5 totalThermal PFAS mineralization
Heating can remove PFAS from waste without fully destroying it. How can thermal treatment prevent incomplete breakdown products and escaping fluorinated vapours?
Electrochemical direct air capture
Electrochemical cells can capture carbon dioxide from air. Can larger stacks sustain that performance while purifying the gas and keeping airflow resistance manageable?
Multilayer plastic-film sorting
Can waste-sorting systems distinguish different layered plastic films fast enough to route them for recycling?
Membrane-distillation wetting control
Can seawater distillation membranes stay productive without letting salt water leak through their pores?
Nonthermal atmospheric water harvesting
Ultrasound can extract captured water efficiently. How can sorbent uptake and actuation stay coordinated as moisture loading and humidity change?
