چکیده

Dechlorination reactions at sp(2) C-Cl bonds by a pentaphosphino zero-valent iron (ZVI) complex are proposed to follow an oxidative addition, β-Cl-elimination pathway en route to iron-chloride, iron-hydride and iron-acetylide products, the distribution being dependent on the nature of alkyne produced.

Citrate-mediated iron uptake in Pseudomonas aeruginosa: involvement of the citrate-inducible FecA receptor and the FeoB ferrous iron transporter.

In an attempt to identify components of a ferric citrate uptake system in Pseudomonas aeruginosa, a mutant library of a siderophore-deficient strain (IA614) was constructed and screened for defects in citrate-promoted growth in an Fe-restricted medium. A mutant disrupted in gene PA3901, encoding a homologue of the outer-membrane ferric citrate receptor, FecA, of Escherichia coli (FecA(E.c.)), w...

Oscillatory magnetic anisotropy originating from quantum well states in Fe films.

The magnetic anisotropy of Fe film grown on vicinal Ag(1,1,10) surfaces was studied with the in situ magneto-optic Kerr effect. Below 200 K, strong oscillations of the uniaxial magnetic anisotropy as a function of Fe thickness with a period of 5.7 monolayers are found, which can even cause the easy magnetization axis to oscillate between perpendicular and parallel to the steps. Such novel oscil...

Optical reflectance anisotropy of buried Fe nanostructures on vicinal W(110).

The optical anisotropy of Au protected Fe layers grown on a vicinal W(110) surface has been investigated using reflectance anisotropy spectroscopy (RAS). Iron nanostripes formed at submonolayer coverage, as well as Fe layers up to 3 ML coverage, were protected by 12 and 16 nm gold caps and measured ex situ under ambient conditions. The RAS is dominated by structures originating in the interfaci...

KCl Promoted Cobalt-iron Nanocatalysts Supported on Silica: Catalytic Performance and Characterization in Fischer-Tropsch Synthesis

The SiO2 supported cobalt-iron nano catalysts were prepared by the sol-gel method. This research investigated the effects of (Co/Fe) wt.%, different Co/Fe ratio at different temperature and loading of KCl wt.% for Fisher-Tropsch synthesis (FTS). The results were showed that the catalyst containing 50 wt.% (Co/Fe)/SiO2 (Co/Fe ratio is 70/30) which promoted with 0.6 wt.% KCl is an optimal nano ca...

Modelling of Protective Mechanism of Iron(II)-polyphenol Binding with OH-related Molecular Descriptors

The linear models for the calculation of pIC50, pKa1 and Epa for 12 polyphenolic compounds (catechins, flavonols, catechol and gallol derivatives) were developed. As descriptors we used the number of vicinal (Nv) and non-vicinal (Nnv) OH groups, as well as the number of OH vicinal pairs as possible Fe2+ chelate sites (Nch). The models gave r ˃ 0.9 and standard errors of 0.13, 0.26 and 0.04 for ...
