Reactivity‐Guided Janus Graphene With Asymmetric Interfacial Electrostatics for Tunable Charge Transport

Advanced Materials, EarlyView.
Stepwise dual‐side functionalization creates covalent Janus graphene with chemically and electrostatically asymmetric interfaces. The resulting nonadditive surface‐potential response and pronounced charge‐transport modulation demonstrate a versatile route for tailoring the electronic properties of graphene.

Imaging chemical concentration pattern and early stages of spinodal decomposition in the AgxNa1−xBr system by scanning force microscopy

Materials Research Express, 2015
In quasi binary systems like AgBr–NaBr the demixing from the homogeneous high temperature phase into separated phases is a complex process that depends on the ageing temperature as well as on the quench rate.

Dual Single Atoms Boosting Photocatalytic Upcycling of Raw Polyvinylidene Fluoride Plastic

Advanced Materials, EarlyView.
To resolve the catastrophic disaster of plastic contamination, the Cu‐Fe dual‐single‐atom‐loaded In2P3S9 NSs photocatalyst was prepared for direct conversion of raw polyvinylidene fluoride plastic into valuable chemicals. The dual‐single‐atom catalyst exhibits exceptional performance, with a total acetic/formic acid production of ∼1351.8 µmol g−1 ...

Exceptional Elasto‐Dielectric Properties in a Highly Flexible Dielectric Elastomer Composite: The Key Roles of Parallel Elastic Nanofibers

Advanced Materials Technologies, EarlyView.
Soft dielectric elastomer composites often face a trade‐off between enhanced dielectric properties and mechanical compliance. Here, a parallel‐aligned polyurethane nanofiber network embedded in PDMS creates a flexible, durable composite with increased permittivity, low modulus, and fatigue stability after 100,000 cycles.

A Duality Between Surface Charge and Work Function in Scanning Kelvin Probe Microscopy

Advanced Materials Interfaces
Scanning Kelvin probe microscopy (SKPM) is a powerful technique for macroscopic imaging of the electrostatic potential above a surface. Though most often used to image work‐function variations of conductive surfaces, it can also be used to probe the ...
