Chiral handedness翻译
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).

WebMay 24, 2024 · Precisely and conveniently controlling the handedness and magnitude of circularly polarized luminescence (CPL) is a key issue in developing CPL-active materials. In this work, a series of chiral helical polyacetylenes bearing pendant pyrene groups were synthesized. CPL inversion occurred when the polymer solutions fabricated into thin solid … WebThe configuration of such a molecular unit is chiral, and the structure may exist in either a right-handed configuration or a left-handed configuration (one the mirror image of the …

Based on this observation ... In chemistry, a molecule or ion is called chiral if it cannot be superposed on its mirror image by any combination of rotations, translations, and some conformational changes. This geometric property is called chirality (/kaɪˈrælɪti/).

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… WebHand-Schuller-Christian disease in a septuagenarian. h开头的单词 hypoxic stress hysteron proteron hypovolemic shock hypoxanthine-guanine phosphoribosyltransferase …
