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 ...
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]
In this week's episode of Experimental, learn how to make magnetic ferrofluid dance unlike any other liquid!
Toner using plant-derived plastic also exists as an alternative to petroleum plastic. [2] Toner particles are melted by the heat of the fuser, and are thus bonded to the paper. In earlier photocopiers, this low-cost carbon toner was poured by the user from a bottle into a reservoir in the machine [citation needed].
Ferrofluidic is the brand name of a staged magnetic liquid rotary sealing mechanism made by the Ferrotec Corporation. Ferrofluidic seals, also known as magnetic liquid rotary seals, are employed in various rotating equipment to facilitate rotary motion while ensuring a hermetic seal.
The teenager was exploring a Gold Rush-era mine shaft that was about six feet deep and 30 feet back when he fell and became stuck. After about 15 minutes, a friend who was with the teen called for ...
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.
