Advanced Nanostructured Thermoelectric Materials for Waste Heat Recovery
Department of Chemical Engineering
The rapid development of thermoelectric materials in the past decade has provided a possibility of directly converting waste heat back to electricity based on the Seebeck effect. In the past three years, we have developed a transformative approach to pioneered low cost and scalable solution-phase growth methods to mass produce thermoelectric nanowires and nanowire heterostructures to match the physical and economic magnitudes of energy use and economical entertainment in the manufacture/recycling. These nanostructured thermoelectric materials show a significantly enhanced performance compared to the bulk crystals based on the quantum confinement and energy filtering.
About the Speaker
Prof. Wu received his PhD degree from Harvard University under the supervision of Prof. Charles M. Lieber in 2006 and worked with Prof. Paul Alivisatos between 2006 and 2009 as a Miller Research Fellow at University of California at Berkeley. He joined the School of Chemical Engineering at Purdue University in 2009. Currently, his research focuses on the investigation of broadly-defined nanostructured materials for their potential applications for energy conversion and storage, including photovoltaic solar cells, thermoelectrics, and batteries. Prof. Wu has extensive experience in nanomaterials synthesis, assembly, characterization, and device fabrication. Since year 2000, he has published 38 peer-reviewed articles with a personal H-index of 20 and the publications have been cited ~3900 times. Particularly, his group has developed the chemical synthetic methods to grow molecular-scale chalcogenide nanostructures for thermoelectric applications. His research has been featured in Chemical and Engineering News, MRS Bulletin, Nature magazine, Materials Today magazine, Technology Review, National Public Radio (NPR), National Science Foundation (NSF), etc.
