Carbon nanofibers (CNFs) are exquisite conductors of heat and electricity, and have very high tensile strength. Made up of layers of individual graphene sheets, they show promise in high-performance electronics, textiles, and other industrial and consumer applications. They also exhibit quantum behaviors that make them unique for a range of metamaterials.

Harmful Greenhouse Gases Repurposed into Carbon Nanofibers

While a simple and economic method to synthesize carbon nanofibers (CNFs) has eluded scientists for decades, the most impressive feature of GWU’s “one-pot” synthesis is that it...
