bioactive materials including glass and glass-ceramics are nowadays used as medical implants for orthopedic applications. in this study several samples of glass-ceramics have been prepared using both heat treatment and sol-gel processes. the structure and bioactivity of these samples based on their interaction with simulated body fluid (sbf) have been determined. in-vitor, using the raman spect...

the mössbauer spectra of nanoferrite materials such as ni0.25mn0.75fe2o4, co0.5mn0.5fe2o4 and ni0.4co0.6fe2o4 have been reported and the above materials were prepared by sol-gel combustion method using metal nitrates as source material and polyvinyl alcohol(pva) as agglomeration reducing agent. as the structural, thermal and magnetic properties (vsm) of the above ferrites have been published al...

context this study aimed to provide an overview of the literature on the radiopacity of dental materials in order to emphasize its importance. evidence acquisition english-language literature was investigated using manual and electronic searches for the terms “radiopacity,” “dental material,” “cement,” “composite,” “ceramic,” “endodontic root canal sealer,” “bone graft,” and “acrylic resin” in ...
