报告摘要：
Nanoscale energy, charge and mass transport playscritical roles in various phenomena in nature and has important engineeringimplications. In this talk, I willdiscuss some new understandings we obtained in nanoscale transport and theirengineering applications. For energytransport, I will present a few interesting observations on phonon transportthrough individual nanostructures and their contacts. More specifically, I will show how kinkscould affect the thermal conductivity of boron carbide nanowires, whichprovides new insights into tuning thermal properties ofnanowires/nanomeshes. I will alsointroduce the intriguing diameter dependence of contact thermal conductancebetween individual multi-walled carbon nanotubes, which comes from complexinterplay between phonons and boundaries. Moreover, I will show a distinct signature of electron and phononinteractions in the lattice thermal conductivity of NbSe3 nanowires,which addresses a long-standing, fundamental question of whether and howelectron-phonon interactions affect phonon transport. In terms of charge and mass transport, I willpresent a new approach taking advantage of the superior electronic transportproperties of graphene to probe the electrical activities of individualdendritic spines and synapses of central nervous system neurons cultured inmicrofluidic platforms.
