Niobium uptake and release by bacterial ferric ion binding protein [PDF]

, 2010
Ferric ion binding proteins (Fbps) transport FeIII across the periplasm and are vital for the virulence of many Gram negative bacteria. Iron(III) is tightly bound in a hinged binding cleft with octahedral coordination geometry involving binding to ...

Crossing and Anticrossing of Exchange‐Coupled Molecular Spin Excitation Energy Levels

Small, EarlyView.
Orientation matters: The excitation energy levels of exchange‐coupled spins of two nickelocene molecules anchored to superconducting electrodes are explored via inelastic electron tunneling spectroscopy. Depending on the tilt angle of the single‐molecule magnetic probe the levels cross or exhibit avoided crossing. Abstract The superconducting Pb tip of

Advancing Single‐Walled Carbon Nanotubes toward Next‐Generation Electronic Materials: The Critical Roles of Purity and Processability

Small Methods, EarlyView.
Single‐walled carbon nanotubes (SWNTs) are promising for a wide range of applications. In particular, their exceptional electrical conductivity positions them as potential alternatives to traditional metal conductors. This review identifies the key mechanisms governing their conductivity within composites and proposes practical pathways for translating

Olefin Polymerizations Oriented by Rational Designs of Group‐13 Compounds

The Chemical Record, EarlyView.
In coordination olefin polymerization chemistry, boron and aluminum compounds play important roles in both catalyst components and monomers. This personal account introduces our recent progress on the development of catalyst systems featured by the design of group‐13 counteranions, as well as the application of boronic acid‐crosslinked polyolefins to ...

Testing DFT ability to predict the stereoselectivity of group 4 metallocenes in propylene polymerization [PDF]

Polyolefins Journal, 2014
In this study we have tested the ability of a standard DFT computational protocol to reproduce the experimentally obtained stereoselectivity of 26 different C2-symmetric zirconocene catalysts active in propylene polymerization.

Versatile Coordination of Cyclopentadienyl-Arene Ligands and Its Role in Titanium-Catalyzed Ethylene Trimerization [PDF]

, 2009
Cationic titanium(IV) complexes with ansa-(η5-cyclopentadienyl,η6-arene) ligands were synthesized and characterized by X-ray crystallography. The strength of the metal-arene interaction in these systems was studied by variable-temperature NMR ...
