Research reveals a new mechanism to transfer chirality between molecules in the nanoscale field
If we compare the right to the left hand, we can see these are specular images—that is, like symmetrical shapes reflected in a mirror—and they cannot superimpose on each other. This property is chirality, a feature of ...
