The solid–liquid equilibrium diagrams of binary mixtures involving magnesium nitrate hexahydrate with cobalt nitrate hexahydrate, nickel nitrate hexahydrate (partly), manganese nitrate tetrahydrate, and iron(III) nitrate nonahydrate and of magnesium chloride hexahydrate with cobalt and nickel c...

Three tensimetric methods were used to measure the equilibrium water vapour pressure for the reaction MnCl2 · H2O(s) = MnCl2(s) + H2O(g) over the temperature range (353.25 to 500.3) K. Two additional effects were considered, viz. possibility of a hydrate super disperse phase formation and proba...

The properties of six newly synthesized reagents for extraction of metal ions [Co(II), Ni(II) and Mn(II)] in chloride media were investigated, and the results with the standard extractants such as Cyanex 272, Cyanex 301, Ionquest 801 (DE2HPA) were compared. From these experimental results, a phy...

The recovery of manganese metal from manganese chloride medium by purification–electrorefining was studied. The ammonium chloride – manganese chloride electrolyte was selected as the most promising for refining. The physical properties of the electrolyte were first studied as a function of sol...

Densities (ρ), sound velocities (u), and viscosities (η) of glycine, dl-α-alanine, dl-α-amino-n-butyric acid, l-valine, and l-leucine, in aqueous solutions (0.1, 0.5, 1.0, and 1.5) mol · kg−1 of manganese chloride tetrahydrate, MnCl2·4H2O at different concentrations have been determined us...

Hydrogels are appealing biomaterials for applications in regenerative medicine due to their tunable physical and bioactive properties. Meanwhile, therapeutic metal ions, such as magnesium ion (Mg2+), not only regulate the cellular behaviors but also stimulate local bone formation and healing. Ho...

In this work, a novel microencapsulated phase change material based on sodium thiosulfate pentahydrate as core and poly(ethyl-2-cyanoacrylate) as shell was successfully synthesized by interfacial polymerization in a water-in-oil emulsion system. The morphology, microstructure, surface elemental ...

Potassium pyrophosphate was applied as stripping solution in osmotic distillation of fruit juices. The permeate ranged between 0.56 and 1.45 kg/m2h, being more sensitive to the variation of the feed temperature. After pre-saturating the experimental apparatus, no significant effect on the degrad...

This paper reports on the luminescence properties of Dy3+-doped 30SrO–30MgO–40P2O5, which had been prepared by solid state reaction. The crystalline phases were identified using X-ray diffraction (XRD) and their luminescence properties were studied using excitation and emission spectra obtaine...

Two series of glasses were produced by systematically substituting magnesium for calcium and strontium in the glass compositions, 4.5SiO2. 3Al2O3. 1.5P2O5. (3-x)CaO/SrO. xMgO. (2-y)CaF2/SrF2. yMgF2, 0 ≥ x ≥ 3, 0 ≥ y ≥ 2 and these glasses were characterised by 19F, 31P, 27Al, and 29Si MAS-NMR...

The magnesium pyrophosphate particle (MgPP) is a unique and safe carrier that is prepared by simply mixing magnesium chloride and sodium pyrophosphate. In this study, we investigated whether MgPP can be used to deliver nucleic acid–based adjuvants to immune cells. Polyriboinosinic-polyribocytid...

Phosphate is one of the main contaminations in water, so an effective method of decreasing or removing phosphate is needed. The main purpose of this paper is to synthesize CaFe-LDHs and MgFe-LDHs from the mixture of calcined dolomite and ferric chloride to remove orthophosphate and pyrophosphate...

Direct nickel electrodeposition on a Mg alloy, AZ31B, was conducted in an electrolyte containing potassium pyrophosphate, nickel sulfate, potassium fluoride and ammonium hydroxide. The effect of potassium fluoride on the Mg alloy in a pyrophosphate nickel electrolyte was investigated using polar...

This study aimed to establish the influence of protein oxidation on the ability of magnesium pyrophosphate (PP) to dissociate actomyosin. Actomyosin isolated from pork muscle then suspended in 0.1 M NaCl at pH 6.2 was oxidatively stressed with 10 μM FeCl3/0.1 mM ascorbate/1 mM H2O2 for 6 or 12 ...

In this work, a series of Dy3+ (0.25, 0.5, 1, 1.5, 2, 2.5 mol. %) doped Mg2P2O7 phosphors were synthesized via solution combustion method. The crystal structure and phase purity of phosphor were identified by X-ray diffraction technique. The lattice parameters was obtained from Rietveld refineme...

Magnesium phosphates such as newberyite (MgHPO4·3H2O) are formed in vivo and are known to be biodegradable and nontoxic after implantation. Indeed, magnesium apatites have been shown to support osteoblast differentiation and function, and bone formation can occur around metallic magnesium impla...

Perchlorate and chloride salts on Mars could readily absorb water vapor and deliquesce into aqueous solutions. The deliquescence relative humidity (RH) as well as the efflorescence (recrystallization) RH of several Mars-relevant salts are now well known; however, the conditions that could cause ...

The dehydration and thermal decomposition kinetics of magnesium perchlorate hexahydrate have been studied using thermograviinetric analysis, differential scanning calorimetry and x-ray diffraction techniques in conjunction with isothermal gas evolution vs. time measurements. For Mg(ClO4)2-6H2O d...

Arrested reactive milling is used to prepare a composite thermite powder combining magnesium metal with calcium iodate, Ca(IO3)2. Upon ignition, this material generates iodine, a biocidal species capable of effective inactivation of aerosolized microorganisms. The prepared material is metal-rich...

There is a growing interest on glycol-split low-molecular weight heparins (gs-LMWHs), obtained by periodate oxidation of LMWHs, optionally followed by borohydride reduction, as potential anticancer and anti-inflammatory drugs. However, their structural characterization is still a challenging tas...
