Chloride retention mechanism of coral sand cement stones modified by graphene oxide
工程科学学报, 2022 In the marine environment far away from the mainland, the coral sand foundation can be improved by injecting the cement grout with a very small amount of graphene oxide (GO) through grouting or mixing piles and other processes, which can greatly increase

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
FEBS Letters, EarlyView.Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.
