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

open access: yesAdvanced 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.

Site‐Selective Polyvinylpyrrolidone Adsorption Behavior for 3D Heterogeneous Integration

open access: yesAdvanced Materials Technologies, EarlyView.
Site‐selective adsorption behavior is presented with polyvinylpyrrolidone on a Cu/SiO2 pattern wafer, which enables 3D heterogeneous integration. Owing to the site‐selective adsorption behavior and its corresponding electrostatic interaction between SiO2 nanoparticles and the Cu surface, the selectivity of Cu/SiO2 is arbitrarily controlled ...

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

open access: yesAdvanced 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,
