报告摘要：

This seminar explores groundbreakingadvances at the intersection of interfacial physics and sustainability. Threerevolutionary systems are unveiled: Droplet mops that remove surfacecontaminants with 99.9% efficiency using raindrop-sized impacts, slashing wateruse by 90% for solar farm cleaning; A self-sufficient air-to-fertilizer systemcombining fog harvesting and droplet-based nitrogen synthesis, boosting cropyields without freshwater or chemical inputs; and An electricity-free air-to-hydrogen technologyleveraging radiative cooling and photocatalysis to produce green H₂ from atmospheric moisture . Together, these innovations harnessnonlinear fluid dynamics, spectral engineering, and environmental resourceharvesting to address water scarcity, food security, and clean energy, aligningwith UN Sustainable Development Goals.
