“…This, however, contradicts to the previous observations of (100) abundance (100), probably, due to the change in the preparation conditions. Seedless, surfactantless approach was developed resulting in Ag nanowires with a high yield, albeit with no good control over the aspect ratio (diameter 25-32 nm; length up to 12 mm) (103). Silver nitrate was reduced to silver metal at 100uC by sodium citrate in the presence of NaOH.…”

“…As such, Ag nanowires (NWs) are expected to be outstanding conductors in nanoscale electronic devices. 1,2 Of particular note is that flexible electronics based on nanomaterials has received much recent attentions. 3,4 Ag NWs hold promising potential as flexible conductors such as interconnects and electrodes.…”

This paper reports the first quantitative measurement of a full spectrum of mechanical properties of five-fold twinned silver (Ag) nanowires (NWs) including Young's modulus, yield strength and ultimate tensile strength. In situ tensile testing of Ag NWs with diameters between 34 and 130 nm was carried out inside a scanning electron microscope (SEM). Young's modulus, yield strength and ultimate tensile strength all increased as the NW diameter decreased. The maximum yield strength in our tests was found to be 2.64 GPa, which is about 50 times the bulk value and close to the theoretical value of Ag in the <110> orientation. The size effect in the yield strength is attributed to the increase in the Young's modulus. Yield strain scales reasonably well with the NW surface area, which reveals that yielding of Ag NWs is due to dislocation nucleation from surface sources. Pronounced strain hardening was observed for most NWs in our study. The strain hardening, which has not previously been reported for NWs, is mainly attributed to the presence of internal twin boundaries.

“…Despite the fact that in many studies the uniaxial growth of 1D silver nanostructure is attributed to the effect of capping agent, such as PVP and citrate,[18À20,36] other mechanisms are undoubtedly involved when no capping agent is used. [37,38] In a recent study, it was proposed that the addition of atoms in a decahedron, far from central axis, leads to an increase in strain energy, while the elongation of decahedron parallel to twin planes does not increase the strain energy. [39] In other words, the atoms Figure 6.…”

In this work, the interaction between agitation rate and oxidative etching on the growth mechanisms of silver nanowires during polyol process, the most conventional applied method for metallic nanoparticles synthesis, is evaluated. It was found that the main reason for the formation of multidiameter nanowires (MDNWs) is the local accumulation of silver ions in the system, i.e. even at a low concentration of silver ions (94 mM) under the mild agitation conditions, MDNWs were producible. Moreover, it was inferred that the more stress (stemming from the high agitation) applied on the initially formed decahedron Ag particles affects the 're-entrant grooves opening' process which results in the formation and growth of irregular nanostructures. A polynomial equation for tuning aspect ratio of silver nanowires using different concentration of CuCl 2 solution was also proposed. Finally, based on the obtained experimental data together with the thermodynamic considerations, a growth mechanism was proposed which can promisingly be employed for describing the one-dimensional growth of silver nanowires in both surfactant-modified and surfactant-free procedures.
