Ferrofluids, namely stabilized suspensions of small magnetic particles in a non-magnetic solvent have many industrial applications like rotary seals, inertia dampers, magnetic domain detectors, concentration of drugs at body sites etc. (Strand and Kim 1992). Superparamagnetic iron oxides (SPIOs) are used as tracer for the new imaging technique Magnetic Particle Imaging. The stability of ferrofluids for medical application has a great importance, in addition to the particle size.
The behavior of ferrofluid when "dimensionally constrained" like this is quite fascinating. It's also pretty different from ferrofluid that just flows around in three dimensions. We had an exhibit at the Exploratorium that constrained ferrofluid like this, but I don't think we ever figured out just why it behaved as it does.

DChemistry Panel Summary. The Chemistry panel met at the National Academy of Sciences building on February 15-16, 2001. They discussed the similarities and differences between undergraduate educations in biology versus chemistry. Ultra fine precursors for ferrofluid synthesis, belonging to the series, Ni 𝑥 Fe 1-𝑥 Fe 2 O 4 (where `𝑥’ varies from `0’ to `0.6’ in steps of 0.1), were synthesized. Ferrofluids based on these fine particles were prepared with oleic acid as surfactant and kerosene as carrier. Stress is the force per unit area on a body that tends to cause it to change shape.. Stress is a measure of the internal forces in a body between its particles. These internal forces are a reaction to the external forces applied on the body that cause it to separate, compress or slide. External forces are either surface forces or body forces.Stress is the average force per unit area that a ...Uniaxial normal stress. Tensile stress (or tension) is the stress state leading to expansion; that is, the length of a material tends to increase in the tensile direction. The volume of the material stays constant. When equal and opposite forces are applied on a body, then the stress due to this force is called tensile stress. Science isn’t just something you do in a lab or in a classroom.

A ferrofluid or ferromagnetic fluid is a liquid that becomes strongly magnetized in the presence of a magnetic field. A process for making a ferrofluid was invented in 1963 by NASA's Steve Papell to create liquid rocket fuel that could be drawn toward a pump inlet in a weightless environment by applying a magnetic field.
