Optical Chirality Enhancement in Twisted Arrays of Plasmonic Nano-rods

An important property of electromagnetic fields, which arises from the interaction between fields and chiral molecules, is called optical chirality. By enhancing this field property, while maintaining constant input power, we are able to increase absorption of circularly polarized light by chiral molecules of a certain handedness. This enhancement is achieved through the use of achiral plasmoni...

Chirality in Metric Spaces

A definition of chirality based on group theory is presented. It is shown to be equivalent to the usual one in the case of Euclidean spaces, and it permits to define chirality in metric spaces which are not Euclidean. 2000 MSC code: 58D19 ; PACS code: 02.20.Bb

Drug chirality in anesthesia.

MORE than one-third of all synthetic drugs are chiral and are marketed as racemates, 1:1 mixtures of two types of molecules bearing identical chemical constitution and atomic connections but with a different spatial orientation of their constituent atoms. Drug receptors may discriminate between stereoisomers in several ways; binding may favor one form over the other, and to a degree varying wit...

Chirality in Liquid Crystals

Chirality in chemistry.

The useful terms chiral and chirality were coined by W. H. Thompson (Lord Kelvin) in 1884 and are derived from cheir, the Greek word for a hand, indeed one of the most familiar chiral objects. The simplest chiral object of the three-dimensional perceptual space is, however, the chiral three-dimensional simplex, the irregular tetrahedron. As early as 1827 the famous German mathematician August F...
