Cost Effective Photothermal Materials Selection for Direct Solar-Driven Evaporation.

The cornerstone of eco-friendly and affordable freshwater generation lies in harnessing solar energy for water evaporation. This process involves extracting vapor from liquid water using solar energy. Numerous innovative, low-cost materials have been proposed for this purpose.

Modifications of the wetting characteristics of electrodeposited porous copper by controlling the plating parameters and storage conditions.

The wetting behavior of copper is important for many engineering applications. The present study demonstrates a method to modify the wetting characteristics of copper surfaces by developing porous structures via the promotion of hydrogen bubbles and rapid and nonuniform growth of the deposits. The porous copper deposits are fabricated with various controlled plating parameters, and subsequently stored in different conditions, including air, water, and saline solution, to assess the possible influence of the storage conditions on the wetting behavior.
