Sensors and Actuators A: Physical, 2000
The paper presents a non-conventional actuator with magnetic fluid, generating low forces and very small displacements, controlled by an electric current. A comparative study of the two versions is performed by means of the transfer characteristics. The device might be used in the fine control of some small mechanisms (e.g., the blades of the pneumatic

Thermosensitive magnetic fluids
Journal of Physics: Condensed Matter, 2006Magnetic core–shell particles were synthesized by the attachment of a polymeric brush on the surface of magnetite nanoparticles. The hybrid particles are well dispersible in good solvents for the polymeric shell and form thermoreversible magnetic fluids in carrier fluids with a critical solution behaviour.

Transactions of the American Institute of Electrical Engineers, 1948
A new type of magnetic fluid and several classes of new devices utilizing this fluid have been developed at the National Bureau of Standards. One application of this fluid has been in electromagnetic clutches, but the electro-magnetically controlled mixture offers promise for other uses also.

Journal of Magnetism and Magnetic Materials, 1999
The paper presents a series of theoretical and experimental results concerning the influence of an exterior magnetic field of various configurations and intensities over a power dissipated by a disk brake in magnetic liquid. The formula of the dissipated power and the influence of magnetic field over this for regimes of laminar and turbulent flow of ...

Raman spectroscopy in magnetic fluids
Biomolecular Engineering, 2001In this work Raman spectroscopy was used to investigate uncoated magnetic fluids (UMF's) and coated magnetic fluids (CMF's). The coating agents were N-oleoylsarcosine, dodecanoic acid, and ethoxylated polyalcohol. The Raman probe is the hydroxyl (OH) group chemisorbed at the magnetic nanoparticle surface and the measurements were performed in the ...

Eric Rohmerâs Magnetic Fluid
2014One of the most delightful moments in the exceedingly delightful oeuvre of Eric Rohmer turns out as well to be among the most perplexing. Sitting at a cafe table one afternoon, Frederic (Bernard Verley), whose voiceover narrates L’Amour l’apres-midi (1972), has a fantasy.
