Journal ArticleDOI
Electrum, the Gold–Silver Alloy, from the Bulk Scale to the Nanoscale: Synthesis, Properties, and Segregation Rules
Grégory Guisbiers,Rubén Mendoza-Cruz,Rubén Mendoza-Cruz,Lourdes Bazán-Díaz,Lourdes Bazán-Díaz,J. Jesús Velázquez-Salazar,Rafael Mendoza-Perez,José Antonio Robledo-Torres,José Luis Rodríguez-López,Juan Martín Montejano-Carrizales,Robert L. Whetten,Miguel Jose-Yacaman +11 more
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
Grégory Guisbiers,Sergio Mejía-Rosales,Subarna Khanal,Francisco Ruiz-Zepeda,Robert L. Whetten,Miguel José-Yacamán +5 more
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
Michel Kazan,Grégory Guisbiers,Sérgio Pereira,Maria R. Correia,Pierre Masri,Aurélien Bruyant,Sebastian Volz,Pascal Royer +7 more
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.
