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

Renewing functionalized graphene as electrodes for high-performance supercapacitors.
TL;DR: An acid-assisted ultrarapid thermal strategy is developed for constructing specifically functionalized graphene that presents an opportunity for developing further high-performance graphene-based electrodes to bridge the performance gap between traditional capacitors and batteries.

Probing Strain-Induced Electronic Structure Change in Graphene by Raman Spectroscopy
TL;DR: Study of Raman scattering of the two-dimensional mode of single-layer graphene under uniaxial stress and which implicates two types of modification of the low-energy electronic structure of graphene: a deformation of the Dirac cone and its displacement away from the K point.

TL;DR: The results reveal that graphene substrates exhibited excellent biocompatibility, as cell viability and morphology were not affected and neurites, one of the key structures for neural functions, are affected by graphene during the development until maturation in a mouse hippocampal culture model.
