this review places emphasis on the combination of methodologies as a multifarious rehabilitation approach. This discussion offers insightful suggestions for scholars, scientists and decision-makers about the sustainable recovery of heavy metal-contaminated environments using a comprehensive strategy.

In this study, we synthesized graphene oxide (GO) by modified low temperature Hummer’s method and in situ hydrothermally grown TiO­2 nanotube (TNT) onGO sheet. Transmission electron microscopic (TEM) images showed the homogeneous formation of TNT with the mean diameter of ~8 nm and the co-existence of TNT and GO in the composite sample. X-ray differaction pattern of GO indicated the successful fabrication. The UV-vis measurement with methylene blue indicated the improvement of physical adsorption of the composite samples.

The purpose of the article is to study the presentation of traditional Chinese music genres in the world. The methodology of the study is to use historical and biographical methods in the study of this topic. The scientific novelty of the article is to explore the expediency of presenting traditional Chinese music genres in the world. After all, this question reflects both the traditions and customs of the country and raises the names of scholars of Chinese culture. The presentation of Chinese art is due to the holding of opera festivals that influence the culture of the whole country. The emergence of new theatrical acts and performances also influenced China's outlook. Conclusions. The introduction of traditional Chinese music genres in the world is due to the development of culture and education in the country. The system of thinking of Chinese culture is based on the ancient philosophy of the country. Musical art is in constant search: the nature of sound, timbre palette, forms, combining national motives. Through the combination of national traits, country philosophy, religious tendencies, elements of vocal and instrumental folklore, theater and composition, and piano culture, China's musical piano culture has become well-known in the world. It was the Suetan School and Yuege's educational system that formed the basis for the development of Chinese musical culture. Speaking about the nature of Chinese music, it should be emphasized that it has its intonation-melodic nature, which is different from European music samples. Chinese people became acquainted with the performance of European works through touring. In the early ’70s began to reform the conservatories into musical institutes. For example, music institutions such as the conservatories in Wuhan (Hubei), Shenyang (Liaoning), Xi'an (Shaanxi), and Chengdu (Sichuan) have undergone these changes. During this period (the ’70s), the flowering of Chinese music education began, orchestras, amateur bands appeared, research aroused curiosity, and music magazines began to be published. Teachers such as Zhou Xiaoyan, Lan Yushu, Yu Yixuan, Shen Xiang, Xi Ggui, Wen Quecheng, Li Zhishui, Wei Chixian, Man Jiangxi, Sung Xin, Hu Yan, Gao Zhilan, Do Shinji, and others start their creative activity. The revitalization of music education is in the twentieth century, which causes the development and rethinking of new turns in educational processes. The processes of formation and development of the Chinese music education system are reflected in the works of Wang Yuhe, Liu Pei, Yang Bohua, stylistic features of musical art were interested in F. Arzamanov, V. Vakulishin, Lin Hai, Liu Da-jung, Ma Gesun, Sun Tsunin, In Gen- Ira, Chang Ling, Yang Xiao Xu and more. Chinese education has interested such scholars as: Ding Yun, Yang Bohua. It should be said that much attention was paid to education, as evidenced by the work of scientists. Turning to the historical facts, it becomes known that music education began to develop during the Tang era (VII-X centuries). This led to the emergence of performing schools and the establishment of educational institutions, which allowed to expand the representation of traditional genres of the world.

Graphene-based composites have received a great deal of attention in recent year because the presence of graphene can enhance the conductivity, strength of bulk materials and help create composites with superior qualities. Moreover, the incorporation of metal oxide nanoparticles such as Fe3O4 can improve the catalytic efficiency of composite material. In this work, we have synthesized a composite material with the combination of reduced graphene oxide (rGO), and Fe3O4 modified tissue-paper (mGO-PP) via a simple hydrothermal method, which improved the removal efficiency of the of methylene blue (MB) in water. MB blue is used as the model of contaminant to evaluate the catalytic efficiency of synthesized material by using a Fenton-like reaction. The obtained materials were characterized by SEM, XRD. The removal of materials with methylene blue is investigated by UV-VIS spectroscopy, and the result shows that mGO-PP composite is the potential composite for the color removed which has the removal efficiency reaching 65% in acetate buffer pH = 3 with the optimal time is 7 h. Keywords Graphene-based composite, methylene blue, Fenton-like reaction.
