Oil-Water Separation: Oil-Water Separation: A Gift from the Desert (Adv. Mater. Interfaces 7/2016)

Pre-wetted sand shows approximate underwater superoleophobicity and ultralow oil-adhesion in water medium based on its strong water absorbing ability. In article number 1500650, a pre-wetted sand layer was successfully applied in the field of oil-water separation by J. Yong and co-workers and showed extremely high separation efficiency and separation capacity. This method for separating oil and water is simple, almost free of cost, green, and very efficient.
