Investigating the Structure of Paramagnetic Aggregates from Colloidal Emulsions (Inspace): by Alice P. Gast

By Gast, Alice P.

Excerpt
Overview: InSPACE is a microgravity fluid physics experiment that will be performed on the International Space Station (ISS). The purpose of this investigation is to obtain fundamental data of the complex properties of an exciting class of smart materials termed magnetorheological (MR) fluids. MR fluids are suspensions of small (micron-sized) super paramagnetic particles in a nonmagnetic medium. These controllable fluids can quickly transition into a nearly solid like state when exposed to a magnetic field and return to their original liquid state when the magnetic field is removed. Their relative stiffness can be controlled by controlling the strength of the magnetic field. Due to the rapid-response interface that they provide between mechanical components and electronic controls, MR fluids can be used to improve or develop new brake systems, seat suspensions, robotics, clutches, airplane landing gear, and vibration damping systems...
