Cadaverine, also known as 1,5-pentanediamine, is an important platform chemical with a wide range of applications and can be produced either by fermentation or bioconversion. Bioconversion of cadaverine from l-lysine is the preferred method because of its many benefits, including rapid reaction ...

Dispersion of inorganic (magnesium chloride) nanoparticles in oil (octyl palmitate) was obtained by modifying a method based on solvent evaporation from nanometric droplets of water-in-oil nanoemulsion, which is usually used for obtaining organic nanoparticles. The particles size depends on the ...

This work reports the synthesis, characterization, and cytotoxicity of biogenic magnesium oxide nanoparticles (MgONPs) and nanosilver embedded magnesium oxide nanoparticles (Ag-MgONPs). The formation of nanoparticles (NPs) was confirmed by the indications of color changes and precipitations. Fie...

Solubilities of the ternary system MgCl2–MgBr2–H2O at T=(288.15, 308.15, 323.15 and 333.15) K were investigated, and the crystallization behaviour of solid solution Mg(Cl,Br)2·6H2O was established. Combining our experimental results with other experimental data available in the literature at ...

The liquidus of the phase diagram of MgCl2·6 H2O+MgBr2·6 H2O mixtures was determined, and a continuous series of mixed crystals was found to be formed on freezing. The freezing point of MgBr2 · 6 H2O was confirmed to be 164.4±0.3°C, but on repeated melting—freezing cycles this value decrea...

Nonaqueous liquid electrolyte system based dimethyl sulfoxide DMSO and magnesium bromide (MgBr2) is synthesized via ‘Solvent-in-Salt’ method for the application in magnesium battery. Optimized composition of MgBr2/DMSO electrolyte exhibits high ionic conductivity of 10−2 S/cm at ambient temper...

We investigated the effect of bicarbonate and oxidizing agents on uranium (U) reactivity and subsequent dissolution of U(IV) and U(VI) mineral phases in the mineralized deposits from Jackpile mine, Laguna Pueblo, New Mexico, by integrating laboratory experiments with spectroscopy, microscopy and...

The determination of Mo(VI) in water samples by electroanalytical techniques has been studied previously. Special attention has been paid to catalytic adsorptive stripping voltammetry (cAdSV) due to the high sensitivity and low detection limits achieved with this technique. In this work, a fast ...

This paper reports the results of a study on the determination of the protonation constants of MoO42 −, in NaClaq, NaNO3aq, KClaq, at different ionic strengths (0

Microwave-induced catalytic system has been widely used in oxidation of organic pollutants, but no report focuses on heavy metal reduction. To expand the application field of microwave-induced catalytic system, MoS2 decorated MnFe2O4 was synthesized by hydrothermal method and employed for the re...

A novel poly(N1,N1,N6,N6-tetraallylhexane-1,6-diammonium dichloride) (PTAHDADC) microparticle was prepared via inverse emulsion polymerization. The adsorption characteristics and mechanism for Mo(VI) in an aqueous solution were investigated systemically. Results showed that PTAHDADC had a high p...

Heavy metal pollution has become a global environmental problem. Industrial wastewater containing hexavalent chromium Cr(VI) is particularly harmful to the environment. Effective treatment of industrial wastewater containing Cr(VI) is still difficult. In this study, functionalized hybrid nanotub...

The separation of tungsten and molybdenum from solutions containing high concentrations of W(VI) and Mo(VI) using solvent extraction with a primary amine extractant N1923 was studied. W(VI) was selectively extracted over Mo(VI) by acidified N1923 at an equilibrium pH of 7.0. The extractant acidi...

The influence of growth conditions on the synthesis of cytochrome c552 and the activities of NADH-nitrite oxidoreductase (EC 1.6.6.4) and NADH-cytochrome c oxidoreductase (EC 1.6.99.3) have been studied in Escherichia coli strain K12. Nitrite added to anaerobic cultures stimulated cytochrome c55...

This paper is concerned with ion-exchange removal packed bed studies carried out with secondary effluent on a sewage treatment works. The work was carned out over a five month secondment period with Severn Trent Water, situated in the midlands of England. The objective of the work was to compare...

Quantitative determination of nitrite ion (NO2−) is of great importance in environmental and clinical investigations. A rapid visual and spectrophotometric assay for NO2− detection was developed based on a newly designed ruthenium complex, [Ru(npy)([9]aneS3)(CO)](ClO4) (denoted as RuNPY; npy = 2...

This study developed improved manganese oxide coated media based on the todorokite structure which are an effective means to remove a range of heavy metal ions from acid mine drainage (AMD) solutions. As a consequence, limitations of conventional acid mine drainage treatment wherein use of oxida...

Five tetradentate ligands, L1–5, bearing the moiety of bis(pyridin-2-ylmethyl)amine (1) and their complexes with Mn(II) were prepared. All the compounds and metal complexes were appropriately characterized. The five manganese(II) complexes (3a–e) are of the formula, [Mn(II)LxCl2] (x = 1-5), as...
