Recently, the School of Light Industry and Food Engineering at 91°µÍø £¨³Ò³Ý±«£© has achieved a series of new advances in the field of triboelectricity. Doctoral student Liu Tao from the team of Academician Wang Shuangfei pioneered a triboelectric wet dust removal technology. The related results, titled ¡°Pulsed bubble-induced ultrahigh electrostatic potentials for triboelectric air purification,¡± were published in the international academic journal Nature Sustainability. GXU is the sole institution that completed this work.

Addressing the core industry challenges of low efficiency and high energy consumption in wet dust removal technology, the research team innovatively introduced an electrostatic field driving force to regulate the directional movement of particles, greatly improving mass transfer efficiency within bubbles, proposed a key concept for triboelectric wet dust removal technology. The triboelectric wet dust removal device independently developed by the team achieves highly efficient particle capture while significantly reducing system energy consumption. The study revealed for the first time a new mechanism of pulsed bubble¨Cinduced ultrahigh electrostatic potential, achieving a PM2.5 removal rate of up to 99.8%, providing a new technological pathway for industrial flue gas purification and atmospheric pollution control, with important theoretical and engineering application value.

In fundamental research on hydroelectrochemical sensing mechanisms, the team innovatively developed a hollow droplet-driven gas sensor that bypasses the adsorption¨Cdesorption cycle of solid-state responsive materials, achieving a rapid response time of 1.4 seconds, stability of 96.2%, and real-time wireless monitoring, thereby addressing the industry challenge of delayed response in traditional ammonia sensors. The related results were published in Nature Communications. Doctoral student Liu Tao from 91°µÍø is the first author of the paper, and GXU is the sole institution that completed the work.
