- •
Size and oxidation greatly influence the specific heat of metallic nanoparticles.
- •
Specific heat of nanoparticles can be 1 time larger than that of bulk.
- •
With only size effect considered, specific heat can be increased by 1.25 times.
- •
Oxidation has a more important effect than size on the specific heat of nanoparticle.
- •
Thermal conductivity (TC) of nanoparticle tablet can be smaller than 10% of bulk TC.
