The evolution of size and size distribution during hydrothermal synthesis of nanocrystalline CoFe2O4 has been studied by in situ synchrotron powder X-ray diffraction (PXRD). Varying synthesis temperature or [OH(-)] concentration in the precursor proves to have no significant effect on the final volume-weighted nanocrystallite sizes (∼12 nm) of CoFe2O4. However, analysis by whole powder pattern ...

Nearly monodisperse cobalt ferrite (CoFe2O4) nanoparticles without any size-selection process have been prepared through an alluring method in an oleylamine/ ethanol/water system. Well-defined nanospheres with an average size of 5.5 nm have been synthesized using metal chloride as the law materials and oleic amine as the capping agent, through a general liquid–solid-solution (LSS) process. Magn...

This study describes a new strategy toward the development of advanced immunosensors based on chemically functionalized magnetic-core/porous-shell CoFe2O4/Cu2O composite nanoparticles, and the preparation, characterization, and measurement of relevant properties of the immunosensor useful for the detection of hepatitis B surface antigen (HBsAg) in clinical immunoassay. The immunosensor based on...

Three-dimensional printing is one of the most promising areas additive manufacturing with a constantly growing range applications. One current tasks development new functional materials that would allow manufacture objects defined magnetic, electrical, and other properties. In this work, composite magnetic filaments for 3D tunable properties were produced from polylactic acid thermoplastic poly...

We discuss the atomic structure of cobalt ferrite nanoparticles doped with Mn via an analysis based on combining pair distribution functions high energy X-ray diffraction and high-resolution transmission electron microscopy measurements. Cobalt are promising materials for metal–air battery applications. ferrites, however, generally show poor electronic conductivity at ambient temperatures, whic...

Abstract The beneficial combination of micro- and nano-patterned surfaces with magneto-optical materials was investigated over the recent years. Due to their resonant behavior, these structures are commonly used enhance non-reciprocal effects. In this paper, a novel kind intensity effect is enhanced an all-dielectric grating patterned on magnetic nanocomposite layer. This latter formed by CoFe2...
