In an article recently published in the journal ACS Nano, the researchers reported heteroepitaxially grown polycrystalline graphene monolayer with patterned gradient grain boundary (GB) density to aid ...

Atomic transport along grain boundaries (GB) and interphase boundaries (IB) plays a key role in a large number of metallurgical processes. The experimental determination of GB or IB diffusion ...

characterization of grain boundaries (GB) is of critical importance in materials studies. Although focused ion beam (FIB) methods have previously been employed to prepare samples for atom probe ...
