This solar-powered desalination device turns seawater into drinking water, can also extract lithium

The work, led by Chunlei Guo, a professor of optics and physics, centers on a specially treated surface known as superwicking black metal. The material is created by texturing a metal surface with femtosecond laser pulses, altering its structure at microscopic scales. This process gives the surface two key properties:...
