The effect SiC particle sizes (3 µm, 9 µm 29 µm and 45 µm) at 2.5% weight content on the corrosion resistance of 1060 aluminum in sulfate and sulfate-chloride solution was studied by potentiodynamic polarization, open circuit potential measurement and optical microscopy. Results showed the p...

As widely used Al-based coagulants, poly aluminum chloride (PAC) and aluminum sulfate (AS) were adopted in a short term at the start-up stage (from 10th to 16th) to enhance the formation of aerobic granules, and their effects on aerobic granulation were elucidated. The results suggested that bot...

Ferrihydrite (Fh) is a nanocrystalline iron (hydr)oxide pervasive in various surface environments. It has high specific surface areas and high density of reactive surface-sites, both of which properties impart a consequential role in determining the fate and transport of environmental nutrients ...

This study investigated the cooling crystallization of aluminum sulfate to explore the basic data for the recovery of aluminum resources from coal spoil. First, the metastable zone width (MSZW) of aluminum sulfate was reported. A parallel synthesis platform (CrystalSCAN) was used to determine th...

There are some drawbacks, such as bleeding, poor cohesiveness, etc, because the water to cement (W/C) ratio of dry-mixed masonry mortar is greater. Therefore, the influences of the slaked lime and aluminum sulfate on performances of masonry mortar were studied. The results show that the optimum ...

In order to obtain a deep understanding of the hydration of sprayed concrete, C3S pastes with and without aluminum sulfate (AS) were comparatively investigated. The results showed that AS significantly accelerated the hydration of C3S and refined the pore structure of the hardened C3S paste, by ...

Hydrogen peroxide (H2O2) detection was electrochemically performed using a non-enzymatic cobalt(III) complex (2) of an amidomacrocyclic ligand (1). We have characterized the metal complex using analytical techniques such as 1H NMR and ESI-MS and the composite material of the catalyst supported o...

The ammonium cation interaction with Na-birnessite in aqueous alkaline medium was studied. Solution and solid analysis give evidence that birnessite is not only acting as a cationic exchanger toward NH4+. The surface analysis performed by XPS showed that N1s spectra are characterized by the exis...

Single crystal electron paramagnetic resonance (EPR) studies of Cu(II) doped cobalt ammonium phosphate hexahydrate have been carried out from 300 to 77 K, with single crystal rotation in all the three planes at 153 K, since the spectra are well resolved at this temperature. The angular variation...

The ammonium–cobalt–nickel phosphates, NH4[Co1−xNixPO4]·H2O (x=0.00, 0.34, 0.59, 0.70, 1.00), and the deuterated forms, ND4[Co1−xNixPO4]·D2O (x=0.00, 0.38, 0.48, 0.69, 0.85), have been synthesized under mild hydrothermal conditions and characterised using X-ray and neutron diffraction, chemi...

An effecient synthetic method for fluorinated tridentate β-aminoenones and tetradentate bis(β-aminoenones) via amination of fluorinated 1,3-diketones with o-phenylenediamine in the presence of trialkyl borates was developed. Ni(II), Cu(II) and Pd(II) complexes with tetradentate bis(β-aminoeno...

New N-(substituted)-2-[4-(substituted)benzylidene]hydrazinecarbothioamides were designed, synthesized and evaluated for anticonvulsant activity and neurotoxicity. The anticonvulsant activity was established in three seizure models i.e. MES, scMET and 6 Hz model. The most active compound was N-(4...

Propargylamine and 2-butynamine were reported to serve as mechanism-based inactivators of the copper-containing bovine plasma amine oxidase (BPAO). Here, Ar– or Ar–X-extended analogs (X=NH, O, S) of these small molecules were synthesized and evaluated as BPAO inhibitors. 4-Phenoxy-2-butynamine...

6-(Perfluoroalkyl)salicylates were prepared by [3+3] cyclization of 1,3-bis(silyl enol ethers) with 3-ethoxy-1-(perfluoroalkyl)prop-2-en-1-ones.

Oxidative photocyclization of 1-phenyl-2-(2-arylethenyl)-3,3-dimethyl-3H-indolium perchlorates leading to 7H-indolo[1,2-a]quinolinium salts was investigated. The synthesis was performed under Vis irradiation. Blue LEDs emitting at 454.5 nm were used as the light source. The reaction progress was...

A new aryl ketone 1-[2′,4′-dihydroxy-3′-(3″-methylbut-2″-enyl)-5′-(1‴-ethoxy-3‴-methylbutyl)-6′-methoxy]phenylethanone was isolated from the leaves of Acronychia pedunculata. Its structure was determined directly by two-dimensional NMR spectroscopy and by comparison with the known compoun...

New fluorescent switches with 2,3-diarylcyclopent-2-en-1-ones as the photochromic component and 6-ethoxy-3-methyl-1H-phenalen-1-one as the fluorophore have been prepared. Two approaches to develop the photoswitches have been applied. The first involves covalent binding of the fluorophore to phot...

A chalcone derivative namely, (E)-3-(4-ethoxy-3-methoxyphenyl)-1-phenylprop-2-en-1-one (1v) has been synthesized and characterized on the basis of its spectral data.
