Decoding Proton‐Coupled Electron Transfer Mechanism of Nicotine for Multi‐Scenario Portable Electrochemical Sensing

open access: yesAdvanced Science, EarlyView.
A key challenge in nicotine electroanalysis is the unresolved complexity of its interface process, which directly determines sensor metrics. Herein, the proton‐coupled electron transfer mechanism of nicotine is decoded for multi‐scenario portable electrochemical sensing.

Structural and Mechanical Dynamics of Polymer Membranes Across Multilength Scales

open access: yesAdvanced Science, EarlyView.
Distinct surface‐to‐bulk mechanical contrasts in polymer membranes were unveiled, highlighting the need to probe both regions to fully capture their functional behavior. By integrating in situ SAXS–WAXS with AFM‐based nanomechanics, nanodomain‐level heterogeneity and real‐time structural transformations induced by thermal and mechanical stimuli were ...

Lattice Carbon‐Mediated Ultralow‐Barrier C–C Coupling for Selective CO Electroreduction to Ethylene

open access: yesAdvanced Science, EarlyView.
Combined DFT and molecular dynamics simulations reveal that while the lattice carbon at the MXene edge cannot directly bind CO2 to form ethylene, it acts as an active center to promote C─C coupling between adjacent *CO intermediates for ethylene production.

Dorsal Raphe VIP Neurons Are Critical for Survival‐Oriented Vigilance

open access: yesAdvanced Science, EarlyView.
DRNVIP neurons in mice and primates are strategically positioned to influence the central extended amygdala via feedback loops. They regulate the excitability of PKC‐δ neurons in the ovBNST and CeA through glutamate release. Their ablation heightens activity in these regions, disrupts active‐phase sleep architecture, enhances risk assessment behaviors ...

Computational Microscopy of Spatial Dopant Distribution in Conjugated Polymer

open access: yesAdvanced Electronic Materials, EarlyView.
The study employed molecular dynamics simulations to investigate the distribution of dopants in conjugated polymers. The simulations revealed that dopants are randomly distributed without forming clusters, contrasting with experimental findings of dopant clustering.
