Advanced materials have been of interest in recent years because of their outstanding properties that bring many useful applications to humans, they can be highly compatible with alternative materials. In particular, coating materials on HAp base increase the biocompatibility of HAp. In this study, we synthesize TiO2/HAp composite materials using the sol - gel method. Samples were made under different synthesis conditions in terms of HAp/TTIP ratios: (1:1); (1:1.5); (1:2); (1:2.5); (1:3). Factors affecting the synthesis process, such as the incubation time and pH of the solution, were also investigated. The optimal conditions for the synthesis process are the ratio HAp/TTIP: 1 gram HAp with 2 ml TTIP; stirring time: 16 hours; pH of the gel solution: pH = 0.5, as determined from the analysis of the X-ray diffraction spectrum and SEM surface morphology. The research results are the basis for research on biomedical materials.

In the trend of globalization and international integration of our country today, learning foreign languages in general and English in particular are aimed at achieving communication purposes. Therefore, learning the linguistic knowledge including vocabulary is also for the purpose of developing learners' communication skills. The non-majored English training for students at the Foreign Language Center - Thu Dau Mot University is directed to the effectiveness of communication, the most prominent is the method of learning vocabulary through the application of Morphology and Morpheme; At the same time, the method of learning meanings of words in the context and application of newly-learned words in the practice of communication skills will be also focused.
