Electrochemical properties of organic mixed ionic–electronic conductors depend on their microstructure in operational ionic environments. The microstructure of a model organic mixed ionic–electronic conductor across multiple length scales in both dry and hydrated states, as well as its evolution on hydration, is revealed using cryogenic four-dimensional scanning transmission electron microscopy.

A framework is presented to automate the design of flexible metamaterial structures that can execute desired nonlinear dynamic tasks and have reprogrammable functionality.

Electrons in solids carry orbital angular momentum in diverse non-equilibrium situations. This orbital current is often overlooked when considering electronic transport.
