Raman spectroscopy has developed into a leading tool for characterizing organic materials
based on their rotational and vibrational spectral signatures. This article summarises …

sp 2 hybridized carbons constitute a broad class of solid phases composed primarily of
elemental carbon and can be either synthetic or naturally occurring. Some examples are …

We study the transformation from molecular to crystalline of (non-) graphitic carbons
synthesized from organic precursors by heat-treatment. Easy assessment of structural …

Vitrinite reflectance is considered one of the most reliable indicators of thermal maturity in
sedimentary basins and is widely used to calibrate numerical models that assess …

In this research, an innovative procedure is proposed to elaborate Raman spectra obtained
from nanostructured and disordered solids. As a challenging case study, biochar, a bio …

The effect of the confinement of π electrons in one–and two–dimensional domains is
illustrated with several examples ranging from linear polyene chains to planar molecules …

The standard DG-2D pattern of Raman spectra of sp 2 amorphous carbons is considered
from the viewpoint of graphene domains presenting their basic structure units (BSUs) in …

Carbon‐based black pigments are a wide group of dark‐colored materials, which are
classified according to the starting material used and their method of manufacture. Raman …

Raman spectroscopy of dispersed vitrinites needs polished surfaces to safely identify
organic particles in whole rock samples. Carbonaceous matter (CM) is very sensitive to the …

Particulate emissions from jet aircraft are a significant source of carbonaceous particles in
the troposphere and lower stratosphere. Determining their physical structure and chemistry …
