Speech Title: The Bulk Acoustic Wave (BAW) Based Ultrasonic Micro/Nano/Molecular Actuation and Its Application

Abstract: The bulk acoustic wave based ultrasonic micro/nano/molecular actuation is a promising technology, which employs the nonlinear and linear effects of ultrasonic vibration in fluid, solid and gas to implement the manipulation, fabrication and drive 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 has potential applications in biomedical sample treatment, micro/nano fabrication process, chemical reaction catalysis, etc. In this lecture, the 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 enhancement effect for the gas-solid interface reaction, nano gas/strain sensor fabrication, and high-performance ultrasonic cooling devices, 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 works 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.

Speech Title: Advances in Adaptive Machining of Large Complex Thin-wall Parts

Abstract: Large complex thin-wall parts, such as engine casing, blades, aerospace and structural parts, are characterized by thin walls, complex profile, large material removal and high requirements for precision and surface integrity. These key parts are widely used in various fields, where the machining quality and precision directly impact the performance, reliability and service life of equipment. Focusing on the difficulties of high-performance precision machining for large-scale complex thin-wall parts, this report presents recent research advances in multi-constraint motion planning of multi-axis machining, machining dynamics modeling and stability improvement, machining contour error control and online machining status monitoring.
