Abstract:Hydroxyapatite (HAp), Ca 10 (PO 4 ) 6 (OH) 2 , is known to precipitate on bioactive materials such as TiO 2 and CaTiO 3 by soaking in simulated body fluid (SBF). The formation of HAp on TiO 2 surfaces under continuous ultraviolet (UV) irradiation was investigated. Anatase-type TiO 2 film was synthesized on pure Ti substrates by a combined chemical-hydrothermal treatment. The specimens were immersed in SBF in darkness or under UV irradiation with a centered wavelength of = 365 nm. Under dark conditions, a thi… Show more
scite is a Brooklyn-based startup 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 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.
