Chiral transmission
WebChirality / k aɪ ˈ r æ l ɪ t iː / 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 object, such as … Web22 hours ago · LbADH EAG was used to reduce AP, retaining 88.3% of the initial activity after being reused 10 times and maintaining a chiral selectivity of more than 99% for R-alcohol (Supplementary Fig. 41).

WebApr 1, 2024 · Asymmetric transmission (AT) refers to the phenomenon that EM can pass through a special structure plate in one direction and be blocked in the reverse direction. Contrary to the irreversibility of the Faraday effect, AT is produced by the interaction of EM radiation with a unique chiral metamaterials (CMMs) structure [[6], [7], [8] ]. WebNov 21, 2024 · Flexible control of broadband asymmetric transmission (AT) is demonstrated by using a polydimethylsiloxane (PDMS)-based stretchable chiral metamaterial (SCM) in the mid-infrared. The unit cell of the SCM consists of two identical Ω-shaped Au patterns with 180° rotation relative to each other to achieve three-dimensional …
In physics, chirality may be found in the spin of a particle, where the handedness of the object is determined by the direction in which the particle spins. Not to be confused with helicity, which is the projection of the spin along the linear momentum of a subatomic particle, chirality is an intrinsic quantum mechanical property, like spin. Although both chirality and helicity can have left-handed or right-handed properties, only in the massless case are they identical. In particular for … WebMar 22, 2024 · Achieving such high efficiency of chiral transmission from the point chiral auxiliaries to the supramolecular assemblies, aside from its remarkable elegance, demonstrates the power of judicious ligand design in the synthesis of …
