Researchers in the US have succeeded in directly visualizing the back-and-forth movement of silicon atoms that are clustered in graphene pores. Being able to analyse small clusters in this way could improve our understanding of how different atomic configurations determine a material's properties. The ability to engineer clusters with specific properties could lead to new devices for electronics and optoelectronics. Also, a better understanding of how pores behave in graphene could lead to practical applications such as water desalination.
Those silicon atoms are performing a nice ballet
