(PhysOrg.com) -- A technique for real-time monitoring of the galvanic replacement reaction between silver nanowires and aqueous gold salt solutions using in situ flow-cell transmission X-ray microscopy (TXM) has been developed by scientists in the Center for Nanoscale Materials Nanophotonics Group and the Advanced Photon Source (APS) X-Ray Science Division. Glimpses of the morphological evolution of solid silver nanowires into hollow gold nanotubes are available for the first time by using this technique.
