Core Shell Structure

The core–shell structure greatly suppressed the shuttle effect of the lithium–selenium battery and the robust carbon shells could remain unbroken even after 100 cycles and flexibly accommodate to the volume change of selenium cores.

PtPd@Pt core-shell ultrathin nanowires were prepared using a one-step phase-transfer approach. The diameters of the nanowires range from 2 to 3 nm, and their lengths are up to hundreds of nanometers. Line scanning electron energy loss spectra showed that PtPd bimetallic nanowires have a core-shell structure, with a PtPd alloy core and a Pt monolayer shell. X-ray absorption near edge structure (XANES) spectra reveal that a strong Pt-Pd interaction exists in this nanowire system in that there is PtPd alloying and/or interfacial interaction. Extended x-ray absorption fine structures (EXAFS) further confirms the PtPd@Pt core-shell structure. The bimetallic nanowires were determined to be face-centered cubic structures. The long-chain organic molecules of n-dodecyl trimethylammonium bromide and octadecylamine, used as surfactants during synthesis, were clearly observed using aberration-corrected TEM operated at 80 KV. The interaction of Pt and surfactants was also revealed by EXAFS.

AbstractAbstract We report a one-step hydrothermal synthesis of Fe3O4 nanoparticles coated with Polyethyleneglycol (PEG). The formation of the Fe3O4 core and the polymer coating took place simultaneously. Fe3O4/polyethylene glycol (PEG) magnetic nanocomposite with a core-shell structure with a 17±7 nm crystallite size prepared by simple hydrothermal method. VSM ( Vibrating Sample Magnetometer) analysis proved the superparamagnetic character of the nanocomposite. Graphical abstract
