The aim of this review article is to report the most recent developments in the understanding
of and beliefs about the properties of polymer hybrid composites that are reinforced with …

In order to identify the parameters that best characterize the chemical and structural
evolution of organic matter during coalification, the relationships between optical, chemical …

This short communication reports the synthesis of carbon quantum dots (CQDs) from US
anthracite and bituminous coals by oxidation in presence of ultrasonic stimulation. The …

The present work is focused on the characterization of natural samples as end-member
products of coalification process—semi-graphites and graphites, and on the characterization …

In this work, two Pennsylvania anthracites were calcined (1420° C) and then graphitized
(3000° C). The objective of this study was to evaluate the influence of anthracite rank on the …

Middle Permian coal from the Yongan Coalfield, Fujian Province, China, with a maximum
vitrinite reflectance (VR max) of 5.33%–8.95%, indicating a typical meta-anthracite stage …

The present work is focused on the microstructural evolution of major components of
carbonaceous samples during high temperature treatment, ie vitrinite in raw anthracites and …

The aim of this study is the optical and structural (micro-Raman spectroscopy and X-ray
diffraction) characterization of particles formed during the high temperature treatment (HTT) …

Coke samples made from coals and blends of the Upper Silesian Coal Basin, Poland were
studied to determine relationships between their reflectance parameters (Rmax, Rmin, Rbi) …

Graphite can be artificially converted from anthracites under high temperatures; however,
the exact mechanism through which inorganic minerals contribute to the graphitization …
