objective(s): hardystonite (ht) has been successfully prepared by a modified sol-gel method. we hypothesized thatnano-sized (ht) would mimic more efficiently the nanocrystal structure and function of natural bone apatite, owing to the higher surface area, compare to conventional micron-size (ht).materials and methods: the hardystonite nanopowder was prepared via a modified sol-gel method.optimi...

In this project, Bredigite (BG) has been successfully prepared by a modified sol-gel method. Optimization in calcination temperature and mechanical ball milling resulted in a pure and nano-sized powder which characterized by means of X-ray diffraction; scanning electron microscopy, transmission electron microscopy and Fourier transform infrared Spectroscopy. We hypothesized that nano-sized Bred...

The positive effect of Si and Zn ions on bone formation and metabolism has already been confirmed. The aim of this study was preparation and characterization of Willemite (Zn2SiO4) for the repair of bone defects. Willemite was prepared through solid state reaction. Phase analysis and chemical compositions were investigated. The zeta potential of the nanoparticles was determined in physiological...

The effects of black rice powder on the quality of sausage were investigated. Samples were prepared with 0% (control), 1%, 3%, and 5% black rice powder. With increasing black rice powder content, the moisture and ash content of sausage increased, while protein content was significantly less than that observed for the control (p<0.05). The fat content in samples containing 5% black rice powder w...
