Accompanying Structural Transformations in Polarity Switching of Heavily Doped Conjugated Polymers

open access: yesAdvanced Materials, EarlyView.
The polarity switching of heavily doped p‐type conjugated polymers (CPs) toward environmentally stable electron‐rich thin films is demonstrated. Multiscale analyses, incorporating spectroscopic, electrochemical, and scattering techniques, reveal structural and chemical transformations induced by excessive doping with AuCl3.

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.

Anchoring Unimolecular Metal Chloride as a Sterically Active Site for Conformal Zinc Electrodeposition

open access: yesAdvanced Materials, EarlyView.
An octahedrally coordinated MnCl2N4 structure anchored on hard carbon tailors the electronic environment of single atoms to lower zinc nucleation barriers. Chloride‐assisted Zn adsorption with Jahn‐Teller distortion and residual Zn enables reduced overpotential.

Magnetically “Programming” Cobalt‐Doped Iron Oxide Nanoparticles for Localized Induction Heating: Triggering a Collective Effect of Magnetic Moment Alignment on Demand

open access: yesAdvanced Materials, EarlyView.
This study demonstrates enhanced induction heating in cobalt‐doped iron oxide nanoparticles via specific pre‐magnetization, induced by the pre‐alignment of magnetic moments. By correlating Co content with magnetic properties, the research highlights how magnetic pre‐programming enables localized, on‐demand debonding in composites.
