Journal ArticleDOI
Epitaxial overgrowth of platinum on palladium nanocrystals
TL;DR: This work shows that both the binding affinity of a reducing agent to the Pt surface and the reduction kinetics for a Pt precursor play important roles in determining the mode of Pt overgrowth on Pd nanocrystal surface.

Electrospinning of fine hollow fibers
Younan Xia,Dan Li +1 more
TL;DR: In this article, a method for electrospinning nanofibers having a core-sheath, tubular, or composite structure is described, where a high voltage is applied between the spinneret and a spaced conductive collector.
Journal ArticleDOI
Correlated Rayleigh Scattering Spectroscopy and Scanning Electron Microscopy Studies of Au−Ag Bimetallic Nanoboxes and Nanocages
TL;DR: The optical properties of hollow nanoparticles (Au-Ag nanoboxes and nanocages) were investigated by recording Rayleigh scattering spectra of single particles, whose morphology and composition had been analyzed by scanning electron microscopy (SEM).
Journal ArticleDOI
Toward a Quantitative Understanding of the Reduction Pathways of a Salt Precursor in the Synthesis of Metal Nanocrystals
Tung-Han Yang,Hsin-Chieh Peng,Shan Zhou,Chi-Ta Lee,Shixiong Bao,Yi-Hsien Lee,Jenn-Ming Wu,Younan Xia +7 more
TL;DR: It is demonstrated that the pathway has a correlation with the reduction kinetics involved and that the reduction pathway of PdBr42- by ascorbic acid could be switched from surface to solution by raising the reaction temperature.
Journal ArticleDOI
Replacement of Poly(vinyl pyrrolidone) by Thiols: A Systematic Study of Ag Nanocube Functionalization by Surface-Enhanced Raman Scattering.
TL;DR: It is shown, for the first time, that the PVP adsorbed on the surface of Ag nanocubes was completely replaced by the thiol molecules at room temperature over the course of a few hours.
