Defect‐Healed Au/rGO Coating for the Corrosion Protection of PEMFC Bipolar Plates

Advanced Materials Technologies, EarlyView.
 A defect‐healed gold/reduced graphene oxide (Au/rGO) coating is presented for stainless steel bipolar plates in polymer electrolyte membrane fuel cells. Gold nanoparticles nucleate at graphene oxide defects, blocking corrosive ion penetration and enhancing corrosion resistance, thereby ensuring durable fuel cell operation.

Photothermomechanically Efficient, Low‐Cost, High‐Cycle‐Life, Hybrid MXene‐Polymer Actuators

Advanced Materials Technologies, EarlyView.
The addition of MXenes to elastomer‐plastic‐paper films enables the creation of easily prepared actuators that are scalable for small robotic applications. Known as MXene‐polymer Trilayer Actuators (MPTAs), they bend from UV light. Their usefulness is demonstrated through kirigami‐inspired flower‐shaped art design, parallel manipulator for waveguiding,
