  2. Ferrofluid - Wikipedia

    en.wikipedia.org/wiki/Ferrofluid

    Ferrofluid is a liquid that is attracted to the poles of a magnet.It is a colloidal liquid made of nanoscale ferromagnetic or ferrimagnetic particles suspended in a carrier fluid (usually an organic solvent or water). [1]

  3. Ferrofluid mirror - Wikipedia

    en.wikipedia.org/wiki/Ferrofluid_mirror

    A ferrofluid mirror is a type of deformable mirror with a reflective liquid surface, commonly used in adaptive optics. It is made of ferrofluid and magnetic iron particles in ethylene glycol, the basis of automotive antifreeze. [1] The ferrofluid mirror changes shape instantly when a magnetic field is applied.

    en.wikipedia.org/wiki/Radiation-absorbent_material

    An RF anechoic chamber used for EMC testing. In materials science, radiation-absorbent material (RAM) is a material which has been specially designed and shaped to absorb incident RF radiation (also known as non-ionising radiation), as effectively as possible, from as many incident directions as possible.

    The U.S. Army Research Office is currently funding research into using MR fluid to enhance body armor. In 2003, researchers stated they were five to ten years away from making the fluid bullet resistant. [14] In addition, HMMWVs, and various other all-terrain vehicles employ dynamic MR shock absorbers and/or dampers.

  9. Talk:Ferrofluid - Wikipedia

    en.wikipedia.org/wiki/Talk:Ferrofluid

    Making a stable ferrofluid requires solving of two problems. The first problem is settling of the particles in a magnetic or gravitational field. This problem is solved by making the magnetic particles very small, typically 10nm or smaller so that they can be kept in suspension by Brownian motion.
