Shear thickening fluid (STF) is a dense colloidal suspension of nanoparticles in a carrier fluid in which the viscosity increases dramatically with a rise in shear rate. Due to the excellent energy absorption and energy dissipation of STF, there is a desire to employ STFs in a variety of impact applications. In this study, a comprehensive review on STFs' …

More copper atoms leave the ε into the η here, and also more copper atoms have diffused from the copper substrate at the base of the undulations. The ε grows by reaction of copper with η at the ε/η interface. Copper diffusion drives the growth process. Because the temperature is low, diffusion of copper along grain boundaries or dislocations

The process isolates the impurities that concentrate in the molten zones, leaving the portions behind them somewhat more pure. This process is repeated until impurities are moved to the end of the rod and cut off, resulting in an almost completely pure metal rod.
