Young Modulus Measurement of Nanostructured Palladium Thin Films
Young moduli (E2) of nanostructured metallic thin films are determined by measuring the resonance frequencies of AFM cantilevers. The cantilevers have been uniformly coated with metallic films. The E2 is determined using the vibrating beam [...]
Effect of impurities in the breaking of Gold nanowires
da Silva A.J.R., da Silva E.Z., Novaes F.D., da Silva A.J.R., da Silva E.Z., Fazzio A., Universidade de Sao Paulo, BR
Surprisingly large interatomic distances, in the range of 3.6-4.0 Å, have been reported for one atom thick gold nanowires by various experimental groups. From a theoretical viewpoint, no one has been able to reproduce the [...]
The Electronic Properties and L3 XANES of Au and Nano-Au
The electronic properties of Au crystal and nano Au have been investigated by theory and experiment. Molecularly capped nano-Au was synthesized using the two-phase method. Au nano-particles have been characterized by X-Ray Diffraction (XRD) and [...]
Melting of Ultrathin Copper Nanobridges
The previous studies on nanoclusters and infinite nanowires have shown the physical phenomena related to only the melting of nanoclusters and nanowires. This study showed the various physical phenomena of ultrathin nanobridges, such as the [...]
Polydisperse Mixture of Gold Nano-Particles
Colloids synthesized in water media, usually from direct reduction of a salt, always exhibit a size distribution, which may be characterized by TEM or SEM measurements. These are in essence polydisperse systems with a dispersion [...]
Atomistic Modeling on Structures of Ultrathin Copper Nanotubes
We have performed atomistic simulations for helical multi-shell (HMS) Cu nanowires and nanotubes. Our investigation on HMS Cu nanowires and nanotubes has revealed some physical properties that were not dealt in previous works that considered [...]
Preparation and Microstructural Characterization of Pt-Pd Bimetallic Catalysts Supported on TiO2
Nanoparticles, specially metallic nanoparticles finely dispersed onto high surface area supports, play an important role in heterogeneous catalysis because the performance of a supported metal catalyst can be related to design, which is most crucial [...]
Molecular Dynamics Simulation of Timescale Effect and Lattice Transformation of Copper Nanorod Under Bending
Mechanical behaviors of materials and structures at nanoscale are essentially different from those at macroscale, resulting from surface effect, size effect and time scale effect. In some experimental research at nanoscale, the bending displacement of [...]
Microstructure Changes Induced by Low-energy High-temperature Nitrogen Ion Implantation on Vanadium-Titanium Alloys
A detailed structural characterization of unimplanted and low-energy, nitrogen implanted V5at.%Ti alloy is presented. The alloys were produced by repeated arc melting in a high-purity He atmosphere. Samples were nitrogen-implanted at 1,2 kV and 1 [...]
