Advances in medicinal inorganic chemistry: Exploiting the biological activity of metal arene complexes
… is reported, alongside in-depth studies on their chemistry in solution, and their mode of action within the cell. The metal ion (Ru, Os, Rh, Ir) can strongly alter the reactivity of the complexes in solution, and therefore, their biological activity. This work gives insights into our understanding …

Mass transport in metal-organic frameworks as a limiting step in size-selective oligomerization
… porous materials at the interface of organic and inorganic chemistry that have been applied in gas absorption and storage systems, thin-film devices, and heterogeneous catalysts. While numerous examples of size-exclusive catalysis have been reported, to our knowledge no reports of size-selective …

Metal sequestration of the host-defense protein human calprotectin
… In our work, we investigate the coordination chemistry and antimicrobial activity of human CP. We discovered that CP also has the capacity to scavenge Fe(II) from microbes by chelating this metal ion with high affinity at its unusual hexahistidine (His 6) coordination motif, and we show that …

Microchemical phase characterization of petroleum coke gasification slags
The inorganic chemistries of coal and petroleum differ because of their disparate geologic environments of formation, the physical state of the fuels, and the type and quantity of minerals and organic compounds in the fuels. Commercial coals typically contain 2 to 25% ash (average ~ 10%) while …
