    The Micromechanisms of Deformation in Nanoporous Gold

    We have carried out a TEM investigation of the micromechanisms of deformation in these nanoporous gold specimens after compression testing. We find that the nanoporous specimens show deformation localised to t...

    Strain gradients and the strength of nanoporous gold

    The very high strengths that have been reported for nanoporous gold may be related to strain gradients within the deforming porous microstructure. We present a mechanism-based model for the strength of nanopor...

    Universal Scaled Strength Behaviour for Micropillars and Nanoporous Materials

    The strength of submicron fcc structure metal columns, σ, fabricated by FIB machining or electrodeposition, shows a strong correlation with specimen diameter, d, with σ/µ = A(d/b)−0.63, where A is a constant, µ i...

    The Strength of Gold Nanowires and Nanoporous Gold

    We have measured the yield strength of gold nanowires with diameters in the range from 30 to 70 nm fabricated by electro-deposition into porous alumina templates. All nanowire sizes showed yield strengths much...

    The Growth and Mechanical Properties of Gold Nanowires

    We have measured the yield strength of gold nanowire forests with mean diameter 30, 60 and 70 nm fabricated by electro-deposition into porous alumina templates. All nanowire sizes showed yield strengths much g...
