Abstract:
A phase transition composite material (1) includes a dispersion of single-domain magnetic nanoparticles (2) and an elastic encapsulant (3) arranged to separate the nanoparticles (2). The composite material (1) is deformable between first and second states. In the first state the material is relaxed and in the second state the material is stressed. In the first state, the magnetizations of the magnetic nanoparticles (2) are less ordered (e.g., the magnetic nanoparticles (2) exhibit superparamagnetism) and, in the second state, the magnetizations of the magnetic nanoparticles (2) are more ordered (e.g., the magnetic nanoparticles (2) exhibit superferromagnetism or superantiferromagnetism).

Abstract:
Polymer solar cells with enhanced efficiency utilize an active layer formed of a composite of polymer/fullerene and Fe 3 O 4 nanoparticles. During the formation of the solar cell, the composite mixture is subjected to an external magnetic field that causes the nanoparticles to align their magnetic dipole moments along the direction of the magnetic field, so as to form a plurality of Fe 3 O 4 nanochains. These nanochains serve to adjust the morphology and phase separation of the polymer/fullerene, and also serve to induce an internal electrical field by spin-polarization of the nanochains serve to increase the charge separation and charge transport processes in the solar cell, enhancing the short-current density (J sc ) and ultimately, the photoelectric converted efficiency (PCE) of the solar cell.

Abstract:
A material comprising positively and negatively charged nanoparticles, wherein one of said nanoparticles contained a magnetically responsive element, are combined with a support molecule, which is a long natural or synthetic molecule or polymer to make a magnetic nanoparticle assembly. When the magnetic nanoparticle assembly is combined with cells, it will magnetize those cells. The magnetized cells can then be washed to remove the magnetic nanoparticle assembly and the magnetized cells manipulated in a magnetic field.
