How does degree of intercalation depend on graphite particle size in liquid intercalation (H2SO4-HNO3)? Can oxidation occur in very fine particles?

I wish to intercalate very fine graphite particles through a mixture of concentrated H2SO4 and HNO3. Normally, small particle size results in greater degree of intercalation. Is it possible for...
