Dissipating the ever-increasing heat from electronics requires developing materials with high thermal conductivities. Tervo et al. found, through a series of experiments, that packed silica nanoparticle beds coated with different coolant fluids have greatly enhanced thermal conductivity. The increase may be due to the surface properties of the nanoparticles, which are driven by strong surface electrical polarization. This new approach for modulating thermal conductivity presents new opportunities for thermal management.
