Detection of the His-heme Fe2+-NO species in the reduction of NO to N2O by ba3-oxidase from thermus thermophilus
(2005)Reaction pathways in the enzymatic formation and cleavage of the N-N and N-O bonds, respectively, are difficult to verify without the structure of the intermediates, but we now have such information on the heme a3 2+-NO ...

Effect of halogen substitution on o-Phenylenebiscarbene
(2005)The effect of halogen (F, Cl and Br) perturbation on the geometries and relative energies of five electronic states (one quintet, two triplets and two singlets) of o-phenylenebiscarbene (1-H) is examined computationally ...

The effect of sorbed toluene on the surface properties of calcium hydroxide
(1998)The surface properties of commercial grade calcium hydroxide were studied by nitrogen adsorption isotherm analysis, FTIR spectroscopy (KBr transmission and reflectance) and TGA analysis before and after toluene adsorption. ...

The effects of P-poisoning of CexZr1-xO2 on the transient oxygen storage and release kinetics
(2013)The present work reports on the investigation of the effects of chemical poisoning of CexZr1-xO2 solids by phosphorous (P) on the kinetics of oxygen storage and release (OSR) of the thus derived P-contaminated solids, as ...

Fourier transform infrared evidence for a ferric six-coordinate nitrosylheme b3 complex of cytochrome cbb3 oxidase from Pseudomonas stutzeri at ambient temperature
(2002)We report the first vibrational study of NO bound to an oxidized heme-copper oxidase. Cytochrome cbb3 oxidase from P. stutzeri reduces both O2 and NO to H2O and N2O, respectively. The ferric nitrosyl complex of cbb3 exhibits ...

Near-monodisperse α-hydroxy and α,ω-dihydroxy amine-based polymers: Synthesis and characterization
(1999)α-Hydroxy and α,ω-dihydroxy polymers of 2-(dimethylamino)ethyl methacrylate (DMAEMA) of various molecular weights were synthesized by group transfer polymerization (GTP) in tetrahydrofuran (THF), using 1-methoxy-1-(trime ...

Reaction of tetracyanoethylene with SCl1
(2000)The chloride ion catalysed addition of SCl2 to TCNE gives the 4-dicyanomethylene-l,2,6-thiadiazine 2 (60%) with two minor products (5%) of extensive molecular rearrangement, the pyrimidine 4 and the pyrroloimidazothiadiazine ...

Singlet hydrocarbon carbenes with high barriers toward isomerization: A computational investigation
(2003)A prerequisite for a stable singlet hydrocarbon carbene is the existence of high barriers toward isomerization. Four derivatives of cyclopentylidene (1-4) with rigid and varying carbon cages are examined computationally ...

The structure of the hyponitrite species in a heme Fe-Cu binuclear center
(2007)NO laughing matter: The enzymatic production of laughing gas (N 2O) from two molecules of NO requires the formation of the N-N bond and the subsequent cleavage of the N-OH bond. Resonance Raman spectroscopic studies have ...

A systematic evaluation of the interplay of weak and strong supramolecular interactions in a series of Co(II) and Zn(II) complexes tuned by ligand modification
(2012)A systematic investigation on a designed series of 21 transition metal complexes has been carried out with the intention to explore and assess the relative strength and the way in which intermolecular interactions, namely, ...
