Abstract:
The development of nano-magnetorheological (nMR) fluids for microfluidic applications has progressed in two stages: (1) the synthesis of Fe-based powders, and (2) the incorporation of such powders into a carrier fluid viz. ethylene glycol (0.1-1.0 vol%) and grease (20-80 wt%) for enhanced heat transfer and microvalve applications, respectively. In this study, the co-precipitation and sonochemical processes were optimized to achieve a scalable technique for producing nMR fluids. X-ray and SEM/TEM results showed the particles are comprised of the iron bcc phase with primary particle sizes
