Some sources use the terms stereocenter , stereogenic center , stereogenic atom or stereogen to refer exclusively to a chirality center, [15] [17] [19] while others use the terms more broadly to refer also to centers that result in diastereomers (stereoisomers that are not enantiomers).

"Webchirality can lead to exceptionally strong circular dichroism, optical activity and asymmetric transmission, indistinguishable from those exhibited by conventional 3D- and 2D-chiral systems. Circular dichroism and birefringence due to extrinsic 3D chirality were recently observed in metamaterials by our group for the ﬁrst time [28, 29]. " - Is a screw chiral
