Spin-dependent electrochemistry: Enantio-selectivity driven by chiral-induced spin selectivity effect
Spin-Dependent Electrochemistry (SDE) is a new paradigm in electrochemistry where the electrochemical response of a chiral electrode|solution interface is studied as a function of spin-polarized current. In this work, the SDE concept is further developed exploring the use of the “chiral imprinting”...
