English: Ferrofluid has been submersed in sugar water. Sugar has been added to increase the density of the water to the point where the ferrofluid appears weightless. Ferrofluid in Simulated Microgravity - Alexander O.D. Lorimer
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 ...
Magnetic droplets, in the context of droplet-based microfluidics, are microliter size droplets that are either composed of ferrofluids or contain some magnetic component that allows for manipulation via an applied magnetic field. Ferrofluids are homogenous mixtures of colloidal solutions of magnetic nanoparticles in a liquid carrier. [80]
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.
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.
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]
A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.
