The Ta doped ZnO nanorods (Ta-ZnO) were synthesized by a hydrothermal method at different temperatures (110, 150, and 170 °C) for the photodegradation of methylene blue (MB) under visible light.

Recent research in drug delivery, gelatin stand out from all other natural polymer by its property such as biocompatible, biodegradable, reduced immunogenicity. Modify porous nano silica (PNS) by gelatin to use for drug delivery can avoid the detection of the human immune system. In this study, the coated PNS was successfully formed with spherical shape and diameter around 70 nm determined by transmission electron microscopy (TEM). Drug loading and release behaviors of doxorubicine@PNS-gelatin, in particular, were also tested. This study is expected to improve the stability of PNS for drug delivery system in cancer therapy.

This study is devoted to the synthesis of King Orange peel essential oil in water nanoemulsions combined with nanosilver by ultrasonic method supported by mechanical stirring for antibacterial application. The samples were characterized by Gas chromatography-mass spectrometry (GC-MS), Ultraviolet-visible (UV-Vis), Transmission electron microscopy (TEM), and Dynamic light scattering (DLS) methods. According to the above-experimental results, it was found that the emulsions based on orange essential oil (without nanosilver) and the ones combined with nanosilver have the average particle size from 66.2 nm and 42.9 nm, respectively. The obtained nanoemulsions were also tested to examine their antibacterial ability against Escherichia coli (E. coli) by the disc diffusion method. It has been also found that nanoemulsions based on orange essential oil supported by nanosilver have the superior antibacterial ability, compared with individual components of the materials.
