title: A process-analysis microsystem based on density gradient centrifugation and its application in the study of the galvanic replacement mechanism of Ag nanoplates with HAuCl4.
abstract: Density gradient ultracentrifuge separation has been employed as a process-analysis microsystem combining a microreactor and a separator. As a paradigm, intermediates formed after tens of seconds in the galvanic replacement of Ag nanoplates in high concentrated AuCl(4)(-) solution are captured, providing evidence of the mechanism of the reaction, which is difficult to obtain in other ways.
