Nonthermal atmospheric water harvesting
Ultrasound can extract captured water efficiently. How can sorbent uptake and actuation stay coordinated as moisture loading and humidity change?
Water and waste
Harvesting freshwater, preserving salt barriers, destroying persistent chemicals, and sorting layered plastics.

4 problemsMembrane-distillation wetting control
Can seawater distillation membranes stay productive without letting salt water leak through their pores?
Thermal PFAS mineralization
Heating can remove PFAS from waste without fully destroying it. How can thermal treatment prevent incomplete breakdown products and escaping fluorinated vapours?
Multilayer plastic-film sorting
Can waste-sorting systems distinguish different layered plastic films fast enough to route them for recycling?
