Abstract: Pitch precursors affording excellent spinnability, high-level oxidation-resistance, and good carbonization yields were prepared by bromination–dehydrobromination of various ratios of pyrolyzed fuel oil and coal tar pitch. The pitches exhibited spinnabilities that were much better than… read more here.

Abstract: Our article includes numerical analysis of one narrow slice of a complex phenomenon called the greenhouse effect. We consider the most important fossil fuels: natural gas, crude oil and coal, and calculate their impact on… read more here.
