Abstract:
Magnetic Hydroxyapatite (HAP) particles were successfully synthesized at different concentration of Fe2+ by a co-precipitation method. The influences of concentration of doped ions and calcination temperature on the morphology and magnetic property were studied. The iron ions-doped HAP still kept its structure similar to conventional HAP and no second phases were detected. Results indicated that the doping of iron ions decreased the crystallinity and inhibited the c-axis growth and promoted the a-axis growth. HAP particles incorporated with 10% and 50% iron ions exhibited superparamagnetic and with 30% iron ions exhibited weak ferromagnetic characters. In addition, calcination temperature also increased the remnant.

Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
03:02Colors 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 eye.
