Copper(I) scorpionate complexes and their application in palladium-mediated [(11)C]carbonylation reactions.

5 May 2009 Solutions of copper(I) tris(pyrazolyl)borate complexes have been used to greatly improve the solubility of [(11)C]carbon monoxide, enabling it to be used in low-pressure, 'one-pot' palladium-mediated carbonylation reactions to form ... Read more...

Nickel-based Enzyme Systems.

8 Apr 2009 Of the eight known nickel enzymes, all but glyoxylase I catalyze the use and/or production of gases central to the global carbon, nitrogen, and oxygen cycles. Nickel appears to have been selected for its plasticity in coordination and redox ... Read more...

MicroGISAXS of Langmuir-Blodgett protein films: effect of temperature on long-range order.

Apr 2009 The grazing-incidence small-angle X-ray scattering technique has been used here with a microfocus beamline (microGISAXS) to study the effect of temperature on the protein reorganization taking place in a Langmuir-Schaefer multilayered enzyme film. ... Read more...
