In this study, TiO2 nanoparticles were synthesized by a sol–gel method involving the interaction of the titanium isopropoxide precursor and sodium hydroxide followed by calcination at a temperature of 450 °C. The effects of stirring time and solution pH on the morphology, phase types and crystallite sizes were investigated. The prepared TiO2 nanoparticles were characterized using X-ray diffraction...... hiện toàn bộ

Zinc oxide nanoparticles (ZnO-NPs) of different sizes and morphology were synthesized. The variables analyzed were zinc precursor concentration, the nature of the synthesis solvent and the concentration of surfactant agent. The solids synthesized were characterized using IR spectroscopy, X-ray diffraction (XRD) and transmission electron microscopy (TEM). Considering the nature of the synthesis pro...... hiện toàn bộ
Structurally identified curcumin-Ag/ZnO nanocomposite having antibacterial effect: an investigationInternational Nano Letters - Tập 12 - Trang 243-255 - 2022
Rajender Singh, Ramesh Sharma, Moondeep Chauhan, Dheeraj Sharma
Taking advantage of zinc oxide (ZnO), silver (Ag) and curcumin (Cur) properties, the Cur-Ag/ZnO nanocomposite (CNCs) are reported here. Electron spray ionization mass spectrometry (ESI–MS) confirmed the presence of curcumin mass fragments in the reported CNCs. Further, the existence of keto-enolic state of Cur in CNCs has been confirmed by NMR study. Photoluminescence (PL) and fluorescence microsc...... hiện toàn bộ
