we report the direct soft chemical synthesis and characterization of a family of face centered cubic (fcc) and partially ordered face centered tetragonal (fct) fept nanoparticles (nps) suitable for biomedical applications. both fcc and partially ordered fct-fept nps are synthesized by employing a simple polyol method. by using polyvinyl pyrolidone (pvp) as a stabilizer in various ratios during ...

a new approach for the synthesis of prussian blue nanoparticles using the cationic surfactant cetyl pyridinium chloride (cpc) as capping agent has been developed in the present work. powder x-ray diffraction, transmission electron microscopy, uv–vis absorption spectra, and ir spectroscopy were employed to characterize the product. the tem image showed that the prussian blue nanoparticles with d...

purpose: to report the confocal microscopic features of endothelial vacuolation in donated corneas and to confirm the observed changes by transmission electron microscopy. methods: confocal and transmission electron microscopy were performed on donated corneas with endothelial vacuole formation on slitlamp biomicroscopy. the ultrastructural findings were also compared with those of a normal-loo...

high purity lead titanate nanopowders in tetragonal form have been successfully prepared bycitric acid gel method using lead nitrate and tetra-n-butyl titanate as pb and ti sourcesrespectively and citric acid as complexing reagent. the precursors were calcined at varioustemperatures ranging from 450 °c to 600 °c for 2 h. fourier transform infraredspectroscopy (ft-ir), x-ray diffraction (xrd) an...

in the present work, we report a suitable approach for the preparation of batio3 nanostructures via the hydrothermal condition using dolapix et85 as surfactant. the powders were investigated by x-ray diffraction (xrd), scanning election microscopy (sem), energy-dispersive x-ray spectroscopy (edax), field emission transmission electron microscopy (fetem), selected area electron diffraction (saed...
