Abstract: Clean water for drinking and cooking has been a serious issue in rural areas of Vietnam, which is mainly due to high-cost treatment of the available water sources in such areas. In order to decrease the treatment cost, gel-derived Ag-TiO2-SiO2 thin film coated on glass beads were used as disinfection materials under UV-C light in this work. The photocatalyst was used in a continuous-flow lab-scale reactor to disinfect E.coli in water. It was found that the bactericidal activity of this system using the gel-derived Ag-TiO2-SiO2 photoatalyst under UV-C irradiation was superior to those using UV-C irradiation alone, a combination of bare glass beads and UV-C irradiation. By using gel-derived Ag-TiO2-SiO2thin film, the above reactor was observed to remove 6-log of E.coli under UV-C within the hydraulic retention time of 6 minutes.The reactor was also operated with Mekong river water (includes Tien river and Hau river) with the inlet microbial loading of Tien river (after filtering) from 50

Abstract: This paper reviews recent research in the fields of blending natural polymers and synthetic polymer focusing on electrospinning technique for application of tissue engineering. Suitability of developed new synthetic material promotes new live saving potential for patient. Previous research shows that Polycaprolactone (PCL) and Polylactic acid (PLA) have excellent biodegradability and biocompatibility for tissue engineering. However, the lacks of mechanical strength and elasticity makes this polymer unsuitable for engineering vascular scaffolds. Polyurethane has a potential application in tissue engineering. Many researchers actively conduct experiment based on this elastiomer due to its good mechanical testing and elasticity. This review provides information on current research that is useful for the specific application.
