WebApr 13, 2024 · There need not have been much circular polarization around to bias the chiral evolution of life given that autocatalysis can amplify a small bias. Chirality attracts much interest not only because of the mystery of biohomochirality but also because of the societal and economic value gained through controlling it. Because the chemical cycles ... WebInspired by the chirality in nature and life, a wide variety of different synthesis strategies have been developed to extend the chiral materials to inorganic materials [330–337]. In this section, some typical inorganic chiral materials, such as zeolites, molecular sieves, SiO 2 , metals, etc., are described on the basis of the corresponding ...
