In this study, the effects of the addition of carbonyl nickel powder on the density, microstructure, and mechanical properties of sintered yttria-stabilized zirconia (3YSZ) were investigated. Sintering at 1300 °C resulted in the optimum comprehensive mechanical properties. The addition of 5 vol...

The dissolution mechanism of nickel grown by the carbonyl process was investigated using laboratory Ni samples. These samples were purposely engineered to form an alternating lamellar structure of Ni layers grown under two limiting conditions. Three layers deposited from low nickel carbonyl gas ...

Recently, oxidative stress is strongly associated with lead (Pb)-induced neurotoxicity. We reported previously that Astragaloside IV (AS-IV) possesses potent antioxidant properties. Here, we evaluate the hypothesis that AS-IV attenuates lead acetate (PbAc)-mediated inhibition of neurite outgrowt...

The introduction of hybrid perovskites is revolutionizing the field of solution processable next-generation optoelectronic devices, with outstanding results achieved in solar energy conversion devices, lasing, light emitting diodes, and thermoelectric generators. An intelligent design of the mat...

A new graphene nanocomposite, CeO2-poly(diallyldimethylammonium chloride)-graphene (CeO2-PDDA-GR), was prepared by an easy and low-cost hydrothermal method. The images of transmission electron microscopy (TEM) showed that well-shaped CeO2 nanoparticles distributed more uniformly on the GR sheets...

A novel electrochemically activated nanocomposite, CoS2 Nanoparticles and MoS2 Nanosheets decorated poly(diallyldimethylammonium chloride)-functionalized graphene (CoS2-MoS2-PDDA-GR), was successfully synthesized through a simple and low-cost method. X-ray diffraction (XRD), Transmission electro...

Eriocitrin is a flavanone glycoside which exists in lemon or lime citrus fruits. It exhibits antioxidant, anti-cancer and anti-allergy activities. β-casein is important protein in bovine milk, under appropriate conditions, it can form stable micelle like structures in aqueous solution, which is...

Eriocitrin is a flavonoid that is isolated from orange peel. Resveratrol is a polyphenol compound, which is present in various fruits, such as grapes. The aim of the present study was to investigate both in vitro and in vivo anti-inflammatory effects of eriocitrin combined with resveratrol using...

Sulfur- and selenium-containing amino acids are of great biological importance, but their metal-binding properties with biologically-relevant metal ions are not well investigated. Stability constants of the methionine, selenomethionine, methylcysteine, and methylselenocysteine with Cu(II) and Fe...

The magnetic properties of previously unexamined MnBr2·2H2O, MnBr2·H2O, MnBr2·2D2O and MnBr2·D2O are studied. Curie–Weiss fits to high temperature data yield θ of −13.1, −3.9, −8.2 and −5.0 K, respectively, in χM=C/(T−θ). The net antiferromagnetic exchange yields susceptibility maxima at...

Ionic clathrate hydrates are composed of water and ionic guest substance, which can selectively capture gas under moderate conditions. We performed gas separation experiments with tetra-n-butylammonium bromide (TBAB) widely-used for an ionic guest substance. The experiments in a closed system sh...

In this study, we have reinvestigated the thermal decomposition kinetics of iron(III) phosphate dihydrate FePO4∙2H2O in air atmosphere by TG/DTG and DTA techniques using non-isothermal experiments. The apparent activation energy Eα was determined by the differential and integral isoconversional...

Solution growth at a higher temperature to grow the paraelectric phase and at a lower temperature to grow the antiferroelectric phase of various deuterated crystals of ammonium dihydrogen arsenates (NH4(1−x)D4xH2(1−x)D2xAsO4), DADA crystals is described. The dielectric properties around the phas...

Single crystals of ammonium dihydrogen arsenate, NH4H2AsO4, were subjected to electrolysis during which hydrogen gas was detected. Quantitative and qualitative determinations were made which indicate that Faraday's law is obeyed for the transport of ions through the crystal. Other single cr...

The metal-organic framework (MOF) UiO-66-NH2 was synthesized with different substrate to solvent ratios and its morphology, surface area, pore distributions, and NMR, XRD, and TGA-FTIR patterns were obtained. Adsorption tests at pH 7 and 25 °C showed that the produced UiO-66-NH2 has a hydrogen ...

SummaryFunctionalized alkyl iodides are important compounds in organic chemistry and biology. In this communication, we developed an interesting nickel-catalyzed carbonylative synthesis of functionalized alkyl iodides from aryl iodides and ethers. With Mo(CO)6 as the solid CO source, both cyclic...

The electrochemical oscillations of bromates on the stationary mercury electrode can arise, if in a solution of sulfuric acid or nitric acid besides sodium bromate also bromine is present. The origin of the anodic current oscillations is explained on the basis of described results by means of a ...

The use of elemental mass spectrometry as detection for ion chromatography allows sensitive determination of several bromine and iodine species at a reasonable time scale. Lowest concentrations observable are 66 ng L−1 for bromate, 45 ng L−1 for iodate, 74 ng L−1 for bromide and 151 ng L−1 for i...
