Surface Diffusion in SnTe‐PbTe Monolayer Lateral Heterostructures

Advanced Functional Materials, EarlyView.
The lateral heterostructures between 2D materials often suffer from the interdiffusion at the interfaces. Here, a surface diffusion mechanism is found to be dominating at the interfaces between semiconducting SnTe and PbTe monolayers. Atomically sharp interfaces can be achieved by suppressing this diffusion process. ABSTRACT The construction of complex

How to Chemically Protect PFAS‐Free Membranes in Fuel Cells: Radical Quenching Poly(vinylphosphonic acid) Layer

Advanced Functional Materials, EarlyView.
Hydrocarbon membranes are a greener alternative to PFSA in PEM fuel cells, but degrade rapidly from radical attack. We present a novel strategy using poly(vinylphosphonic acid) (PVPA) as a local radical scavenger. Incorporated as an interfacial barrier, PVPA enhances chemical stability and significantly extends membrane lifetime under accelerated ...

Mapping Nanoscale Buckling in Atomically Thin Cr2Ge2Te6

Advanced Functional Materials, EarlyView.
Atomic‐resolution STEM is used to resolve nanoscale buckling in monolayer Cr2Ge2Te₆. A noise‐robust image analysis reconstructs three‐dimensional lattice distortions from single plan‐view images, revealing pronounced defect‐driven nm‐scale out‐of‐plane buckling.
