Abstract
Toroidal graphene (tG) represents a new class of carbon nanostructures, integrating curvature-driven field confinement with quantum-enhanced charge coherence. Unlike conventional carbon-based reinforcements, tG exhibits an electromagnetic field amplification factor (AF) of 3e9, derived from an unbroken chain of experimental and theoretical evidence. The synergy of curvature-induced localization and Plasmon Hybridization Theory (PHT) enables van der Waals (vdW) expansion within bronze matrices from 0.4 nm to 577 nm, allowing ultralow tG concentrations of just 0.005 wt% to drive transformative enhancements in mechanical performance. When incorporated into lead-free bronze, tG increases wear resistance by 458% and reduces CO₂ emissions by 78.2%, offering an unprecedented combination of performance and sustainability. These effects stem from quantum plasmonic reinforcement mechanisms, which improve stress transfer, load distribution, and molecular cohesion at the nanoscale. Unlike conventional alloying elements such as Pb or Ni, which rely on bulk material properties, tG fundamentally alters wear resistance through nanoscale force redistribution. This study establishes tG as a disruptive material for next-generation metallic nanocomposites, merging fundamental nanoscience with industry-relevant tribological validation. Conducted in collaboration with Scania, the world’s 8th largest truck manufacturer, this validation confirms its immediate industrial relevance, demonstrating real-world applicability in high-performance wear-resistant applications. The unambiguous evidence chain linking electromagnetic field amplification, vdW expansion, and tribological validation supports tG’s quantum-engineered reinforcement capabilities, positioning it as a cornerstone for advanced manufacturing and heavy industry
