Nanotechnology: ferrofluids
Click Image for Gallery
Learn of one nanomaterial, ferrofluid,and some of its applications in modern technology. Create magnetite nanoparticles through a precipitation reaction, while employing a surfactant to create a colloidal suspension of magnetite nanoparticles (ferrofluid). Then examine the response of ferrofluid when exposed to a magnetic field. Teaching notes included.
Class size: 15 students.
