Active site engineering in UiO-66 type metal-organic frameworks by intentional creation of defects: a theoretical rationalization

The catalytic activity of the Zr-benzenedicarboxylate (Zr-BDC) UiO-66 can be drastically increased if some BDC linkers are missing, as this removes the full coordination of the framework metal ions. As a result, metal centers become more accessible and ... [Published RSC - Oct 17 2014]

Quotes

According to the news editors, the research concluded: "A similar orientation of the superoxide ligand in the putative Fe(III)-superoxo reaction intermediate would promote the attack of the distal oxygen atom on the sulfur of substrate Cys."
...insights into the ultrastructural changes in an intracellular machine associated with the acquisition of resistance to the antibiotic erythromycin. "A better understanding of this mechanism is an important step towards the development of new and more potent antibiotics" Wilson says
"It's very difficult. These decisions to actually downsize and to make sure that each mine stays competitive, because if a mine's not competitive, then job security is not present."
