Engineers look inside nanoparticles to explore how their shape improves energy storage

Many recent big technological advances in computing, communications, energy and biology have relied on very small materials, nanoparticles, with dimensions less than 1/1,000th the thickness of a sheet of paper. However, it can be hard to determine the best nanomaterials for these applications because observing nanoparticles in action requires high spatial resolution in "messy," dynamic environments.
