Coal is a combustible black or brownish-black hard substance within the earth that is used as a fuel. The Coal includes inherent moisture, consists of more than 50 percent by weight and more than 70 percent by volume of carbonaceous material. It is formed from plant remains that have been compacted, hardened, chemically altered, and metamorphosed by heat and pressure over geologic time.

From Black Gold to Tech Marvel: Coal's New Role in Electronics (Source: Oil Price on 4 January 2024): By Brian Westenhaus - A joint research effort from the University of Illinois Urbana-Champaign, the National Energy Technology Laboratory, Oak Ridge National Laboratory and the Taiwan Semiconductor Manufacturing Company has shown how coal can play a vital role in next-generation electronic devices. Coal is an abundant resource in the United States that has, unfortunately, contributed to air pollution through its use as a combustible fossil fuel. As the country transitions to other means of energy production, it will be important to consider and reevaluate coal’s economic role. Coal may actually play a vital role in next-generation electronic devices. Qing Cao, a U. of I. materials science & engineering professor and a co-lead of the collaboration said, “Coal is usually thought of as something bulky and dirty, but the processing techniques we’ve developed can transform it into high-purity materials just a couple of atoms thick. Their unique atomic structures and properties are ideal for making some of the smallest possible electronics with performance superior to state-of-the art.” ...
