Study of a rhombohedral graphite X-ray filter using the sphere-in-contact model
2019, Chemical Physics LettersCitation Excerpt :We find that there are certain new properties of graphite observed in the sphere-in-contact model, and these are attributed to the use of proper scale and proportions. Based on these physical model it becomes obvious that diffusion through the layer is unlikely [34], except for elements with small relative atomic mass (e.g., Helium [35]), but diffusion between the layers (e.g., Lithium-cation [36]) is possible due to a gap of 2.0 Å between two consecutive layers of graphite. This gap can fit small molecules, for example it fits water with its symmetry axis lying along the basal plane as the vdW radius of oxygen is 1.52 Å), which explains the exfoliation of graphene from graphite in water [37] and the diffusion of water in graphite-oxides (GO) [38].
