Ferrofluids prepared by dispersing superparamagnetic Fe3O4@C core–shell nanoparticles in water exhibited exceptional enhancement in thermal conductivity without an external magnetic field.
Stable Ag@graphene oxide nanocolloid (GON) core–shell nanoparticles were synthesized by photochemical reaction.
High quality β-NaGdYF4:Yb/Er and high quantum yield β-NaGdF4:Yb/Er@β-NaYF4 core shell nanoparticles were synthesized.
