Abstract:

Carbonyl products were separated and identified in suspensions of rat liver microsomal fractions and in isolated hepatocytes, after stimulation of lipid peroxidation by incubation with the pro-oxidants CCl4 and ADP-iron. The carbonyl products were allowed to react with 2,4-dinitrophenylhydrazine, and the derivatives were extracted and separated by t.l.c. into three zones of non-polar materials, and one fraction of polar derivatives that remained at the origin. Separation of the individual non-polar hydrazones in each zone by h.p.l.c. demonstrated that zone I prepared from microsomal fraction o

Abstract:

The field-dependent viscoelastic and transient behaviours of plate-like-carbonyl-iron-particle-based magnetorheological greases are experimentally investigated in this study. The plate-like carbonyl-iron particles are made from spherical carbonyl-iron particles through a milling process using a rotary ball mill. Several samples of magnetorheological greases consisting of different weight percentages of plate-like carbonyl-iron particles are prepared. The surface microstructures and distributions of the plate-like carbonyl-iron particles in the grease are observed using various types of microsc

Construction of carbon–carbon bonds is one of the most important tools for the synthesis of complex organic molecules. Among multiple possibilities are the carbonyl–alkyne and carbonyl–olefin metathesis reactions, which are used to form new carbon–carbon bonds between carbonyl derivatives and unsaturated organic compounds. As many different approaches have already been established and offer reliable access to C=C bond formation via carbonyl–alkyne and carbonyl–olefin metathesis, focus is now shifting towards cost efficiency, sustainability and environmentally friendly metal catalysts.

Magnetorheological gels typically are colloids of spherical micrometer magnetic particles dispersed in a high-viscosity polymer matrix. However, some major parameters of this kind of mono-disperse magnetorheological gel, such as the shear storage modulus and yield stress, cannot meet the needs of practical engineering application. In this study, a systematic experiment was investigated on the use of dendritic carbonyl iron particles to enhance the comprehensive performance in conventional (microsphere-based) magnetorheological gels formulated in polyurethane matrix.

The 57Fe Mößbauer spectra of mixed ligand complexes of the type trans-Fe(CO)3L1L2 (L1 = triphenylphosphine or triphenylphosphite and L2 = phosphine or phosphite) show a quadrupolesplitting doublet typical of the disubstituted iron carbonyls in trigonal bipyramidal symmetry. The inverse linear dependence of the isomer shifts on the CO stretching frequencies is interpreted on the basis of the strengthening triple-bond nature of the carbonyl ligands with increasing iron-to-phosphorus π-back donation. A linear correlation, with a positive slope, between the isomer shifts and the quadrupole splitti

AbstractReactions of the Collman reagent, Na2[Fe(CO)4]·1.5 dioxane, towards the nitrosyl carbonyls [CoNO(CO)3] and [Fe(NO)2(CO)2] in THF as the solvent at room temperature were investigated. Thereby a quick transfer of one nitrosyl ligand from the nitrosyl carbonyl molecule to the iron carbonyl metalate was observed. The reaction with the cobalt compound afforded in high yields the well-known species [Co(CO)4]− and [FeNO(CO)3]− isolated by addition of two equivalents of [PPN]+Cl− ([PPN]+= bis(triphenylphosphane)iminium cation) and characterized by their known IR spectra, by elemental analysis

Abstract:

This paper focuses on the preliminary characterization of alternative magnetic particles as a replacement for commercial carbonyl iron particles for magnetorheological elastomers (MREs). Magnetite powder (Fe3O4) can be found in electronic waste (E-waste), iron ore as well as toner waste. In this study, three types of powders namely electronic waste based ferrite powder, iron sand, and toner waste are characterized according to their size and morphology (SEM), chemical elements (EDAX), chemical compound (XRD) and magnetic properties (VSM). The results are used as considerations to choose the mo

Abstract:

In this study, amorphous FeSiCrB alloy powder, carbonyl iron powder, and high-temperature heat-resistant silicone resin were used to prepare power molding inductors, and the effects of different heat treatment procedures on the magnetic properties were investigated. Two heat treatment procedures were used. Procedure 1: Amorphous FeSiCrB alloy powder was pre-heat-treated, then mixed with carbonyl iron powder and silicone resin and uniaxially pressed to prepare power inductors. Procedure 2: A mixture of amorphous FeSiCrB alloy powder, carbonyl iron powder, and silicone resin was uniaxially press

Abstract:

Coatings with flake carbonyl-iron powder as absorber and polyurethane resin as matrix were prepared. The complex permittivity, complex permeability and microwave-absorbing properties were investigated in the frequency range of 2–18 GHz. Both the complex permittivity and permeability of the flaky carbonyl-iron were increased compared to the spherical powders. The minimum reflection loss decreased and the matching frequency shifted to the lower frequency region with increase in the coating thickness. The band width can reach nearly 16GHz as the RL was below than-4 dB with thickness only 1.4 mm.

Iron containg hexagonal mesoporous silica particle ( Fe - MCM -41) was prepared and adopted into carbonyl-iron ( CI ) based magnetorheological (MR) suspension as an additive to improve the sedimentation problem of the CI based MR fluid. Structural properties and morphology of the synthesized Fe - MCM -41 particles were observed using SEM. Their MR properties such as oscillation characteristics and flow response (shear stress and shear viscosity) were examined via a rotational rheometer in parallel plate geometry equipped with a magnetic field supplier under external magnetic field strengths ra

Introduction: Iron deficiency represents a spectrum ranging from iron depletion to iron deficiency anaemia. In iron depletion, the amount of stored iron is reduced but the amount of transport and functional iron may not be affected. Iron deficiency is a major problem worldwide especially in women of reproductive age. Objectives: This study was designed to compare efficacy of two commonly used oral iron preparations among anemic pregnant women in private chamber of gynecologists and outdoor of Rajshahi Medical college hospital, Rajshahi, Bangladesh.

Abstract:

Bicyclic 1,2-diazepin-3-ones 1a-c, 2a, c are prepared by an iron carbonyl mediated reaction sequence from alkynes and cyclic 1,2-diazenes. The latter are first converted into hexacarbonyl diiron complexes which react with two molecules of an alkyne to afford tricyclic carbonyl iron compounds I -III. Oxidative degradation with bromine leads to these novel heterocycles whose structure is confirmed by an X-ray analysis of 1b.

Abstract:

Fe-catalyzed direct transformation of benzylic amines into carbonyl compounds was performed in H2O. The reaction of benzylic amines with formaldehyde in the presence of FeCl3·6H2O in H2O afforded the corresponding carbonyl compounds (80 °C to reflux conditions; 14 examples, up to 94% yield). O18-labeling experiments indicated that the O atom in the generated carbonyl is derived from H2O.

Abstract:

Peptide iron chelate is widely regarded as one of the best iron supplements for relieving iron deficiency. In this study, a new type of walnut peptide iron (WP-Fe) chelate was prepared using low molecular weight walnut peptides (WP) as raw materials. Under the conditions of this study, the chelation rate and iron content of the WP-Fe chelate were 71.87 ± 1.60% and 113.11 ± 2.52 mg/g, respectively. Fourier transform infrared spectroscopy (FTIR), zeta potential, amino acid composition, and other structural analysis showed that WP-Fe is formed by the combination of carboxyl, amino and carbonyl wi
