Fig. 3From: Effect of interface-active proteins on the salt crystal size in waterborne hybrid materialsSEM images of NaCl crystals formed after drying a droplet of a solution containing 375 mM NaCl and 5 mM Tris–HCl buffer. (A), (B) Show the SE-SEM images of an NaCl crystal and its halo region, respectively. (C) Displays the surface (bottom left) and halo regions (top right) of a salt crystal while (D) depicts the substrate area away from any NaCl crystalsBack to article page
