A hydrid coating composed of dicalcium phosphate dihydrate (DCPD) and poly(lactic-co-glycolic acid) (PLGA) is prepared on AZ31 Mg alloy to control the corrosion resistance. The DCPD coating is deposited on the AZ31 substrate by electrochemical deposition and subsequently covered by the PLGA coat...

CMA (calcium magnesium acetate) road deicers have gained popularity in recent years as an environmentally friendly alternative to traditional rock salt, and as an industrial adsorbent for removing H2S and other odorous acid gases from gas streams. Despite its increasing commercial use, its exact...

Large bone defects or fractures must be treated with an implant or transplant. Resorbable implants are attractive as these require only one surgery, whereas bone autografts, which can be cut off from the same person's hip, require more than one procedure. Moreover, porous structures promote...

In this paper, forsterite production via reaction sintering technique was presented. Experimental studies consist of three steps. In the first step mixture containing 57.62% serpentine, 42.38% magnesium chloride-water solution was first calcined in a furnace for chloride removal, ground and then...

The objective of this study is to investigate the variability in physiochemical and spectral properties of commercially available vegetable-grade magnesium stearate (MgSt) samples and to assess the correlation between physiochemical properties and near-infrared and Raman spectroscopic features t...

Magnesium chloride hydrate can be dehydrated to some extent by heating. However, it is not possible to fully dehydrate magnesium chloride by heating in air because of hydrolytic decomposition. Accordingly, the dehydration should be carried out in hydrogen chloride gas atmosphere. However, this p...

Pure Magnesium chloride hydrates are exceptional materials for long term thermochemical heat storage. In a heat storage cycle, the material is charged by dehydration, taking up heat, and discharged by hydration, generating heat. On charging, the H2O molecules released by the dehydration reaction...

The kinetics and mechanism of the isothermal decomposition of magnesium chloride dihydrate in nitrogen have been studied between 623–803 K. The principal products of reaction were identified as MgO and HCl: the progress of reaction was monitored by titrating the acid evolved with standard alkal...

Previous studies have reported that hydroxylamine (NH2OH) is an inevitable intermediate of the ammonium (NH4+) oxidation pathway under aerobic conditions. In this study, Pseudomonas putida Y-9 was found to oxidize ammonium into N2O via NO without the accumulation of NH2OH and NO2− under aerobic ...

A fast low-temperature phosphating processing accelerated by an ECO-friendly hydroxylamine sulfate (HAS) is developed. The zinc phosphate coating was fast formed on high-carbon steel in a low-temperature phosphating bath. Growth stages and characteristics of the phosphate coating were investigat...

In this work, porphyrin-based 2D MOF CuTCPP/platelet ordered mesoporous carbon (pOMC) composites were successfully synthesized by conventional solvothermal reaction. The introduction of pOMC increases conductivity of CuTCPP/pOMC composites, weakens accumulation of the CuTCPP layers, and exposes ...

The decontamination of prometon (PMT) by ozone/hydroxylamine hydrochloride (O3/HAC) was systematically investigated in this study with focus on the degradation mechanism and kinetics. Experimental results revealed that there was an enhancement of PMT degradation efficiency by 42.1% and the pseud...

Stereochemical results obtained from the concomitant reduction and desulfinylation of 1-phenyl-2-pyridyl-2(p-tolysulfinyl)- and 1,2-diphenyl-2-phenylsulfinyl ethanols with lithium aluminum deuteride reveal that the reactions proceed stereospecifically via σ-sulfurane as a common intermediate.

Temperature dependence of acoustic attenuation and non-linearity parameters in lithium hydride and lithium deuteride have been studied for longitudinal and shear modes along various crystallographic directions of propagation in a wide temperature range. Lattice parameter and repulsive parameters...

A search for excess heat production from highly loaded deuterides of palladium was carried out using a closed isoperibolic calorimeter. The main aim of these studies was to test the hypothesis that the production of excess heat from electrolytically prepared deuterides of palladium only occurs w...

ZrNi5 deuteride was synthesized at a high deuterium pressure of 0.9 GPa and at 373 K. Neutron diffraction study has revealed that ZrNi5D0.96(4) crystallizes in a monoclinic structure (Cm space group) between 1.8 and 220 K. The D atoms are located in one trigonal bipyramid Zr2Ni3 interstitial sit...

Lithium deuteride (LiD) was exposed to air for 600 min to determine the effect of air humidity on its microstructure and phase composition. XRD and XPS results revealed that LiOH and Li2CO3 formed at relative humidity values of >30%, whereas only LiOH formed at values

Pseudomonas putida, Aspergillus niger, Bacillus subtilis, Pseudomonas flourescens, Sphingomonas herbicidovorans and Rhodococcus rhodochrous growing on glucose in a medium containing one of three chlorophenoxy acids at a concentration of 0.1 g L−1 (clofibric acid, (R)-2-(4-chloro-2-methylphenoxy)...

To increase the specific surface area (SSA) of monolith-based adsorbent for the extraction of phenoxyacetic acid herbicides (PAAs) in complex samples, graphene was embedded in an adsorbent based on poly (4-vinylpyridine-co-ethylene glycol dimethacrylate) monolith (GEM). The new adsorbent was emp...

In the present study, a fluorescent optosensor containing a molecularly imprinted polymer in combination with electrospinning was employed for selective recognition of 2,4-dichlorophenoxyacetic acid (2,4-D). Free radical polymerization was carried out on the surface of polyethersulfone (PES) nan...
