ZnO was incorporated into nano particles of clinoptiloite by ion exchanging the zeolite in a zinc nitrate aqueous solution followed by calcinations process. All raw and modified samples were characterized by XRD, FT-IR, DRS, TG-DTG, SEM, BET and TEM. The prepared catalyst was used in the photoca...

Phenylhydrazine (PHZ) treatment is generally used to enhance parasitemia in infected mice models. Transient reticulocytosis is commonly observed in iron-deficient anemic hosts after treatment with iron supplementation, and is also associated with short-term hemolysis caused by PHZ treatment. In ...

Hepcidin, an iron regulatory peptide, plays a central role in the maintenance of systemic iron homeostasis by inducing the internalization and degradation of the iron exporter, ferroportin. Hepcidin expression in the liver is regulated in response to several stimuli including iron status, erythr...

Production of red blood cells involves growth-factor mediated regulation of erythroid progenitor apoptosis and self-renewal. During severe anemia, characterized by a strong fall of the hematocrit followed by a recovery phase, these controls allow a fast recovery of the hematocrit and survival of...

The development of multifunctional materials, specially nanocomposites, exhibit new and interesting properties which can extend the applicability ranges to diverse fields. In this way, the use of tri metallic nanoparticles, and derives, demonstrated higher efficacy for purification, catalytic ac...

The synthesis of a potent carcinogen, N-nitroso-N-methylaniline, employing a bis(dimethylglyoximato)cobaltate template is described. Carbon bonded N-methyleneaniline adducts of cobaloxime with pyridine, NO-2 or CN- in the basal (sixth) coordination position of the cobalt atom were prepared and i...

The adsorption and thermal decomposition of N-methylaniline (NMA) on the Pt(1 1 1) surface has been studied with reflection absorption infrared spectroscopy (RAIRS), temperature programmed desorption (TPD), and X-ray photoelectron spectroscopy (XPS). NMA adsorbs molecularly at 85 K through the n...

The mechanism of the C-N bond cleavage in hydrodenitrogenation over NiMo/γ-Al2O3 and Mo(P)/γ-Al2O3 catalysts was studied. The major part of C-N cleavage of o-toluidine takes place via ring hydrogenation and β-Hofmann elimination. Direct conversions from o-toluidine to toluene and from methylc...

The hydrodenitrogenation (HDN) of methylcyclohexylamine was studied over sulfided NiMo/γ-Al2O3. 2-Methylcyclohexylamine (MCHA) is an intermediate in the HDN of toluidine that can be detected in addition to the main products, methylcyclohexene (MCHE) and methylcyclohexane (MCH), when a high quan...

In order to detect cyclohexylamine and N-methylcyclohexylamine simultaneously in urine, a gas chromatographic method was developed in which Chromosorb 103 (porous polymer) was found to be suitable as the column packing. The detection limits were 0.1 μg/ml of cyclohexylamine and 0.4 μg/ml of N-...

Excess volume (VE123) and speed of sound (u123) data for three ternary mixtures, containing N-methylcyclohexylamine and nitrobenzene as common components and 1-alkanols, namely, 1-propanol, 1-butanol or 1-pentanol as non-common component were reported at 303.15 K. The experimental speeds of soun...

A novel absorbent was developed using an oil/water (O/W) emulsion absorbent with lipophilic amine. N-methylcyclohexylamine (MCHA) and 2,6-dimethylpiperidine (DMPD) were selected as the absorbents and Tween 80 was used as the emulsifier. The absorption rate and equilibrium were measured using a w...

Speciation and kinetics of carbon dioxide absorption by N-methylcyclohexylamine (MCHA) and 2,6-dimethylpiperidine (DMPD) emulsion absorbents were evaluated. The physical solubility, diffusivity, and carbon dioxide absorption rate were measured as a function of temperature (293, 303, 313, and 323...

In this work, densities, ρ and refractive indices, nD of N-Methylcyclohexylamine + 2-alkanols have been measured over the entire range of composition at four temperatures 298.15, 308.15, 318.15 and 328.15 K and ambient pressure (81.5 kPa), using Anton Paar DMA 4500 oscillating densimeter and An...

Three known iron(II) complexes bearing a bipyridine ligand, [FeCl2(bpy)2] (1), [FeCl2(bpy)]2 (2) and [FeCl2(dmbpy)] (3) (bpy = 2,2′-bipyridine and dmbpy = 6,6′-dimethyl-2,2′-bipyridine) were employed for the cross-coupling reaction of bromocyclohexane (4) with phenylmagnesium bromide (5). The...

The substitution of diethylzinc by phenylmercuric chloride is first order in each reactant, with k2 = 0.64 l·mole−1·sec−1 in solvent tetrahydrofuran, and with k2∼6 l·mole−1·sec−1 in solvent ether, both at 0°. The relative rate constants for substitution by phenylmercuric chloride in ether ...
