Cooling of nanoparticles
The heat radiation emitted by a nanoparticle depends strongly on its environment. As for the spontaneous emission of atoms, the heat radiated by a nanoparticle changes tremendously when placing it close to a cold surface. This effect is due to the nearfield interaction between the nanoparticle and the surface. This nearfield interaction is sensitive to the geometry of the particle (that is, whether its shape is rice cornlike or pancakelike) and to that of the surface (also including surface roughness). In addition, it turns out that manyparticle effects (configurational resonances) affect the heat flux between nanoparticles. For instance, the radiative heat flow between two nanoparticles can be controlled (increased and decreased) by introducing a third nanoparticle, due to such configurational resonances.
