What is it about?
Have you ever wondered about the tiny building blocks that make up certain types of carbon found in nature and in engineered products? Our study delves into the world of sp2 amorphous carbons, a fascinating class of carbon materials with unique properties. We used advanced tools to explore these carbons and discovered some intriguing things. It turns out that sp2 amorphous carbons are made up of tiny structures called nanographites, which serve as the fundamental units in their makeup. These carbon units are like framed graphene molecules, but with some interesting twists. Depending on whether they are natural or engineered, they vary in size and possess unique molecular frameworks with specific chemical additives attached to them. Our study sheds light on the bonds and compositions involving hydrogen and oxygen within these materials. Additionally, we found that sp2 amorphous carbons are rich in stable radicals, which gives them new and exciting properties. In simple terms, our research uncovers the hidden atomic world of these carbon materials, offering new insights that can have implications in various fields such as nanotechnology and materials science.

Why is it important?
this work is the comprehensive and multianalytical approach taken to study sp2 amorphous carbons, including natural and engineered carbon blacks. The use of modern structural and compositional analytical techniques allows for a deeper understanding of the atom-molecular representation of these solids. This approach reveals commonalities among sp2 amorphous carbons, such as their composition of nanographite units and the framing of graphene molecules with chemical additives. Additionally, the study shows that sp2 amorphous carbons are strongly radicalized, making them the largest repository of stable radicals. This work is timely as it contributes to the growing field of nanotechnology and provides valuable insights into the properties and composition of sp2 amorphous carbons. The use of advanced analytical techniques and the discovery of commonalities among different types of amorphous carbons make this research significant in advancing the understanding of these materials.

Amorphous carbons in view of multianalytical consideration: normal, expected, and new
The approach based on selected set of samples and selected set of analytical tools occurred quite efficient when applying to amorphous carbons thus leading to a transformation of the current representation of the issue based on particulars into that one based on a limited set of fixed commonalities. The approach first part implies a set of different origin solid samples. The second part concerns different analytical tools. The combining part means the application of each tool to the whole set of samples. In the current study two natural amorphous carbons shungite carbon and antraxolite, as well as two engineered products carbon blacks CB632 and CB624, all of the four belonging to the elitist highest-carbon-content species, were subjected to analytical study by using modern structural and compositional analytical techniques. The approach has allowed disclosing steady points that are common to the whole class of this carbon allotrope and that may lay the foundation of a consolidate representation of what are amorphous carbons.
