Characterization of perovskite powders for cathode and oxygen membranes made by different synthesis routes

Jan Van Herle, Philippe Buffat, Sébastien Vaucher, Elena Suvorova Buffat, Nicolas Xanthopoulos

Strontium lanthanum manganite (LSM) and lanthanum ferrite (LSF) perovskite cathode and oxygen membrane materials were synthesized using different techniques: spray pyrolysis, a modified citrate route, oxalate and carbonate co-precipitations. The use of Ca, ...

Time-resolved visible and infrared study of the Cyano complexes of Myoglobin and of Hemoglobin I from Lucina pectinata

Majed Chergui, Frank van Mourik, Alejandro Gonzalez Gonzalez, Luigi Bonacina

The dynamics of the ferric CN complexes of the heme proteins Myoglobin and Hb I from the clam Lucina pectinata upon Soret band excitation is monitored using IR and broad band visible pump-probe spectroscopy. The transient response in the UV-vis spectral re ...

Synthesis and characterization of ionic liquids incorporating the nitrile functionality

Paul Joseph Dyson, Zhaofu Fei, Dongbin Zhao

A series of imidazolium salts with the nitrile functional group attached to the alkyl side chain, viz. [C(n)CNmim][X] (where C(n)CNmim is the 1-alkylnitrile-3-methylimidazolium cation and C-n = (CH2)(n), n = 1-4; X = Cl, PF6, and BF4) and [C(3)CNdmim][X] ( ...

The complex between hydrogenase-maturation proteins HypC and HypD is an intermediate in the supply of cyanide to the active site iron of [NiFe]-hydrogenases

Melanie Blokesch

Carbamoylphosphate has been shown to be the educt for the synthesis of the CN ligands of the NiFe metal centre of hydrogenases from Escherichia coli. In the absence of carbamoylphosphate, cells accumulate a complex of two hydrogenase maturation proteins, n ...

On the reactivity of the iminodiphosphane C6H4(o-CN)N=PPh2-PPh2: Fragmentation versus isomerisation

Paul Joseph Dyson, Zhaofu Fei

The reactivity of the iminodiphosphane C6H4(o-CN)N= PPh2-PPh2, which contains an N=P-P unit, has been investigated. Reaction with small molecules, [viz. H2O/O-2, H2O2, CH3OH, C6H4(o-CN)NH2] and elemental sulfur result in cleavage of the P-P bond to give am ...

Synthesis and structural elucidation of a "free" phosphinoamide anion

Paul Joseph Dyson, Zhaofu Fei

The reaction of the aminophosphane C6H4(o-CN)NHPPh2 with elemental potassium in the presence of 18-crown-6 affords the phosphinoamide-containing complex [C6H4(o-CN)N-PPh2(THF)(18-Crown-6)K] which has been fully characterised in solution and the solid state ...

A homologous series of O- and N-functionalized 2,2-difluoro-1,3-benzodioxoles: An exercise in organometallic methodology

The conversion of 2,2-difluoro-1,3-benzodioxole, an exceptionally acidic arene, via a 4-lithiated intermediate into more than three dozen new derivs. was conceived as a case study. The lithiated species was trapped by C0-electrophiles (4-toluenesulfonyl az ...

Influence of the functional group on the synthesis of aminophosphines, diphosphinoamines and iminobiphosphines

Paul Joseph Dyson, Zhaofu Fei

The reaction of the anilines RNH2 [R = C6H4(o-CN), C6H4(p-CN), C6H4(m-CN), C6H4(o-C6H5), C6F5 and C6H4(o-CF3)] with Ph2PCl and inorganic or organic bases in differing stoichiometry and in different solvents has been studied. The electronic properties and s ...
