Abstract:Goldbeating is the ancient craft of thinning bulk gold into gossamer leaves. Pioneered by ancient Egyptian craftsmen, modern mechanized iterations of this technique can fabricate sheets as thin as ∼100 nm. We take inspiration from this millennia-old craft and adapt it to the nanoscale regime, using colloidally-synthesized 0D/1D gold nanoparticles (AuNPs) as highly ductile and malleable nanoscopic gold ingots and subjecting them to solid-state, uniaxial compression. The applied stress induces anisotropic morpho… Show more
