Cascade Promotion of Gas Separation Performances in CMS Membranes: MOFs With Functional Groups and Loaded Noble Metals

Advanced Science, EarlyView.
Novel mixed‐matrix carbon molecular sieve (MMCMS) membranes are fabricated via employing palladium‐doped carboxyl‐functionalized UiO‐66 (Pd/UiO66‐COOH)/polyimide MMM as precursor. The synergistic effect of decarboxylation‐induced thermally cross‐linking and catalytic graphitization of Pd promoted the formation of more ordered Langmuir domains, thereby ...

Biochemical Characterization and Phylogenetic Analysis of the Virulence Factor Lysine Decarboxylase From Vibrio vulnificus

Frontiers in Microbiology, 2018
Cadaverine is produced in organisms from the amino acid lysine in a decarboxylation reaction catalyzed by lysine decarboxylase (EC 4.1.1.18). The inducible lysine decarboxylase CadA plays a vital role in acid stress response for enteric bacteria.
