Breakthrough in Desalination of Water

This report in phys.org describes a big breakthrough in a more efficient and sustainable way to filter salt and metal ions from water.  This method could significantly lower costs of environmental cleanup for the mining industry.  This might also be an alternative process for collection lithium for the demands of battery production.
