Internal combustion engines are among the main sources of soot particles, especially when
non-homogeneous and high fuel-air ratio conditions are achieved in the combustion …

Coals varying in rank from lignite to anthracite were comprehensively characterized with
regard to chemical structure using FTIR and Raman spectroscopy. Structural parameters …

In recent years, the major coal producing areas in China have entered the period of deep
mining, with coal rank changing from low-rank coal (LRC) to middle-high rank coal (MHRC) …

In the present study, carbon black activated by CO2 gas was examined through XRD
analysis, especially with regard to changes in its structural parameters. Based on the results …

Low-weight components of coal macromolecule were subjected to pyrolysis and
condensation when magmatic rock intruded into coal measure, eventually, the residual …

Coal is the most abundant and readily combustible energy resource being used worldwide.
However, its structural characteristic creates a perception that coal is only useful for …

Sheet-like graphitic carbon with a porous structure can provide low-resistant pathways and
short ion-diffusion channels for energy storage, and thus is expected to be an excellent …
