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.

Hardware Implementation of On‐Chip Hebbian Learning Through Integrated Neuromorphic Architecture

open access: yesAdvanced Materials, EarlyView.
This work presents a neuromorphic hardware platform that integrates presynaptic transistors, threshold switching neurons, and adaptive feedback synapses. The architecture enables on‐chip Hebbian learning through correlation‐based weight updates without external training circuits.

Synthesis and Electrochemistry of Stacking Fault‐Free β‐NaMnO2

open access: yesAdvanced Materials, EarlyView.
An inherent tendency to form intergrown stacking faults in corrugated layered β‐NaMnO2 hinders the understanding of its structural transition during electrochemical reaction. The synthesis of fault‐free β‐NaMnO2 unveils in‐plane sliding of corrugated MnO2 as well as excellent capacity retention in Na cells, providing a strategy to exploit Mn‐based ...

Spatial Coordination Structure‐Driven Enzyme‐Like Selectivity in Single‐Atom Nanozymes

open access: yesAdvanced Materials, EarlyView.
Sun et al. reviews recent progress in enhancing the enzyme‐like catalytic selectivity of SAzymes through the rational design of their spatial coordination structures. They emphasize the structure‐activity relationships of various attributes of these coordination structures in promoting selective catalytic behavior, the strategic design of coordination ...
