-	The potential energy barriers of the vacancy as it moves towards the surface, essentially destroying itself once it reaches there.</p>
+	The molecular dynamics simulation shows a vacancy moving from the bulk to the surface along the minimum energy path.
+	Since you cannot physically track a vacancy, as it does not exist, instead it's easiest to track atoms with fewer than 4 bonds.
+	The graph tracks the vacancy and shows its energy along the path to the surface. 
+	There is a clear lowering of energy as the vacancy gets closer to the surface, implying there should be some form of diffusion gradient which could cause the destruction of the vacancy.
