Nanosized Ag and CeO2 particles obtained through the hydrothermal method were physically mixed to obtain composite antibacterial agents. The comparative experiments of properties showed that activity nanocomposites was improved compared nanoparticles alone, which indicated synergistic effect existed between CeO2. On one hand, ICP-MS results existence suppressed silver ion release rate provided ...

We report a novel template method for synthesizing silica nanoparticles that are mesoporous as well biocompatible. The were synthesized using the Stober process and peptization method. have used surface-modified deoxyribonucleic acid (DNA) with cetyl trimethyl ammonium bromide capping agent. obtained particles analyzed x-ray diffraction, UV–vis spectroscopy, Brunauer–Emmet–Teller method, scanni...

We have developed magnetically modulated optical nanoprobes ~MagMOONs! to magnetically modulate the signal from fluorescent probes and thus separate it from autofluorescence, electronic offsets, and other background signals. These microand nanosized particles emit fluorescence signals, indicating chemical concentrations, and blink in response to rotating magnetic fields. Demodulating the signal...

Fast lithium ion and electron transport inside electrode materials are essential to realize its superb electrochemical performances for lithium rechargeable batteries. Herein, a distinctive structure of cathode material is proposed, which can simultaneously satisfy these requirements. Nanosized Li3V2(PO4)3 (LVP) particles can be successfully grown up on the carbon nanofiber via electrospinning ...

We provide experimental evidence that changes in the membrane fatty acid profile of Tetrahymena thermophila incubated with nano- or bulk TiO(2) particle are not accompanied by ROS generation or lipid peroxidation. Consequently these changes are interpreted as acclimation to unfavorable conditions and not as toxic effects. T. thermophila cells were exposed to TiO(2) particles at different concen...

Nanostructured materials are not immune from surface segregation, as can be shown for solid samples made from nanosized BaFelz.2xCoxTix019 barium femte particles and a variety of free clusters. Both theory and experiment provide ample demonstration that very limited dimensions of very small clusters does not necessarily impart stability against surface and grain boundary segregation. In fact, w...

We identify contributions to the valence band of the nanosized BaFe12−2xCoxTixO19 barium ferrite particles, from the cobalt and titanium dopants. Resonant photoemission results show that cobalt and titanium dopants strongly hybridize with the barium ferrite matrix. Fano resonances are identifi ed in the valence band region, at the Ba (5s), Ti (3p) and Co (3p) thresholds, and there are signifi c...
