Biocompatible phosphate materials are used in different applications like bone and dental implants, drug delivery systems others, but could also be applied inorganic sunscreens. Using sunscreens is extremely necessary, because long time exposure to sun can cause skin cancer. In this work chemical precipitation method has been produce hydroxyapatite. Cr3+, Zn2+ Fe3+ doped samples were characterized using powder X-Ray Diffraction (XRD) Optical Absorption techniques. X-ray diffraction...
Ab initio calculations based on density-functional theory have been employed to study structural and electronic properties of Bi4Ge3O12 (BGO) Bi4Si3O12 (BSO), as well their optical characteristics in ultraviolet region, up 40 eV. The structure around the band gap is found be similar both compounds, dominated by O p- Bi s-states (valence top) p-states (conduction bottom). indirect BGO BSO. spectra are analyzed, compared, interpreted terms calculated structures. It shown that absorption...
Purpose: This paper describes a method to achieve consistent clinical image quality in 18 F‐FDG scans accounting for patient habitus, dose regimen, acquisition, and processing techniques. Methods: Oncological PET/CT scan data 58 subjects were evaluated retrospectively derive analytical curves that predict quality. Patient noise equivalent count rate coefficient of variation (CV) used as metrics their analysis. Optimized acquisition protocols identified prospectively applied 179 subjects....
