Advances in harvesting water and energy from ubiquitous atmospheric moisture

Abstract

Sorbent-assisted AWH and moisture-enabled energy generation are reviewed in parallel to reveal the correlation between these two technologies.

Bioinspired topological design with unidirectional water transfer for efficient atmospheric water harvesting

“…5a) by chemisorption. 34,35 Secondly, hydrated CaCl 2 crystals continuously captured moisture to form liquid water droplets around the crystals. The precisely engineered conical channels with This journal is © The Royal Society of Chemistry 2023 spatially centripetal alignment facilitate the transfer of harvested water droplets from the outer side of the hemisphere towards the inner side (where l decreases) by taking advantage of F lap from the asymmetric capillary ratchet effects.…”

Uranium and lithium extraction from seawater: challenges and opportunities for a sustainable energy future

“…267 This indicates that the uranium and lithium concentrations in SWRO brine can potentially reach up to 2.5 times that of seawater without the need for additional energy input and/or capital investment. Second, in the wake of rapid climate change and urbanization, water scarcity is likely to exacerbate, 268,269 which means that the demand for desalination will increase in the coming decades. Today, desalination supplies drinking water to around 300 million people worldwide and produces around 142 million m 3 per day of SWRO brine as a by-product in the process.…”

Self‐Contained Moisture Management and Evaporative Cooling Through 1D to 3D Hygroscopic All‐Polymer Composites

“…As a result, they hold immense promise in various applications including sorption-based atmospheric water harvesting, passive humidity and temperature regulation, protective packaging, sustainable agriculture, and energy generation. [41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57][58] Despite the notable progress, few hygroscopic fibers and fabrics have been fabricated and used as sorption-based cooling textiles for PTM applications. [59,60] Challenges pertaining to the synthesis, modification and related processing techniques can be summarized as follows (i−iii): i) Inherent issues of deliquescence and leaks of hygroscopic salts result in performance decay, skin irritation/corrosion and environmental consequences.…”
