Boron nitride coating is key ingredient in hypersaline desalination technology

Rice University’s desalination technology for hypersaline brine features a central passage for heated brine that is sandwiched between two membranes. A stainless steel heating element produces fresh, salt-free water by driving water vapor through each membrane. A coating of the 2D nanomaterial hexagonal boron nitride (hBN) protects the heating element from the highly corrosive brine. […]
