Fig. 5: Scaling mitigation of hBN nanocoating in real oil & gas produced water.
From: Ultrahigh resistance of hexagonal boron nitride to mineral scale formation

A Photograph of stainless steel (SS) tube before (top) and after (bottom) the growth of hBN nanocoating (hBN@SS); B A photograph of produced water taken from an oil & gas production site in Texas, USA; Scaling behavior of the C pristine and D hBN coated SS tube during 14 days of exposure to real produced water. The scale bars are 1 mm in length. Red dash circles indicate the original inner diameter of the pristine SS tube.
