A novel magnetohydrodynamic experiment: step-rotation of a nematic subject to a magnetic field

Article Abstract:

The time-dependent behavior of the director following the step-rotation of a nematic sample subject to a static magnetic field is studied. The director orientation is monitored using ESR spectroscopy, and a model-independent analysis of the spectra to yield the distribution function for the director with respect to the magnetic field has been developed.

Magnetic field effect on autocatalysis: Ag and Cu in concentrated nitric acid

Article Abstract:

The partial suppression of corrosion of Ag and Cu in concentrated nitric acid solution by a magnetic field up to 5 T was studied. The corrosion current density of these metals was found to diminish with magnet field and rotation speed in a rotating disk electrode experiment.

Magnetic field effects on copper electrolysis

Article Abstract:

The effect of a static magnetic field, B, on the electrolysis of copper in aqueous solution is investigated. The linear sweep voltammetry, impedance spectroscopy, chronoamperometry, rotating disk voltammetry, and analysis of fractal growth patterns are used for the purpose.
