Journal ArticleDOI

Electrum, the Gold–Silver Alloy, from the Bulk Scale to the Nanoscale: Synthesis, Properties, and Segregation Rules

TL;DR: The optical properties of Au–Ag nanoparticles show the control that can be achieved in the tuning of the local surface plasmon resonance, depending of the alloy content, the chemical ordering, the morphology, the size of the nanoparticle, and the nature of the surrounding environment.
Journal ArticleDOI

Gold–Copper Nano-Alloy, “Tumbaga”, in the Era of Nano: Phase Diagram and Segregation

TL;DR: It is found that the congruent melting point of these nanoparticles is shifted with respect to both size and composition (copper enrichment) and the most stable structures were determined to be the dodecahedron, truncated octahedrons, and icosahedron with a Cu-rich core/Au-rich surface.
Journal ArticleDOI

Size-Dependent Materials Properties Toward a Universal Equation

TL;DR: A universal equation is developed here which is particularly helpful when experiments are difficult to lead on a specific material property and only requires the knowledge of the surface area to volume ratio of the nanomaterial, its size as well as the statistic followed by the particles involved in the considered material property.
Journal ArticleDOI

Mechanical and Thermal Properties of Metallic and Semiconductive Nanostructures

TL;DR: In this article, the melting temperature at the nanoscale, Tm, for different shapes of free-standing nanostructures is investigated using a top-down approach, and a phase transition stress model is proposed to evaluate the intrinsic strain and stress during the first steps of solidification.
Journal ArticleDOI

Thermal conductivity of silicon bulk and nanowires: Effects of isotopic composition, phonon confinement, and surface roughness

TL;DR: In this article, a rigorous analysis of the thermal conductivity of bulk silicon (Si) and Si nanowires (Si NWs) is presented, which takes into account the exact physical nature of the various acoustic and optical phonon mechanisms.
