Optically active chiral cuo “nanoflowers”
WebApr 15, 2024 · Epoxide hydrolases are attractive and industrially important biocatalysts. They can catalyze the enantioselective hydrolysis of epoxides to the corresponding diols as chiral building blocks for bioactive compounds and drugs. In this review article, we discuss the state of the art and development potential of epoxide hydrolases as biocatalysts … WebApr 27, 2024 · In this work, a facile chemical method to deposit chiral CuO nanoflowers on an activated quartz substrate is demonstrated. Three levels of chirality in CuO nanofilms are demostrated by structural analysis: tertiary helically arranged “nanopetals” assembled from secondary helically stacking “nanoplates.”
