Abstract:
A superparamagnetic pomegranate-like core@shell structure with Fe(3)O(4)@SiO(2) nanoparticles as cores and cross-linked PZS as shells was fabricated. The Fe(3)O(4)@SiO(2)@PZS hybrid composite shows exellent solvent resistance and water dispersion, allowing potentially great biocompatibility and possible tailored surface chemistry for applications in biotechnology.

01:30Paramagnetism
Paramagnets are materials with unpaired electrons that possess a finite magnetic moment. In the absence of a magnetic field, these moments are randomly oriented, and thus the net moment is zero. Under an external field, a torque acting on the moments tends to align them along the field's direction. However, the random thermal motion of electrons produces a torque opposite to the external field and tries to disorient the moments. These two competing effects align only a few moments along the...
01:31Ferromagnetism
Materials like iron, nickel, and cobalt consist of magnetic domains, within which the magnetic dipoles are arranged parallel to each other. The magnetic dipoles are rigidly aligned in the same direction within a domain by quantum mechanical coupling among the atoms. This coupling is so strong that even thermal agitation at room temperature cannot break it. The result is that each domain has a net dipole moment. However, some materials have weaker coupling, and are ferromagnetic at lower...
