New Technique Lets Scientists Peer Within Nanoparticles, See Atomic Structure in 3-D

UCLA researchers are now able to peer deep within the world’s tiniest structures to create three-dimensional images of individual atoms and their positions. Their research, published March 22 in the journal Nature, presents a new method for directly measuring the atomic structure of nanomaterials.

“This is the first experiment where we can directly see local structures in three dimensions at atomic-scale resolution — that’s never been done before,” said Jianwei (John) Miao, a professor of physics and astronomy and a researcher with the California NanoSystems Institute (CNSI) at UCLA.
