香港城市大学Steven Wang教授：Drops of Innovation: Bringing Physics to Sustainable Chemical Engineering

This seminar explores groundbreaking advances at the intersection of interfacial

physics and sustainability. Three revolutionary systems are unveiled:

Droplet mops that remove surface contaminants with 99.9% efficiency using

raindrop-sized impacts, slashing water use by 90% for solar farm cleaning.

A self-sufficient air-to-fertilizer system combining fog harvesting and

droplet-based nitrogen synthesis, boosting crop yields without freshwater

or chemical inputs. An electricity-free air-to-hydrogen technology leveraging

radiative cooling and photocatalysis to produce green H₂ from atmospheric

moisture. Together, these innovations harness nonlinear fluid dynamics,

spectral engineering, and environmental resource harvesting to address

water scarcity, food security, and clean energy, aligning with UN Sustainable

Development Goals.

Prof. Steven Wang serves as the Dean of Engineering, City University of

Hong Kong. He obtained his PhD from Monash University and his Bachelor

of Engineering from The University of Melbourne. Professor Steven Wang

specializes in the synergistic domains of interface engineering and heat/mass

transfer, specifically targeting transformative implications for energy

systems. His work elucidates the complex physical phenomena at phase boundaries

to drive innovation in energy conversion, storage, and sustainability.

Prof. Wang’s scholarly impact is evidenced by his publications in top-tier

journals, including Nature, Nature Physics, Nature Sustainability, Nature

Chemical Engineering, Nature Energy, Nature Synthesis, Nature Communications,

PNAS and Science Advances.
