Abstract: 

Nanotechnology holds promise for revolutionizing future industries related to energy, materials, electronics, biomedicine, military, and consumer products. Due to the importance to the future energy and other emerging needs, thermophysical engineering research has been growing especially in the emerging field of micro/nanoscale heat transfer. When the characteristic length becomes comparable to the mechanistic length scale, continuum assumptions that are often made in conventional thermal analyses may break down; similarly, when the characteristic time becomes comparable to the mechanistic timescale, traditional equilibrium approaches may not be appropriate. Understanding the energy transport physics in small dimensions and short timescales is crucial for future advances of nanotechnology. In this presentation, I will review the historical development in nanoscale and microscale thermal engineering, concentrating on heat conduction and thermal radiation. An outline of my Nano/Microscale Heat Transfer book will also be presented. It represents a logical sequence to introduce statistical mechanics, quantum physics, solid-state physics, and electrodynamics, necessary for solving thermal transport problems in nanostructures or during short-pulsed laser heating. Furthermore, I will introduce the recent developments in the field with promising applications.
