“…11,12 Furthermore, a well-regulated local convection may produce a chiral aggregation of achiral molecules, or induce any chirality in the reaction products conducted in a capillary, as suggested at the rotated liquid-liquid interface, 37 in the electrode surface under a magnetic field, 38 and under the application of rotational and magnetic forces. 39 …”

The electromagnetophoretic behavior of organic droplets in an electrolyte solution was investigated in a silica capillary cell using a superconducting bulk magnet (3.5 T) and a magnetic circuit (2.7 T). The initially dispersed emulsion droplets of dodecane migrated to the wall of the capillary, responding to the direction of an electric current, and coalesced to form smaller and larger droplets after some repeated migrations. When the electric current was applied continuously, the larger droplets became arranged with regular intervals on the wall, and smaller droplets rotated around the larger droplets. These interesting behaviors were analyzed while taking into account the local electric current density determined by the flow velocity of the ionic current around a droplet, which was lowest on the electrode sides of the droplet. The difference in the local electric current density generated the Lorentz-force difference in the medium, which lead to local microconvection around the droplet, and also the alignment of larger droplets by a repelling effect between the adjacent microconvections.

“…21A). 259 The enantiomeric excess (ee) ratio in the voltammograms, which is defined as ee = ( i l p − i d p )/( i l p + i d p ), where i l p and i d p represent the peak currents of l - and d -TA, respectively, gave positive values during 30–50 s deposition time (with a maximum value of 0.5 at 40 s), where the steady self-organized state of the MHD flows formed on the surface of the Cu film electrode. These facts implied that the self-organized state of the micro-MHD and the vertical MHD flows are crucial for the formation of chiral Cu film surfaces (Fig.…”

“…21B). 259 Furthermore, they found that the specific adsorption of chloride ions on the film surfaces and the direction of the magnetic field of 5 T had a drastic influence on the chiral property of the Cu film, which was measured by the voltammetric ee ratio of l - and d -alanine. They suggested that not only the micro-MHD vortices but also the rate-limiting steps of Cu dislocation are responsible for the chiral surface formation.…”
