Monodisperse MFe2O4 (M = Fe, Co, Mn) nanoparticles.
As-synthesized iron oxide nanoparticles have a cubic spinel structure as characterized by HRTEM, SAED, and XRD and can be transformed into hydrophilic ones by adding bipolar surfactants, and aqueous nanoparticle dispersion is readily made. Expand
Size-controlled synthesis of magnetite nanoparticles.
The reported procedure can be used as a general approach to various ferrite nanoparticles and nanoparticle superlattices. Expand
Remote control of ion channels and neurons through magnetic-field heating of nanoparticles.
This work shows an approach based on radio-frequency magnetic-field heating of nanoparticles to remotely activate temperature-sensitive cation channels in cells, which triggers action potentials in cultured neurons without observable toxic effects. Expand
Monodisperse MFe 2 O 4 ( M ) Fe , Co , Mn ) Nanoparticles
High-temperature solution phase reaction of iron(III) acetylacetonate, Fe(acac)3, with 1,2hexadecanediol in the presence of oleic acid and oleylamine leads to monodisperse magnetite (Fe3O4)Expand
Structure and magnetic properties of ferromagnetic nanowires in self-assembled arrays
Static and dynamic aspects of the magnetization reversal in nanowire arrays are investigated. The arrays have been produced by electrodeposition of ferromagnetic metals (Fe, Co, and Ni) into porousExpand
A general approach to binary and ternary hybrid nanocrystals.
Multifunctional hybrid nanoparticles that combine magnetic, plasmonic, and semiconducting properties and that are tunable in size and morphology can be realized, as demonstrated for combinations of Au, Fe3O4 and PbS or PbSe. Expand
Strong covalency-induced recombination centers in perovskite solar cell material CH3NH3PbI3.
The results show that, in order to prevent the deep-level defects from being effective recombination centers, the equilibrium carrier concentrations should be controlled so that the Fermi energy is about 0.3 eV away from the band edges. Expand
Recent Progress in Syntheses and Applications of Dumbbell-like Nanoparticles.
The general synthesis of dumbbell-like nanoparticles containing noble metal and magnetic NPs/or quantum dots is described and several exciting application potentials of these nanoparticles in catalysis and biomedicine are highlighted. Expand
Size‐Dependent Chemical and Magnetic Ordering in L10‐FePt Nanoparticles
FePt nanoparticles have great application potential in advanced magnetic materials such as ultrahigh-density recording media and high-performance permanent magnets. The key for applications is theExpand
Exchange-coupled nanocomposite magnets by nanoparticle self-assembly
The fabrication of exchange-coupled nanocomposites using nanoparticle self-assembly with an energy product that exceeds the theoretical limit of 13 MG Oe for non-exchange- coupled isotropic FePt by over 50 per cent is reported. Expand
