Ni–Fe layered double hydroxide nanoplates loaded on a three-dimensional electrochemically reduced graphene oxide electrode for efficient water oxidation, exhibiting higher activity, kinetics, and stability than those of the IrO₂catalyst.

Introducing oligoaniline into a vitrimer resulted in a smart material that simultaneously responds to six different stimuli and performs six different functions.

An electrochemical capacitor (EC) with H ₂ SO ₄ treated PEDOT:PSS/graphite foil electrodes exhibited the highest areal and volumetric specific capacitances among the reported ECs with phase angles larger than −80° at 120 Hz.
