http://www.ichacha.net/chiral.html WebThe use of a chiral additive such as l-cysteine or d-cysteine has been used to manipulate the handedness of the resulting nanoparticles (Fig. 1a-i, ii). 30 Because of the chiral geometry, the distributions of the electric field and magnetic field differ distinctly depending on the handedness of the incident circularly polarized light (Fig. 1a-iii).

Contrary to your claim, chirality is in fact a purely mathematical conception, while handedness has also physical interpretation. In elementary particle physics, chirality just defines the transformation law of the given field under the Lorentz group. For example, Dirac spinor is composed from two 2-component spinors … Chirality /kaɪˈrælɪtiː/ is a property of asymmetry important in several branches of science. The word chirality is derived from the Greek χειρ (kheir), "hand", a familiar chiral object. An object or a system is chiral if it is distinguishable from its mirror image; that is, it cannot be superimposed onto it. Conversely, a mirror image of an achiral obj… binley village coventry
