Title: The BAW Based Ultrasonic Manipulation and Fabrication of Micro/Nano Scale Materials

Abstract: Ultrasonic micro/nano manipulation and fabrication is a promising actuation technology, which employs the nonlinear and linear effects of ultrasonic vibration in fluid, solid and gas to implement the manipulation and fabrication of micro/nano scale materials. The nonlinear and linear effects of ultrasound utilized in this technology include the acoustic radiation pressure, acoustic streaming, acoustic cavitation, ultrasonic vibration velocity,  sound pressure, etc. It is has potential applications in biomedical sample treatment, micro/nano fabrication process and chemical reaction catalyses. In this lecture, the bulk acoustic wave (BAW) based micro/nano concentration (enrichment), micro/nano tweezers, nano motors, PM 2.5 sampling from air, removal of micro/nano particles,    gas-molecule-drive derived catalysis effect for the gas-solid interface reaction, and nano gas/strain sensor fabrication, which have been proposed and developed by the speaker’s group in recently years, are presented.  The structures, working principles and characteristics of the ultrasonic devices in these work are demonstrated. The experimental and theoretical work implemented by the speaker’s group, shows that the BAW based ultrasonic methods provide a promising way to handle micro/nano scale samples, to construct high-performance gas sensing systems, and to fabricate high-performance nano-devices.

Title: Additive Manufacturing and intelligent control of high-performance metal materials

Abstract: As an important branch in the field of 3D printing, metals additive manufacturing, has demonstrated great value and broad application in strategic emerging industries such as aerospace like turbo engine and blades, transportation like bearings, new energy and medical structures. The research progress has been made through several decades combined with the lab research. It has changed the traditional manufacturing methods and provided new ideas for the direct manufacturing of complex metal structures and functional parts, liberating the freedom of designers and making new product forms emerge, which shows very considerable prospects in the fields of innovative product development, biomedicine and energy.

Experience: Distinguished Professor of "Hongshen Young Scholars" at Chongqing University, PhD supervisor, assistant chairman of Chongqing Key Laboratory of Metal Additive Manufacturing (3D Printing), director of High-performance intelligent Additive Manufacturing (HπAM) Lab.Dr. Li obtained his Bachelor degree at Jilin University, and obtained Ph.D. degree at Tsinghua University. Then he worked as a postdoctoral scientist at University of Texas at El Paso in USA. In 2019, he served as a senior researcher in the University of Pittsburgh. He is an expert in laser additive manufacturing and materials genome engineering. He has participated in many projects such as National Natural Science Foundation of China, the International Cooperation Projects with US and Singapore. His scientific research achievements won the Researcher Award of the University of Texas and the Houston Space Agency Technology Application Award.
