  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] Each magnetic particle is thoroughly coated with a surfactant to inhibit clumping. Large ferromagnetic particles can be ...

  3. Ferrofluidic seal - Wikipedia

    en.wikipedia.org/wiki/Ferrofluidic_seal

    Magnetic liquid rotary seals operate with little maintenance and minimal leakage in a range of applications. Ferrofluid-based seals used in industrial and scientific applications are most often packaged in mechanical seal assemblies called rotary feed-throughs, which also contain a central shaft, ball bearings, and outer housing.

  4. 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.

  5. Magnetorheological fluid - Wikipedia

    en.wikipedia.org/wiki/Magnetorheological_fluid

    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]

  6. Sachiko Kodama - Wikipedia

    en.wikipedia.org/wiki/Sachiko_Kodama

    Sachiko Kodama (born 1970) is a Japanese artist. She is best known for her artwork using ferrofluid, a dark colloidal suspension of magnetic nano-particles dispersed in solution which remains strongly magnetic in its fluid. [1]

  8. Petcube - Wikipedia

    en.wikipedia.org/wiki/Petcube

    Petcube offers three devices: Petcube Camera, Petcube Bites with camera and a treat dispenser, and Petcube Play which features a laser pointer to keep the pet entertained (distracted) while the owner is away. [9] The devices can stream and record video, toss treats, allow users to communicate with a pet two-way, and connect to Amazon Alexa ...

  9. Fionn Ferreira - Wikipedia

    en.wikipedia.org/wiki/Fionn_Ferreira

    Ferreira designed and tested a method to remove microplastics from water, following what he described as thousands of failed attempts. Ferreira has stated that he was inspired by an article by Fermilab physicist Arden Warner, who developed a new approach to cleaning up oil spills, using magnetic principles, [10] and made a device that uses a magnet-based method to remove the particles from ...
