Graphene capsule reveals nanocrystal growth in action - physicsworld.com
"The researchers filled the graphene capsules with a solution containing platinum nanocrystals and studied the capsule using an aberration-corrected form of TEM. Park explains that his group was able to see particle nucleation and growth on the very high-resolution angstrom-scale (0.1 nm). He says that his team also observed new and unexpected stages of nanocrystal growth as they happened, in particular how certain nanocrystals frequently coalesce along the same crystallographic direction, modify their shape and form facets on their surfaces."
