Chiral Symmetry Breaking in Magnetoelectrochemical Etching with Chloride Additives

Magnetoelectrolysis (electrolysis under magnetic fields) produces chiral surfaces on metal thin films, which can recognize the enantiomers of amino acids. Here, the chiral surface formation on copper films is reported in magnetoelectrochemical etching (MEE) at 5T with chloride additives. In the abse...

In the absence of additives, the surface chirality signs of MEE films depended on the magnetic field polarity.
