Anomalous Kondo resonance mediated by semiconducting graphene nanoribbons in a molecular heterostructure

Nature Communications, 2017
Semiconducting graphene nanoribbon provides a platform for band-gap engineering desired for electronic and optoelectronic applications. Here, Li et al. show that graphene nanoribbon can effectively mediate the interaction of molecular magnetic moment and

Cross‐Scale Engineering of Single‐Atom Catalysts from Local Planar Coordination to Spatial Architectures

Small, EarlyView.
This Review presents a cross‐scale framework for single‐atom catalysts, spanning in‐plane and out‐of‐plane coordination; primary coordination, secondary‐sphere interactions, through‐space microenvironments and support interfaces; individual sites and macroscopic architectures; and static design and directed dynamic reconstruction.

Four-terminal impedance of a graphene nanoribbon based structure

, 2014
The four-terminal impedance is studied in a typical graphene nanoribbon based structure. When two additional voltage probes are attached, the results show that at the Dirac point, both the real and imaginary parts of the impedance are negative.

Tailoring MXene Flake Morphology via Aerosol Jet Printing for Biological and Strain Sensor Applications

Small, EarlyView.
Aerosol Jet Printing (AJP), coupled with a novel in situ monitoring method, enabled the controlled fabrication of aligned and crumpled Ti3C2Tx MXenes for diverse applications. Demonstrated across multiple 2D materials, this scalable strategy stablishes flake morphology as a controllable design parameter for engineering application‐specific material ...

Plasma Treatment on 1D Tungsten Disulfide Carbon Core–Shell Composites for Improved Performance in the Hydrogen Evolution Reaction

Small, EarlyView.
RF Ar plasma exposure selectively activates carbon‐coated WS2 nanotubes, substantially lowering the HER overpotential while preserving an ordered, conductive framework. A subsequent D2 plasma step produces interlayer expansion and greater structural disorder, reducing activity.

Stimuli‐responsive nanostructured hydrogen sulfide donors for enhanced cancer treatments

Smart Molecules, EarlyView.
Three typical kinds of stimuli‐responsive nanostructured hydrogen sulfide (H2S) donors are reviewed. The nanostructures ensure precise delivery of H2S to the lesion site and regulate the release behavior. The H2S‐based gas therapy has been used to synergize with other cancer treatment modalities, achieving enhanced efficacy while reducing side effects.
