Spectroscopical study of natural nanostructured carbonaceous material shungite

Spectroscopical study of natural nanostructured carbonaceous material shungite

The correlation between morphology, local structure and magnetic properties of the different origin shungite material with nanocarbon content 25-40 wt. % was studied by SEM, EPR, and Raman scattering methods. It was established that structure of the shungite samples is formed by micron size agglomer...
