What is it about?

The global water crisis is a pressing issue that humanity is already grappling with, and its severity is expected to worsen. The atmosphere holds significant potential as a source of pure water, as evidenced by certain desert-dwelling animals that have developed water-capturing abilities. Inspired by these animals, we propose employing nanotechnology to create a device capable of capturing and transporting pure water from vapor. We have conducted an analysis of the device's performance, which has yielded promising results.

Why is it important?

We propose using carbon nanocones (CNCs) to capture water vapor. The conic geometry of CNCs acts as a funnel, enhancing molecule capture. By combining wettabilities with this nanomaterial, we have discovered that the device can effectively condense and capture droplets from vapor. It exhibits a linear regime of capture, which is beneficial for water harvesting. Additionally, we have studied the performance of multiple nanones and determined that the distance between the CNCs significantly affects the capture mechanism.


We hope that this article will contribute to finding solutions for the water scarcity issue, while also enhancing our understanding of water behavior within nanomaterials.
