This is a remarkable case where cleverly designed materials can address numerous environmental issues at the same time. The Janus structure is a highly remarkable case in which one side uniquely rejects the oil while the other one utilizes solar energy for quick evaporation and desalination processes. However, what is most interesting is the difference between magnificent laboratory tests and real-life implementations. It will be critical to test durability, fouling, uptime, and costs of the technology at big scales. If these problems could be resolved, this method could bring a lot of value to tropical and industrial certain regions where oil pollution makes regular desalination not feasible.
