Edison's 1879 Light Bulb May Have Unintentionally Produced Graphene

Researchers at Rice University in Houston, United States, have suggested that Thomas Edison's original light bulb experiments in 1879 may have unintentionally produced graphene. This material, which was formally identified over a century later, could have formed during Edison's experiments. The researchers replicated aspects of the original experiment to arrive at this conclusion. The discovery links historical scientific work with modern materials science, highlighting an unexpected outcome of Edison's early electrical experiments.
