TLDR
This work shows that graphene's electronic structure is captured in its Raman spectrum that clearly evolves with the number of layers, and allows unambiguous, high-throughput, nondestructive identification of graphene layers, which is critically lacking in this emerging research area.Abstract:
Graphene is the two-dimensional building block for carbon allotropes of every other dimensionality We show that its electronic structure is captured in its Raman spectrum that clearly evolves with the number of layers The D peak second order changes in shape, width, and position for an increasing number of layers, reflecting the change in the electron bands via a double resonant Raman process The G peak slightly down-shifts This allows unambiguous, high-throughput, nondestructive identification of graphene layers, which is critically lacking in this emerging research arearead more

Synthesis of High Quality Monolayer Graphene at Reduced Temperature on Hydrogen-Enriched Evaporated Copper (111) Films
TL;DR: This study suggests that reduced temperature, hydrogen-free synthesis of defect-negligible monolayer graphene is feasible, with the potential to shape and scale graphene grains by controlling the size and crystal orientation of the underlying copper grains.

Enhanced room temperature sensing of Co3O4-intercalated reduced graphene oxide based gas sensors
TL;DR: In this paper, the room temperature gas sensing properties of the Co3O4 intercalated reduced graphene oxide (rGO) based thin film semiconductor sensors were investigated and two possible reasons have been discussed including the increased surface area of the rGO thick film by the intercalation of Co 3O4 nanocrystals and the Co 3+-carbon coupling effect for the rapid response.

Smart Hybridization of TiO2 Nanorods and Fe3O4 Nanoparticles with Pristine Graphene Nanosheets: Hierarchically Nanoengineered Ternary Heterostructures for High-Rate Lithium Storage
TL;DR: In this paper, a smart hybridization strategy is proposed for the hierarchical co-assembly of TiO 2 nanorods and Fe 3 O 4 nanoparticles on pristine graphene nanosheets, aiming to simultaneously address the capacity and conductivity defi ciencies by coupling it with high capacity (Fe 3 O4 ) and high conductivity (pristine graphene) components.
