On‐Surface Synthesis of Bismuth Monolayers through Ice‐Confined Redox Reactions

Advanced Materials, EarlyView.
We report an ice‐confined growth strategy for the synthesis of atomically thin 2D bismuth and related 2D metals. This approach involves rapid freezing of a BiCl3 aqueous solution on an aluminum foil using liquid nitrogen, which triggers interfacial redox reactions between the ice and the aluminum surface.

Atomically Resolved Acoustic Dynamics Coupled with Magnetic Order in a Van der Waals Antiferromagnet

Advanced Materials, EarlyView.
Magnetically coupled acoustic phonon modes (f1, f2, f3) are captured by ultrafast X‐ray diffraction in a prototypical van der Waals antiferromagnet FePS3, including their atomic displacement vectors (u) and the acoustic propagation wave vectors (k). Notably, the atomic displacement vector and amplitude of these modes, represented by the direction and ...

Field‐Effect Transistors from Artificial Charged Domain Walls in Stacked Van der Waals Ferroelectric α‐In2Se3

Advanced Materials, EarlyView.
This study utilizes the van der Waals stacking of ferroelectric α$\alpha$‐In2Se3 to fabricate in‐plane artificial charged domain walls. These charged domain walls are electrically accessible, gate‐tunable, and show 2–9 orders of magnitude higher conductance than charged domain walls from thin film ferroelectrics, allowing their integration in field ...

Engineering Active Metal Oxide Interfaces on MOF‐Derived 3D Carbon Architecture for Small‐Molecule Biosensing

Advanced Materials Interfaces, EarlyView.
MOFs awaken graphene. MOF‐assisted ultrafast laser writing patterns porous laser‐induced graphene with CuO‐active nanodomains, creating an aptamer‐ready interface for small‐molecule capture. Coupled to an extended‐gate FET, the hybrid converts subtle biochemical binding into a clear electrical signal for resilient cortisol sensing in aqueous media ...
