TL;DR: The design and demonstration of a device based on a porous metal-organic framework that captures water from the atmosphere at ambient conditions by using low-grade heat from natural sunlight at a flux of less than 1 sun (1 kilowatt per square meter).

TL;DR: A metal-organic framework-based water harvesting device that can deliver over 0.25 L of water per kg of adsorbent over a single cycle at relative humidities of 10–40% and at subzero dew points is developed.

TL;DR: In this paper, a mesoporous metal-organic framework that captures 82% water by weight below 30% relative humidity under simulated desert conditions is presented. But the water uptake in this sorbent is optimized: the pore diameter of the material is above the critical diameter for water capillary action, enabling water uptake at the limit of reversibility.

TL;DR: This study demonstrates a viable path to promote cost-effective solar thermal energy at intermediate temperatures by leveraging an artificial greenhouse effect within an optimized monolithic silica aerogel to reduce heat losses while maintaining high solar transparency.

TL;DR: A new multiple-cycle chemical vapor deposition (CVD) method is presented to synthesize horizontally aligned arrays of parallel single-walled carbon nanotubes (SWNTs) with densities of 20-40 SWNT/μm over large area and a diameter distribution of 2.4 ± 0.5 nm on the quartz surface based on a methanol/ethanol CVD method.
