observations of centrifugation of other groups (9, 12–16). This is a unique systematic study of shape separation, where central role of hydrodynamics of these particles is elucidated to explain their separation procedure. We use gold NRs synthesized by a seedmediated method (3) for illustrating the use of centrifugation for shape separation.
Here is how a gravity gold concentrator (centrifuge) works as a separator: Make sure the concentrator has been correctly assembled and that all bolts have been tightened. If required, attach a funnel to the material feed inlet. If necessary, connect a hose to the tailings outlet. Place the concentrator on a raised structure such as blocks.
The growth of gold nanoparticles by reduction by citrate and ascorbic acid has been examined in detail to explore the parameter space of reaction conditions. It is found that gold particles can be produced in a wide range of sizes, from 9 to 120 nm, with defined size distribution, following the earlier work of Turkevich and Frens. The reaction is initiated thermally or in comparison by UV ...
