Digestion of Ambient Humidity for Energy Generation

Ultrahigh solar-driven atmospheric water production enabled by scalable rapid-cycling water harvester with vertically aligned nanocomposite sorbent

“…Lately, these novel sorbents with high water sorption performance and special thermal/electrical effects also inspired energy-related applications such as energy storage, 22,23 thermal management, [24][25][26][27] electricity/fuel generations, 28,29 or co-application. [30][31][32] The MOF-801-based solardriven SAWH prototype was first reported in 2017 with an all-in-one design by integrating light absorber, sorbent, and condenser in one chamber; 33 afterwards, the SAWH prototype was improved by introducing radiative cooling to promoting the water sorption at nightime. 34 The research team of O.M.…”

Repurposing face mask waste to construct floating photothermal evaporator for autonomous solar ocean farming

“…Aside from the environmental concerns induced by disposable FM, water scarcity is another enormous challenge across the globe as the global demand of clean water keeps increasing dramatically 10 . Solar thermal desalination, which particularly occurs at the seawater/air interface by photothermally converting solar energy into steam generation, has drawn widespread attention as an emerging clean water production technology to mitigate water scarcity 11–17 . Solar absorbing materials positioning at the interface therefore play a critical role in the photothermal conversion process.…”

Reversible Hydration Composite Films for Evaporative Perspiration Control and Heat Stress Management

“…By adding ethanolamine into the zinc chloride aqueous solution at a molar ratio of 1:2, a coordination reaction involving ethanolamine ligands and zinc ions occurs, resulting in the formation of a chelate complex, named Zn-complex ([Zn(NH 2 -(CH 2 ) 2 -OH) 3 ] 2+ ), [26][27][28][29] which is known to have a strong affinity to water molecules in the air due to its low water embedding energy at the molecular level. [30][31][32][33][34] However, the Zn-complex is gel-like with poor mechanical strength (Figure S2, Supporting Information). Due to its non-freestanding behavior, Zn-complex must be attached to or supported by a substrate when used in practical applications.…”
