Imaging polymer’s atomic-scale structure
This image shows a rendering (gray and pink) of the molecular structure of a peptoid polymer that was studied by a team led by Berkeley Lab and UC Berkeley. The successful imaging of a polymer’s atomic-scale structure could inform new designs for plastics, like those that form the water bottles shown in the background.

New manganese materials bolster cathode capacity
An array of lithium-ion batteries stacked side by side. Conventional lithium-ion batteries made from cobalt-based cathodes (orange) and a battery with a manganese-based cathode made from two new materials (blue). The cathode structures are depicted under the surface of the batteries. The new manganese-based materials have a disordered rocksalt structure that provides higher energy density than cobalt-based batteries. A manganese ion (blue sphere) yields two electrons during the battery discharge cycle, delivering twice the capacity of the cobalt ion (orange sphere), which only yields one electron.
