“…4). However, a statistical and systematic analysis of the errors indicates difficulties for mechanical tests at such a length scale for this type of wires similar to the large scatter of measured Young's modulus reported by other groups [57,58]. One of the main factors responsible for the high error of tensile and bending tests could be the Pt glue used for fixation of the wires [59].…”

“…Areas of experimentally observed ND traces (Traces), calculated area from friction measurements (Manip), and contact areas calculated by frozen droplet (FDM) and DMT-M (DMT) models. The used parameters are as follows: Θ = 123.8° (contact angle of Ag/SiO 2 ) [27], ν 1 = 0.17 (Poisson’s ratio of SiO 2 ) [28], ν 2 = 0.36 (Poisson’s ratio of Ag) [28], E 1 = 71.7 (Young’s modulus of SiO 2 , GPa) [28], E 1 = E Ag = 82.5 (Young’s modulus of Ag, GPa) [28], γ = 50 × 10 -3 (the work of adhesion, J/m 2 ) [21], z 0 = 0.3 (equilibrium spacing for the Lennard-Jones potential of the surfaces, nm) [29], K = 55.4 (combined elastic modulus, GPa), η = 0.2 (Tabor’s coefficient).…”

In this paper, metal nanodumbbells (NDs) formed by laser-induced melting of Ag nanowires (NWs) on an oxidized silicon substrate and their tribological properties are investigated. The mechanism of ND formation is proposed and illustrated with finite element method simulations. Tribological measurements consist in controllable real-time manipulation of NDs inside a scanning electron microscope (SEM) with simultaneous force registration. The geometry of NDs enables to distinguish between different types of motion, i.e. rolling, sliding and rotation. Real contact areas are calculated from the traces left after the displacement of NDs and compared to the contact areas predicted by the contact mechanics and frozen droplet models.PACS81.07.-b; 62.25.-g; 62.23.Hj

“…The electrodes can be readily prepared by simple and scalable methods such as spin coating, rod coating, and spraying from a AgNW-s dispersion [23,24]. AgNWs are also promising components in fabrication of flexible transparent electrodes due to high fatigue resistance of NWs [21,25]. However, such electrodes can fail due to corrosion of AgNWs exposed to ambient conditions, which adversely affects the conductivity of AgNW network [22].…”
