Abstract:
... Recent researches have demonstrated sorption-based atmospheric water harvesting (SAWH) as a sustainable, energy-efficient, and low-cost strategy to alleviate the water crisis. But the low daily water productivity of devices (L/kg day⁻¹) remains a bottleneck to achieve efficient water production as they are merely allowed for intermittent operation. This limitation makes it rather challenging to de ...
