报告题目：Nanoengineering for Advanced Materials & Structures: Thermal, Electrical and Mechanical Behaviors
报告人：Dr. Yanguang Zhou（University of California Los Angeles）
When the scale of materials goes down to a tiny scale, i.e., nanometer scale which is a billionth of a meter, the physical and chemical properties of the materials become quite unusual due to the quantum and size effects. As a result, nanotechnologies have often served as tools for design of highly functional engineered materials & structures with potential applications in health, energy and manufacturing. In this seminar, I will discuss a number of nanoengineering examples showcasing our recent materials and technologies innovations including the active control of heat conduction using magnetic controllable thermal conductivity, boosting the thermoelectric performance via decoupling the thermal and electrical transport, and interfacial absorption for the morphology of graphene on the substrate. I will introduce a new methodology to handle the thermal transport process in magnetic semiconductors & insulators, demonstrate how the nanotwinned structures can improve the electrical properties, and propose a criterion on the morphology of graphene in graphene-based composites. Future research on wearable thermoelectric generator, magnetic materials for smart materials, and interfacial thermal management for heat dissipation in chips and water treatment, i.e., water desalination and water purification, will be also discussed.
