Abstract:Nano-bioactive glass (NBG) was prepared via sol-gel method and freeze-dried technique using polyethylene glycol (PEG) as templates. The influences of molecular weight and content of polyethylene glycol on the morphology and the size NBG particles were investigated. The optimal sintering temperature of NBG was determined by using thermal gravimetric (TG) and differential thermal analysis (DTA), and the NBG particles were characterized by Fourier-transformed infrared (FTIR) spectroscopy, transmission electron mi… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
