Content abstract: 
The idea of using light or lasers to drive objects is as inconceivable as the scenes from science fiction movies, and using lasers to drive macroscopic liquid flows is also a major challenge in scientific research. In 2017, Professor Wang Zhiming's team used a pulsed laser to incident a cuvette containing an aqueous solution of gold nanoparticles to achieve a continuous high-speed water jet of up to 4 cm/s in the water. Using the metallic nanoparticles in the technique, which is called the "secret recipe, " the team linked two mechanisms, the photoacoustic effect and the Acoustic wave-driven fluid effect. Therefore, a new mechanism of optically controlled hydrodynamics is proposed.

 

Expert introduction:
WANG Zhiming, professor and doctoral supervisor of the Institute of basic and frontier research, University of Electronic Science and Technology of China. He received his Ph. D. from the Institute of Semiconductors, Chinese Academy of Sciences in July, 1998. He worked as a postdoctoral researcher at the PDI Institute of Solid-State Electronics from August, 1998 to May, 2000. He was a research professor at the University of Arkansas from June 2000 to August 2007. He has been engaged in the growth and characterization of Compound semiconductor nanomaterials, the design and fabrication of prototype optoelectronic devices, and has made a series of innovative research achievements. His papers have been collected in more than 160 papers by SCI, and the results have attracted extensive attention of international peers and professional media. Among them, the pioneering research results of the multi-layer ordered self-organization of strain quantum dots, the control of high index surface nanostructures, and the growth of droplet epitaxial nanomaterials have made important contributions to deepening the understanding of quantum confinement structure and function in the international academic community.
