Efficient Water Collection from Biodesigned and Natural Inclined Surfaces: Influence of Inclination Angle on Atmospheric Water Collection

Abstract

Water is one of the most important and crucial indicators of sustainable development goals (SDGs) for humans and other living organisms. Water demand has outstripped supply, resulting in shortage on a worldwide scale, particularly in arid regions. This water scarcity has impeded agricultural productivity and other developmental projects with the ongoing global warming and other anthropogenic activities making it more complicated. To address the worldwide water crisis, it is worthwhile to convert atmospheric air to drinking water. Sequel to that, a hydrophobic surface was designed using facile lithography to compare its water harvesting efficiency with a hydrophilic surface at different orientation angles. For the research, the hydrophobic designed surface is called biodesigned material, while the hydrophilic natural surface is a Mangifera indica leaf (MIL). It is against this background that we seek to investigate the most suitable orientation angle good for efficient water harvesting. To that end, a 60° inclination angle is the most efficacious orientation for water collection as it outperformed the 30 and 45° orientation angles. To minimize re-evaporation, absorption, suction, and other environmental challenges that impede efficient collection, atmospheric moisture should be collected immediately from functional surfaces.

Environmentally Friendly and All-Dry Hydrophobic Patterning of Graphene Oxide for Fog Harvesting

“…The as-condensed droplets, which are able to grow in size and merge with others, are collected in containers placed below the meshes. Recently, a biomimetic approach has become a hot topic in fog harvesting studies in order to develop materials or surfaces with maximized fog-collection efficiency. − The most recent studies carried out to improve the fog collecting efficiency were based on the combination of hydrophobic and hydrophilic domains on a single surface, which was inspired by Namib desert beetle. − Namib desert beetle is a well-known example of natural fog harvesting species, which captures water because of its dorsal surface possessing specially distributed hydrophobic and hydrophilic parts.…”

Catalytic Janus Nanoparticle-Based Recyclable Emulsifiers for Collaborative Treatment of Water-Soluble and Water-Insoluble Organic Pollutants

“…A global water shortage crisis is imminent, and water is precious in sustaining the survival of humans and other living things on Earth. 1 With the development of the industry, water pollution caused by organic pollutants has emerged as a significant threat to human health. 2 Owing to the substantial detrimental effects of organic pollution, researchers have been intensively engaged in the development of efficient treatment methods and technologies for organic pollution wastewater, such as biological treatment, chemical flocculation, chemical oxidation, adsorption, and electrochemistry.…”
