Abstract:
Fe3N submicrorods with desirable magnetic properties were prepared from a designed metal-organic framework precursor via a modified ethanediamine nitridation route. Magnetic resonance imaging using the Fe3N submicrorods was investigated carefully, confirming the Fe3N submicrorod could be acceptable as a significant contrast agent for its outstanding concentration dependent signal and high r2 relaxivity. Besides, the excellent saturation magnetization and homogeneous dispersity also developed the Fe3N application range.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
