The Active Site Structure of Heme a3 3+-C≡N-CuB2+ of Cytochrome aa 3 Oxidase as Revealed from Resonance Raman Scattering
(2003)Resonance Raman and FTIR spectroscopies have been employed to investigate the structure of the heme a3-C≡N-CuB complex of oxidized cytochrome aa3 oxidase. The characterization of this complex is essential since a central ...

Adaptive VN/Ag nanocomposite coatings with lubricious behavior from 25 to 1000 °c
(2010)A two-phase nanocomposite coating that consists of inclusions of silver in a vanadium nitride matrix (VN/Ag) was investigated as a potential adaptive coating with a reduced friction coefficient from 25 to 1000 °C. This ...

Direct detection of Fe(IV)=O intermediates in the cytochrome aa3 oxidase from Paracoccus denitrificans[H2O2 reaction
(2003)We report the first evidence for the formation of the "607- and 580-nm forms" in the cytochrome oxidase aa3/H2O2 reaction without the involvement of tyrosine 280. The pKa of the 607-580-nm transition is 7.5. The 607-nm ...

The effect of calcination temperature on the oxygen storage and release properties of CeO2 and Ce-Zr-O metal oxides modified by phosphorus incorporation
(2005)The present work reports on the effects of calcination temperature (T c) on the oxygen storage and release properties of CeO2 and Ce0.8Zr0.2O2 solids deliberately contaminated with CePO4. Pulsed-feed and stepped-feed dynamic ...

Novel Fe-Mn-Zn-Ti-O mixed-metal oxides for the low-temperature removal of H2S from gas streams in the presence of H2, CO 2, and H2O
(2005)The efficiency of Fe-Mn-Zn-Ti-O mixed-metal oxides of varying composition prepared by sol-gel methods toward removal of H2S from a gas mixture containing 0.06 vol% H2S, 25 vol% H2, 7.5 vol% CO 2, and 1-3 vol% H2O was studied ...

The production and decay kinetics of CIOO in water and freon-11: A time-resolved resonance Raman study
(2001)The production and decay kinetics of ClOO in water and freon-11 were studied using time-resolved resonance Raman (TRRR) spectroscopy. The formation of ClOO following OClO photoexcitation at 390 nm was investigated using ...
