Scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a new way to determine atomic structures from nanocrystals previously considered unusable, ...

After decades of debate, researchers say that they have found the clearest evidence yet for this rare form of carbon.

Virtual apertures let researchers isolate and solve atomic structures from individual nanocrystals embedded in dense clusters, providing valuable new data for energy and pharmaceutical applications.
