Optically active chiral
WebApr 7, 2024 · A chiral dopant ((R)-BB, 0.05 or 0.25 wt%) was also added, in order to induce with a pitch of 44.7 or 8.9 µm. Once introduced into a 20 µm thick electro-optical cell, the chiral nematic helices experience a confinement ratio of ≈0.5 and ≈2.2, which leads to the formation of HH and SFLH patterns, respectively, once low voltage is applied. WebAcetoin (AC) is an important platform bulk chemical with versatile applications. It exists in two stereoisomeric forms: (3R)-AC and (3S)-AC. Both stereoisomers could be potentially applied in the pharmaceutical industry, agriculture, and in optically active α-hydroxyketone derivative synthesis. Chiral AC production has recently become a new research focus in …

This is a result of the action of chiral catalysts we call enzymes, and reflects the inherently chiral nature of life itself. ...
WebNov 19, 2024 · Chiral photonic crystals have been a widely investigated topic in chemistry, physics and biology. Till now, the research about chiral photonic crystals has been conducted on the objects of helical structures, while the chiral photonic crystals made of periodic chiral media remain unexplored experimentally. In this work, we have … WebApr 22, 2024 · Chiral electromagnetism, often referred to as optical activity (OA), has two main properties that describe the way a wave interacts with a given chiral medium. The first is optical rotatory dispersion (ORD) in which the polarization of a wave is rotated as it passes through a chiral medium.
WebOptically active molecules can be described by their chirality, or the asymmetry in a molecule’s structure. Chiral molecules exhibit circular birefringence or optical rotation, where the velocity of the light passing through an optically active medium will differ depending on the medium’s refractive index.
