Chirality control
WebChirality control of inorganic materials and metals by peptides or amino acids Hyeohn Kim,† Sang Won Im,† Ryeong Myeong Kim,† Nam Heon Cho, Hye-Eun Lee, Hyo-Yong Ahn and Ki Tae Nam * Chirality exists everywhere in nature and may be one of the most important features in biological systems. WebApr 13, 2024 · Nature is not always ambidextrous: it sometimes favors one hand, e.g., in the chirality of amino acids. In a recent issue of Cell Reports Physical Science, Wang and Sugiyama demonstrate the transformation of a crystal from achiral to chiral, where the hand of the crystal can be selected by the hand of circularly polarized light.

WebHerein, we show that it is possible to control the chirality of lead bromide perovskites by incorporating enantiopure (R or S) or racemic (RS) β-methylphenethylammonium. The incorporation of such cations allows us to control the chirality of the resulting materials and yields the first examples of 2D chiral perovskites that emit white light ... data center policy 2020WebJun 6, 2016 · Significance. Exceptional points (EPs) emerge when a system with loss or gain is tuned such that its eigenvalues and the corresponding eigenstates coalesce. By operating close to two EPs, we achieved a dynamic control of the rotation direction of light in a whispering-gallery-mode (WGM) resonator.
