Super Moisture-Absorbent Gels for All-Weather Atmospheric Water Harvesting.
TL;DR: The synergistic effect enabled by the molecular level integration of hygroscopic and hydrophilicity-switchable polymers in a network architecture presents controllable interaction between the gel and water molecules, simultaneously realizing efficient vapor capturing, in situ water liquefaction, high-density water storage and fast water releasing under different weather conditions.

Water and Metal-Organic Frameworks: From Interaction toward Utilization.
TL;DR: An update on stability of MOFs in water vapor and liquid systems is provided, and a suite of 18 MOFs are identified for selective use in heat pumps and chillers, while several can be used for air conditioning, water harvesting, and desalination.

Four billion people facing severe water scarcity
TL;DR: It is found that two-thirds of the global population (4.0 billion people) live under conditions of severe water scarcity at least 1 month of the year, and nearly half of those people live in India and China.
Journal ArticleDOI
Passive radiative cooling below ambient air temperature under direct sunlight
TL;DR: An integrated photonic solar reflector and thermal emitter consisting of seven layers of HfO2 and SiO2 that reflects 97 per cent of incident sunlight while emitting strongly and selectively in the atmospheric transparency window demonstrates that the cold darkness of the Universe can be used as a renewable thermodynamic resource, even during the hottest hours of the day.
