Article Synopsis
- Researchers are tackling the challenge of creating functional materials that direct heat flow in specific ways to improve thermal management.
- They used a technique called spatiotemporally resolved thermoreflectance to study how heat moves in supercrystals made from anisotropic gold (Au) nanocrystals, finding that heat flows more easily along the long axis of these nanocrystals.
- By adjusting the shape of the nanocrystals, they demonstrated increased control over heat directionality, and they used simulations to understand this behavior, offering insights for future applications in thermal management technologies.
Colloidal solutions of gold nanorods and silver-coated gold nanorods were prepared. The seeded growth synthesis protocols were improved by adding a flocculation purification step. The resulting populations of pure gold nanorods and Au@Ag core-shell cuboids were characterized by very low dispersion in size and shape.

Spectrophotometry and inelastic light scattering spectroscopy are noninvasive techniques that are proving highly robust and efficient for characterizing the optical response and vibrational properties of metal nano-objects. Here, we investigate the optical and vibrational properties of monodomain silver nanocubes synthesized by the chemical route, with edge length ranging from around 20 to 58 nm.
