摘要：

The action of chiral modifiers like cinchonine and cinchonidine in facilitating enationselectivity in heterogeneous catalysis is investigated using a combination of electrochemical and scanning probe methods. The surface chirality of corner kink sites is suggested as being crucial for chirality recognition at supported catalyst nanoparticles. Other aspects of chirality in relation to one, two, three and four dimensions are also discussed.
