Synthetic Chromatophores for Color and Pattern Morphing Skins

open access: yesAdvanced Materials, EarlyView.
Cephalopods use chromatophore organs (muscle‐actuated pigment sacs) to alter their skin color and pattern. Synthetic chromatophores, which closely mimic the mechano‐optical process found in cephalopods using stimuli‐responsive microscale hydrogel actuators, are reported.

Nickel Hydroxide Catalyzed Bias‐free Photoelectrochemical NH3 Production via Nitrate Reduction

open access: yesAdvanced Materials, EarlyView.
A bias‐free photoelectrochemical nitrate reduction reaction with high efficiency and production rate is achieved using a crystalline silicon photocathode with nickel as the catalyst. Performing the PEC NO3RR under alkaline conditions can be self‐activated of the Ni surface by forming Ni(OH)2.

Carbazole‐Based Thin Microporous Polymer Films for Photocatalytic Hydrogen Evolution

open access: yesAdvanced Materials, EarlyView.
Photocatalytic hydrogen evolution with electropolymerized microporous films enable a direct and scalable process for the production of industrial relevant amounts of hydrogen gas. For developing cost‐ and material‐effective devices it is beneficial to increase the accessible outer surface area via microstructuring and stacking of polymeric films ...

Spin‐polarized Acidic Water Electrolysis with Antenna‐Reactor Plasmonic Electrocatalysts

open access: yesAdvanced Materials, EarlyView.
A chiral plasmonic antenna–reactor electrocatalyst, integrating Au nanoflowers as the antenna and iridium single atoms as the reactor, achieves spin‐polarized and light‐driven water electrolysis in acidic media. The catalyst exhibits high activity and durability, enabled by hot‐carrier transfer and the CISS effect, as supported by operando spectroscopy
