While graphene is the well known benchmark for nanoscale strength, new carbon structures like carbyne and monolayer amorphous carbon are challenging its dominance. Carbyne shows higher tensile strength in one dimension, while amorphous carbon offers superior fracture toughness, making it less brittle than graphene. Understanding these differences is key for developing next generation aerospace composites, flexible electronics, and industrial coatings. The shift in research moves from seeking the highest peak strength to finding materials with the best resilience and structural reliability for real world use.
