Progress and Expectation of Atmospheric Water Harvesting
TL;DR: In this article, the fundamental limits of atmospheric water harvesting that can be achieved in typical arid and semi-arid areas were identified and evaluated, and the authors clarified their perspectives on how to search for a simple, scalable, yet cost-effective way to produce atmospheric water for the community.

Tuning Superhydrophobic Nanostructures to Enhance Jumping-Droplet Condensation
TL;DR: It is revealed that properly designed nanostructures should enable nanometric jumping droplets, which would further enhance jumping-droplet condensers for heat transfer, antifogging, and antifrosting applications.

Liquid-Vapor Phase-Change Heat Transfer on Functionalized Nanowired Surfaces and Beyond
TL;DR: An overview of liquid-vapor phase-change heat transfer enhancement on functionalized nanowired surfaces, as well as other promising strategies and surfaces can be found in this article.
Journal Article
Condensation on Slippery Asymmetric Bumps
TL;DR: A conceptually different design approach is presented—based on principles derived from Namib desert beetles, cacti, and pitcher plants—that synergistically combines these aspects of condensation and substantially outperforms other synthetic surfaces.
Journal ArticleDOI
Supramolecular silicone coating capable of strong substrate bonding, readily damage healing, and easy oil sliding.
TL;DR: Damage-healable, oil-repellent supramolecular silicone (DOSS) coatings to harvest abovementioned properties by molecular engineering siloxane oligomers that can self-assemble onto coated substrates via multivalent hydrogen bonding are developed.

Water capture by a desert beetle
TL;DR: It is shown that these large droplets form by virtue of the insect's bumpy surface, which consists of alternating hydrophobic, wax-coated and hydrophilic, non-waxy regions, and may find application in water-trapping tent and building coverings, for example, or in water condensers and engines.
Journal ArticleDOI
Directional water collection on wetted spider silk
TL;DR: Artificial fibres are designed that mimic the structural features of silk and exhibit its directional water-collecting ability by tapping into both driving forces.

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).

Self-propelled dropwise condensate on superhydrophobic surfaces.
TL;DR: Continuous dropwise condensation spontaneously occurring on a superhydrophobic surface without any external forces is reported.

Fast drop movements resulting from the phase change on a gradient surface.
TL;DR: The movement of liquid drops on a surface with a radial surface tension gradient is described here and has implications for passively enhancing heat transfer in heat exchangers and heat pipes.
