Graphene superstrates for metamaterials

, 2010
The electromagnetic properties of a photonic metamaterial are dramatically modified by a graphene monolayer superstrate. The strong polarizability of the graphene layer combined with the Fano-type, resonant plasmonic modes supported by the metamaterial ...

Electronic transport through ordered and disordered graphene grain boundaries [PDF]

, 2013
The evolution of electronic wave packets (WPs) through grain boundaries (GBs) of various structures in graphene was investigated by the numerical solution of the time-dependent Schrödinger equation. WPs were injected from a simulated STM tip placed above

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Multifunctionality and control of the crumpling and unfolding of large-area graphene [PDF]

, 2012
Crumpled graphene films are widely used, for instance in electronics energy storage, composites and biomedicine. Although it is known that the degree of crumpling affects graphene’s properties and the performance of graphene-based devices and materials ...

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

Advanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Conductance quantization suppression in the quantum Hall regime

Nature Communications, 2018
Conductance quantization is the hallmark of non-interacting confined systems. The authors show that the quantization in graphene nanoconstrictions with low edge disorder is suppressed in the quantum Hall regime.
