An investigation of the nitroxide-mediated preirradiation grafting of styrene onto PFA

Simultaneous and preirradiation grafting of styrene onto fluorinated polyolefins does not enable control of the molecular weights or polydispersities of the styrene grafts. The nitroxide-mediated grafting of styrene onto PFA with TEMPO and TEISO using a preirradiation method has been investigated as a means of controlling the graft properties and especially to produce grafts with improved suitability for SPOC. The yields of graft were found to be in the range 15-20% for nitroxide concentrations between 5 x 10(-3) and 2 x 10(-2) M and were similar for the two nitroxides studied. Raman mapping was used to obtain the depth profile for the styrene grafts. The grafts were found to be principally located within the PFA substrate, and little graft was formed at the PFA surface. Fmoc loading tests were performed to assess the suitability of the grafted PFA as a support for SPOC, but these showed no significant loading was achieved, thus indicating that the graft properties are not suitable for SPOC. However, the study has important implications for the applications of PFA-grafted polymers in other areas, such as chemically resistant ion-exchange and separation membranes.

Fluorinated-plasma modification of polyetherimide films

Ultem 1000 polyetherimide films prepared by cast-evaporating technique were covered with a 1H,1H,2H-tridecafluoro-oct-1-ene (PFO) plasma-polymerized layer. The effects of the plasma exposure time on the surface composition were studied by X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, and surface energy analysis. The surface topography of the plasma layer was deduced from scanning electron microscopy. The F/C ratio for plasma-polymerized PFO under the input RF power of 50 W can be as high as 1.30 for 480 s and similar to 0.4-2 at % of oxygen was detected, resulting from the reaction of long-lived radicals in the plasma polymer with atmospheric oxygen. The plasma deposition of fluorocarbon coating from plasma PFO reduces the surface energy from 46 to 18.3 mJ m(-2). (c) 2006 Wiley Periodicals, Inc.

Structure of the active site of sulfite dehydrogenase from Starkeya novella

In this paper, we report the results of molybdenum K-edge X-ray absorption studies performed on the oxidized and reduced active sites of the sulfite dehydrogenase from Starkeya novella. Our results provide the first direct structural information on the active site of the oxidized form of this enzyme and confirm the conclusions derived from protein crystallography that the molybdenum coordination is analogous to that of the sulfite oxidases. The molybdenum atom of the oxidized enzyme is bound by two Mo=O ligands at 1.73 angstrom and three thiolate Mo-S ligands at 2.42 angstrom, whereas the reduced enzyme has one oxo at 1.74 angstrom, one long oxygen at 2.19 angstrom (characteristic of Mo-OH2), and three Mo-S ligands at 2.40 angstrom.
