Ligand Effects

To facilitate analysis of nanoscale heat transfer in nanoparticle systems the thermal properties of ligand layers must be understood. To this end, we use an optical pump-probe technique to study the thermal transport across ligands on gold nanorods and into the solvent. We find that varying properties of the ligand can have large impacts on the thermal decay of a nanorod after exposure to a laser pulse. By raising the concentration of free CTAB from 1 mM and 10 mM in solutions, the CTAB layer’s effective thermal interface conductance increases three fold. The transition occurs near the CTAB critical micelle concentration. Similar results are found for other ligand layers.

Wetting Properties

We modify optical and wetting properties of solids using a femtosecond laser surface nanostructuring technique. We demonstrate that this technique allows creating black and color metals. Absorptance of black titanium created in our study is measured to be about 90-97% over a broad wavelength range from the ultraviolet to infrared. Moreover, our technique can be also used for modifying wetting properties of solids. Here, we create a novel surface structure that transforms regular silicon to superwicking. This surface structure makes water run vertically uphill in a gravity defying way. Our study of the liquid motion shows that the extraordinarily strong self-propelling motion of water is due to a capillary effect from the surface structures we created.
