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]
In this week's episode of Experimental, learn how to make magnetic ferrofluid dance unlike any other liquid!
A ferrofluid mirror is controlled by a number of actuators, often arranged in a hexagonal array. [3] [4] Pure ferrofluids have low reflectivity, so they must be coated with a reflective layer. Water-based ferrofluids hold the reflective layer effectively, but water evaporates so quickly that the mirror could disappear within hours.
A magnetorheological fluid (MR fluid, or MRF) is a type of smart fluid in a carrier fluid, usually a type of oil. When subjected to a magnetic field, the fluid greatly increases its apparent viscosity, to the point of becoming a viscoelastic solid. [1]
Remanufactured toner and ink cartridges make up 30% of the total printer cartridge market. [citation needed] Remanufactured cartridges are recycled cartridges that have been disassembled, cleaned and tested for quality. Worn or damaged parts are replaced and the cartridge is then re-assembled and refilled with ink.
Almost all model kits on the market were plastic, necessitating paints (the square, glass Testor paint bottles were sold in almost every dime store, department store, hardware store, toy store and hobby store in the US in the 1960s, making them truly ubiquitous) and glues different from those used for wooden models.
Another application of magnetic nanoparticles is in the creation of ferrofluids. These are used in several ways. Ferrofluids can be used for targeted drug delivery in the human body. [78] The magnetization of the particles bound with drug molecules allows "magnetic dragging" of the solution to the desired area of the body.
The surfactant lowers the surface tension between water and oil, making the solution transparent. The water nanodroplets act as nanoreactors for synthesizing nanoparticles. The shape of the water pool is spherical. The size of the nanoparticles will depend on size of the water pool to a great extent.
