Characterization of Bare and Surface-Modified Gold Nanoparticles. Department of Chemical and Environmental Engineering University of California, Riverside. Thi (Kathy) Nguyen Huynh Graduate student mentor: Hyunjung N. Kim Advisor: Dr. Sharon Walker. Outline. Background Objectives

Die Casting Basics. Die is closed. Metal is drawn in to tool (plunger). Tool injects metal into cavity. Cavity continues to fill. (fractions of a second). Metal solidifies under pressure. Die is opened. Casting removed. Machine recovers to initial orientation (cycle starts over).
